What You Really Need to Know About a MPLS Network

MPLS… or Multi-Protocol Label Switching…. seems to be the buzzword for connecting company data networks these days. But MPLS is really nothing new. It’s been around awhile actually. Maybe now it’s just gaining more popularity and thus noticeable public acceptance and notoriety. Rightfully so too. MPLS offers lots of advantages over traditional T1 point-to-point WAN architectures.

But….. to decide if MPLS is really a good fit for your network requirements….. there’s some things you need to understand first.

There’s no one “MPLS Service”. A lot of what you get will depend how the service provider has Engineered and built their core network. Bear in mind that many carriers don’t own the whole network, but will piece together a service from other carriers networks, or will interconnect with other carriers to extend their reach.

Cell-mode MPLS was mentioned: basically this is ATM which has been retro-fitted with MPLS. Be careful with this for VoIP applications because it can use bandwidth very inefficiently.

MPLS can support QoS, but many services aren’t engineered with this, or only with very basic prioritization. Also the services are very often structured to reduce the potential complexity and to ensure the network can cope. Bear in mind a typical MPLS router can only carry a percentage of “high-priority, real time” traffic. If everyone sends all their data as high priority then the benefit is lost, and the network may suffer. Usually QoS is provided as a small number of service classes, typically 3 or 4.

The biggest bottleneck in any such service is normally the tail circuit to each of your premises. If you move from a T1 mesh to a MPLS service then you will likely find that some sites need more bandwidth than others. Tracking the requirement for this bandwidth is usually your problem, although the service provides may give you some reporting tools to assist with this. I would avoid service providers who cannot offer this as it will make it very difficult for you to manage your bandwidths.

If you factor in multiple service classes then your management of these tail circuits gets more complex as you no only have to work out how much bandwidth is required for each tail circuit, but how much of it should be reserved for each service class.

Regarding resilience, within the service providers core, the service is normally highly resilient to failures. However, when failures do occur, very often (depending on how the service is engineered) the rerouting can take a second or two. During this network re-convergence you will lose packets. Depending on the protocol your traffic uses this can be unimportant or devastating. For instance, some VPN and VoIP services don’t survive this well.

Normally resilience is not automatically provided all the way to the customer. Typically you will have one tail circuit and one router at each site. If either fails (or if the Service provider’s PE router has problems) you will lose service to the site, totally.

If this is an issue, you need to factor in dual connections. There’s multiple ways of doing this, and different service providers will offer different options. Make sure you get your Network Engineer involved as the devil is in the detail here, and some options which sound like they provide a fantastic level of resilience may not be as good as they sound, depending on how your internal network is configured.

And, of course, the key to all of this is SLAs: what do they offer? What happens if they break them? How do they report them to you?

Generally speaking, MPLS services are a great way to run a multi-site data network including VoIP services. I have seen many carriers and their customers doing this successfully for years.

Strictly speaking MPLS does not provide QoS. QoS is done by prioritizing traffic, and most IP routers, even those on the backbone of the Internet, can do this. The difference is whether they are configured to do this or not. In an MPLS network MPLS is provided by standard router features. MPLS technology (specifically Traffic Engineering) gives the carrier better control over how this traffic is prioritized and routed (and restored in case of network fault). All this does is give them the confidence to support SLAs.

As I mentioned, “QoS” is provided as a set of “service classes”. Typically these are things like “real-time”, “high-priority” and “everything else”. Mapping actual traffic into these classes can be done in a few different ways, but this is largely up to you to control. For instance, you could quite easily put web-browsing traffic into “real time” although this would normally be a dumb thing to do.

I would suggest the case for MPLS in terms of performance, cost and continuity against ‘traditional’ or ‘legacy’ data networks is now pretty robust, i.e. MPLS provides significant advantages in all 3 areas.

The key considerations when migrating include provider selection, access media (e.g. using Ethernet rather than SDH/SONET), the decision on procuring a managed or unmanaged service (often called wires-only) and the providers ability to map their CoS/QoS to the applications you need to support. This is especially important if you are operating any proprietary applications.

There is also an increasing trend to use WAN Optimization/application management solutions either as a value added service from the provider or from an alternative integrator or indeed doing it in house. This is important say for voice or applications such as CITRIX.

MPLS providers also now offer a whole suite of value added services such as integrated internet, managed network based firewalls and remote user support. If these are important to you make sure the providers demonstrate how this is achieved.

In selecting your provider ensure they have good geographic coverage in your areas and experience within your market segment. I always recommend requesting up to 3 references. Equally I think it is wise to understand how important a client you will be to the provider. It’s all well and good using the market leader (say according to Gartner)….. but you’ll often get a better service from a provider who values and really wants your business.

Genital Wart Facts

Genital warts are a type of wart that are only found on your private parts of the body. The genital wart is one that will be easily recognized. Genital warts are also known as veneral warts and also as condylmata acuminata. Warts in this manner are caused by a skin infection, which is known as PHV infection. It is possible to have the HPV infection without having genital warts. Genital warts are often passed along during sexual intercourse, but not all those who have genital warts are going to know they are infected until the warts are bigger and a little more painful.

Warts are a virus, that can be passed by touching, sitting and skin to skin contact. The most common types of warts are seen on people’s hands and feet, which are a different form of a wart but are generally the same thing if you are wondering what genital warts really are.

Warts are associated with the tumors that form under and in the skin. The tumors are forms of the HPV infection, and will form warts as the body rids the infection from the body. If you have warts on the hand or on the feet, you are not going to spread this to your genitals. If you know someone who has genital warts, they are not going to give you warts on your hands and the same goes the other way around.

For the woman, if you have genital warts, they will appear on the inside and the outside of the vagina. If the woman has anal sex, the genital warts could appear an the anus, and the same is for the man. If a man is having anal sex with another, the genital warts could appear on the anus area as well.

The warts will appear in the same area, taking a long time to spread out. Sometimes the warts will disappear on their own, but only in rare cases often times the genital warts will spread becoming crusty and become large areas of warts over the private areas of a male or female. If you have genital warts, and someone performs oral sex, the genital warts can be transmitted to that person. Genital warts can be treated by a doctor, and with medications. If not treated, often times genital warts can become troublesome not only for the person suffering with them, but for people you love and want to share that special relationship with.

If you have sex with someone that you later finds out has genital warts, you most likely are going to end up with genital warts are well. It can take any where from one month to three months for genital warts to appear and become large enough for a person to notice them. Always protect yourself by avoiding having sex with anyone you don’t know or trust not to have genital warts.

Motorcycle Automatic Transmission – The Top 3

Motorcycle enthusiasts love a wild goose chase such as the famously beloved, Bigfoot. Many motorcyclists fail to believe that there is actual automatic transmission motorcycles that exist. This is not true because the knowledge isn’t out there. This is actually true because of there just aren’t to many readily available. The top three automatic transmission motorcycles really exist and the proof is found by reading on.

3. The Honda DN-01

The Honda DN-01 was introduced in 2005 as a cruiser motorcycle. This is one of the first of very few automatic transmission motorcycles ever released. The bike didn’t actually make it on showroom floors until 2008-2009. This bike is so powerful to the consumer that it is still being offered in shops as of early 2011. Missing you chance to check out the Honda DN-01 is just wrong. The Honda DN-01 is just one of those bikes you can’t miss a chance to try out for yourself.

2. The Aprilia Mana 850

The Aprilia Mana is a newer automatic transmission motorcycle that was just released last year. This bike is fast and very powerful. The Aprilia Mana 850 is a sleek sports bike that offers highlights from leather to chrome and everything in between. There is nothing better than a quick bike with the backing of being an automatic transmission motorcycle. The Aprilia Mana 800 makes its way to this top three list for being a solid bike with an even nicer ride.

1. The Honda CB750

The Honda CB750 has had many models in its series between 1969-2003. The Honda CB750 automatic transmission models is better known as the Honda CB750 Hondamatic. This model is one of a kind that has a coil ignition start and a solid inline four stroke SOHC air cooled engine. The only downfall to this model was the fact that the gear changing was not automatic. Instead, each gear was chosen by a foot-controlled hydraulic valve. This bike only sold in the North American market but can now be found all over the world.

Learn How to Drive Online – Learn to Drive Easily

Learning to drive is not the easiest thing to do, especially if you are a young person. Whether you are young or a little older and trying to get your license, you need to be aware that it is possible to learn how to drive online.

The internet is a very powerful tool and just about anything can be learned on it very easily. Driving is no exception. While formal drivers education classes are certainly needed and highly recommended, there are resources online that can help you learn just as much or even more than you would from a regular in-person class.

The best product that I have ever come across to help people learn how to drive online is a video education course called Get Ready To Pass. I have done an in depth review of it and found it to be extremely effective.

The reason why I liked this product so much is because it gives the user all the tools that are needed to succeed and pass the road driving test the very first time. About half of people who attempt their road test fail on their first try. I know this because I was one of them!

I could have really used the resources given by this online drivers education website and helped myself be more prepared. It would have certainly been worth sparing the embarrassment I felt having to tell my friends that I could not drive good enough to pass.

In closing, it is totally possible to learn how to drive online if you want to. I recommend an online course that includes videos and has a solid customer base of people whom it has worked for. I know that I definitely could have used the help!

1. Meatloaf – Bat out of Hell

Released in 1979, and again in 1993 it was written by Jim Steinman with lead vocals from Meatloaf. Steinman was insistent that the song should contain the sound of a motorbike engine being revved, and complained to producer Todd Rundgren in the final recording session when it was not added. Rather than use a recording of a real motorcycle, Rundgren himself played the section on guitar, leading straight into the solo without a break.

The Top Three Benefits of Changing Transmission Fluid

There has always been some debate on the pros and cons of changing your transmission fluid on a routine basis, per your vehicle owner’s manual recommendation. One of the many rumored suspicions is that doing so will open your car up to having dreaded transmission issues sooner. To debunk those conspiracy theories, let’s get into the meat of the topic and explore, together, why it absolutely makes sense to change it regularly; and how not doing so could actually cause your car to run sluggishly – potentially costing you precious pennies in the long run!

1) Heat is the enemy

The number one reason that manufacturers recommend you change your transmission fluid regularly is because it degrades as it continually heats up during driving. There are exhaustive studies about the precise temperatures in which its effectiveness actually wanes. Suffice it to say that most owner’s manuals duly recommend changing your fluid every 30,000 miles. There is one exception to this rule: newer vehicles using Dexron III ATF fluid can often go up to 100,000 miles before needing to be changed. As you drive, and the transmission heats up, the viscosity of your fluid changes; over time, this heat causes transmissions to burn up and this is the single-most cause of transmission repairs today – burned up transmissions.

2) Gunk and sludge

As your transmission continues to heat up and it continues to break down, your car’s transmission components begin to get bogged down with gunk and sludge. You don’t need to be a rocket scientist to know that gunk and sludge are going to clog up your transmission gears, causing unnatural wear and tear on your vehicle’s transmission. If you want your transmission to continue to operate smoothly, it is vital to keep it clean.

3) Leaky seals and putrid odors

No, I’m not talking about a horror flick here. A well-maintained machine is one whose owner regularly checks the transmission fluid levels – yes, using the dipstick! You should ideally check your transmission fluid level when your engine is warm and idling. Transmission fluid should be bright red and should smell sweet, not putrid or rancid. It shouldn’t be brown or black or even dark red. It should look like the tip of the spindle after Sleeping Beauty pricked her finger. If your transmission fluid level is low, or the color is not right, it’s time to change your transmission fluid and check (or have checked by the mechanic) all of the seals around the transmission for leaks.

If you want your transmission to last throughout the life of the car, it is imperative that you change your transmission fluid regularly, following your owner’s manual guidelines and a few common sense rules. In today’s world of disposable everything – neglecting your transmission can be a rude awakening to your wallet. The potential costs associated with ignoring the routine maintenance guidelines on your transmission could total thousands of dollars that would be better spent on a nice, warm vacation to a sunny spot this summer.

Novel Ideas – Six Unique Ways to Introduce a New Novel to Your Class

There is nothing more exciting than introducing students to a great piece of literature. Conversely, there is nothing more disappointing than students’ lack of enthusiasm about a book you truly love. Unfortunately, your fervor about a novel does not always translate into cheers and applause on the part of your students. Reading a novel requires a lot of investment. Even novels with high-action plots take a while to build momentum. How can you quickly bolster students’ interest at the start of a new book? Below are six sure-fire ways to get your class excited about a new novel.

PLOT PIECES. Divide students into groups. Assign each group one page from a different part of the novel. After they have read the page, ask students to compose a paragraph that outlines the plot of the novel. To do this, students will have to use context clues gleaned from their excerpt. Ask students to elect a representative from each group to present their plot summaries. Compare plot summaries and revisit these summaries at the end of the novel. Asking students to conjecture the plot of the novel will pique their interest in the book and help them extract information from context clues.

FIRST IMPRESSIONS. Ask students to read the first page of text silently. Next, ask for a volunteer to read the first page aloud. Then, ask students to write down as many things as possible that they have learned from the first page. Next, ask students to write down three questions they have based on their reading of the first page. This activity will help students read context clues and it will teach them to site text evidence when making generalizations about a novel.

COVER UP. Read a summary of the novel from the back cover, from the inside flaps, or from an Internet source. If you prefer to leave the novel a mystery, read an excerpt from a select part of the book. You can also print out this summary or excerpt so that students can refer to it. Next, ask students to design a cover based on information gleaned from the summary or excerpt. Allow students to explain their cover design. If you are reading a novel that is divided into parts, have students design a cover at the end of each part of the novel. Revisit cover designs at the completion of the novel and ask students to write a paragraph discussing their various understandings of the novel. This activity will help students chart the ways their understanding developed throughout the reading.

FRONT MATTER. Though students read novels throughout their schooling, very few are taught the importance of the title, copyright, and acknowledgments. The pages that contain this information are called the “front matter.” In small groups, ask students to explore the front matter of the novel. Instruct students to list 10 things they learned from these pages. In a more open-ended version of this activity, you can ask students to answer the following questions: What does the front matter tell you about what will and what will not be in this novel? What does the front matter tell you about the novel’s plot and themes? A good explanation of front matter can be found at Vox Clarus Press’ website. Just search “Vox Clarus Front Matter.”

LAST LINES. Instruct students to read the last sentence or the last paragraph of the novel silently. Next, ask someone to read these last lines aloud. From these last lines, ask students to draw a comic strip that shows the plot of the novel. Each frame of the comic strip should contain narrative and dialogue. The last frame of the comic strip should be based on information gleaned from the novel’s last lines. Thinking about the ending of the novel will whet students’ appetite for the actual plot.

BEGINNING AND ENDING. Ask students to read both the first sentence and the last sentence of the novel. Next, ask the students to construct a poem, paragraph, or short story using the first and last sentences of the novel as the first and last sentences for their writing. Your students’ writing should summarize what they think will be the plot of the novel. Revisit these summaries at the middle and at the end of the reading. In a reflective paragraph, ask students to compare their initial impressions to the novel’s actual plot and themes.

When beginning a new novel, consider using one of the above activities in your classroom. These activities provide a new lens through which to view your new novel. Starting the study of your novel in a unique and unpredictable way will bolster your students’ interest and engagement.

Learning The “Secrets” of

Seeking For Chiropractic Solutions After An Injury

A common occurrence in the event of an accident is for the victims to suffer a range of injuries. While seeking for medical attention is the common option sought by majority, it does not provided with desirable results of full healing. The victim in this regard may consider seeking for chiropractic solutions that have capacity to provide with the healing levels desired by the victim. Through this treatment process the patient do not require to use modern medicine but benefit from a historical approach that has been in use for decades. The approach seeks to wake the body self healing capabilities and therefore ensure there is complete healing without using any form of drugs.

Injuries that result from accidents comes with the risk of affecting ones mobility. The victim in this regard lacks the strength and stability required to perform daily activities with ease. The victim in this regard get the opportunity to attain normal healing and in such way regain the strength and stability and strength that is required for the body. Alongside attending therapy sessions, the service provide also provides with guidance on the essential lifestyle for the patient to gain faster recovery.

Alongside healing, the body need to be full energized to perform effectively. With adequate energy, the muscles of the body also gain capacity to keep the body functional when need arises. The chiropractor therefore work to ensure one is guided in the process to grow adequate body muscles. Growing of the muscles comes with ensuring the victim engages in the rightful exercises and in the same way use the right foods to energize and help in growth.

Health of an individual comes with among other things the kind of lifestyles they lead. Features of a person’s lifestyle determines the type of health and in such way the need to ensure it fits to the best healing needs and maintenance f health thereafter. The chiropractor in this regard provides with guidance and planning to lead a healthy lifestyle for the patient. The planning process comes with consideration of the daily engagement of the victim to ensure they create the best healing platform. For a better health, it therefore comes as a big input that enables the victim to lead a better life and work in better conditions. The input therefore comes in handy to ensure the victim heals faster and further gain capacity to lead a healthy life.

Being a victim of an accident is a risk to every person. This includes the children as well as the elderly. Chiropractic services in this regard provides with a solution that comes in custom packages to cater for each individual needs. It means that each individual case with a patient is handled on its own. Among the important considerations in this regard includes the injuries suffered and the age of the patient. This seeks to ensure that complete and satisfactory healing comes into place.

Smart Tips For Finding

How You Can Choose the Best House Buying Company

It can be overwhelming to choose among the many house buying companies that are found out there. Let us look at the ways in which you can hire the best house buying company.

One thing that most of the people would like is for their house to fetch high prices. Because of that, you should check their offers before you commit to them. The thing that you will have to do is getting offers from multiple house buying companies and make the comparison. Doing this is beneficial as it will allow you to find a house buying company that will make you fetch high returns from your house. It is advisable that you should not go with the first offer as you may be missing some of the best deals. The other important thing is going with a company that does not charge you commission for real estate agents and they should allow you to pocket all the money generated from the sale of the house.

The second tip, for choosing the best house buying company is checking the types of houses they buy. This is vital as there are different types of houses such as villas, condos, residential real estate, commercial real estate and others. Thus why you need to verify that they can buy your type of house before you commit to them. Besides, there are also some companies that can buy all types of houses which will assure you that they will purchase a house.

Apart from that, many buyers always want houses that are in good condition. This way your house will take longer in the market. One thing that you should do is choosing a company that will purchase your house as it is. With such companies you will not have to clean or repair the house before you list it for sale. This will make you sell your house faster and also improve your savings.

The other thing that you should consider is their closing time. You need to know how long they will take to sell your house. One thing that will dictate this is how quickly you need the money. One thing that you will have to do is choosing a company that can close the deal within 24 hours so that you can use the money in handling emergencies.

Last but not least, you should also check their payment method. One thing that you need to do is choosing a house buying company that will pay you cash as waiting for the check to be approved by the bank will take longer.

Genital Herpes Symptoms and Treatment

Genital herpes is one of the most common sexually transmitted diseases in the world today. It is caused by the herpes simplex virus.  This is the family of viruses that causes cold sores, shingles, and chicken pox. 

Genital herpes is caused by infection with the herpes simplex2 virus (HSV2). HSV1 is the virus that causes cold sores on the lips and nose area. The herpes virus, however, is not too particular about the mucous membrane it calls home and will happily live in either the mucous membranes of the mouth and lip area or the reproductive tract.  Because of this, oral genital contact can spread either HSV1, HSV2. Viral transmission can occur from the mouth to the genitals or from the genitals to the mouth. The blister type lesions caused by either virus are virtually identical.

Genital Herpes Symptoms

Sometimes after the initial infection there may be fever and general malaise as could be seen with any acute viral infection but this is not always apparent in all cases.  In fact the symptoms of a genital herpes infection may not be known to you until you see some blisters on or around your genital area. 

This is called an outbreak and is characteristic of the way the herpes virus acts in the body. There will be periods when the virus is dormant and none of the characteristic symptoms of genital herpes are present.  Then there will be these outbreak periods where blisters appear in the genital area and may even extend to the anal area. 

The blisters will act like any normal cold sore on the lips.  They come up with an initial tingling, then grow larger and spread and eventually burst leaving an ulceration that will slowly heal on its own.

In men these blisters occur on or around the penis.  In women the blisters may actually be in the vagina as well as on the surrounding genital area. 

Symptoms of genital herpes will come and go but the virus stays with you forever. The number of outbreaks will gradually become less and less and in some cases, some people do not see outbreaks at all.   

Diagnosis

You may not know you have contracted genital herpes until the first breakout of the blisters. Symptoms of genital herpes are so mild in some people they think they just have a skin irritation.  The best thing to do is to be checked by a doctor so that you can get diagnosed properly. 

Doctors can usually make the diagnosis based on inspection of the genital area as the lesions are quite specific in appearance.  In some instances the doctor may take a swab on the blister fluid to see if it contains the virus.

Genital Herpes Treatment

There is no cure for genital herpes, however, it can be controlled so that you can live a normal sexually active life.  Anti-viral medications are often prescribed at the first outbreak to knock back the infection and may be used for prolonged periods if outbreaks are frequent.

Other treatments for the discomfort of an outbreak are common sense measures such as wearing loose comfortable clothing, using cold compresses or soothing creams and ointments on the blisters.

A strong and healthy immune system is needed to keep the virus suppressed and to reduce the frequency of outbreaks. Health denying habits such as smoking, drug use, or toxic relationships will drain the resources of your immune system so your best method of treatment is to maintain good health.  This would include eating whole nourishing foods, getting plenty of exercise, and managing stress. 

Complications

Generally the herpes simplex virus is not considered a dangerous infection to persons who have a fully functioning immune system. The virus will be suppressed and outbreaks will not be common as long as the immune system is functioning well.

However, if the immune system becomes burdened or compromised in any way then outbreaks will be more likely to occur.  This may happen during times of physical or emotional stress.  If the immune system is comprised by other more serious illnesses such as HIV or cancer then the herpes virus can become more dangerous.

If the virus is directly transmitted to other areas such as the eyes, or the brain, complications can be very serious. This direct transmission can happen in a number of ways but the most common is during the birth process.  The infant can become infected with the virus from contact with the mother’s vagina during birth.

If you suspect you may have contracted a genital herpes infection see your doctor as soon as possible.  Never have sex during an outbreak and never have unprotected sex. This means using a condom  (either male or female type)  during every sexual encounter even during oral sex. 

Additionally you should always inform your partner of your herpes status.  This is always the right thing to do.
