- Buying an Internet Connection is a lot like buying a computer. As with
- buying a computer, your choice of Internet providers should be driven
- by your intended use. If you are looking for a minimum cost, bare bones
- computer for your kids, you might seek out the lowest priced system in
- the back of a magazine or even assemble something yourself from parts
- bought at a flea market. However, if you are buying something for your
- company that your business will depend on, you would probably choose
- differently.
-
- For your business, you might consider buying the most expensive
- solution exercising the theory that you get what you pay for. However,
- once you've really studied the question, the right choice might well
- turn out to be a mid-range system from a stable, nationally recognized
- provider.
-
- There are some low cost IP service suppliers who claim to be just as
- good as the others, but may not be in business next year to prove it.
- Conversely, there are other suppliers who will attempt to justify
- providing the same level of services as their competitors, at many
- times the price.
-
- This guide suggests a set of questions to pose and evaluation criteria
- against which you can compare and contrast the different Internet
- service companies you have to choose from. In this exciting but still
- maturing market, the lure of Internet connectivity and Enterprise Wide
- Area Network outsourcing will require many companies to evaluate
- service providers within the next couple of years. The intent of this
- guide is to stimulate your thinking on the subject while challenging
- you to challenge your provider!
-
-
- Selection Criteria for Choosing Internet Service Providers
-
-
- Network Topology
-
- Network topology is one of the most important criteria to consider when
- choosing a provider. Looking at the network topology can help you
- understand how vulnerable the network is to outages, how much capacity
- is available when the network is loaded more heavily than usual and
- most importantly, how well the provider understands network
- engineering.
-
- Any competent provider should be happy to show you their network
- topology. It's a good way for them to demonstrate how well they
- understand their business.
-
- Look closely at what they show you. Some providers will give you a
- virtual backbone map. Virtual networks are meaningless. Your data
- does not travel on a virtual network -- it travels on a physical
- network. A virtual network map is merely a representation of all the
- theoretical paths that could be implemented by the supplier's virtual
- circuit switching equipment and is an attempt to side step the issue of
- physical capability. Your supplier needs to understand the physical
- network to understand what is important for serving their customers. If
- they tell you that the physical topology is unimportant, they either
- don't understand how to engineer a network or they are trying to
- disguise something. Remember, there is nothing inherently wrong with
- using frame relay, ATM, or other technologies that use virtual circuits
- as part of the backbone. However, your provider must understand the
- physical topology on top of which their virtual (logical) network is
- running.
-
-
- Network Link Speeds
-
- Now that we're evaluating the physical topology, let's look closely at
- the speeds of the backbone links. If they won't show you the speeds,
- then they're really hiding something. The first thing to understand is
- that your network connection can only be as fast as the slowest link in
- the path.
-
- It doesn't matter if you are connected to a T-3 node if there is a 56
- Kbps link between you and your destination. This is like hooking a
- half-inch garden hose to a fire hydrant. The limit is the garden hose,
- not how much water the hydrant can put out!
-
- Next, ask if the topology you are being shown is operational now. Some
- providers like to show links that are not operational as part of their
- backbone infrastructure. Some even go as far as to label the planned
- links with solid lines and the operational links with dashed lines!
- You're in for a big surprise if you don't notice this switch!
- Similarly, don't confuse the press release about a new high speed
- network link with that link actually being operational.
-
-
- External Network Links
-
- Now look at the external links of your candidate's backbone. Do they
- have a single connection to the rest of the world, e.g., via NSFNET?
- This is a potential single point of failure. Look for multiple, direct
- connections to other network providers. The more of these connections
- the better. This shows that the provider is concerned about external
- connectivity and does not want to be dependent on some third party for
- interconnection. If they have a single connection to the outside world,
- ask them how often it fails and how long they usually are isolated. If
- they can't give you these statistics, are they managing their network
- well enough to manage yours?
-
- Check to see if they have their own national backbone or if they rely
- on NSFNET for national connectivity. If they rely on NSFNET for
- connectivity, ask them what their plans are for national connectivity
- when the free NSFNET backbone goes away in April 1994. Now ask yourself
- if you have enough confidence in their plan to risk your connectivity
- to the rest of the world.
-
-
- High Speed Backbone
-
- If they claim to have a high speed backbone, check to see if it is that
- speed now or if it is just "planned." Some providers claim to have a
- T-3 (45 Mbps) backbone, but if pushed, will admit that what they really
- mean is "T-3 capable." A 2400 bps dial-up modem is also T-3 capable
- because tomorrow it is capable of being replaced with T-3. If they are
- misleading you about something as fundamental as their network
- capacity, what else are they trying to sneak past you?
-
- The next thing to ask yourself about high speed backbones is if you can
- actually connect to it for a reasonable cost. All service providers
- require you to buy the local loop segment from your facility to their
- closest Point Of (service) Presence or POP. You will have to buy this
- directly or indirectly from one of the telephone companies serving your
- local area. Some providers offer their service in such a way that the
- local loop cost is greater than their fee to provide you with the
- service in the first place. Think of the hose analogy again. If you're
- limited by the local loop speed because the price of a high speed loop
- is not cost effective, then how useful is a high speed backbone?
-
- Many providers will claim some impressive number of POPs. Find out what
- constitutes a POP by their definition. Some providers claim a POP
- anywhere they deliver service. Find out if many of their "POPs" are
- single customers at the tail end of low speed lines or if those POPs
- house high end routers linked by physically redundant high speed
- connections. Network POPs should be designed to scale with additional
- customers who, themselves, have growing requirements.
-
-
- Technology
-
- The technology being used to operate the network is also critically
- important. Today, there is plenty of commercial quality router, switch,
- and modem technology available from companies whose business is to make
- that equipment. Any provider still relying on their own internally
- developed equipment is doing you a disservice. You deserve the benefits
- of leading edge, production technology, not aging hardware that has
- been contorted into a use never intended by its designers.
-
- Sometimes a provider can have a bad case of "Not Invented Here"
- syndrome. This is a sure sign of long term problems. Remember, you are
- buying a service. The provider of this service should be using the best
- available technology to deliver this service. They should not use the
- service as an excuse to use surplus equipment and technology. The
- recent popularity of Internet connectivity has some strange bedfellows
- offering connectivity services. Again, ask yourself who you think has
- the better incentive to make a network connection work and keep
- working: the researcher who gets paid regardless of whether it actually
- works or the commercial supplier who only gets paid if it's working?
-
-
- Build or Buy?
-
- Another worrisome syndrome to watch out for is the "Control Freak."
- Some providers claim that they need to run even the lowest layers of
- their network to deliver quality service. This is simply not true. The
- truth of the matter is all Internet service providers rely on one or
- more telephone companies to assemble "their" network. The only way for
- any company to build "their own network" is to physically dig their own
- trenches and lay their own fiber into the ground.
-
- The only real question is at which physical link or transport level
- your potential service provider buys from the much larger phone
- companies. If the lower level infrastructure and service (such as T-1,
- T-3, Frame Relay or ATM) needed to support an Internet service
- provider's value added service is offered by a phone company, it's not
- cost effective or in the best interest of the provider's customers for
- the provider to even think about building and operating it. The
- provider simply can not match the economy of scale that comes with
- being a phone company. If your provider has chosen to build something
- when they could have bought a more reliable service more cheaply, why
- should you have to pay for their misplaced priorities? (If they can do
- it better and cheaper than the phone companies, why aren't the phone
- companies buying it from them?) The job of an Internet service provider
- is to manage and maintain your IP/OSI level connectivity. Look for
- strong relationships and partnerships between your Internet service
- provider and the nation's host of Alternative (Bypass), Local (RBOC),
- and Long Distance (IXC) carriers.
-
-
- Technical Staff
-
- Probably the most important aspect to consider when choosing a provider
- is the quality of their technical staff. The technical staff are the
- ones who will get your connection running to begin with and then keep
- it and the network running in the future.
-
- Check the experience of their staff in TCP/IP data networking. They
- should have several people who have been running TCP/IP data networks
- for close to 10 years. The average experience is also relevant, as it's
- likely that you won't usually deal with their most senior people.
- However, it's reassuring to know that the very senior people are
- available if you need them. Make sure that their "technical" staff
- consists of people who are experienced with TCP/IP and not of people
- whose previous assignment was "networking related" and have now been
- assigned to this new project.
-
- Make sure the provider has adequate staffing to cover the usual
- situations. If they send people to Interop for a week, how many people
- are back at the office running things and how skilled are they? If they
- only have a few technical people and they all go to shows, then what
- happens if your network connection breaks while they are gone for a
- week? (Be suspicious if they say they can handle it by dialing back
- in...)
-
- Find out what their technical staff turnover is. If people are leaving,
- find out why and who is left to keep your connection operational. Many
- suppliers of service have single points of failure in their staff
- capacity as well.
-
-
- Network Operations Center
-
- Check out their network operations center ("NOC"). It should be staffed
- by at least one person always. This includes nights, weekends,
- holidays, and during important sporting events. If they are quick to
- claim "7x24" operations, you might ask them what they provide the other
- 358 days of the year. An amazing number of providers claiming 7x24
- operations really mean that someone will answer the phone all the time,
- not that they will have someone capable of dealing with your problem.
- An answering service or beeper number is no substitute for a trained
- network engineer. Insist on one being always available and not just on
- call, as you can never tell when your connection will fail and what
- critical project it will have an impact on.
-
- Ask how the NOC is staffed. While it is normal to have only junior
- people on duty at odd hours of the night, it is critical that senior
- personnel be on site at least 8 AM-8 PM Eastern time, Monday through
- Friday. If your connection fails during normal business hours, you
- deserve to have very senior people immediately available to work on
- it.
-
-
- Organization
-
- Find out how long the company has been in the IP business. Determine if
- they are going to be in business for the long run. Maybe that deal is a
- bit too good to be true for a good reason. Quality networks are not
- built on a shoestring budget. The pricing may look attractive now, but
- the passage of time often reveals hidden costs and price increases, the
- greatest of which can be having to switch providers.
-
- Ask about their financial stability. While you don't need to see copies
- of their audited financial statements, you should at least be
- comfortable that they have a positive cash flow and are going to be in
- business next month to provide your connectivity. Determine if they
- have one or two major accounts that provide a disproportionate amount
- of revenue and what impact losing those accounts would have on their
- ability to maintain your quality of service.
-
- Are they an independent operating unit with its own staff and
- facilities or are they run out of the back door of a larger
- organization that doesn't know they exist? How critical do you think
- having the support of the parent organization is to their long term
- viability?
-
-
- "Non-Profit"
-
- At this stage of the market's development, some providers are operating
- from behind questionable non-profit cloaks. Some may be subjecting
- their sponsoring organizations to questionable legal and/or tax risks
- by selling commercial services in competition with for-profit
- corporations. The IRS requires that non-profits keep track of all
- revenue that is unrelated to their non-profit charter and pay the tax
- on it just like a for-profit corporation. Why should you care about
- your provider's tax troubles? It's all about selecting a provider that
- can supply you with the highest quality, best price performing,
- reliable Internet and Enterprise WAN network services. Legal or tax
- problems can provide a major "distraction" to the provider. As these
- services become more and more an integral component of your successful
- business, your choice is more critical and all dimensions of your
- supplier are integral to your decision. There will be a shake out in
- the Internet service business and only the strong will survive.
-
- Is the company rapidly growing and expanding or is it a stagnant
- anachronism and merely resting on its laurels and remembering the good
- old days when they were the only provider in the area? How long do you
- think they will survive in competition with healthy, growing
- companies?
-
- Is the group you're dealing with actually providing the network service
- or are they fronting, merely acting as a local aggregator for some
- larger entity? If so, what is the health of the larger provider and why
- should the larger provider give your connection the same attention that
- they are giving their directly connected customers?
-
- Does the provider have a straightforward internal business model or do
- they have a series of sub-contracts of sub-contracts and shell games
- with wholly owned subsidiaries? Why are they adding unnecessary levels
- of complication and expense, and why should you pay for it?
-
-
- Commercial Activity
-
- Is the provider a member of the Commercial Internet Exchange
- Association ("CIX")? This is a necessity if you are considering making
- commercial use of the Internet. If they are a member, see if they are
- really connected to the other members or have they just joined the
- association without interconnecting. Some groups advertise membership
- in the Association but have never interconnected. Some go as far as
- implying that they are connected to CIX members when they merely serve
- as a transit network for providers who are really members and are
- really interconnected. Don't let them confuse you. Insist on a straight
- answer.
-
- Does the provider require you to abide by an Appropriate Use Policy? Do
- you understand it? Is it ever enforced? Do you need to worry about it
- suddenly being enforced capriciously?
-
-
- Full Range of Services
-
- Does your provider have a full range of services, from low end to high
- end, or is it just filling a niche? If you need to increase or decrease
- your service level, will you need to switch providers?
-
- Does your provider offer true one stop shopping? Can they supply
- equipment, manuals, training, consulting, etc., as well as basic
- service? Can they provide connectivity throughout the country (and the
- rest of the world) or do they just serve a small region? Can they
- provide service in other countries through established partnerships
- with international suppliers and bill you on the same invoice as your
- domestic service?
-
-
- Customer Base
-
- Find out how many customers the provider has. Don't be mislead by the
- total number of customers the provider may brag about having. Some like
- to claim all of the individuals they have connected, while most others
- only count the organizations they have connected. The number of
- organizations willing to pay $1,000 per month for connectivity is a lot
- better indicator of the service quality than the number of individuals
- willing to pay $10.
-
-
- Comparison Shopping
-
- Do a price/benefit analysis. Some providers may appear to be priced
- less than others. Make sure you do an "apples to apples" comparison.
- Don't compare one provider's no frills service with another's full
- service offering. Don't be confused by the names of the products. What
- one provider thinks is Basic may be minimal or useless to you.
-
- Don't be afraid to ask for customer references and talk to them. See
- what issues current customers have. They will likely be similar to
- yours. If you get a reference, make sure there is no insider
- relationship with the provider such as an investor or a member of the
- board of directors.
-
- Find out where their new customers come from. The most interesting
- statistic is how many of their customers have switched from other
- providers!
-
-
- Conclusion
-
- The astonishing, worldwide growth of the Internet as a public access
- computer network has all kinds of new users, large and small,
- investigating the virtues of "getting on the Internet." Today, more and
- more companies are using the Internet to conduct their business,
- communicate with and support their customers, exchange electronic mail
- with hundreds of thousands of users, and seek and find valuable
- information leading to competitive advantage. This resource is
- indispensable once turned on. The choice of the service provider to be
- responsible for ensuring this vital business tool is the most important
- decision you will make when embarking on the Internet.
-
- Hopefully this white paper has provided assistance in examining some of
- the issues and raising some of the questions that will lead to a long
- and trusted relationship with your full service, professional Internet
- service provider.
