Question

What are some of the performance factors and goals that are traded-off, one against the other, in the design of a network? Why should there be trade-offs? Shouldn’t a client be able to “have it all”?

Answer 1

Answer:-

What are some of the performance factors and goals that are traded-off, one against the other, in the design of a network:-

the scalability of the existing network must be determined in order to calculate the required steps that must be followed to perform the additional design work. It is important that any design being put together have some level of scalability and be able to expand to the future requirements of the company. Along with scalability is the importance of a design’s modularity. When the network is put together using a modular approach, implementation, operations, and troubleshooting can be considerably easier. Cisco offers its modular solution inside their SAFE offering.

The availability requirements of the proposed network must also be addressed. For example, is it important for the network to have a near perfect up time? Along with figuring in the availability requirements of the proposed network is designing a disaster recovery plan; it is during those unexpected times when a plan can make or break a company. Another part that goes hand in hand with the availability requirements is the calculation of the performance requirements of the proposed network.

There are a number of performance calculations that must be completed in order to correctly propose the best solution, these include:

• Bandwidth requirements
• Delay/Response time requirements
• Jitter requirements
• Packet Loss requirements (goes with availability)

In the modern technical world, the security requirements of the proposed network are also of the utmost importance. The breach of security of any company can be catastrophic for a number of different reasons; it is best that all the security requirements of a new network be addressed early in order to account for the different potential security scenarios. As the steps required for the security of a new design can be complex, a thorough review will not be completed in this article.

The manageability requirements of the proposed network can also be easily overlooked. While it may be obvious that the elements within a network be manageable, it is also important to consider how the management of these devices will work. For example, what would happen if a failure occurred within the network? Another aspect to consider is how the manageability options of the current and future equipment could be used to improve other aspects of the network including performance, troubleshooting responsiveness, and day-to-day operations.

Why should there be trade-offs? Shouldn’t a client be able to “have it all”?:-

Have you ever had to make a decision about spending your money today versus tomorrow? For example, you might ask yourself, 'Should I go out to dinner tonight, or would I rather save my money so I can go to the movies tomorrow?' You probably make decisions like this several times a day without even realizing it. Since your resources - such as time and money - are limited, you must choose how to best allocate them by making some trade-offs. Let's learn a little more about trade-offs and why understanding this concept will help you make better decisions about your time and money.

Most of us don't have so much money that we are in a position to buy everything we desire. We must put thought into every purchase and how it affects our bank account. We also must think about what type of satisfaction that purchase will give us. As a result, to get one thing that we like, we usually have to give up another thing that we also may like. Making decisions requires trading off one item against another.

In economics, the term trade-off is often expressed as an opportunity cost A trade-off involves a sacrifice that must be made to get a certain product or experience. A person gives up the opportunity to buy 'good B,' because they want to buy 'good A' instead. For a person going to a baseball game, their economic trade-off is the money and time spent at the ballpark, as compared to the alternative of watching the game at home and saving their money, plus the time spent driving to the ball game.

Trade-Off Examples

Going out on Friday night could involve several economic trade-offs. Let's say you really want to go to the bar with your friends. You will likely spend $40 that evening and get home at 1 AM. The first trade-off might be the four hours you
