A network for a business organization is its nervous system. Almost all the business activities executed on the network infrastructure. As an example, all the electronic communication such as emails and VoIP will collapse if the computer network fails. In addition to that, all the electronic content sharing between the computers will fail while there is no access to the Internet. There is evidence that such scenarios have taken place in the history of information technology due to the vulnerabilities in the computer network design.
Computer network design is one of the main steps in implementing a computer network. When a home computer network is considered, there is not much need for a sophisticated computer network design. But still, there should be some kind of a primary design in order get things working correctly. This small example alone enough to understand the importance of computer network design when it comes to business organizations.
There are many things to be considered when it comes to computer network design. First of all, it is the nature of the business and the networking requirements that matter when designing a computer network. If the organization is located in a large geographical area, such as a university, then the requirements for the networking will be quite high and there can be an added complexity as well. If the organization is scatters across the country and still require the locations to be connected through a private network, then the resources required for the proposed network will be high and the computer network design will be quite complex.
The network topology plays an important role when it comes to the computer network design. Based on the network requirements, the nature of the business, and the technology used in the business organization, the appropriate network topology should be selected. Once the network topology is finalized, the designers can carryout the task of computer network design.
In a good computer network design, the devices used are properly illustrated. This gives the organization a proper idea of what resources required and the possible cost involved in the implementation. In addition to that, the failover or the contingency plan is also an essential part of a computer network design. This part discusses the possible ways of network failures and the steps that need to be taken in order to maintain the business continuity. Sometimes disaster recovery is also included into the computer network design, but this is not an essential part of the design.
