There are different types and locations of network exist, including network in a home or home office to communicate through the Internet, to locate information, to place orders for merchandise, and to send message to friends. Whatever the reasons are, all these networks share common components. According to Network World, the most common network components are Personal Computer’s, interconnections, such as NICs, Networks media, and Connectors. Switches and Routers are also part of network components. When designing a network, couples of items are a must to have such fundamental goals, a drawing or diagram, The Hierarchical Network Design, IP addresses, routing protocols, Servers, and switches.
Good Network does not happen on its own. Accordance to SCTE website, “The network diagram uses common symbols to capture information related to the network for planning, reference, and troubleshooting purposes. The amount of information and the details of that information differ from organization to organization”(Introducing Network Design Concepts). To design a decent network these steps must be follow: Verify the business goals, determine the features and functions required to meet the needs identified in the previous step, perform ad network assessment, create a solution and acceptance test plan, and create a project plan.
In addition, fundamental Design Goals are also important. Fundamental Design Goals consist of scalability, availability, security, and manageability. Scalability on the word of SCTE websites is a “Scalable network designs can grow to include new user groups and remote sites and can support new applications without impacting the level of service delivered to existing users”(Introducing Network Design Concepts). Availability is “one that delivers consistent, reliable performance, 24 hours a day, 7 days a week”(Introducing Network Design Concepts). Security is “a feature that must be designed into the network, not added on after the network is complete. Planning the location of security devices, filters, and firewall features is critical to safeguarding network resources”(Introducing Network Design Concepts) and Manageability is “No matter how good the initial network design is, the available network staff must be able to manage and support the network. A network that is too complex or difficult to maintain cannot function effectively and efficiently”(Introducing Network Design Concepts). A network diagram is also an important factor when...
