Introduction * The traditional network design process: follows a very structured systems analysis and design process similar to the used to build application system. 1. Meet users to identify needs and the app system planned for the network 2. Estimate the total amount of traffic on each part of the network 3. Circuits needed to support * Pros: works well for static or slowly evolving network * Cons: Expensive and time consuming * 3 forces: making the traditional design less appropriate * The underlying technology of the client and server computers, networking devices, and the circuit themselves is changing very rapidly * The growth in network traffic is immense * With such rapid growth, it is no longer possible to accurately predict network needs for most networks. * The balance of costs have changed * Staff members cost > Hardware cost. * The building-block network design process: network that use a few standard components throughout the network are cheaper in the long run than networks that use a variety of different components on different parts of the network * Goal: simpler design process and more easily to manage * 3 steps * Needs analysis * Baseline, geographic scope, app system, network user, needs categorization * Technology design * Clients and server, clients and devices * Cost assessment * Off the shelf, request for proposal * Needs Analysis * Goal: why the network is being built and what users and apps it will support * Goal: produce a logical network design; statement of the network elements needed to meet the needs of the org * Geographic scope: the first step in needs analysis is to break the network 1.
