... layer 3 switches in the distribution layer. Fig1. example of how clients (PC's) are connected to a hub Gigabit campus switches offer users the chance to build an extremely high performance networks, high reliability and with the ability to make self-management implementations makes it easy to manage and maintain. A hierarchical design known, as Multilayer design will be the conceptual approach we shall take for the Middlesex University Network. A typical hierarchical network design includes three layers:> Core Layer> Distribution Layer> Access Layer Starting with the Core Layer, this is a high speed switching the backbone which is designed to switch packets with minimum latency. This layer is restricted to perform any packet or frame manipulation, e.g. processing access lists and filtering because as a result this would slow down the number of packets being switched. The core layer is a pure Layer 3 switched environment, which simply means that VLANS ...
