IT299 Unit 8 Project
Discuss Network Topology
Network topology refers to the physical layout of a network. The chosen layout directly impacts how each node on a given network communicates with another. There are multiple types of topologies that can be used based on the need of the project. The ultimate goal is to provide multiple lines of data communication which will increase fault tolerance on the network and reduce or eliminate a complete disruption of service. A mesh topology offers the most effective fault tolerance over other methods and can be deployed in a full or partial configuration. In cases where cost is a factor, a partial-mesh can be used. In a partial-mesh, only critical WAN links are interconnected. This allows for efficient communication of critical data flows and a reasonable path for other communications to follow. Users would not likely notice an impact unless locations are significantly separated by long distances, such as an office on the opposite end of a continent. A full-mesh is significantly more integrated in that all locations are directly connected to one another. While this requires more dedicated data circuits, it is highly efficient and fault tolerant. A full-mesh is most sensible for large businesses that require the highest degree of redundancy. In the deployment of the Bench Fitness upgrade, we will utilize a partial-mesh topology. Although Bench Fitness has several locations, the nature of their business does not require an investment in multiple dedicated circuits. A dedicated T1 between server locations will allow dedicated communication between the Server 1 and Server 2 locations for server replication. Each Server location will require a CSU/DSU, router, and switch to accommodate the circuit provisioning. Other locations will utilize commercial grade internet services from the local cable provider. Reference the following drawings for a visual concept of the WAN layout as well as the circuit connectivity connections at
