1. According to Priscilla Oppenheimer, design requirements depend on multiple factors- one of them being the business requirements (Oppenheimer, 2010, p. 320). Although this assertion is made in the context of a fresh network design, most of the design goals together with business requirements and constraints remain valid when the objective is to upgrade the current network.
Design requirements include both the technologies and devices that will be implemented in the upgraded network infrastructure. These can be gathered by analyzing at least the following matters: topology changes, technical goals and QoS (quality of service) requirements. Each of these categories contains features that must be addressed only after the business requirements were properly identified....
