Network performance management is an important task that should not be discounted by any company, large or small. Consumers are now requiring quick response time from companies and producers to fulfill their demands. For companies to remain competitive, it has become imperative that their lines of communication between the consumers and the workers inside the organization remain open and that bottlenecks become an extremely rare occurrence.
Network performance management is the measurement, modeling, planning, and optimization of networks, so that it is fast, reliable, and can handle the capacity required by each application while operating under budgetary constraints. Network performance management is measured using certain factors.
Latency is the length of time it takes for a packet of information to travel from one part of the network to another. Packet loss is the amount of data lost during transfer. Retransmission is the resending of data packets. There are two delays that happen during retransmission. The first delay is resending the data once the network realizes the packet loss. The second delay is to check whether the data resent is correct before sending it to another part of the network. Throughput is the maximum amount of traffic a network can carry.
Network performance management is part of a network manager’s job. Performance management measures network performance with per-port metrics, how much data goes through a port, or end-user metrics, the time it takes for an application to load on a user’s unit. Forensic analysis is the location of retransmissions or protocol negations using sniffers. Capacity planning is the usage of tools to see the effect of new applications on network performance. Load generation is the simulation of increasing traffic to the network to locate its breaking point. These are the tasks that network managers do on behalf of network performance management.
