Abstract
A communications network is evaluated by selectively sending and receiving a plurality of network evaluation signals through the network. Responsive to these evaluation signals, selective network evaluation parameters are determined and stored. Responsive to these parameters, the response time and throughput characteristics of the network are determined by means of algebraic and queuing theory derivations. Network response time analysis determines the apparent bandwidth, utilization, internal message size, queue factor, and device latency. Throughput analysis defines, calculates, and uses hop count, duplex, throughput and multi-server factors. Service level and capacity planning provides comprehensive “what-if” network planning facilities, including calculation of the change in network traffic before network response time service level is compromised; calculation of the additional file load capacity of the network; and determination of tuning recommendations for recommended window size for file transfer to fill remaining capacity.
