Network Testing in a Testbed Simulator using Combinatorial Structures

This report covers one of the most demanding issues of network users i.e. network testing. Network testing in this study is about performance evaluation of networks, by putting traffic load gradually to determine the queuing delay for different traffics. Testing of such operations is becoming complex and necessary due to use of real time applications such as voice and video traffic, parallel to elastic data of ordinary applications over WAN links…
