Controlling Link Congestion on Complex Network

We studied the impact of bandwidth utilization factor on converged network of Zain Contact Centre which is a complex network environment in Nigeria. Some congestion control techniques were reviewed. Experiments were carried out on the real network, a legacy network and an integrated converged network considering the same number of users. The corresponding packets were compared. As a result, higher throughput and minimal packet loss were achieved at lower bandwidth utilization and better than what was obtained at higher utilization using the same parameters
