Executive Summary

In this paper, the authors introduced Modified Sized-based Queue Management as a dropping scheme that aims to fairly prioritize and allocate more service to VoIP traffic over bulk data like FTP as the former one usually has small packet size with less impact to the network congestion. In the same time, they want to guarantee that this prioritization is fair enough for both traffic types. On the other hand they explain the total link delay over the congestive link with the attempt to alleviate this congestion as much as possible at the by function of early congestion notification. Their M-SQM scheme has been evaluated with NS2 experiments to measure the packets received from both and total link-delay for different traffic.
