Buffer and bandwidth allocation for diffserv classes

摘要

This papaer proposes an optimal method for allocating buffer and bandwidth to different classes of a forwarding engine within a Differentiated Services domain in the Internet. The optimality criterion is based on the cost of the buffer and bandwidth. Based on this criterion, the best class that matches a certain traffic with a certain statistical characteristics and the maximum packet delay corresponding to this class is found. The results are general and can be applied to other networks such as ATM.
