| Summary: | As a basis for planning integrated QoS-enabled IP networks, proper evaluation of link capacities is needed to provide the desired level of quality for all supported classes in the network. As traffic characteristics and requirements of these classes are quite different, various dimensioning schemes are required, each estimating the share of capacity needed for its corresponding class. In S. Sharafeddine et al. (July 2003), a dimensioning method has been proposed to provide almost guaranteed quality of service for real-time traffic classes. While this method is applied for dimensioning single links, we propose in this work an appropriate extension that enables end-to-end capacity allocation. Moreover, we realize the given capacity planning problem in a dimensioning tool that supports different traffic classes belonging to the two broad categories, namely stream and elastic traffic. For this purpose, per-hop mapping of end-to-end QoS constraints is handled and a generic layered architecture is proposed and implemented. |
