Dimensioning Methods for IP Networks under End-to-End QoS Constraints

This paper considers the QoS design of packet–switching networks. We propose a packet network design and planning approach that considers the dynamics of packet networks, as well as the effect of protocols at the different layers of the Internet architecture on the e2e QoS experienced by end users. Subproblems are derived from a general design problem and a collection of heuristic algorithms are introduced for computing approximate solutions. We illustrate examples of network planning/dimensioning considering Virtual Private Networks (VPNs).
