Abstract | |||||||||||||||
| This paper presents a tool for MPLS Traffic Engineering that allows for multi-hour dimensioning of networks supporting simultaneously peer-to-peer and client-server services. It is assumed that all LSPs to be routed and their attributes are known. The dimensioning problem is a combined capacity design and routing problem where the LSP sets are calculated in order to minimise the network operational costs. This problem is formulated as an integer programming problem, which is solved through an heuristic based on Lagrangean relaxation with sub-gradient optimisation. The network design tool, named PTPlan MPLS, includes a graphical interface for an easy introduction and edition of the network parameters. Results show that the tool can design large networks with good computational speed. I. | |||||||||||||||
