Dynamic configuration of label switched path

Abstract

This report deals with the analysis of dynamic configuration of label switched paths (LSPs) with help of the project: mpls-linux. This analysis was made over a virtual testbed which was created with Netkit and User-Mode Linux (UML) under Linux. Different scripts were developed in order to configure the LSPs and allow a datastream to switch from one LSP to another. This paper starts with explaining the main MultiProtocol Label Switching (MPLS) concepts. The reader that already masters these concepts may safely skip this chapter. Then, the virtual testbed is described as well as the underlying concepts of virtual machines. Afterwards, the use of an implementation of the Label Distribution Protocol (LDP) is described to create a LSP based on an IP-prefix FEC (i.e. destination-based FEC). In the following chapter, the explicit routing and dynamic rerouting of LSP is outlined. Finally, pointers to further research will be exposed.
