Abstract

In Multi-Protocol Label Switched (MPLS) networks, the number of traffic engineered tunnels or Label Switched Paths (LSPs) setup has an impact on network state maintenance, administration and scalability. In today\´s MPLS standards, for the purpose of path computation and signaling, multiple traffic classes carried together of a given service of a customer are treated individually. This work looks into MPLS paths which allow for the accommodation of up to eight distinct traffic classes per LSP. A comparison is made that shows scenarios in which such traffic class aggregation or "bundling" can provide a significant reduction in the number of paths in the network.
