Traffic Engineering of MPLS Backbone Networks in the Presence of Heterogeneous Streams

Heterogeneous streams (Due to issues such as disparate traffic characteristics of each stream, or competing customers' traffic) raise the issue of whether to multiplex (Some of) these streams. In an MPLS network, such multiplexing can be considered by putting different streams into a tunnel identified by a single Label Switched Path (LSP), assuming that the different LSPs are assigned a reserved share of the resources. This issue becomes even more important in the traffic engineering of a backbone network when a decision needs to be made on which streams to multiplex when there are constraints on tunneling and capacity along with routing requirements for tunnels.
