Abstract

The thrust of this study is to construct an MPLS test-bed using open hardware and software and later use this test-bed for experimenting various traffic engineering options available with MPLS. We have constructed a test-bed using Pentium PCs and Linux and used this test-bed to try a well-known MPLS traffic engineering feature of separating flows into multiple trunks. The purpose of this separation is to experimentally assess the quality of service benefits we can expect from MPLS networks. We experiment with a hierarchical separation structure where the first level of separation is based on the transport layer used (TCP or UDP). This high level separation prevents UDP from unfairly grabbing the available bandwidth from TCP applications. Since different applications using TCP have different needs, e.g., some might want high bandwidth while others are more sensitive to packet delay, the second level of separation is based on application type. The results from our open experimental test-bed confirms the intuitive results by demonstrating better QoS with the flow separation in the MPLS core.
