Performance of label switched path dynamic provisioning in GMPLS networks

Summary:Given the fact that control channels in GMPLS/MPLS-TE networks use packet-based forwarding, and the processing of control messages may be subject to various factors, the provisioning delay of an LSP could be highly random. To bridge the gap between the variable performance and demanding application needs, it is imperative to measure and characterize the LSP provisioning performance. In this article, we introduce the ongoing activities in IETF on defining standardized metrics and measurement methodologies for GMPLS/MPLS-TE performance. We also present our experiences in testing a number of GMPLS networks. The results can be seen as a sketch of performances of current state-of-the-art GMPLS implementations. We further point out possible future work in this area.
