Abstract

This paper evaluates the efficiency of set of modifications to the border gateway protocol (BGP) which aim at providing flexible traffic engineering (TE) across multiple GMPLS domains. A short overview and analysis of existing proposals for BGP-TE extensions is presented. Based on that, three modifications are proposed for support of multi-domain TE: an end-to-end path-specific TE attribute, a border node attribute and a behavioral modification of the protocol. Via analysis and extensive simulations we show that the proposed enhancements successfully improve the most significant BGP drawbacks and the label switched path (LSP) blocking probability in dynamic multi-domain GMPLS environments.
