Paper Abstract

Carriers and service providers are rushing to provide Ethernet-based virtual private network services in metro area network (MAN) as the most cost effective way to address the needs of the enterprise network market. To address the fast recovery from any signal failure issue in the Metro Ethernet, we propose a metro Ethernet architecture based on multiple Enhanced Self-protected Spanning Trees (ESST). The recovery mechanism, named Birthday-based Link Replacing Mechanism (BLRM), in this architecture is able to transform a self-protected spanning tree into another spanning tree after any signal link or node failure. Simulation result demonstrates the effectiveness of the BLRM in achieving fast recovery.
