摘要: Due to the fast increase of Internet traffic and enormous bandwidth potential all-optical transport networks based on wavelength division multiplexing, an IP-over-WDM network scenario is likely be widespread in future communication networks. At same time, IP are becoming more mission-critical. Hence, it paramount importance for able recover quickly from frequently occurring failures. This paper explains how multi-protocol label switching (both electrical optical) recovery mechanisms can important reach that goal. Moreover, a novel MPLS mechanism called topology-driven constrained-based rerouting presented. Different compared each other. Special attention hereby goes additional capacity required
