Backbone Network Architectures for IP Optical Networking
15 August 2000
Novel service layer (IP/MPLS) and transport layer (SONET/SDH, WDM) network architectures are analyzed and compared for IP backbones, considering multiple parameters; network capacity, cost, restoration strategy, reconfigurability and accommodation of preemptable traffic. The results show the value of transport layer networking in multi-terabit IP backbones.
