IP over all-optical networks-issues

IP over optical is being envisioned as one of the most attractive architectures for the new Internet. There have been various proposals in IETF and other international standards organizations regarding the interaction of IP routers and optical core networks. This paper describes the architectural alternatives for the integration of IP and DWDM networks using Multiprotocol Lambda Switching (MPLambdaS). The paper also addresses the issues of routing, signaling, control and survivability in an all-optical network.
