Novel Node Structures for IP over WDM Networks

摘要

IP over WDM is being envisioned as one of the most attractive architectures for the next generation Internet. This paper introduces two novel backbone node structures for IP over WDM networks. These node structures can be used as improvement approaches to DPDP (default path and dedicated path) method. The flow classifiers, which are the main components of these node structures, and the performance metrics of these structures, are also discussed.
