Fast, secure call setup in CORONET multiple carrier domain networks

The Core Optical Networks (CORONET) program addresses the development of architectures, protocols, and network control and management to support the future advanced requirements of both commercial and government networks, with a focus on highly dynamic and highly resilient multi-terabit core networks. A key innovation of CORONET is the three-way handshake (3WHS) protocol for fast setup of optical connections in support of wavelength services in a single domain. Our initial 3WHS description was based on a single-carrier network. We have extended the 3WHS to networks partitioned into multiple carrier domains for which domain confidentiality must be preserved. We present analysis and simulation results demonstrating the performance of 3WHS in the multiple carrier domain scenario. The protocol has been shown to support approximately 30% more traffic by probing multiple intradomain paths in our simulated three-carrier example.
