Dynamic Path Scheduling Through Extensions to Generalized Multiprotocol Label Switching (GMPLS)

A growing requirement of government laboratories and operational networks is the ability to support scheduled access to high-bandwidth networking resources, in order to guarantee the lowest possible latency supporting e-science and grid applications. This project will develop a distributed scheduling solution that meets these requirements. In particular, a distributed software solution will be developed for a prototype optical switch that can perform dynamic scheduling of bandwidth for e-science and grid applications in an optical network. Phase I will extend an optical-control-protocol suite to suport time-dependent objects needed for scheduling. Existing scheduling algorithms will be used, or modified if applicable, for a time-dependent path computation in the Phase II prototype software. Using existing hardware, these capabilities will be demonstrated in the UltraScience Network at the end of Phase II. Commercial Applications And Other Benefits as described by the Applicant: The technology should provide improved time-share network resources for triple-play, HDTV/IPTV, telemedicine, collaborative research, and peer-to-peer communications. Commercial network operators (telecom and cable) would be better able to leverage their network resources to lower their operations costs. Savings could be passed on to consumers, enabling higher subscriptions for fiber-to-home services. Government and commercial customers should become more competitive and collaborative by improved access to high-performance networks.
