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. CORONET encompasses a global network supporting a(More)
We present a method for impairment-aware routing in transparent networks that allows constraint dependencies and objectives minimizing regeneration cost. The method is guaranteed to identify impairment-feasible paths when they exist and uses transponder resources efficiently. © 2003 Optical Society of America OCIS codes: (060.4250) Networks; (060.4510)(More)
Planning and designing the next generation of IP router or switched broadband networks seems a daunting challenge considering the many complex, interacting factors affecting the performance and cost of such networks. Generally, this complexity implies that it may not even be clear what constitutes a “good” network design for a particular specification.(More)
The DARPA Core Optical Networks (CORONET) program envisions a highly dynamic network environment requiring fast provisioning and restoration for a wide variety of bandwidth-on-demand services in IP-over-optical networks. This paper builds on previously reported work on the development of fast provisioning and restoration protocols to meet CORONET(More)
We address the requirements and design of bandwidth on demand networks in the context of Grid services. Regardless of the deployment scenario for Grid services (e.g., commercial or research), there is a need for efficient use of network facilities and a need to meet the performance requirements of the Grid services users. We present quantitative analysis(More)
Despite advances in CAD tools, layout errors resulting in electrical shorts between complex nets continue to cause trouble in many VLSI design projects. Locating the geometrical features causing shorts is often the most vexing problem faced during the layout verification process. Although this problem is common and important, there seems to be no published(More)
A previous paper demonstrated that spacetime transformations consistent with the principle of relativity can be derived without assuming explicitly the constancy of the speed of light. Here we correct an error in the earlier paper while showing that this derivation can be done under weaker assumptions, in particular, without an implicit assumption of(More)
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(More)
