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. The funding support of NIST ATP contract 70NANB8H4018 is gratefully acknowledged.
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)
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)

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)
Although all-optical transport may be the ideal, some OEO conversions will likely be necessary to control signal impairments. The placement of OEO conversions in optical networks affects critical design targets such as degree of transparency, cost, and robustness vis-à-vis demand forecast uncertainties. We explore two different impairment-aware OEO(More)
