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 summarize the DARPA CORONET program approach to bandwidth-on-demand, and implementation and demonstration of Cloud Computing applications in network testbeds. Recently, there has been major impetus for Bandwidth-on-Demand (BoD) in carrier networks, driven by the burgeoning demand for cloud computing services and a desire to reduce costs through bandwidth… (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 enhance the potential cost savings from optical network transparency by applying Connected Dominating Sets and impairment-aware routing, thus reducing the density of OEO nodes substantially below that obtained with more straightforward path improvement heuristics. The funding support of NIST ATP contract 70NANB8H4018 is gratefully acknowledged.
IP over optical network performance can be improved with dynamic bandwidth allocation, depending on the reallocation paradigm and the network topology. Under high connectivity, dynamic bandwidth allocation provides a notable boost to the network's traffic-carrying capacity.
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)
