摘要： At least one substitute path is provided in place of a plurality of existing paths of a network to reallocate traffic carried by the plurality of existing paths. The total bandwidth needed to carry the traffic of the plurality of existing paths is determined. A proposed route is generated from the available links in the network. A portion of the bandwidth of a proposed route may be allocated to the needed bandwidth when the bandwidth of a proposed route is greater than or equal to the needed bandwidth. When the bandwidth of the proposed route is less than the needed bandwidth, at least one further route is generated, and the needed bandwidth is divided among the proposed route and the at least one further route such that a minimum number of further routes are generated.

摘要： A payload switching architecture for LEO satellite networks minimizes processing and storage requirements of payloads for deployment as small primary or secondary payloads, payloads perform only forwarding functions. Forwarding rules are provisioned in the payloads enabling them to reroute in case of failures or congestion without intervention from a ground station. Configuration rules are provisioned in the payloads enabling them to dynamically establish and remove interplane crosslinks without intervention from a ground station. The central network operations center on the ground computes forwarding rules and configuration rules for payloads and uploads the rules to the payloads.

摘要： A policy change management scheme for network resource management through dynamic policy adaptations especially suitable for DiffServ-enabled MPLS networks is presented. The scheme incorporates automated resource adaptation capabilities to assure QoS for user traffic and to promote resource utilization in DiffServ-enabled MPLS networks. A suite of resource management policies, an ordered set of methods for adjusting policies, and interfaces to a companion policy-based network management system are provided. The policies are periodically adjusted based on predictive bandwidth estimation algorithms ensuring optimal resource allocation to individual service classes and enabling adjustment of resources for handling current traffic and traffic expected for the near future. Resource allocations to individual service classes are adapted through policy changes when bandwidth utilization deviates from normal level or congestion exists in one or more service classes, allowing corrections to abnormal allocation of resources in incipient phases of congestion.

摘要： In future large-scale Emergency Response/Management (ER/EM) to terrorism and natural disasters, sharing the so-called common operational picture amongst dynamic task groups provides immediate advantages. In an ER/EM scenario, dissemination of the right data to the right person at the right time has a direct benefit. Timely and bandwidth efficient dissemination of sensor and Command and Control data remains a challenge. For example, dynamically changing mobile teams, information-needs profiling, information routing based upon information needs (not on IP address) are all complex issues. Accordingly, a protocol, called dissemination mesh, for constructing and reconfiguring network paths for disseminating information from sources to sinks, a software architecture for multi-domain wireless network information dissemination in the context of emergency response (resting above existing MANET protocols), supports needs-based dissemination, node mobility, rapidly changing groups (information sinks) and sensor networks (sources) is provided. The protocol includes: exploitation of Semantic Web and collaborative agent technologies, novel subscription-based information dissemination, intelligent networked information intermediaries, smart dissemination mesh forming and management. Together these technologies provide information dissemination management in the wireless setting. Application realms other than ER/EM can also be supported.
