摘要： Systems and methods for efficiently provisioning and assuring Quality of Service (QoS) between user networks communicating over a DiffServ-enabled network, with QoS management transparency to SIP user agents. The system comprises user networks communicating via a core network, each user network having a source and destination SIP user agent respectively, a SIP proxy server between the source SIP user agent and destination SIP user agent, a Bandwidth Manager to provision a pipe between the source user network and the destination user network, wherein the pipe has a specified bandwidth, and a QoS Agent for accepting and/or rejecting a SIP session based on availability of bandwidth in the pipe; wherein the SIP proxy server is configured to forward an incoming SIP request to the QoS Agent. The method comprises provisioning a pipe between the SIP user agents or their respective user networks, and allowing/rejecting incoming SIP sessions based on the available bandwidth in the pipe.

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： 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.
