摘要： A method and system to identify an overload state in a remote network device within a communications network in which a local network device can send at least one message to the remote network device. The method comprises detecting at least one message transmission timeout for the message sent from the local network device to the remote network device, the message transmission timeout corresponding to a retransmission of the message from the local network device to the remote network device. The number of message transmission timeouts for the message or several messages is counted, with the method further comprising comparing the number of message transmission timeouts to a predetermined timeout threshold so that an overload state for the remote network device can be inferred when the number of message transmission timeouts exceeds the predetermined timeout threshold.

摘要： In an example embodiment a method is provided which comprises initiating at an offerer endpoint an offer message in Session Description Protocol (SDP) format. Included in the offer message is an indication of a plurality of potential configurations which the offerer endpoint is capable of supporting. The offer message is sent to an answerer endpoint to allow capability negotiation between the offerer endpoint and the answerer endpoint in a manner that is backwards compatible with existing endpoints. In an example embodiment, the indication of the plurality of potential configurations comprises assigning a new attribute or value to an existing type of SDP identifier.

摘要： In one embodiment, a method is illustrated as including receiving a data packet at a network device, and upshifting a Quality of Service (QoS) reservation, wherein the upshifting is based upon an observed increase type selected from the group consisting of an observed increase in network traffic, data packet size, and data packet frequency. In a further embodiment, a network device is illustrated as possessing a receiver to receive data packets, and an upshifter to upshift a Quality of Service (QoS) reservation, wherein the upshifter observes an increase type selected from the group consisting of an observed increase in network traffic, data packet size, and data packet frequency.

摘要： A system for enforcing policy in a communication network includes a policy server which is operable to receive a request to invoke an application, receive a policy profile for a network user, and decide a proper allocation of network users based on the policy profile, the application, and available network resources. The policy server is further operable to communicate with a non-SIP application. The system also includes a network resource manager operably associated with the policy server and operable to monitor available network in the resources in the communication network. In addition, the network resource manager is functional to allocate network resource amongst a plurality of network users. The system also contains an application control point which is operably associated with the policy server and operable to communicate with a SIP application. The system is operable to use policy peering between the home and visited network to enable user-specific policies to be enforced while roaming.

摘要： In one embodiment, an endpoint sends messages containing Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (NATs) (STUN) requests to traceroute a path to the remote endpoint. The traceroute may be completed through security devices such as NATs and firewalls. Receipt of a STUN response from the remote endpoint signals that one of the traceroute packets reached the remote endpoint whereas the other traceroute packets have elicited error responses from intermediary, on-path routers, allowing these routers to be identified.
