    摘要: A technique is disclosed that evaluates a network path between (i) a first node in a first subnetwork of endpoint nodes, such as IP phones, and (ii) a second node in a second subnetwork. A “ricochet” node in the network path evaluates the path by probing one or both subnetworks, where the ricochet node acts as relay for traffic packets being transmitted between the two subnetworks. A given relay has only to probe a single, representative node within a subnetwork at any given time in order to obtain performance data that is representative of the subnetwork overall. By probing the representative node, the relay is able to acquire an assessment of network conditions that is valid for the path between the relay and any endpoint in the subnetwork. As a result, the disclosed technique reduces the probing overhead when many endpoint nodes on a given subnetwork are simultaneously active and experiencing adverse network conditions.

    摘要: A technique that seeks to direct and re-direct streams of packets through a packet network without adversely affecting the quality of service of existing streams is disclosed. In accordance with the illustrative embodiment of the present invention, streams of packets that are directed and re-directed through a packet network are initially put on probation. During the probation period, a quality-of-service measure for the stream is compared with a threshold whose value is initially high and decreases with time. This has the advantageous affect of noticing problems quickly so that they can be remediated quickly.

    摘要: A method is disclosed for conducting a search in which measurements of a time-varying property are made and updated during the search, and in which the measurements might be uncertain. In accordance with the illustrative embodiment, one or more search algorithm parameters (e.g., the maximum branching factor of a search tree, a depth cutoff for a search tree, a time cutoff, a threshold, etc.) are adjusted dynamically during the search based on at least one of: the degree of uncertainty of the measurements, the variability of measurements over time (e.g., standard deviation, etc.), and the fraction of members whose measurement is better than a threshold. In addition, the illustrative embodiment enables the search space to be pruned based on these criteria.

    摘要: An apparatus and method are disclosed that enable a first telecommunications endpoint to ensure that a second endpoint is receiving the first endpoint's packet stream transmissions with a satisfactory waveform quality. When the second endpoint receives the packet stream, it decodes the media waveform from the stream, encodes the waveform back into a second packet stream, and transmits some or all of the packets in the second stream back to the first endpoint. The first endpoint then decodes the received waveform in the second stream and compares it to the original waveform transmitted to the second endpoint. Based on the comparison, the first endpoint adjusts the value of a quality indication, and provides the quality indication to its user and to the second endpoint. Advantageously, the user at the second endpoint is able to determine whether the received waveform is, in fact, close enough to the waveform that the first endpoint's user intended to be received and understood.

    摘要: A method and an apparatus are disclosed that provide a privilege-granting technique for enabling a service-providing domain to grant a privilege to a requesting user in a service-requesting domain. A request handler in the service-providing domain, which comprises one or more service-associated resources, receives a user request to use a service and requests a token from a privilege-granting server, in accordance with the illustrative embodiment of the present invention. Upon receiving the token that specifies a granted privilege from the privilege-granting server, the request handler extends the privilege to the requesting user. Alternatively, the request handler can request a plurality of tokens in advance from the privilege-granting server; after receiving the tokens, the request handler extends a privilege to each requesting user as the handler receives requests to use one or more services.

    摘要: The present disclosure is based on a multi-core or multi-processor virtualized environment that comprises both time-sensitive and non-time-sensitive tasks. The present disclosure describes techniques that use a plurality of criteria to choose a processing resource that is to execute tasks. The present disclosure further describes techniques to re-schedule queued tasks from one processing resource to another processing resource, based on a number of criteria. Through load balancing techniques, the present invention both (i) favors the processing of soft real-time tasks arising from media servers and applications, and (ii) prevents “starvation” of the non-real-time general computing applications that co-exist with the media applications in a virtualized environment. These techniques, in the aggregate, favor the processing of soft real-time tasks while also reserving resources for non-real-time tasks. These techniques manage multiple processing resources to balance the competing demands of soft real-time tasks and of non-real-time tasks.
