    摘要: An apparatus including a plurality of packet processors each included in one of a plurality of voice-over-internet-protocol (VoIP) network interfaces. Each of the plurality of packet processors is configured to cache a latest version of realtime transport control protocol (RTCP) report data by discarding an older version of the RTCP report data. The RTCP report data includes at least one of RTCP sender report data and RTCP receiver report data. The apparatus also includes a packet data switching matrix configured to switch packet data between ones of the plurality of VoIP network interfaces. A central processor of the apparatus is configured to generate a final session detail record upon the termination of a VoIP-session by selecting RTCP session-concluding report data from a plurality of RTCP final report data each cached by a corresponding one of the plurality of packet processors.

    摘要: A method of adaptive resource allocation in transmitting data is provided. In particular, the method of the present invention is applicable to scheduling bandwidths using a modified and dynamic weighted round robin process. The method includes the steps of allocating a resource to each of a plurality of data transmitting active connections, the plurality of active connections belonging to more than one class of service. Then the method determines a lender class of service for each active connection from which resources may be reallocated to the active connection, and periodically comparing the resource usage of an active connection to an upper threshold and a lower threshold. Borrowing action for resources from the lender class of service for the active connection is carried out in response to the current usage exceeding the upper threshold, and returning action for borrowed resources to the lender class of service from the active connection in response to the current usage being less than the lower threshold is carried out.
