    摘要： Systems and methods for determining lost packets for real-time transport protocol (RTP) data flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor. The processor is configured by the software to perform the steps of determining a sequence number of a received RTP data packet within said RTP data flow, storing said determined sequence number, calculating whether said determined sequence number sequentially falls within a predetermined numerical order, and if said sequence number of said received RTP data packet does not sequentially fall within said numerical order, storing said sequence number as a missed RTP data packet.

    摘要： Methods and systems for controlling access to a host processor is disclosed. One exemplary method comprises the steps of receiving a plurality of signaling packets and controlling access to a host processor, via a first and a second path, for at least a portion of the packets in accordance with a bandwidth limit for the respective path. An exemplary system comprises: a host processor; and a traffic manager coupled to the host processor via a first path and a second path. The traffic manager is configured to communicate at least a portion of the packets to the host processor via a selected one of the paths. The traffic manager is further configured to regulate traffic along the first path such that the bandwidth limit of the first path is respected, and to regulate traffic along the second path such that the bandwidth limit of the second path is respected.

    摘要： A system and method for providing statistics gathering within a packet network is disclosed. The system comprises a network processor, a traffic manager, a host processor, and a field programmable gate array. The network processor adds a header to received multimedia packets and the traffic manager measures and enforces multimedia flow rates. The host processor performs multimedia flow quality measurement services on a per flow basis, wherein the multimedia flow quality measurement services comprise maintaining current statistics for multimedia flows within the network processor including aggregate and minimum/maximum statistics for the multimedia flow. The field programmable gate array (FPGA) copies a received multimedia packet or a portion of the received multimedia packet, wherein the copy is utilized by the FPGA to perform statistics gathering via use of a latency engine, a lost packet calculation engine, a real-time transport control protocol packet jitter engine and a real-time transport protocol packet jitter engine.
