  • Method for facilitating latency measurements using intermediate network devices between endpoint devices connected by a computer network
    Patent number: 7944840
    Abstract: Network latency measurements of RTP traffic are measured using an intermediate network device positioned between endpoints that do not necessarily support RTCP. During an active RTP stream between two endpoints, the intermediate device detects whether the endpoints are already providing their own RTCP packets and responding to RTCP packets from the other endpoint. If not, the intermediate device generates RTCP packets on behalf of the non-responsive or non-providing endpoint(s), acting as a proxy for the endpoint(s), so the packets appear to one endpoint as if they were generated by the other endpoint. Thus, if at least one endpoint supports RTCP, a single intermediate device is sufficient to generate the RTCP packets that allow the latency calculation to be performed.
