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.

Abstract: A measuring band for marking of centre to centre (C/C) distances, especially in connection with building frameworks, the measuring band at least on one side being provided with information, a number of lines (1, 3, 5) extending transverse to the longitudinal direction of the measuring band. The invention also relates to a method for the marking of centre to centre (C/C) distances. It is significant of the measuring band that adjacent lines (1, 3, 5) are located at a distance from each other of at least 30 cm, the distance between adjacent measuring indicias (1, 3, 5) is the same, and a marking symbol (X) is provided on the same side of each line (1, 3, 5).
