TECHNIQUE FOR PERFORMING ANALYSIS OF AN RTP FLOW

Abstract:

A technique for performing segment-wise analysis of a Real-Time Transport Protocol, RTP, flow carried from a first User Equipment, UE, to a second UE via a mobile network is disclosed. The RTP flow is monitored by a plurality of probes in the mobile network, wherein each of the plurality of probes is configured to calculate at least one performance indicator indicative of a performance associated with the RTP flow observed between the first UE and the respective probe. A method implementation of the technique includes deriving at least one segment performance indicator for a segment of the RTP flow between a first probe of the plurality of probes and an endpoint of the segment by deducting the at least one performance indicator calculated by the first probe from at least one corresponding performance indicator associated with the endpoint.
