DiffServ is based on network nodes applying different forwarding treatments to packets whose IP headers are marked with different DiffServ Code Points (DSCPs). As a result, use of different DSCPs within a single traffic stream may cause transport protocol interactions (e.g., reordering). In addition, DSCP markings may be changed or removed between the traffic source and destination. This document covers the implications of these DiffServ aspects for real-time network communication, including RTCWEB.}, }
