Coloring VBR Streams Inside the DiffServ Domain
Video traffic is supposed to account for a large portion of future wired and wireless network traffic. The evaluation of different video coding standards for their effects on the network traffic, and the resulting requirements for networks have attracted great interest in the research community. Simultaneously, the numerous test and users' experiences proved that the limited quality of service (QoS) features available in both IPV4 and IPv6 cannot accommodate the various degrees of requirements needed by multimedia traffic and in particular, the video traffic. This paper investigates the influence of various packet markers on VBR video streams inside the DiffServ domain. Simulations based on NS-2 network simulator and Evalvid-RA framework and follow the IETF recommendations for video traffic shaping in the IP networks.
