Translating Scalable Video Streams From Wide-Area to Access Networks

Tags:
tcp - ip

Overview Transmitting video over UDP has been considered advantageous because it allows for discarding of packets in favor of retransmissions, and sender-controlled timing. Using UDP has been criticized because it allows video streams to consume more than their fair share of bandwidth, which is typically associated with the back-off behavior of TCP. TCP-friendly algorithms are meant as a middle path. However, UDP delivery to end systems may still be prevented by firewalls or for other reasons, and TCP must be used. This in turn suffers from bandwidth fluctuations. Therefore, this paper investigates an architecture that separates the transfer of a video stream over long distances in a TCP-friendly transmission in the backbone and TCP transmission in access networks.

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
