IPTV delivery networks are likely to consist of a wireless access network and a wired path across a metro network. Downlink and uplink video streaming may take place. In this scenario, the paper compares two congestion controllers with UDP and broadband video streaming (BVS), the proposed single negative acknowledged packet retransmission. The results demonstrate that in this environment the congestion controllers (single- and multi-connection versions of TFRC) are unable to both reduce packet loss and overall delay, whereas BVS is sufficiently able to compensate for packet losses without overly increasing delay and without the overhead of application forward error correction. The paper exposes asymmetrical streaming behavior between uplink and downlink streaming and finds that for downlink streaming packet reordering by video frame type is sensible.
