Multi-packet FEC Date: 2007-11-13 Authors: November 2007 November 2007 doc.: IEEE 802.11-07/2847r0 November 2007 Multi-packet FEC Date: 2007-11-13 Authors: Alex Ashley, NDS Ltd Alex Ashley, NDS Ltd

November 2007 doc.: IEEE 802.11-07/2847r0 November 2007 Abstract This presentation describes an example of an end-to-end flow of video content in which a forward error correction code is applied. Alex Ashley, NDS Ltd Alex Ashley, NDS Ltd

Example IPTV Deployment November 2007 Example IPTV Deployment Content flows from VOD servers to the home via the core network. This flow has to provide end-to-end QoS. VOD Servers Retransmissions outside the home disabled, to avoid overloading network. DSLAM Core Network DSL Modem Alex Ashley, NDS Ltd

November 2007 Multi-packet FEC A side-channel is added at the VOD server, which provides ‘n’ error correction data packets Ptotal = Pdata + Pprotection Receiver can create perfect picture with loss of any ‘n’ packets Alex Ashley, NDS Ltd

November 2007 Multi-packet FEC & 802.11 Over 802.11, all unicast traffic gets re-transmitted until positive ACK received Or MIB defined retry limit reached If an application level FEC is already in place, 802.11 could be more intelligent in its retries A STA could reduce its retries if it had knowledge of higher level recovery technique Alex Ashley, NDS Ltd
