This influences the actual real life problem a lot and in my understanding of 8B/10B coding, itīs designed not to lose sync over a single bit error so with a probability of bit error every few minutes, hitting two in close succession (in the window) is unlikely. Some time ago we did experiments implementing FEC at IP layer to make the multimedia which run over the network zero loss. While doing the experiment we recognized that the clustered loss we saw was caused by software issues in routers, not at any transmission devices. Using somewhat deeper interleaving of packets solved the issue with this application. PeteReceived on Thu Mar 11 2004 - 20:41:18 UTC
