Re: [802.3_NGEPON] Questions about fragmentation in EPON



Duane,

 

I do not know what these questions really mean, given that it is not clear WHERE the fragmentation is done layer-wise and how the mechanism works. As Glen said, without pictures showing what happens where, we are making a lot of assumptions, which is not helpful to consensus building …

Glen/Marek,

During the call today you both expressed concerns about fragmentation. Do the following two questions adequately capture your expressed concerns? If not please clarify.

1)      In a multi-lane mixed capability network (mix of 25G, 50G & 100G ONUs) how would fragmenting avoid loss of capacity due to gaps between bursts?

2)      In a multi-lane mixed capability network how could fragmenting allow an ONU that is bursting on X lanes expand its transmission to X+m (ex. go from 2 lane transmission to 4 lane transmission) smoothly?

Best Regards,

Duane
