Re: [RPRWG] MAC Question


I guess the answer is that the group is still debating this issue. Some
vendors prefer to have a largish transit buffer where transit frames
are stored. Others are proposing "cut through"  transit functionality.

I personally feel that latency will be larger in the first approach.

On another note I do not believe that the similarity with 802.5 is
on the lines of claiming a token etc. etc. The MAC mechanism
is going to be different.

Hope this helps.
