Re: [RPRWG] MAC Question


This is a design choice and is currently the subject of much
debate within RPR.  My view is that the latency/jitter issues
will be there in either a store & fwd or cut-through design.

It is simply a question of where you introduce the jitter,
on the ingress path or the transit path.

In the next couple of meetings, I'm sure we will be seeing
some concrete results to compare the two approaches.
