Re: [RE] CE applications (was: RE: [RE] Focus of discussions)



Michael, I think you are correct also. Additional forwarding hops requires
additional buffering.

The next question is, is this a practical consideration for the home where
we might assume a limited number of hops and relatively relaxed latency
requirements?

I think you are correct, Kevin, with one major concern: using strict
priority mechanisms through multiple queues (transmitter, bridge, [more
bridges/routers], receiver), the high priority packets tend to bunch up and
arrive in bursts that will require bigger buffers at the receiver.

There are simple fixes to all this however, providing that there is a
"network"-wide synchronization mechanism. (where "network" means the cloud
of interconnected devices that can share the synchronization method.)
