RE: [EFM] OAM - link sharing (was Faye's seven points)


I think you're talking about poor implementation practice here, as opposed
to poor standards' writing (unless you're arguing that the standards'
writers should have designed the protocol to accomodate arbitrary delays in
the generation of BPDUs, but I don't think that's what you meant).

BTW - Who remembers the problems caused by delayed BPDUs in spanning tree
protocol? There is a good example of the problems that can arise when
control traffic is mixed with payload if ever there was one :-). It was
addressed by some form of prioritisation I seem to recall. I stopped
following 802.1 in 1992, so others may care to expand on the detail.
