Has anybody actually seen problems with out of sequence packets in
real life scenarios. The scenario I am interested in is the typical
example where there are switch paths to the same destination with one
link for example 2M and the other 1M? Does anybody have any proof of
concept testing done in a Lab were they can confirm at what different
speed ratios you are sure to experience problems based on certain
types of switching etc? I appreciate that there are a lot of
variables in this equation, e.g. type of switching, size of traffic
streams etc, etc. Any information/ experiences would be appreciated.
Can Variance overcome this issue ? Without reviewing my notes, I can
not remember whether Variance switches on stream or packet. If it is
stream. In theory, if a Router is performing stream switching, is it
fair to say that there should be no out of sequence issues due to the
fact that the entire stream is following a single path with fixed
speeds. If per packet switching is in use, they there maybe issues
with out of sequence packets due to the packets belonging to the same
stream being switched via different speed links.
I could go on an on........ :~)
