The processing and decision making are performed at the
switch with the input as the link layer traffic traversing, in
both directions, a switch port. The number of hops between
the switch and end point will most likely affect the temporal
characteristics of traffic as observed at the switch. Queuing
and congestion tend to mask the temporal shaping of traffic
through end points. However, we consider scenarios that
involve network segments with, at most, 2 links from the
detecting switch. Such scenarios are commonly observed in
most Ethernet local networks. The reliability of wired links
makes the temporal characteristics of traffic, in a path, to be
