You are making no sense at all.
Consider the case where only one flow exists. Two path exist, A and
B. Path A is used. It has a longer delay than B. The difference in
delay is N packet times. When switching from A to B, the first packet
to arrive on path B arrives N-1 packets before the last packet to go
into link B. Packets from that one flow are interleaved for about N
The case that we are talking about is moving a flow or group of flows
from one link to another. It is minimally disruptive. Do you have a
problem with that wording?
