| In multicast communication, it is often
required that feedback is received from a potentially very large
group of responders while at the same time a feedback implosion
needs to be prevented. To this end, a number of feedback control
mechanisms have been proposed, which rely either on tree-based
feedback aggregation or timer-based feedback suppression.
Usually, these mechanisms assume that it is not necessary to
discriminate between feedback from different receivers. However,
for many applications this is not the case and feedback from
receivers with certain response values is preferred (e.g.,
highest loss or largest delay). In this paper, we present
modifications to timer-based feedback suppression mechanisms that
introduce such a preference scheme to differentiate between
receivers. The modifications preserve the desirable
characteristic of reliably preventing a feedback
implosion. |
