Abstract:
Routers making use of Random Early Detection (RED) queueing take
action to notify sources of growing congestion levels in the
network before their resources are exhausted. The RED system
hinges on two calculations: tracking the average queue size and
the probability that an incoming packet is marked for congestion.
These two calculations can be done in terms of the number of
packets arriving at the router or in terms of the size of those
packets (in bytes). Intuitively, these calculation methods offer
different costs and benefits to traffic. This paper
quantitatively assesses the impact of using the different queueing
and marking methods on the performance of traffic traversing a RED
gateway. We show that in some cases the calculation method makes
a difference in the performance of the system, while in other
cases the choice has little impact. We also provide a framework
for rating the RED variants in particular situations in an attempt
to aid in the choice of variant to use in a specific situations.
