Abstract: There has been much interest in admission
control schemes that place the burden of admission control decisions on the end
users. In these schemes, referred to as Endpoint Admission Control, the
decision to join the network is taken by the user, based on the probing of the
network using probe packets. Depending on the level of congestion, routers mark
the probe packets and thus inform the user of the state of the network. In this
paper, we analyze three mechanisms for providing Endpoint Admission Control: virtual-queue
marking, random-early marking and tail drop. For each scheme, we analyze the
probing duration necessary to guarantee the required QoS and achieve high link
utilization. Our main conclusion is that very few probe packets have to be sent
when early marking is used, whereas tail drop requires a large number of probe
packets.
Note:
Sometime, concept implementation may differ from the concept in the base paper
to show the innovative technique which is must for any Master Project.
