Comparison of Border-to-Border Budget Based
Network Admission Control and Capacity
Overprovisioning

Abstract
There are two basic approaches to achieve Quality of Service
(QoS)
for communication networks: admission control (AC) and capacity
overprovisioning
(CO). CO is simple and is cheaper to implement than AC but AC requires
less capacity to fulfill QoS criteria since overload traffic can be
blocked. There
is an almost religious war between scientists working on both concepts.
In this
paper we try to contribute insights for this discussion by quantifying
the capacity
savings potential of AC under various networking conditions.
