....approximate the boundary and approximate the bandwidth requirement (per connection) of each type by a constant independent of the traffic mix. These constants are called the effective bandwidth for each traffic type, and are often proposed as a means to simplify call admission control. In [6], an argument is made that the boundaries may be linearized without any significant reduction in the potential revenue subject to the traffic loads. In fact, unless such linearizations are done carefully, i.e. paying attention to the traffic loads and routing policies to be used, they can ....
....exists a resource pooling effect, see e.g. 33] and three VPs look like a big VP of larger capacity with the same effective bandwidth for each traffic type. Hence it might be advantageous to linearize the admissible regions identically on all VPs in order to simplify the routing algorithms. In [6], an argument was made that the boundaries of admissible regions can be linearized without significantly reducing the achievable revenue in high capacity networks. However, unless the linearization points are chosen carefully and appropriate routing policies are used to keep the networks around ....

....to linearize the admissible regions identically on all resources in order to simplify routing. However this simplicity will come at the cost of reduced network utilization, particularly for relatively small VPs, or shared resources which are expected to carry radically different traffic mixes. In [3], an argument was made that the boundaries of admissible regions can be linearized without significantly reducing the achievable revenue in high capacity networks. Nevertheless, unless the linearization points are chosen carefully and appropriate routing policies are used to keep the networks ....
