A Piecewise Linear Approach to Overbooking
You can read the actual paper here.
Abstract:
Overbooking is frequently used to increase the revenue
generated by a network infrastructure without incurring
additional costs. If the overbooking factor is chosen
appropriately, additional virtual circuits can be admitted
without degrading quality of service for existing
customers. Most implementations use a single factor to
accept a linear fraction of traffic requests. If a piecewise
linear approach is used in admissions, additional traffic
can be accepted without causing proportional increases
in loss rate and utilization. This additional accepted
traffic can significantly improve the profit margin for
network service providers.
Example
In the following figure the major network trunks are displayed. As each
trunk is different from all the others, we explain how breaking up the
overbooking ratio into different pieces is very beneficial and can
increase revenue for the telecommunications companies.
