Dynamic and static charging of the ABR service in ATM network

Charging may be an essential condition for available bit rate (ABR) sources to adapt their traffic demand. In this paper we analyze different approaches for a usage-based pricing of ABR. We have classified these approaches as "static" and "dynamic". We refer as static a pricing scheme where the charging parameters are established at the connection set up and do not change afterwards, and dynamic otherwise. We analyze a static and a dynamic pricing scheme which have been already suggested. We propose new alternatives which solve some of their drawbacks, giving an analytical justification of the dynamic scheme. Finally, we confront the pricing schemes by means of a numerical comparison.
