A Survey of the Use-It-Or-Lose-It Policies for the ABR Service in ATM Networks

The Available Bit Rate (ABR) service has been developed to support data applications over Asynchronous Transfer Mode (ATM). The ABR service uses a closed-loop rate-based traffic management framework where the network divides available bandwidth among contending sources. The ATM Forum then worked on incorporating open-loop control capabilities to make the ABR service robust to temporary network failures and source inactivity periods. One of the problems addressed was whether rate allocations of sources should be taken away if sources do not use them. The proposed solutions, popularly known as the Use-It-or-Lose-It (UILI) policies, have had significant impact on the ABR service capabilities. In this paper we survey the design, development, the final shape of these policies and their impact on the ABR service.
