Summary: 
We study buffer access policies which provide different loss priorities between two types of services, namely, real-time and nonreal-time services in ATM networks. Real-time services, such as video and voice, require the cell transmission with bounded delay. For these services, their available buffer sizes are limited by the delay bounds. We compare the performance of several buffering policies with bounded delay constraints of real-time services. Numerical results indicate that a simple buffering policy, called limited partial buffer sharing (LPBS) proposed in this paper, has a good performance for efficient use of ATM networks.
