Circuit emulation approach to traffic control in a B-ISDN

In this paper we propose a way to look at the congestion control problem in a B-ISDN that intends to gather the benefits of both circuit and packet transfer modes. We define a Circuit Emulation (CE) facility based on an admission policy at the edges of the network, and on a service discipline in the inner nodes that guarantees no information loss and no delay-jitter. On the other side, since a pure multirate-circuit emulation would be too inefficient for low bit rate bursty sources, we propose to use this facility only for a subset of the overall traffic
