SUMMARYA mechanism for controlling the emitted traffic to asynchronous transfer mode (ATM) network, system design and implementation architectures are introduced. Specifically, the effective rate of a stream, defined under certain multiplexing conditions and quality-of-service specifications, is enforced to desired values by controlling the cell emission rate of the generated bursts. The traffic shaping mechanism is closely associated to an ATM transmitter, which is mainly responsible for ATM cell assembly and header error control. The mechanism has been designed to support data communication services. The whole system has been implemented as a VLSI circuit.

This paper gives a brief description and the main results of work done within the RACE 1022 project on bandwidth allocation and Connection Admission Control in ATM‐based networks. Additionally, and before presenting these two main issues, some important facets of statistical multiplexing are highlighted. The key question which is answered by a bandwidth allocation algorithm is “how much bandwidth is required by a group of connections (e.g., within a VP), with certain traffic characteristics, in a certain multiplexing environment”. Answers to this question are given for specific traffic classes and mixing conditions. The advantages and the limitations of the proposed strategies are indicated. In cases where the proposed bandwidth allocation strategies fail to fulfil the specified objectives (e.g., in highly heterogeneous traffic mixes), sophisticated CAC algorithms are required. In particular, the hierarchically organised CAC strategy implemented within the RACE 1022 ATD Technology Testbed will be described in detail. This CAC scheme is based on a simple real‐time processing algorithm which provides a quick acceptance decision. This decision will be refined by a precise but numerically complex background algorithm. Simulation studies confirm the potential of this concept.

Modelling of hyper-exponential ON/OFF traffic streams by a four-state Markov Modulated Rate Process (MMRP) is considered as a means of obtaining a sufficient(v accurate, yet computationally tractable analytical model for ATM traffic. A general formulation of the proposed model along with the associated multiplexing analysis is first developed. Then, a special time-reversible version of the model that arises naturally in many practical configurations of interest is analysed, which enables the modelling and the parameter assessment of the ON and OFF phases independently as two-stage, Erlang-type processes. Application examples with comparison of analysis, simulation and experimental results derived on an ATM testbed are given.
