ATM networks are supposed to transport all sorts of information covering voice and video with a wide variety of coding schemes and bandwidth requirements, and a wide spectrum of data from low-rate interactive applications through LAN/MAN interconnection up to high resolution animation graphics and graphics data base browsing. Despite many proposals made to date, some problems remain in providing a resource allocation and congestion control scheme suitable for all these services, particularly those with high peak bit rate or unpredictable burstiness.In this paper we examine some of the resource allocation techniques currently under discussion in the literature from the point of view of carrying packet data services. Not only is the traffic handling performance studied but we also compare the complexity and cost of their implementations.The proposed techniques fall into three categories: 1 - connection level bandwidth allocation, 2 - burst level bandwidth allocation and 3 - burst level buffer allocation. These particular techniques demonstrate a trade-off between the traffic performance and the complexity of implementation. From the efficiency of traffic handling point of view it is shown that the three techniques have their own areas of efficiency; namely the techniques 1, 2 and 3 are efficient when the access bit rate is restricted respectively to a small, modest or large proportion of the network trunk bit rates.
