Abstract :
The current discussion about ABR and LAN emulation shows the important role that data traffic is assumed to play in future ATM networks. In order to correctly support its characteristics like high burstiness and asymmetric load patterns, ATM switches have to provide large input buffers together with effective and flexible contention resolution mechanisms. This paper first presents the principles of a distributed approach for contention resolution. Based on shared medium access the communication between the single input buffers is integrated with the prevention of cell collisions at the switch output ports. In the second part flexible extensions for the support of priorities and multicasting are discussed. The paper concludes with the results of a VHDL-based feasibility study using a 0.7 μm CMOS standard cell library
