Connectionless Data Server for Public ATM Networks: Design and Performance

The transport of connectionless datagrams is necessary for the compatibility of emerging high speed, wide area ATM networks with existing computer networks. This paper considers a virtual datagram network overlayed on the cell-based connection-oriented public ATM network to efficiently support high speed connectionless data service. This paper presents a detailed design for a connectionless server to implement the virtual datagram network, including a design permitting scalability. Simulation results are also presented to compare the performance of different connectionless service approaches.
