Performance enhancement in buffered delta networks using crossbar switches and multiple links
Abstract
It is shown that the throughput of buffered delta networks can be increased substantially by modifying the structure and operation of their crossbar switches, by using multiple links to connect the switches in the network, or by combining multiple delta networks in parallel. The variations tried in the structure of the crossbar switches are the size of the switch and the number of buffers in each switch, their capacity, and their position in the switch. Among the alternatives mentioned above, the use of two parallel links for each switch connection results in the highest throughput improvement. © 1984.
