Concurrent transmission and short loop latency protocol

A novel destination partial removal protocol, DRUID (destination removal without intermediate node delay) ring, is proposed for ring-type networks. In the DRUID ring, a node may initiate message transmission if its output link is free. Every node will relay the message immediately if it is idle when the message arrives. At the same time, the node also receives and buffers all incoming messages. Upon decoding the destination address, the destination node will truncate the message frame to a cut frame by eliminating the information field. This cut frame will continue to circulate around the ring until it arrives at a busy node where it is buffered, identified, and removed. The message frame will be completely removed by the destination node if it is busy when the message arrives. The protocol supports high concurrency while the loop latency is minimized
