PATH SELECTION CONTROL METHOD FOR WAITING TYPE SWITCHING NETWORK

摘要

PURPOSE:To prevent a flow of packet from being concentrated to a specific link in a switching circuit network by transferring a packet through a single path connected to a link having less flow of an existing set channel at all times so as to keep the sequence of packet. CONSTITUTION:The flow of existing set channel is compared as to in total four links of two links 3 connected between two output terminals of an optional unit switch (S) 1 of an input stage 4 and two partial switching networks 2-1, 2-2 and two links connected between two input terminals of an optional unit switch S1 of an output stage 5 and two partial switching networks 2-1, 2-2 to check which link has a maximum flow and to select a path not including the maximum flow link in two paths comprising 4 links. The path is selected in the path selection in the partial switching network in a recurrsive way sequentially according to the method above.
