Clos Interconnection network is one of the known connection networks in processing systems and distributed systems, which is used extensively in many fields such as Telecommunication networks, ATM switches and Data transmission. In order to eliminate the blocking in such networks, various routing algorithm have been proposed, each imposing extra costs due to hardware use and re-routing algorithm. This paper offers a routing algorithm which takes a blocking-avoidance approach hence avoiding related costs. There is no blocking while the primary routing is performed from the input to output.
