PURPOSE:To prevent lowering of the service rate of the outgoing circuit of a switch circuit network by adding plural pieces of subswitches in each channel stage. CONSTITUTION:Basic switch elements 21k-0-a (k=1 to 3, a=0 to 3) as circuits (switch elements) to determine a link to be connected based on a connection destination address given to communication information and rank 1 subswitches 21k-1-a and rand 2 subswitches 21k-2-a which are another switch elements are provided. Since plural subswitches are added in each channel stage, even if a fault is caused in a routing route, the communication information can be transmitted to the switch element of a next stage through the subswitch without transferring the communication information to the other switch in the same stage. Thus, the service rate of the outgoing circuit of the switch network can be maintained at a high level. |
