A new interconnection network composed of 3×3 switching elements is proposed. This new network is called Palindrome interconnection network (PIN) with hardware complexity identical to its counterparts. Compared with its counterparts, the proposed network is fault-tolerant, as totally disjoint paths exist in the network between any source/destination pair. In addition, for a given routing tag in the PIN, all the other equivalent tags which correspond to the same source/destination pair, can be derived easily. Computing an equivalent routing tag from a given routing tag requires the change of two bits of routing tag, irrespective of the network size, suggesting that rerouting logics can be incorporated into the constituent switching element comfortably without compromising performance. The proposed network exhibits higher terminal reliability than its counterparts
