We introduce a number of simple conditions on networks which aid deadlock analysis either by localizing the analysis required for a proof of deadlock-freedom or by restricting the circumstances in which deadlock could occur. In particular, we formulate some simple theorems which characterize the states in which deadlock can occur, and use them to prove some theorems on the absence of global deadlock in systems. We identify a special class of ...

Dealing with deadlock has always been a crucial issue for any routing algorithms proposed for wormhole-switched networks.

This fact ... researchers to introduce adaptive routing algorithms based on deadlock recovery strategies.
