Abstract
Several research contributions and commercial ventures related to
wormhole routing, a switching technique used in direct networks, are
discussed. The properties of direct networks are reviewed, and the
operation and characteristics of wormhole routing are discussed in
detail. By its nature, wormhole routing is particularly susceptible to
deadlock situations, in which two or more packets may block one another
indefinitely. Several approaches to deadlock-free. routing, along with a
technique that allows multiple virtual channels to share the same
physical channel, are described. In addition, several open issues
related to wormhole routing are discussed
