wormhole routing
<messaging> A property of a message passing system in which each part of
a message is transmitted independently and one part can be forwarded to the next
node before the whole message has been received. All parts of a single message
follow the same route.
The independent parts are normally small, e.g. one 32-bit word. This reduces the
latency and the storage requirements on each node when compared with message
switching where a node receives the whole message before it starts to forward it
to the next node. It is more complex than message switching because each node
must keep track of the messages currently flowing through it.
With cut-through switching, wormhole routing is applied to packets in a packet
switching system so that forwarding of a packet starts as soon as its
destination is known, before the whole packet had arrived.
