Abstract
The required length of a route descriptor in a source routing system is obtained by inserting an implied exit field, use of run-length encoding, and use of variable-length encoding. In the variable-length encoding, codes having lesser bits are reserved for preferred directions. Preferred direction may be encoded in the routing header, and it may be implied by the arrival port.
