1. A method of transmitting variable length messages on a network from a source having a source address to a destination having a destination address, said method including the steps of:
- segmenting each message into a plurality of fixed length slots including a first slot, continuing slots, and a last slot, each of said slots including a header field which includes a source identifier field, which is substantially shorter than said destination address, and a message segment;
providing a source identifier code in the source identifier field, each source identifier code being uniquely associated with the message to be transmitted;
entering said destination address in the message segment of said first slot;
transmitting the slots on the network; and
controlling reassembly of slots at the destination in accordance with the source identifier code of slots received at the destination.

Abstract
A method and apparatus for transmitting variable length messages on a network in fixed length slots including the provision of a source identifier field in the header of each slot, the source identifier field including a code which is uniquely associated with the message to be transmitted. The fixed length slots are then transmitted on the network and reassembly of the slots by a reassembly machine is controlled in accordance with the identifier codes in the slot.
