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.
Claims14
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.
Apparatus for transmitting variable length messages on a network from a source having a source address to a destination having a destination address in fixed length slots, said apparatus including:
- a segmentation machine for 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,
- coding means for providing a source identifier field including a source identifier code which is uniquely associated with the message to be transmitted,
- means for entering said destination address in the message segment of said first slot, and
- a reassembly machine located, in use, at the destination, said reassembly machine including control means for controlling reassembly of slots in accordance with the source identifier codes of the slots.
