Abstract
Transmission control improves the performance in a communications system relating to transferring large data objects between domains or applications. This reduces or eliminates data movement between domains by transferring ownership of the "container" containing the data as opposed to moving the contents of the container from one domain to another domain resulting in copying the large data object. Thus, transmission control provides for control of the transmission of relatively large data objects between domains in a communications system which otherwise only allows efficient transmission of relatively small data objects between domains in a communications system. Tokens are assigned and associated with buffers containing the data to be shared. The token is not an address, but rather an identifier for the buffer which can be transferred from one domain to a second domain without requiring the copying of the data. The domain which originally requests the buffer is assigned a primary token and secondary tokens are assigned to each subsequent domain which also requests access to the buffer.
