Input/output channel interface which automatically deallocates failed subchannel and re-segments data block for transmitting over a reassigned subchannel
Input/output channel interface which automatically deallocates failed subchannel and re-segments data block for transmitting over a reassigned subchannel
A multi-path channel interface for computer input-output systems includes the ability to define and activate unbalanced groups of unidirectional communications sub-channels for a user application. Protocol independent exchange identifications permit not only unbalanced transmission groups but also allow user-controlled extensions for negotiating the values of transmission parameters at the time the transmission group is activated. When error correcting re-transmissions force the re-segmenting of data blocks, second level sub-segment indexing assure the proper order of delivery of the various segments and sub- segments. The exchange identifications include an identification of the user protocol being supported and thus permit interfacing with any user protocol.
