Abstract
A method and apparatus for exchanging data in a network computing system having a main storage capable of connecting to at least one application server and an interface element with at least one adapter capable of establishing processing communication with at least one application user(s). A state change signalling protocol is used for transfer of data between the main storage and said adapter. In addition a queuing mechanism is established in the main storage having a plurality of queues each with a plurality of buffers. Some of these queues are dedicated to be input and others as output queues. By applying the protocol each input and output data buffer is associated with each of the active input and output queues. In this manner the input and output buffers are managed by placing the buffers into various states which are maintained in a special location that is set aside and is associated with each buffer. After complete transmission of data, the state of each such buffer is changed in order to make it buffer available for reuse.
