Unified interface between an IEEE 1394-1995 serial bus transaction layer and corresponding applications

摘要

A middle interface layer is positioned to provide a unified interface between applications resident within a node and the transaction layer of the node. The middle interface layer hides the details of the transaction layer from the applications. Unified response and request packets are used for communication between the applications and the middle interface layer. The middle interface layer is responsible for communicating with the transaction layer and generating and receiving all of the appropriate communications necessary for completion of transactions involving the applications.
