Abstract
A printing system is provided for interfacing one or more session level protocols within the system to achieve an enhanced communications between the host computer and the network printer. A client server connection protocol (CSCP) facilitates this connectivity by providing a symmetric protocol for connections between servers and clients over connection-based stream-oriented protocols such as AppleTalk Data Stream Protocol (ADSP) and Transmission Control Protocol (TCP). CSCP resides in the presentation layer of the OSI seven-layer model and interfaces with one or more session level protocols. The dynamic port negotiation of CSCP facilitates concurrency for server applications by off-loading the port negotiation that would otherwise have to take place by the server and its clients. Thereby, CSCP allows the printing system to be easily extended and integrated with new protocol/ports as they are developed and introduced.
