Transport protocols: Their performance and status in international standardization (July 1982)

This paper presents the agreements (by June 1982) which have been achieved on the international standardization level with respect to the Transport Layer. After defining the architectural environment of Transport Protocols, the functionality of the Transport Layer is described. This results in the identification of groups of Transport Layer functions and protocol classes. By this the specific performance of each protocol class is given. The quality of the service enhancement capability of each protocol class is emphasized. This paper does not present protocol details on formats and mechanisms. The actual status of the agreements between ISO, CCITT and ECMA and the short term expectations are given.
