Abstract :
The relationships that currently exist between the Signaling System No.7 (SS7) and Open Systems Interconnection (OSI) architectures are examined. The functions of each layer in the SS7 protocol stack, as well as the SS7 addressing mechanisms, are described to the extent necessary to show correspondences to those of OSI. Those areas where the two architectures do not align are highlighted. The criteria by which alignment of SS7 with OSI standards is judged are explained. Work in progress in CCITT in defining the evolution of various SS7 application layer standards, where a conscious effort is being made to attempt to align with OSI standards, is described.<>
