SNA routing: Past, present, and possible future
Jeffrey M. Jaffe, Franklin H. Moss, R. A. Weingarten · IBM Systems Journal · 1983
This paper reviews the evolution of routing mechanisms in IBM's Systems Network Architecture (SNA) since its inception in 1974 to the present. Routing mechanisms are related to changes in the application and communications environment. Also discussed are possible evolutionary paths that may be taken in the future to address the problems of large heterogeneous networks.
