Multiple sysplexes can be joined via standard network protocols such as IBM's proprietary Systems Network Architecture ( SNA ) or, more recently, via TCP / IP . The z / OS operating system ( MVS'most recent descendant ) also has native support to execute POSIX and Single UNIX Specification applications.

He was elected Fellow of the Institute of Electrical and Electronic Engineers ( IEEE ) and received multiple awards and honors, In 1981 he was awarded the IBM Fellow for " technical leadership in the development of system network architecture . "; in 1988 he received the Data Communications Interface Award; in 1989 the IEEE Simon Ramo Medal; and in 1992 he was elected members of the National Academy of Engineering ( Computer science ).
