TitleThe evolving corporate internetwork: accommodating SNA
PublisherUniversity Video Communications
DescriptionFrom University Video Communications' catalog:
"The future of internets in the 1990's is characterized by the trend toward combining multiple disparate networks into a single global network. There are 50,000 operational SNA networks today, which account for at least 70% of all data communications traffic world-wide. This video covers one of the most important issues faced by today's corporate network designers: how to accommodate both SNA and multiprotocol traffic in a single network. The evolution of SNA is reviewed from its mainframe-centric origins in the early 1970’s through the new SNA that supports fully distributed processing. To illustrate the inter-operability of SNA, the layers of SNA, TCP/IP, and OSI are compared. Combining SNA with local area networks, as well as with multiprotocol internets, is examined from both an architectural and a product perspective."
