Adopting a TCP/IP infrastructure is the first logical step to creating a multiservice
network that seamlessly accommodates data, voice, and video.
Enterprise organizations are heavily invested in mainframes and Systems
Network Architecture (SNA) and mainframes are still a vital part of enterprise
data centers. The goal for these enterprise organizations is to integrate the
TCP/IP-based environment with the SNA-based environment. Cisco bridging and
IBM networking technologies enable the delivery of SNA data over routers
supporting TCP/IP.
Cisco has developed a high-level, four-phase model illustrating a typical
integration path to incorporate TCP/IP into an SNA-based network.
illustrates the four-phase integration path. The model helps to describe some
common phases in SNA-to-IP integration. A single phase in this integration path
might represent the network of some organizations, while two or more phases
might represent the network implementation of other organizations in various
sectors of their network.
