SNA TCP/IP Integration

Objectives
On successful completion of this course, attendees will be able to:

• describe the major characteristics of SNA and TCP/IP networks
• identify network integration objectives
• describe the addressing and naming schemes used in SNA and TCP/IP networks
• identify the differences between transparent bridges and source route bridges
• explain how SNA and TCP/IP can share a common bridged network via X.25, Frame Relay, and ATM
• explain how SNA/APPN and TCP/IP can be routed via multiprotocol routers
• describe how subarea SNA can be routed over TCP/IP using Data Link Switching
• describe how TCP/IP traffic can be routed over SNA using NCP as a router
• explain the operation of a gateway and describe the major gateway configurations
• describe how TCP/IP for MVS and VTAM act as a host gateway, and how Microsoft''s SNA Server acts as a LAN gateway
• explain how a network gateway operates and state the two main varieties
• explain the principles and operation of the Multi-Protocol Transport Network
• describe how access to existing CICS and IMS applications can be provided from TCP/IP hosts via the CICS Client/Server and CICS Web Interface products
• explain the principles and facilities of an SNA web co-processor
• describe how existing SNA green-screen user interfaces can be easily upgraded.

Who Should Attend
Network technicians, operators, managers and planners from both the SNA and TCP/IP environments.
Prerequisites
Existing knowledge of either (or both) SNA and TCP/IP are highly desirable, although a review of the operation of these networks is provided.
