Network communications


Use this information to find out how to set up your system to communicate with clients and other systems.

Get started with communications
The system can use many different networking technologies. Use this topic collection to find more information about supported protocols including TCP/IP, APPC, APPN, HPR, Remote workstation, asynchronous, and binary synchronous communications.

Systems Network Architecture (SNA) includes the layered logical structure, formats, protocols, and operational sequences that are used for transmitting information units through networks. One example of implementing SNA to connect the i5/OS or iSeries server with other systems, to connect remote controllers and to maintain a high-level of security on your system, is through the use of APPC, APPN, and HPR.

Ethernet on the System i platform supports TCP/IP, Advanced Peer-to-Peer Networking (APPN), Advanced Program-to-Program Communication (APPC), retail, finance, host, and remote workstation.

Frame relay
Frame relay is a communications networking protocol that defines how frames are routed through a fast-packet network based on the address field in the frame.

OptiConnect is an IBM System i system area network (SNA) that provides high-speed connectivity between multiple systems in a local environment with wide area network (WAN) and local area network (LAN) technologies.

Token ring
This topic collection helps you plan, configure, manage, tune, and troubleshoot token-ring support for TCP/IP and Systems Network Architecture (SNA).
