Getting started with System i communications

The iSeries server can use many different networking technologies. Supported protocols include TCP/IP, APPC, APPN, HPR, Remote workstation, asynchronous, and binary synchronous communications.

iSeries communications configuration is done by either manually or automatically creating a set of configuration objects that represent the local and remote systems that are to communicate. The types of objects that are created for a communications configuration depend on the type of communications being configured.

Networking concepts
If you want more information about networking concepts, review these topics.
Configuring your iSeries server for communications
Depending on the type of hardware, you need to complete these tasks to configure your iSeries server for communications.
Optimizing communications performance
Many factors can affect the performance of iSeries application programs. To achieve the best performance with your particular communications environment, review these topics.
Communications applications
Communications applications that are used in an Advanced Program-to-Program Communication (APPC) environment can also be used in an Advanced Peer-to-Peer Networking (APPN) and High-Performance Routing (HPR) environment.
Communicating with a host system
You can configure the iSeries system to communicate with a host system by matching iSeries system parameters. Another option for iSeries system users is dependent logical unit requester (DLUR).
Communicating with a remote iSeries server
Using Advanced Program-to-Program Communication (APPC), you can configure the iSeries server to communicate with another iSeries server. This configuration requires the coordination of configuration parameters and values.
Communicating with a remote workstation controller
You can configure the iSeries system to communicate with a remote controller. This configuration requires the coordination of configuration parameters and values.
Common networking standards
Local area network standards and wide area network standards are the two types of common networking standards that are supported by the iSeries system.
Troubleshooting communications problems
If you have a problem with the communications connectivity, you can use a set of tools that the iSeries system provides to analyze the problem.
