Chapter 1 NetIPC Fundamentals
Network Interprocess Communication (NetIPC) is a facility that enables
processes on the same or different nodes to communicate with each other
using a series of programmatic calls.
NetIPC3000/XL can be purchased as part of any NS 3000/XL link product.
It provides access to the Transmission Control Protocol (TCP), the
Transport Layer protocol used in NS3000/XL link products. Over an NS
X.25 network, NetIPC provides access to X.25 protocol features at level
3.
To communicate by means of NetIPC, processes must be executing
concurrently. One or more users (or programs) can run these processes
independently, or one process can initiate the execution of another by
using the Remote Process Management (RPM) Network Service. In
conjunction with NetIPC, RPM can be used to manage distributed
applications. Refer to theUsing NS3000/XL Network Services manual for
information about RPM.
Processes that use NetIPC calls gain access to the communication services
provided by the network protocols of NS3000/XL. NetIPC does not encompass
a protocol of its own; rather, it acts as a generic interface to the
protocols underlying the NS3000/XL network services.
This chapter is organized into the following major sections:
* NetIPC Concepts
* Using NetIPC for Interprocess Communication
* Direct Access to Level 3, X.25
* Considerations for using NetIPC between MPE-V and MPE XL HP 3000
systems.
