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.
NetIPC 3000/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 NS 3000/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 the Using NS 3000/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 NS 3000/XL. NetIPC
does not encompass a protocol of its own; rather, it acts as a generic
interface to the protocols underlying the NS 3000/XL network
services.
This chapter is organized into the following major sections:
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.
