NS 3000/iX Network Services are composed of user
services, each of which performs a specific task. These services
are VT, Reverse VT, NFT, RPM, RFA, RDBA, LOOPBACK and NSSTAT. Refer
to Using NS 3000/iX Network Services for
details on Network Services.
To function, Network Services require Network Interprocess
Communication (NetIPC), the user interface included with NS 3000/iX
links. NetIPC is used extensively by the Network Services when processing
service requests and is available for use in customer applications.
It is not a service in the same sense as VT or RFA, since it consists
of a set of intrinsics and associated code in the system SL and
NL. NetIPC intrinsics are described in the NetIPC 3000/XL
Programmer's Reference Manual.
The NETCONTROL START command must be issued
before NSCONTROL START. This is because the NETCONTROL
command controls the network transport subsystem, which must be
initiated before the Network Services or any NetIPC application
can successfully execute. NetIPC depends on the network transport
to identify sockets and exchange messages. Refer to the NETCONTROL START
command, also described in this section.
