Discussion
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 change 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.
