Network Services
NS3000/XL is the name of Hewlett-Packard's interactive and programmatic
user-level, network services. All of these services are listed below and
are fully documented in this manual:
* Virtual Terminal (VT) creates an interactive session for you on
another system in the network, making your terminal appear as though
it were directly connected to the other system. This service permits
you to issue commands to the remote operating system, use subsystems
such as editors and compilers within the remote environment, and run
application programs that reside on the remote system. A feature
called Reverse Virtual Terminal enables a local application program
to communicate efficiently with remote terminals.
* Remote File Access (RFA) enables you to perform I/O operations to
files and peripheral devices located on other nodes.
* Remote Data Base Access (RDBA) allows you to access and update
TurboIMAGE data bases located on other nodes. TurboIMAGE is a
Hewlett-Packard data base management system.
* Network File Transfer (NFT) allows you to transfer or copy files from
one node to another, or within a single node, interactively or
programmatically. For transfers to computer systems other than HP
3000s, refer to the NS Cross-System NFT Reference Manual.
* Remote Process Management (RPM) enables a given process to create and
terminate processes on other nodes. RPM is commonly used in
conjunction with Network Interprocess Communication (NetIPC). NetIPC
provides programmatic access to the Transmission Control Protocol
(TCP), which is the Transport Layer protocol used by NS3000/XL link
products. For more information on NetIPC, refer to the NetIPC
3000/XL Programmer's Reference Manual.
These network services allow you to perform essential functions across a
network or across gateways in an internetwork. In addition to a "virtual
terminal" you have what amounts to virtual storage and virtual devices;
you are not limited to the processing and storage capacities of your own
system.
