NonStop System Glossary

VRO

See voluntary rendezvous opportunity (VRO).

WAN

See wide area network (WAN).

WAN concentrator

See ServerNet wide area network (SWAN) concentrator and ServerNet wide area network (SWAN)

2 concentrator.

WAN shared driver

A driver, provided as part of the wide area network (WAN) subsystem, that provides a simplified

interface to NonStop TCP/IP for use by I/O processes. The shared driver interface is similar to

that provided by DOIOPLEASE on earlier systems.

WAN subsystem

See wide area network (WAN) subsystem.

WAN subsystem manager process

A process named $ZZWAN provided as part of the wide area network (WAN) subsystem that

starts and manages the WAN subsystem objects, the WAN product process, and device objects.

Subsystem Control Facility (SCF) commands are directed to the WAN subsystem manager process

for configuring and managing the WAN subsystem and the ServerNet wide area network (SWAN)

concentrator.

WAN Wizard Pro

A graphical user interface (GUI) that guides you step-by-step through the configuration of wide

area network (WAN) and local area network (LAN) software and hardware.

WANBoot process

A process provided as part of the wide area network (WAN) subsystem that implements the BOOTP

protocol and provides management functions to the WAN subsystem and the WAN products.

wide area network (WAN)

A network that operates over a larger geographical area than a local area network (LAN); typically,

an area with a radius greater than one kilometer. The elements of a WAN can be separated by

distances great enough to require telephone communications.

wide area network (WAN) subsystem

The Subsystem Control Facility (SCF) subsystem for configuration and management of WAN objects.

wild-card character

A character that stands for any possible character or characters in a search string or in a name

applying to multiple objects. In Subsystem Control Facility (SCF) object-name templates, two

wild-card characters can appear: ? (question mark) for a single character and * (asterisk) for zero

or more consecutive characters. See also object-name template.
