Subsystem
Architecture and Components of the WAN
Subsystem
The WAN subsystem software components that reside in the system processors
consist of:
One WAN manager process
One or more concentrator manager (ConMgr) processes
One or more SNMP trap multiplexer processes
One or more Trivial File Transfer Protocol (TFTP) server processes
One or more WANBoot processes
WAN shared driver
TCP/IP, NonStop TCP/IPv6, and Parallel Library TCP/IP
Systems LAN Access Subsystem (SLSA)
Figure 2-1 on page 2-4 illustrates the WAN subsystem software components and other
supporting processes. Also shown is an input/output process (IOP). The
data-communications subsystem objects, that function as line-handler processes are
typically referred to as IOPs. An IOP is configured by the WAN subsystem to use a
communications line on the SWAN concentrator. Other data-communications
subsystem objects, such as the Expand network control process ($NCP), are
configured by the WAN subsystem but do not use the SWAN concentrator.
