Boundary Access Node

BAN is an IBM router enhancement. BAN refers to the RFC 1490 specification

for Bridged SNA over Frame Relay. The associated IBM NCP 7.3 enhancement is

called the Boundary Node Identifier (BNI).

Since BAN carries the destination and source MAC addresses in the network

packets, this format carries more bits per packet and requires less configuration.

Standard BAN uses the SRB frame format with local termination. Bay Networks

routers select BAN source route encapsulation when you configure the Frame

Relay network.

QLLC Support

QLLC provides reliable transport for SNA devices connected over an X.25

network. This support enables QLLC-attached devices to connect to a non-X.25

backbone, and allows non-QLLC devices to connect to an X.25 network. Both

single- and dual-switch DLSw networks can operate over X.25 links using QLLC.

For detailed information about configuring QLLC prior to adding DLSw single-

and dual-switch services, refer to Configuring X.25 Services.

DLSw/APPN Boundary Function

The DLSw/APPN boundary function (BF) allows DLSw to provide remote

communications via an IP backbone and provide access over this backbone from

enterprise-level applications using an APPN network.

The DLSw/APPN boundary function is implemented within a central APPN

network node. The BF accepts traditional PU2 traffic supported by DLSw and

routes it over APPN to the appropriate partner, typically a mainframe-based

application.
