APPN Networking Overview

APPN is an architectural extension of IBM Systems Network Architecture (SNA).

As participants in an SNA network, APPN nodes use distributed network services

for dynamic routing, connection, topology, and directory information, simplifying

network deﬁnition and maintenance.

Bay Networks routers participate as APPN network nodes in IBM SNA network

environments (with or without the presence of an IBM mainframe computer) and

communicate with adjacent network nodes, end nodes, and low-entry networking

nodes. APPN runs on all Bay Networks router platforms using local and wide area

network facilities, as follows:

• LLC2 media, including Ethernet, Token Ring, and Frame Relay

• LLC2 using Source Routing Bridge (SRB) encapsulation formats over

Ethernet, FDDI, SMDS, Frame Relay, and Point-to-Point (PPP) protocols

• SDLC links in point-to-point and multipoint conﬁgurations

The Bay Networks APPN implementation complies with Version 2 of the IBM

APPN Network Node speciﬁcation, with advanced optional APPN function sets.

APPN Node Types

APPN supports the following node types:

• Network nodes

• End nodes

• Low-entry networking nodes
