Peer Networking

Figure 5-2 shows a Tandem system as a database server providing information to PS/2

client applications connected through a Token-Ring local area network (LAN) and an

X.25 wide area network (WAN). Note that SNAX/APN supports X.25 permanent virtual

circuits (PVCs) only and that Himalaya S-series servers do not support native Token-

Ring connections at present.

The server and client applications are LU 6.2 applications, using the SNAX/APC API.

TLAM and X25AM are corequisite software for the Token-Ring and X.25 connections,

respectively.
