Introduction
This section provides an overview of PAM and a description of the facilities for
managing PAM.
Overview of Features and Architecture
PAM provides a set of standard programmatic interfaces that allows you to write
applications without regard to the underlying physical local area network (LAN). These
standard interfaces eliminate the need for separate sets of code for specific LAN types.
The PAM subsystem provides access to token-ring or Ethernet LANs on a Himalaya
S-series system.
The PAM Subsystem’s Role Within the System
The PAM subsystem consists only of software processes and interfaces and uses the
services provided by the SLSA subsystem to access the Ethernet and token-ring LANs
connected to the Himalaya S-series server. Figure 1-1 shows the components of PAM
and its relationship to other data-communication subsystems. The components and
related subsystems are described after Figure 1-1.
