Configuring Large X.25 Applications
This subsection describes some options for configuring OSI/TS and X25AM to support
large applications. To control X25AM lines, there are two options:
•
A single TSP process that supports all X25AM lines
•
One TSP process for each X25AM line
The advantages and limitations of each option are described in the following
subsections.
Characteristics of Large Applications
Large applications typically have at least some of the following characteristics:
•
The application can be reached by one single address. In other words, the
application is addressed by a single TSEL, which in turn, is addressed by a single
DTE address (or by a single NSAP address).
•
The total number of connections to be supported by the application could possibly
exceed the current limits supported by X25AM (250 circuits in systems using the C-
system version of the NonStop Kernel; 500 circuits in D-series systems) or could
possibly exceed the current limits supported by OSI/TS (512 connections in most
CPUs).
