Installation

Before You Install the Software

OS Platform and Version Compatibility

The version of the X.25 link software you’re installing must be compatible with the version of HP-UX you’re running (for example, HP-UX version 11i v3 for B.11.31.01)

Disk space required to install: 7 Mb

Software install with system up or down? Up

Single-user state required or recommended? No

Reboot? Yes

Memory

Your X.25 link supports a high number of virtual circuits operating at high baud rates. Since both X.25 and the BSD sockets API may store a certain amount of data for each socket/circuit, HP recommends that you check that your system has enough memory to handle the number of VCs you plan to use. A few guidelines to help you are provided below.

Related Parameters

Level 3 window size (W in formulas below) as configured in the x25config file

Level 3 packet size (P in formulas below) as configured in X.25 configuration file

Socket buffer size (B in formulas below) used in your applications (setsockopt() system call). The default is 4 Kb.

Evaluation Formulas The following formulas can be used to evaluate

X.25 memory requirements:

Memory for each VC (MVC) in bytes:

MVC = (B x 3) + (2 x (W + 1) x P)

Total Memory (TM) for X.25 in bytes:

TM = sum (MVC) + Number of cards x 5120

NOTE

These figures are only for protocol and API requirements. You should

 

also consider the memory required by your applications.
