Use of MoPC120 with modified firmware as a means to emulate Dial Up Users and load test Remote Access Servers (HiG 1000). The actual PPP traffic (load) originates from Linux PC(s) via PPPoE and the MoPC acts as a bridge between Ethernet and TDM.

Abstract

The problem to be solved is the lack of a device capable of simulating and testing the total number of users that can be accomodated by a Remote Access Server like the HiG 1000. Up to now third party hardware/software and ISTS CGs with limited functionality is used. The new solution is a reverse modem functionality inside the MoPC so that the software modems act as a client instead of as a server. It is used a Linux PC with PPPoE to produce PPP (Point-to-Point Protocol) sessions which then are carried out via PPPoE to the MoPC and then via E1 to the Remote Access Server. For a HiG1000 having 1 PHub and 2 MoPCs you need Linux PC(s) and 2 testing MoPCs to test it. The PPP sessions are all initiated by an ISTS PC which gathers all statistical data.

For this process neither special hardware is needednor has to be designed from scratch. The same Mo-dem Pool Card (used in a HiG1000 only firmwarehas to be changed) can be used to emulate Dial UpUsers. The functional...
