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.
