During the interview session, basically we had been went through Gas Malaysia's Sdn Bhd Network& Server room and pay a visit on it. We get to know they currently having a TmNet 2Mbps direct lease line with another 1Mbps ADSL (Asymmetric Digital Subscriber Line) with a configured 4 Port Ascenlink Load Balancer as Multi Homing Device, their purpose of setting up load balancer was to get use and compile all 3 Mpbs Bandwidth and enforce their performance. This solution can be declared as a Multi Homing Solution network setup.
