MODELING THE NETWORK PERFORMANCE OF DSL CONNECTIONS USING NETEM

With the increased use of internet based applications requiring low latency, and high bandwidth, the performance demands of the last mile network continue to grow. Additionally, the highly variant deployment scenarios of these technologies, have a high impact on their performance, creating difficult to replicate environments for application developers to test in, often requiring expensive and difficult to obtain equipment. This thesis attempts to model the networking performance of DSL using the open source tool NetEm. This is done by studying the latency performance of DSL connections under a range of conditions and configurations, to quantify the performance. That performance data can then be used to create delay models for using NetEm’s custom distribution delay models. These models can provide a powerful tool to test devices and software under simulated DSL conditions
