Abstract
Abstract — Performance analysis techniques are fundamental to aid the process of large-scale protocol design and network operations. There has been a tremendous explosion in the variety of tools and platforms available (eg: ns-2, SSFNet, Click Router toolkit, Emulab, Planetlab). However, we still look at the sample results obtained from such tools with skepticism because they are isolated (potentially random) and may not be representative of the real-world. The first issue (random isolated results) can be addressed by large-scale experiment design techniques that extract maximum information and confidence from a minimum number of carefully designed experiments. Such techniques can be used to find “good ” results fast to guide either incremental protocol design or operational parameter tuning. The second issue (representativeness) is more sticky and relates to formulating benchmarks. In this paper, we explore the former case, i.e. large-scale experiment design and black-box optimization (i.e. large-dimensional parameter state space search). We propose a new platform ROSS.Net that combines large-scale network simulation with large-scale experiment design and XML interfaces to data sets (eg: Rocketfuel, CAIDA) and models (traffic, topology etc). This is a step towards the broader problem of understanding meta-simulation methodology, and speculate how we could integrate these tools with testbeds like Emulab and Planetlab. Examples of large-scale simulations (routing, TCP, multicast) and experiment design are presented.
