Overlay network testing

Lack of testing platform puzzled the research on overlay network. Recent research has shown that researcher can use Distributed Hash Tables (DHTs) to build certain applications, such as scalable, robust and efficient. Unfortunately, even though those applications have been implemented successfully, researcher is also hard to deploy large-scale distributed systems, nor are DHTs. Some worldwide platforms provide publicly accessible DHT service. Those kinds of platforms can issue at least put and get operations to any DHT node, which processes the operations on their behalf in contrast to the usual DHT model. This paper introduces overlay test-platform by an example of testing about resource location and concentrates on how to do the network testing based on it.
