Experiences in emulating 10K AS topology with massive vm multiplexing

Abstract

New technologies that will be introduced to the Internet should be practically tested for effectiveness and for side effects. A realistic environment that simulates the Internet is needed to experimentally test such technologies, which will be widely deployed on the Internet. To support experimentation in a realistic, Internet-like environment, we are now trying to construct an Internet on a testbed. We describe our method of constructing an Internet-like environment on the testbed using a virtualization technology and estimation of the inter-AS network on StarBED with Xen and our prototype system. We stably constructed a 10,000-AS network using 150 testbed nodes and estimated its performance and feasibility.
