The ever-increasing requirements for performance, flexibility, and robustness are imposing a severe strain on the Internet's stagnated architecture. Network virtualization arises as a potential solution for improving the current situation by letting multiple networks with different requirements, architectures and protocols to coexist and share the same infrastructure in an independent way. These advantages...
Misconfigured P2P traffic caused by bugs in volunteer-developed P2P software or by attackers is prevalent. It influences both end users and ISPs. In this paper, we discover and study address-misconfigured P2P traffic, a major class of such misconfiguration. P2P address misconfiguration is a phenomenon in which a large number of peers send P2P file downloading requests to a ``random'' target on the...
Inter-domain routing system is the critical infrastructure of Internet. Make sure that autonomous system (AS) announces and prefers authentic routing information is very important to the security of inter-domain routing system. Due to BGP's opaqueness and AS's autonomy, it is difficult for AS to identify whether an incoming BGP route is valid. We design a reputation mechanism based on Bayesian probability...
This work proposes a probabilistic management paradigm for solving some major challenges of decentralized network management. Specifically, we show how to cope with 1) the overhead of redundant information gathering and processing, 2) the decentralized management in dynamic and unpredictable environments, and 3) the considerable effort required for decentralized coordination of management functions...
