Border Gateway Protocol (BGP) plays a critical role in the Internet inter-domain routing reliability. Invalid routes generated by mis-configurations or forged by malicious attacks may hijack the traffic and devastate the Internet routing system, but it is unlikely that a secure BGP can be deployed in the near future to completely prevent them. Although many(More)
The critical requirement on reliability, fault-tolerance and security of network devices highlights the necessity of protocol robustness testing. Mutation testing of protocol messages is an important part of robustness testing, but related theory and practices are not well developed. This paper builds a NFSM model for mutation testing of protocol messages(More)
The inter-domain routing protocol, Border Gateway Protocol (BGP), plays a critical role in the reliability of the Internet routing system, but forged routes generated by malicious attacks or mis-configurations may devastate the system. The security problem of BGP has attracted considerable attention, and although several solutions have been proposed, none(More)
Due to the significant increase of peer-to-peer (P2P) traffic in the past few years, more attentions are put on designing effective methodologies of monitoring and identifying P2P traffic. In this paper, we propose a novel approach to measure and discover the special characteristics of P2P applications, the periodic behaviors, from the packet traces. We(More)
The protocol testing technology used in the next generation Internet should satisfy some new challenges and requirements. This paper focuses on the test suite description and test implementation techniques. TTCN-3 is chosen as the test suite description language and extended in both syntax and semantics to satisfy the requirements of protocol robustness(More)
Mobile IPv6 (MIPv6) protocol is a new protocol designed to support the node mobility ofIPv6 protocol, which is a basic protocol of the next generation Internet. Protocol testing consists of conformance testing, interoperability testing and performance testing. Protocol emulation testing, which we adopt in this paper, is a way of protocol testing.
