Most ISPs rely on their upstream providers in achieving global reachability, thus they tend to make backup upstream links for the purpose of improving their own resilience. Yet, the Internet AS topology does not entail as much redundancy as it is widely thought, e.g., in our observation, 23.6% of all ASes only have single provider. Moreover, even though an AS has multiple upstream links, if all its...
Online social networks (OSN) are developing rapidly. Most prior OSN researches have been focused on network application layer. However, the social relationships and topology characteristics of OSN can be utilized to enhance the function, performance and security of network protocols in every layer. This paper presents the concept of social-aware plane and designs a novel model (EPSP) to enhance network...
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...
