The global communication infrastructure of the Internet is formed by tens of thousands of Autonomous Systems connecting various organizations and individuals together. Having a global topology map of the Internet allows network researchers to understand the dynamics of the Internet in practice; guides network operators to enhance the reliability and security of their networks; allows network engineers to improve the efficiency of their systems; and helps developers to develop topology aware applications, among others.
In this dissertation, we study the implications of the Internet’s topological structure for its efficiency, security, and reliability. First, we developed a new mapping paradigm for the Internet’s topological structure: Cross-AS (X-AS) Internet topology mapping. Second, we developed a metric to identify the criticality of the autonomous systems in the Internet under targeted attacks. Next, we introduced a probabilistic packet marking defense framework against DoS attacks and the variants. Finally, we investigate the geographical properties of Internet routing.
