Continuously monitoring link performance is important to network diagnosis. In this paper,
we address the problem of minimizing the probing cost and achieving identifiability in probe …

Quickly recovering IP networks from failures is critical to enhancing Internet robustness and
availability. Due to their serious impact on network routing, large-scale failures have …

The impressive growth experienced by the Internet in the last years, together with the
diversity in network technologies are posing more and more challenges in the field of …

Backup paths are widely used to protect IP links from failures. Existing solutions such as the
commonly used independent and Shared Risk Link Group models do not accurately reflect …

Detecting the occurrence of large-scale router failures and localizing the failed routers are
critical to enhancing network reliability. We propose a two-phase approach for detecting and …

Flow latency monitoring is a fundamental task in network measurement. The development of
software defined networking enables flexible flow latency monitoring in the control plane …

We consider the problem of detecting the presence of a spatially correlated multichannel
signal corrupted by additive Gaussian noise (iid across sensors). No prior knowledge is …

The Internet has become a significant and widely used infrastructure for a wide range of
communication and other services. Internet reliability and availability are crucial to many …

Large-scale network services bring great challenges to fault diagnosis, which include the
unpredictability of the fault, the difficulty of collecting the fault information, high cost and …
