Network traffic measurement is central to successful network operations, especially for
today's hyper-scale networks. Although existing works have made great contributions, they …

Network operators often face the problem of remote outages in transit networks leading to
significant (sometimes on the order of minutes) downtimes. The issue is that BGP, the …

The use of real-time multimedia or mission-critical applications over IP networks puts strong
pressure on service providers to operate disruption-free networks. However, after any …

A cardinal prerequisite for the proper and efficient management of a network, especially an
ISP network, is to understand the traffic that it carries. Traffic profiling is a means to obtain …

Internet routing events are known to introduce severe disruption to applications. So far
effective diagnosis of routing events has relied on proprietary ISP data feeds, resulting in …

In this paper, we implement and evaluate a system that predicts and tracks Internet path
changes to maintain an up-to-date network topology. Based on empirical observations, we …

Persistent routing loops on the Internet are a common misconfiguration that can lead to
packet loss, reliability issues, and can even exacerbate denial of service attacks …

Manageability and high availability are critical properties for IP networks. Unfortunately, with
link-state routing protocols commonly used in such networks, topological changes lead to …

Understanding fluctuations in network performance is important as many applications,
including streaming, conferencing, gaming, and financial transactions, rely on timely delivery …

Since the early 2000's, Internet topology discovery has been an active research topic,
providing data for various studies such as Internet modeling, network management, or to …
