Modern cloud native applications are generally built with a microservice architecture. To
tackle various performance problems among a large number of services and machines, an …

The fast and efficient failure detection and localization is essential for stable network
transmission. Unfortunately, existing schemes suffer from a few drawbacks such as …

With the surge of bandwidth demand for cloud applications and the exponential growth of
data, data center networks (DCNs) are expanding rapidly, followed by the daily increasing …

Persistent packet loss in the cloud-scale overlay network severely compromises tenant
experiences. Cloud providers are keen to diagnose such problems efficiently. However …

The fast and efficient failure detection and localization is essential for stable network
transmission. Unfortunately, existing schemes suffer from a few drawbacks such as …

In distributed database systems, as cluster scales grow, efficiency and availability become
critical considerations. In a cluster, a common approach to high availability is using …

We describe and experimentally evaluate the performance of our Network Link Outlier
Factor (NLOF) for locating faults in communication networks. The NLOF is a unique outlier …

With the transition of the 5G core network to a cloud native service-based architecture—
composed of network functions operating through microservices communicating over the …

This work presents the Network Link Outlier Factor (NLOF), a data analytics pipeline for
network fault detection and localization solution that consists of four stages. In the first stage …
