We consider the problem of placing services in a telecommunication network in the
presence of failures. In contrast to existing service placement algorithms that focus on …

Fault localization is a process of isolating faults responsible for the observable
malfunctioning of the managed system. Previously, fault localization efforts concentrated …

Network function virtualization (NFV) is a powerful emerging technique with widespread
applicability. It provides Network Functions (NFs) through software virtualization techniques …

We investigate the capability of localizing node failures in communication networks from
binary states (normal/failed) of end-to-end paths. Given a set of nodes of interest, uniquely …

Microservice architecture has been widely used for the development of large-scale
distributed applications. Microservice systems normally have high complexity and loose …

Fault localization in enterprise networks is extremely challenging. A recent approach called
Sherlock makes some headway into this problem by using an inference algorithm over a …

Full knowledge of the routing topology of the Internet is useful for a multitude of network
management tasks. However, the full topology is often not known and is instead estimated …

SWIM is a peer-to-peer group membership protocol, with attractive scaling and robustness
properties. However, our experience supporting an implementation of SWIM shows that a …

As microservice architecture becomes prominent, existing fault management techniques to
deal with service disruption become limiting mainly due to the amount of data needed to be …

Finding the exact location of a fault in a large distributed microservices application running
in containerized cloud environments can be very difficult and time-consuming. We present a …
