The data centers used to create cloud services represent a significant investment in capital
outlay and ongoing costs. Accordingly, we first examine the costs of cloud service data …

In recent years, configuration errors (ie, misconfigurations) have become one of the
dominant causes of system failures, resulting in many severe service outages and …

Network management facilitates a healthy and sustainable network. However, its practice is
not well understood outside the network engineering community. In this paper, we present …

Computer networks are hard to manage. Given a set of high-level requirements (eg,
reachability, security), operators have to manually figure out the individual configuration of …

Enterprise networks are important, with size and complexity even surpassing carrier
networks. Yet, the design of enterprise networks is ad-hoc and poorly understood. In this …

This paper presents a digital twin platform towards automatic and intelligent management for
data center networks: NetGraph. It builds a virtual image of the physical network, which …

Misconfiguration is a major cause of system failures. Prior solutions focus on detecting
invalid settings that are introduced by user mistakes. But another type of misconfiguration …

System failures resulting from configuration errors are one of the major reasons for the
compromised reliability of today's software systems. Although many techniques have been …

The realm of cybersecurity is perhaps one of the most quickly evolving areas within today's
research space. New and emerging technologies, as well as the growth of cybersecurity …

Software configurations play a crucial role in determining the behavior of software systems.
In order to ensure safe and error-free operation, it is necessary to identify the correct …
