ABSTRACT
Diagnosing and solving problems in a contemporary data-center can be a daunting task. By merging network topology information with state collection, this poster abstract explores a new way to look at the network monitoring and troubleshooting problem. Abstracting the entire network as an entity simplifies the debugging process, making possible comprehensive root-cause analysis and exonerating the network administrator from dealing with many devices, delivering gains in productivity and efficiency. Such an amalgamation allows the translation of a performance query expressed in a domain specific language to small pieces of code operating on different devices in the network collecting necessary state. This merging results in lesser overhead per switch and reduces the strain on devices and provides a simple abstraction to the administrator.

Invulnerability analysis of scale-free network and small-world network
AI2A '23: Proceedings of the 2023 3rd International Conference on Artificial Intelligence, Automation and AlgorithmsThis paper analyzes the invulnerability of two kinds of networks with different degrees of distribution. According to their topology, four attack strategies and two metrics were selected. The most effective attack strategy and the most appropriate ...
Debugging native extensions of dynamic languages
ManLang '18: Proceedings of the 15th International Conference on Managed Languages & RuntimesMany dynamic programming languages such as Ruby and Python enable developers to use so called native extensions, code implemented in typically statically compiled languages like C and C++. However, debuggers for these dynamic languages usually lack ...
