Query language for large-scale P4 network debugging

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.
