In this work we consider the network stack for the most common virtualisation technology, Linux. We model the Linux networking stack based on the detailed analysis and monitoring of the performance of the various processes that occur in the network stack as the packets are forwarded to the network functions for processing. Based on the resultant model, we suggest and evaluate approaches for reducing the performance cost or avoiding unnecessary processes, in the context of Gi-LAN network functions.FulltextenBpftraceExtended Berkeley Packet FilterEBPFLinux networking performanceVirtual Network FunctionVNFConference PresentationMakute, T., Mwangama, J., & Lysko, A.
