摘要: By enabling the deployment of softwarelized network functions on commodity servers, Network Function Virtualization (NFV) brings many benefits such as rapid development and deployment, simplicity flexibility in operations management. Monitoring performance characteristics Virtual Functions (VNFs), packet processing time, is crucial to achieving maximum benefit from NFV. In this paper, we present Packer Processing Time (PPTMon) - a solution for real-time lightweight VNF time monitoring. PPTMon embeds timestamp information directly into packets. implemented using extended Berkeley Packet Filter (eBPF) new Linux framework that allows high-speed processing. Our experiments showed can monitor VNFs with high accuracy low overhead.
