Accurate Per-Flow Packet Loss Monitoring in SRv6
Segment Routing over IPv6 (SRv6) is a solution for IP backbones and Data Centers, which has been recently adopted in several large scale network deployments. A number of Internet Drafts have been submitted related to the Performance Monitoring of flows in an SRv6 network (SRv6-PM in short).
We present the implementation of a per-flow packet loss measurement (PF-PLM) solution based on the alternate marking method. The implementation is based on Linux kernel networking and is open source. Please fine hereafter the source code repository of two data plane solutions for packet marking and counting and one control plane solution for the generation and processing of Loss Measurement protocol packets.
This project is part of the ROSE project.
