摘要
Typical enterprises have multiple geographically dispersed branch offices.These branches host the users that need to access the applications hosted indata centers. A Software-Defined Wide Area Network (SD-WAN) interconnects thebranch offices with the data centers. We focus on SD-WAN services based on theSegment Routing over IPv6 (SRv6) technology. Performance Monitoring solutionsare strongly required to detect performance degradation and outages, andoptimize networks. In this paper, we describe a high performance solution for end-to-end delaymonitoring for SRv6 based SD-WAN services. The presented solution leverages theSimple Two-way Active Measurement Protocol (STAMP) and its extensions tomonitor the delay of an SRv6 path between two nodes called STAMP Session-Senderand Session-Reflector. We describe three implementations of the STAMPSession-Sender and Session-Reflector, two are based on user space processingand one based on eBPF. We compare the performance of our implementations. Theresults show that the eBPF-based implementation outperforms the user spaceimplementations and has a negligible impact on user traffic.
