“…In this section, we present the proposed End-to-End Delay Monitoring solution for SRv6 networks based on the Simple Two-Way Active Measurement Protocol (STAMP) [28]. STAMP enables the measurement of several performance metrics, including packet loss, delay, and jitter.…”

“…It supports both one-way and round-trip measurements in IP networks. RFC 8762 [28] defines the base functionalities of STAMP and describes the format of the packets that collect and carry measurement data. RFC 8972 [29] introduces the STAMP Session IDentifier (SSID) and defines optional STAMP extensions that enhance the STAMP base functions.…”

“…In this subsection, we describe our user-space implementations of the STAMP Session-Sender and Session-Reflector, compliant with RFC 8762 [28], RFC 8972 [29], and draft [31]. The implementations are based on Scapy [39], a packet manipulation library written in Python, Scapy provides a programming abstraction to generate and send network packets as well as to receive and decode them.…”

“…RFC 5357 defines both the test protocol (i.e., the format of the messages exchanged to collect the measures) and the control protocol (i.e., the protocol used to setup the parameters required by the measurement session). RFC 8762 [28] introduces a new protocol, known as Simple Two-Way Active Measurement Protocol (STAMP). RFC 8972 [29] proposes optional extensions, such as TLV (Type-Length-Value) coding to specify the Return Path.…”

Software-Defined Wide Area Networks (SD-WANs) are used to provide services to enterprises with geographically dispersed locations in a flexible and efficient way. We focus on SD-WAN services based on the Segment Routing over IPv6 (SRv6) technology. Performance Monitoring solutions are needed in SD-WANs to detect performance degradation and outages, and optimize network operations.In this paper, we describe a high performance solution for end-to-end delay monitoring for SRv6 based SD-WAN services. The proposed solution leverages the Simple Two-way Active Measurement Protocol (STAMP) to monitor the delay of an SRv6 path between two nodes called STAMP Session-Sender and Session-Reflector. We describe three implementations of the STAMP Session-Sender and Session-Reflector for a Linux software router and compare their performance. In particular, two implementations are based on user space processing and one is based on eBPF. The results show that the eBPF-based implementation outperforms the user space implementations and has a negligible impact on the forwarding capacity of the Linux software router.
