“…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. The drafts [30] and [31] present general guidelines for measuring various performance metrics in SR networks using STAMP.…”

“…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 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. Later on, the STAMP protocol has been extended to support SR networks (both SR-MPLS and SRv6) [31].…”

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.
