Abstract

This draft describes an active measurement method for SRv6 which can support hop-by-hop and end-to-end measurement on any SRv6 path using existing protocols such as IOAM. A packet containing an SRH uses a flag bit to indicate the packet is an active probing packet. The measurement information, such as the IOAM header and data, is encapsulated in UDP payload, indicated by a dedicated port number. The probing packet originates from a segment source node, traverses an arbitrary segment path, and terminates at a segment endpoint node, as configured by the segment list in SRH. Each segment node on the path, when detecting the flag, shall parse the UDP header and the payload. In the case of IOAM, the node shall process the IOAM option conforming to the standard procedures defined in the IOAM documents. The method is compatible with some other SRv6 active measurement proposals and support multiple applications.
