A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : UDP Checksum Trailer in OWAMP and TWAMP Author : Tal Mizrahi Filename : draft-mizrahi-ippm-checksum-trailer-00.txt Pages : 11 Date : 2014-01-14 Abstract: The One-Way Active Measurement Protocol (OWAMP) and the Two-Way Active Measurement Protocol (TWAMP) are used for performance monitoring in IP networks. Delay measurement is performed in these protocols by using timestamped test packets. Some implementations use hardware-based timestamping engines that integrate the accurate transmission timestamp into every outgoing OWAMP/TWAMP test packet during transmission. Since these packets are transported over UDP, the UDP checksum field is then updated to reflect this modification. This document proposes to use the last 2 octets of every test packet as a Checksum Trailer, allowing timestamping engines to reflect the checksum modification in the last 2 octets rather than in the UDP checksum field. The behavior defined in this document is completely interoperable with existing OWAMP/TWAMP implementations.
