               Network Performance Measurement for IPsec
                        draft-ietf-ippm-ipsec-00

Abstract

   IPsec is a mature technology with several interoperable
   implementations.  Indeed, the use of IPsec tunnels is increasingly
   gaining popularity in several deployment scenarios, not the least in
   what used to be solely areas of traditional telecommunication
   protocols.  Wider deployment calls for mechanisms and methods that
   enable tunnel end-users, as well as operators, to measure one-way and
   two-way network performance.  Unfortunately, however, standard IP
   performance measurement security mechanisms cannot be readily used
   with IPsec.  This document makes the case for employing IPsec to
   protect the One-way and Two-Way Active Measurement Protocols (O/
   TWAMP) and proposes a method which combines IKEv2 and O/TWAMP as
   defined in RFC 4656 and RFC 5357, respectively.  This specification
   aims, on the one hand, to ensure that O/TWAMP can be secured with the
   best mechanisms we have at our disposal today while, on the other
   hand, it facilitates the applicability of O/TWAMP to networks that
   have already deployed IPsec.

1.  Introduction

   The One-way Active Measurement Protocol (OWAMP) [RFC4656] and the
   Two-Way Active Measurement Protocol (TWAMP) [RFC5357] can be used to
   measure network performance parameters, such as latency, bandwidth,
   and packet loss by sending probe packets and monitoring their
   experience in the network.  In order to guarantee the accuracy of
   network measurement results, security aspects must be considered.
   Otherwise, attacks may occur and the authenticity of the measurement
