Existing service measurements fall into two main categories: active and passive. This paper introduces another complementary technique called ‘inline measure-ments’ that makes use of the extendible features of the emerg-ing IPv6 protocol. Through the exploitation of native IPv6 extension headers, measurement triggers and measurement data may be carried in the same packets as the payload data itself, providing a high level of probability that the behaviour of the real user traffic flow is being observed. The paper also presents the results from a dynamically configurable proto-type implementation in which end-to-end, one-way delay and delay variation of real-time video streams have thus far been measured, as well as the ‘goodput’ of services operating on top of reliable transport.</ABSTRACT></RECORD></RECORDS></XML>
