- Scope
- In order to support provisioning and maintenance of IP-based networks, a common standard IP test packet format is desirable such that interoperability between test equipment and comparison of measurement results can be achieved. In order to measure the performance of IPv4 and IPv6 networks and services for different Type-P, there is a need for interoperability among heterogeneous manufacturer equipment in order to perform measurements of ITU-T Recs Y.1540 [4] and M.2301 [1] parameters (IPER, IPLR, IPTD, IPDV, IPSLB, IPRR) across administrative domains or composite networks. The packet format should facilitate not only the achievement of measurements between operator domains, but also the identification of the test manager who is in control of the measurement. This is analogous to previous requirements at the PDH/SDH (layer 1) and ATM (layer 2) network layers specified in ITU-T Recs O.181 [2] and O.191 [3]. The test packet must contain appropriate information needed to measure the main network performance parameters specified in ITU-T Recs Y.1540 [4] and M.2301 [1]. This Recommendation deals with the performance measurement of IP network services. Measurement techniques should also support the metrics specified by ITU-T Study Groups 2, 4, 9, 12, 13, 15 and 16, ATIS T1A1, ETSI TIPHON, EURESCOM, 3GPP and the IETF. The aim of this Recommendation is to standardize a common IP performance signature named IPPMS and test packets in order to measure the performance and the availability of IP network services across administrative areas, composite networks and among heterogeneous devices. The IP-layer supports many different IP-based services which may have different performance requirements, therefore the test packets must be, as far as possible, representative of the services being carried by the IPv4 and/or IPv6 layer for service turn-up tests, maintenance, troubleshooting and SLA monitoring. It is not in the scope of this Recommendation to specify the way in which the measures are activated or torn down, nor to define how measurements' results are managed. Nevertheless, the measurement signature should give room to identify a measure and its initiator.
