Abstract

To support IP/PSTN convergence, future IP networks will need to provide reliable differentiated QoS to a diverse set of user applications, including telephony. To achieve end-to-end QoS solutions, IP network providers will need to agree on a common set of IP packet transfer performance parameters and QoS objectives. This article describes two new ITU-T Recommendations, Y.1540 and Y.1541, that document such an agreement.
