research in the networking sector. One of the tasks of the ITU-T organisation in this area is to
develop a global architecture capable of managing end-to-end services to be used on future
specifications. This paper presents a signalling architecture proposal for the end-to-end QoS
management conforming the early ITU-T specifications for IMS/NGN networks, focusing on
the transport sub layer. The viability of the architecture has been validated through the …
