Telecommunications networks are evolving towards an integrated ALL-IP architecture, commonly known as the Next Generation Network (NGN). The architecture consists of broadband transport technologies both on the access and core networks. One of the problems in NGN architecture is the ability to guarantee end-to-end Quality of Service (QoS) provisioning to the integrated network services in the form of voice, video, data, fax and IPTV. These services present complex QoS requirements on the transport networks. In this paper, the authors present an integration of the main components of a NGN on a test bed.
