Pursuing end-to-end quality control of multimedia communications in best-effort NGN environment that promotes access agnosticism and global mobility.

The Next Generation Networks (NGN) have become generally recognized as the telecommunications environment of the future. However, here several complex issues regarding quality assurance are presented that have not existed in the legacy environments, e.g. multi-network, multi-vendor and multi-operator IP-based telecommunications environment, distributed intelligence, third-party provisioning, fixed-mobile access, etc. In this article, service-aware policy based approach to NGN quality of experience assurance is presented.

A new approach to systematic quality assurance that affects all layers and all subsystems of the NGN environment.

Technically, delivering IPTV services to end-users involves both quality of experience and quality of service issues, whereas quality requirements are strict due to high bandwidth consumption and delivery in real-time. This paper demonstrates that the deployment of IPTV services within next generation networks architecture is possible, but requires additional quality mechanisms on service and transport layers. The focus of the paper is on quality assurance mechanisms. A study on converged admission control procedure is presented and a proposal for an extended end-user profile is given.
