Architecture of Next Generation Network with Information Sharing
Gufang Tu, Can Zhang, Yi Zhang, Derong Liu · 2006
In this article we present the architecture of the next generation network with information sharing by setting up access network protocol stacks and IP QoS over MPLS model to realize the inter-operation of heterogeneous networks, which maybe run by different operators or in various technology domains. This networking architecture is all-IP-based. It merges various types of networks, wired or wireless, fixed or mobile, backbone, local area or personal, by adding on an overlay network layer built on top of existing networks. It is referred to as knowledge management layer. Knowledge management layer is the peer - to - peer networking facility consisting of new hardware and software residing on top of IP edge router or media Gateway nodes. The proposed architecture provides all-IP-based information sharing. It enhances QoS support, security and mobility and network composition by managing and controlling the network state, behavior and resources in an optimized manner. Here in this article, we give an overview of the various network architecture, the evolution of the network architecture toward all-IP-based mobility networks with information sharing and then introduce the NGN architecture, its main features and access network protocol stack, which enables the NGN networks concept. Scalable coding and QoS control in the NGN, will be presented in more detail.
