Media streaming services are becoming extremely popular for end users with mobile devices. Peer-to-peer networking may be the solution to provide efficient streaming services for a large number of concurrent users without infrastructure. The client-server model costs a lot of money to manage and control and client heterogeneity also reduces the overall performance in mobile environments. Peer-to-peer...
User centric media service is about the user itself becoming the major media producer and distributor, and about exploiting this media created by different citizens at different moments of time to generate a co-created application. In this paper, we propose an architectural model of service overlay networking platform for future user-centric networking. Our platform composes a dynamic service overlay...
In this paper, We propose a resource control mechanism for NGN based home network. Multimedia services such as HD/SD IPTV service and VOD service require an available bandwidth without loss, delay and jitter as well as efficient data transport technologies. In order to support end-to-end QoS, plenty of technology has been introduced mainly to the access and core network. But this trend is moving toward...
SON (service overlay network) is an effective mechanism to support end-to-end QoS guaranteed contents delivery service for IPTV service in NGN. The advantage of the SON architecture is to reduce the complexity of network control and management. So the SON can help to provide end-to-end QoS to users. To provide SON service, the provider has to purchase bandwidth and QoS guarantees from the corresponding...
Within the NGN architecture, the resource and admission control functions (RACF) act as the arbitrator between service control functions and transport functions for QoS related transport resource control within access and core networks. The decision is based on transport subscription information, SLAs, network policy rules, service priority and transport resource status and utilization information...
In the NGN architecture, the resource and admission control functions (RACF) is aimed at providing real-time application-driven and policy-based transport resource management for a wide range of services and transport technologies. The RACF has two entities; PD-FE (policy decision functional entity) and TRC-FE (transport resource control functional entity). The PD-FE makes the final policy decisions...
