The multi-service bearer network,built upon the Internet Protocol/Multi-protocol Label Switching (IP/MPLS) technology,is a converged network with Quality of Service (QoS) guarantee for business and enterprise customers. The integrated and unified service provisioning platform (including both service execution and development enviroments) can provide integrated audio,video and data services over multiple access networks. However,achieving network convergence and service convergence are long-term goals,which can only be realized step by step after comprehensive consideration of many factors like market demands,technologies,services and costs.展开更多

It hides the details of transport network to the service layer to support the separation of service control from transport function. It detects the resource status of transport network to secure a correct and reasonable usage of transport network resources. This accordingly ensures there are sufficient resources available to guarentee the appropriate level of QoS and avoid bandwidth and service stealing. The functional architecture, the entity involved and reference point, the access type and terminal, the resource control mode, the selection mechanism between functional entities, the interconnection between different domains, and the interaction between other transport control functions are the core study content of RAC. The RACS of the Telecoms & Internet Converged Services & Protocols for Advanced Networks (TISPAN) and the Resource and Admission Control Function (RACF) of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) differ in research focus. Consequently, the unification of Architecture, defined by different organizations, becomes the central issue of future research for each organization.展开更多

The introduction of the QoS resource control architecture based on the IP Multimedia Subsystem (IMS) framework is a way to solve QoS problems in the converged networks. Services,QoS guarantee,resource control and accounting functions are integrated into this IMS-based QoS control architecture. It is a solution to the problems currently facing the fixed network operators,helping them offer more QoS-guaranteed multimedia services such as 3D games,and make a transition from bandwidth providers to genuine telecom services providers.展开更多

With a gradual progress in standardization, this field presents new development trends and features. Based on latest progresses in standardization promoted by ITU-T, TISPAN and 3GPP, new technologies concerned with resource control are introduced. Considering the problems faced in standardization deployment, relevant resource control functions are also analyzed in this article.展开更多
