Resource management method, system and network appliance

Abstract

The present invention discloses a resource management method, a system and network equipment thereof. The network equipment is directly or indirectly connected with the user equipment through at least one user link, and comprises a receiving unit and a resource management unit. The receiving unit is used for receiving the resource request which is triggered by the user equipment or the network-side equipment, when the user requests the first business through the user equipment. The resource management unit comprises a resource admission control module, a judgment module and a resource coordination module; wherein, the resource admission control module is used for providing the resource admission control function of the first business for the user equipment; the judgment module is used for determining whether enough usable user link resources is reserved for the first business; the resource coordination module is used for coordinating the occupied user link resources to satisfy the needs of the first business, when the judgment logic has determined that the usable user link resources are not enough. The technical proposal realizes the effective management of shared user link resources through the uniform resource admission control over the user link resources in the access equipment.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a resource management method, system and network equipment. Background technique [0002] IPTV video is a service with high bandwidth consumption, and packet loss is not allowed. However, network bandwidth, especially user link bandwidth, is generally very limited. In order to ensure the effective development of video services and service quality, Resource Management (Resource Management) must be deployed in the network. , RM) and Connection Admission Control (ConnectionAdmission Control, CAC) functions. [0003] In the IPTV service, there are two services of multicast / broadcast video (such as BTV) and unicast video (such as VOD). Since the business modes of multicast and unicast are very different, the realization of the CAC function is also different: [0004] Multicast CAC is generally completed locally at the access node (Access Node, AN). The AN judges whether the band...

AI Technical Summary

Problems solved by technology

However, the implementation of this solution is complex, and the frequency of multicast service switching is higher than that of unicast service. The frequent channel switching of a large number of TV users will lead to a large amount of information interaction, which requires very high performance of AN; and the channel switching of multicast service needs to interact with RM. , long switching time, poor user experience
