Problems solved by technology

[0008] However, in the prior art, RACF establishes the transmission path between the sender and the receiver and reserves the end-to-end transmission resources for the sender and the receiver. This method is only suitable for the unicast service at the transport layer, but cannot Transport layer multicast service requirements, so the existing technology can not realize the transport layer multicast service

Embodiment Construction

[0034] The invention provides a method and system for realizing multicast service and a resource and admission control unit, which are used for realizing multicast service in the next generation network structure.

[0035] Referring to Fig. 2, the overall flow of the method for realizing the multicast service in the present invention includes:

[0036] 201. The user initiates a multicast service request;

[0037] Wherein, the user applies for the multicast service to the service control unit. The service control unit implements the service control function, so it can be regarded as a service control function entity (SCF, Service Control Functions).

[0038] 202. Apply for establishing a path and apply for reserved resources;

[0039] Wherein, the SCF applies to the resource and admission control unit to establish a multicast path and applies for reserved space. The resource and admission control unit mainly implements resource management and admission control, so it can be ...

Abstract

This invention discloses a method for realizing multicast service, a system and a resource and admitting-control unit, in which, the method includes: a user applies for multicast service to a service control unit, which applies for setting up a transmitting path for the multicast and obligating resources to the admission control unit, which judges if it receives the application according to the network state, if so, it sends a control strategy to the transmission device, sets up multicast transmission path and obligates resources and the transmission device carries out multicast copy based on the control strategy. This invention also provides a related system to realize multicast service in the network structure of the next generation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing multicast service, and a resource and admission control unit. Background technique [0002] In order to ensure the end-to-end quality of service (QOS, Quality Of Service), in the NGN network architecture defined by ITU-T, between the service control function entity (SCF, Service Control Functions) and the transport function entity (TF, Transport Functions) , the resource and admission control function entity (RACF, Resource and Admission Control Functions) is introduced, which is used to implement end-to-end transmission resource negotiation and reservation for services in the access network and backbone network carrying services. [0003] When the service has the characteristics of multiple receivers at the same time, the multicast technology at the transport layer can reduce the service's requirements on the transmission bandwidth and the perf...
