Method and system for implementing reserved request of multicast resource

Abstract

The present invention relates to the communication field, and discloses an implementing method and system for multicast resource reservation request. In the method, a local access and admission control functional entity is provided in the bearing layer, wherein the local access and admission control functional entity is used to achieve at least one of the following functions: differentiating resource reservation requests, and extracting the multicast resource reservation request; analyzing the relevant parameters of the multicast resource reservation request; interacting with the functional entity at the bearing layer, and acquiring the related information of the multicast tree; making the resource access and admission control decision. Adoption of the present invention, on the one hand, effectively realizes the reservation of the multicast resource requested in the bearing network; on the other hand, simplifies processing of RACs to the single broadcasting resource request.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a method and system for realizing a multicast resource reservation request. Background technique [0002] In the next generation network (NGN, Next Generation Network), in order to provide end-to-end service quality assurance for the business, a new resource admission control sublayer is added between the service control plane and the transport plane, responsible for admitting the resources of the transport network Control that enables the application layer to request the reservation of transport resources. in, figure 1 It shows the architecture of resource admission control in the existing NGN network. [0003] In the current RACS (Resource and Admission Control Subsystem, resource admission control subsystem) architecture, only unicast resource requests can be reserved, but multicast resource requests cannot be reserved. However, with the development of multicast servi...

Problems solved by technology

[0003] In the current RACS (Resource and Admission Control Subsystem) architecture, only unicast resource requests can be reserved, but multicast resource requests cannot be reserved.

However, with the development of multicast services such as IPTV in various places, there is an urgent need to realize the reservation of multicast resource requests by RACS. However, this has become a real problem, and no effective solution has been found yet.
