Method and device for hierarchical control access of multicast group

Abstract

The invention discloses a method for hierarchical control access of a multicast group, which divides access right control layers for the multicast group and sets control rules for each control layer;and the method comprises the steps of carrying out right control on a visiting user at the current control layer according to the set control rules, denying the multicast group requested to be accessed by the user if the user does not pass the right control and entering the next control layer for carrying out the right control on the visiting user till completing all the set control layers if theuser passes the right control. Accordingly, the invention provides a device for hierarchical control access of the multicast group, which comprises a division module, a control module and a trigger module. Therefor, the method and the device can carry out hierarchical and flexible control on the multicast group demanded by the user, thereby improving the quality of the multicast group.

Description

technical field [0001] The invention relates to data communication technology, in particular to a method and device for hierarchically controlling access to multicast groups. Background technique [0002] Interactive Internet TV (IPTV) is launched by operators based on broadband. It utilizes Internet Protocol (IP) broadband network and integrates various technologies such as Internet, multimedia, and communication to provide users with live TV, video on demand, and Internet browsing. and other interactive services. Among them, the implementation process of IPTV can refer to figure 1 Shown: [0003] Step 101, the user terminal sends an Internet Group Management Protocol (IGMP, Internet GroupManagement Protocol) join (Join) message to request a multicast program; [0004] When a user terminal requests a multicast program, it sends an IGMP Join message to a Digital Subscriber Line Access Multiplexer (DSLAM, Digital Subscriber Line Access Multiplexer). The DSLAM is the centr...

[0010] 3) Restriction on the bandwidth that the current user can occupy;

[0014] As can be seen from the above, in the prior art, the user's authority control is only once, and is generally limited to an interface or virtual local area network (VLAN). However, for the rapidly developing IP network, operators need to provide higher quality service, then only controlling user permissions at one level cannot improve service quality at present. Therefore, hierarchical control of user permissions is required from multiple aspects

[0015] At present, in the user access control of IPTV, a single control plane is used, and there is no hierarchical control of user access.
