Problems solved by technology

[0005] It can be seen that the above-mentioned existing data traffic protection schemes are difficult to be simply applied to the data traffic protection on the user side due to their respective problems. In the absence of protection, when the main multicast router on the user side fails, it will cause multicast If the traffic is interrupted, the user needs to wait for the next Internet Group Management Protocol (IGMP) query before rejoining the channel corresponding to the multicast traffic by sending a report message, which will inevitably lead to a decline in user experience

Embodiment Construction

[0024] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, it is a scene diagram of the application of the embodiment of the active / standby protection system for the user side multicast service of the present invention. In this embodiment, the user side includes a first routing device (such as a Broadband Remote Access Server, Broadcast Remote Access Server, BRAS-1 for short) as a primary device and at least one second routing device BRAS-2 as a backup, exist figure 1 Only a second routing device BRAS-2 is schematically shown in the figure, and in other application scenarios, it may also include BRAS-3, BRAS-4, etc. as backups.

[0026] Both the first routing device BRAS-1 and the second routing device BRAS-2 are connected to the routing device in the IP / MPLS core network in the uplink, and are connected to the aggregation device 31, 32 or 3...

Abstract

The present invention relates to a routing device. The routing device and at least one second routing device are both connected to a convergence device. The routing device is an active device and includes a user information synchronizing backup module configured to synchronize multicast service user information to the at least one second routing device in real time through the convergence device. The present invention also relates to another routing device. The present invention also relates to a system and a method of active / standby protection for user-side multicast services. In the present invention, an active routing device and a standby routing device are configured on the user-side, and user information is synchronized to the standby routing device in real time. Therefore, upon active / standby switching, user identification and authentication are not affected, whereby the validity of user traffic and channel is ensured. Furthermore, economic benefits of an operator are guaranteed. Moreover, with the present invention, switching speed is accelerated, service continuity is ensured, and Quality of Experience of a user is improved.

Description

technical field [0001] The invention relates to the field of data flow protection, in particular to a user-side multicast service master-backup protection system, method and routing equipment. Background technique [0002] With the development of a large number of Internet Protocol Television (IPTV) services, the data traffic protection switching mechanism of the backbone network has been very mature, but when the link of the edge router on the user side fails, there is still a lack of a more effective group. Protection mechanism for broadcast service data traffic. [0003] Some multicast service data traffic protection schemes have been proposed in the prior art, such as multicast source active / standby protection. In the multicast source master / standby protection scheme, the multicast proxy server is connected to the multicast source master server and the multicast source backup server respectively, and the multicast proxy server provides cooperation for the multicast sour...
