Problems solved by technology

However, when a multicast source is added or changed in the network, the existing solution needs to manually modify the outbound policy of the MSDP router in the local domain and the inbound policy of the MSDP router in the neighbor area. The SM domain may involve different operators, which will make the above operation very inconvenient; and the existing schemes cannot limit intentionally forged denial of service (Denial of Service; abbreviated as: DOS) attack message

Embodiment 1

[0035] Figure 2a It is a flowchart of a method for processing multicast source information provided by Embodiment 1 of the present invention. The executive body of this embodiment is an MSDP router, such as Figure 2a As shown, the method for processing multicast source information in this embodiment includes:

[0036] Step 201, the MSDP router generates a multicast source release message according to the obtained multicast source information, and broadcasts the multicast source release message in the domain;

[0037] Wherein, the multicast source refers to a device that publishes multicast data or provides multicast services, and the multicast source information mainly refers to the source Internet Protocol (Internet Protocol; IP for short) address of the multicast source, and the configuration of the multicast source. multicast address. The multicast source advertisement message mainly includes the information of the multicast source and the information of the MSDP route...

Embodiment 2

[0061] image 3 It is a flow chart of a method for processing multicast source information provided by Embodiment 2 of the present invention. This embodiment can be implemented based on Embodiment 1, and its execution subject is also an MSDP router, and the MSDP router in this embodiment and the RP in the PIM-SM domain are configured on the same device, that is, the router is configured with both PIM protocol and MSDP protocol. Such as image 3 As shown, the method for processing multicast source information in this embodiment includes:

[0062] In step 301, the multicast source sends a multicast message to a router directly connected to the source to register with the RP. The multicast packet carries information such as the IP address of the multicast source and the group address.

[0063] In step 302, the router directly connected to the source receives the multicast message, and encapsulates the multicast message to generate a source registration message; then, sends th...

Embodiment 3

[0077] Figure 4 It is a flowchart of a method for processing multicast source information provided by Embodiment 3 of the present invention. This embodiment can be implemented based on Embodiment 1, and specific similarities will not be discussed in detail. The execution subject of this embodiment is the MSDP router, and in this embodiment, the MSDP router is a device different from the RP. Such as Figure 4 As shown, the method for processing multicast source information in this embodiment includes:

[0078] Step 401, the router directly connected to the source receives the first multicast packet sent by the multicast source, generates a multicast source notification message according to the multicast packet, and sends the multicast source notification message to the MSDP router; wherein, MSDP The router will regularly broadcast the multicast source release message in the local PIM-SM domain; the source is directly connected to the router to obtain the information of the ...

Abstract

The invention provides a method, a device and a system for processing multicast source information. The method comprises the following steps of: generating a multicast source distribution message by a multicast source discovery protocol router according to acquired multicast source information and broadcasting the multicast source distribution message in a local domain; receiving a multicast source credibility notification message by the multicast source discovery protocol router and acquiring credibility multicast source information according to the multicast source credibility notification message, wherein the multicast source credibility notification message is generated and sent by a source direct connection router according to the received multicast source distribution message; and generating activity source information by the multicast source discovery protocol router according to the credibility multicast source information and sending the activity source information to a multicast source discovery protocol router in a target domain. The technical scheme can be used for effectively controlling multicast data on one hand, and improves the convenience for controlling the multicast data on the other hand.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a multicast source information processing method, device and system. Background technique [0002] With the rapid growth of network bandwidth and the number of network access users, broadband service operators are gradually shifting their focus from increasing the number of access users to increasing average revenue per user (Average Revenue Per User; ARPU for short). Among them, the Internet Protocol Television (IPTV for short) service is widely favored by broadband operators because it can eliminate bottlenecks of broadband user terminals and differences in technical implementation. [0003] The IPTV service is a service that uses a broadband network to provide users with interactive multimedia services. In order to ensure the viewing quality of users, IPTV technology generally adopts MPEG2 with a bandwidth of 3-4M or MPEG4 with a bandwidth of 1.5-2M, H.264 or other ...
