Embodiment Construction

[0026] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0027] like figure 1 As shown, the embodiment of the present invention provides a method for message data control, which is applied to a routing device and includes the following steps:

[0028] Step S101 , acquiring the priority of each pseudowire PW in the multicast network topology.

[0029] In this step, the topology of the multicast network is as follows: figure 2 As shown in the figure, AGG represents the aggregation layer device, and ACC represents the access layer device. AGG and ACC form a ring topology. Each AGG or ACC is a node. By blocking and restoring the two Layer-2 multicast forwarding function, realizing the forwarding and switching of Layer-2 VPN multicast on the ACC. Before the forwarding process, you need to configure the forwardi...

Abstract

The invention provides a message data control method and apparatus. The method comprises the following steps: obtaining the priorities of pseudo-wires PWs in a multicast networking topological structure; screening out the PWs according to the priorities of the PWs and a preset screening condition to obtain a target PW; generating a blocking message, wherein the blocking message comprises a name ofthe target PW, an Internet Protocol IP address of the target PW and a preset first message code; and sending the blocking message to the multicast networking topological structure. In this way, a two-layer multicast forwarding function of the target PW is destroyed just by configuring the forwarding attributes of the multicast networking topological structure and blocking the target PW, and on the premise of not affecting the traffic forwarding of nodes in the multicast networking topological structure, the configuration process is simpler, and the configuration cost is reduced.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method and device for message data control. Background technique [0002] Multicast is one of three modes of IP (Internet Protocol, Internet Protocol) data transmission, and multicast has higher data transmission efficiency than unicast and broadcast. When the network terminal needs specific information, the multicast source sends the information once, and the multicast router establishes a tree route for the multicast data packet with the help of the multicast routing protocol, so that the transmitted information can be replicated and distributed at as far as possible forked nodes. Forward. And multicast VPN (Virtual Private Network, Virtual Private Network) is widely used to provide a more secure network transmission environment. Multicast VPN is divided into two types: Layer 2 VPN and Layer 3 VPN. [0003] At present, the commonly used multicast networking method is conce...
