Embodiment 1

[0035] Such as figure 1 as shown, figure 1 It is a flow chart of a method for detecting multicast traffic in a distributed communication device provided by an embodiment of the present invention. The flow chart of the multicast traffic detection method specifically includes the following steps:

[0036] S101. Configure a multicast traffic detection rule on the main control card, and obtain an incoming interface corresponding to the multicast traffic from a multicast forwarding table according to the multicast traffic detection rule.

[0037] In the embodiment of the present invention, in the embodiment of the present invention, the multicast traffic detection rule includes: multicast forwarding entry key (such as multicast source address, multicast group address, etc.), detection period and traffic threshold.

[0038] S102. Calculate a line card for forwarding the corresponding multicast traffic according to the acquired inbound interface of the corresponding multicast traff...

Embodiment 2

[0044] S201. Configure a multicast traffic detection rule on the main control card, send the configured multicast traffic detection rule to the delivery control module, and obtain corresponding multicast traffic from a multicast forwarding table according to the multicast traffic detection rule. The incoming interface.

[0045]In this embodiment, the main control card configures the traffic detection rule RULE_A, which includes: the multicast source address is 192.168.1.2, the multicast group address is 224.1.1.1, the detection cycle time is 10 seconds, and the traffic threshold is 10M. The action is to alert when the flow rate is lower than the threshold. The main control card sends the traffic detection rule RULE_A to the delivery control module, and the delivery control module searches the forwarding table management module for the corresponding forwarding of the multicast traffic (192.168.1.2, 224.1.1.1) according to the keyword of the multicast forwarding table item. Pub...

Embodiment 3

[0056] This embodiment provides a main control card, see image 3 As shown, the main control card is applied in the distributed communication equipment and connected with the line card in the distributed communication equipment. The main control card includes:

[0057] The rule configuration module 301 is configured to configure multicast traffic detection rules, and send the configured multicast traffic detection rules to the delivery control module 302 .

[0058] The delivery control module 302 is configured to obtain the incoming interface of the corresponding multicast traffic from the multicast forwarding table according to the multicast traffic detection rule, and calculate and forward the corresponding multicast traffic according to the obtained incoming interface of the corresponding multicast traffic. The line card of the multicast traffic sends the multicast traffic detection rule to the calculated line card; and is used to obtain the corresponding detection result o...

Abstract

The invention provides a method and a device for detecting multicast traffic in distributed communication equipment, which solve the problem that the application requirements for detection and control of multicast traffic are difficult to meet due to too high communication traffic between cards in the prior art. According to the specific solution, the method comprises: configuring a multicast traffic detection rule on a master control card, and acquiring an incoming interface of corresponding multicast traffic from a multicast forwarding table according to the multicast traffic detection rule; calculating a line card for forwarding the corresponding multicast traffic according to the acquired incoming interface of the corresponding multicast traffic, and transmitting the multicast traffic detection rule to the calculated line card; periodically detecting, by the line card receiving the multicast traffic detection rule, the corresponding multicast traffic according to the traffic detection rule, and reporting the multicast traffic detection result to the master control card. The method and the device effectively utilize the processing capability of the line card, thus relieving the pressure of the master control card and effectively reducing the communication interaction between the master control card and the line card.

Description

technical field [0001] The invention relates to the detection technology of multicast flow in the field of network communication, in particular to the detection technology of multicast flow in a distributed system. Background technique [0002] With the development of high-definition video on demand, multi-party video conferencing and other services, the communication equipment with centralized architecture can no longer meet the demand, and the distributed communication equipment with higher performance has been vigorously developed. A distributed communication device generally includes a line card (abbreviated as LPU) for data forwarding and a main control card (abbreviated as MPU) for protocol processing. The main control card completes the functions of the control plane, sends forwarding rules to the line cards, and the line cards complete the forwarding function according to the forwarding rules. The control and forwarding are isolated on the hardware, and the control p...
