Embodiment approach

[0083] An optional embodiment, the above-mentioned device also includes:

[0084] a first receiving module, configured to receive the first message sent by the connected first router;

[0085] a joining module for adding the first message to the queue to be processed; and,

[0086] The setting module is configured to set the last forwarding policy priority and the remaining matching times of the first slice clock cycle corresponding to the first packet as initial values.

[0087] An optional embodiment, the above-mentioned device also includes:

[0088] The second receiving module is configured to receive the second VXLAN message sent by the connected second analysis server;

[0089] a third obtaining module, configured to decapsulate the second VXLAN packet, and obtain the second packet carried by the second VXLAN packet and the remaining matching times;

[0090] A determination module, configured to determine whether the remaining number of matches carried by the second V...

Abstract

The present application provides a VXLAN-based message filtering method and device, which are applied to filtering equipment. The method includes: obtaining the current pending message in the queue to be processed; matching the current pending message with the forwarding policy set At least one control item; if it is determined that the current pending message matches a selected control item in the at least one control item, obtain the first analysis server corresponding to the forwarding policy to which the selected control item belongs; according to the The current to-be-processed message, the first analysis server, the forwarding policy priority of the forwarding policy to which the selected control item belongs, and the remaining matching times carried in the first chip clock cycle corresponding to the current to-be-processed message generate the second A VXLAN packet; sending the first VXLAN packet to the first analysis server. By applying the embodiments of the present application, the comprehensive analysis of the message is realized, and the analysis results are diversified.

Description

technical field [0001] The present application relates to the technical field of network communication, and particularly designs a packet filtering method and device based on Virtuale Xtensible Local Area Network (VXLAN). Background technique [0002] It is an effective means to maintain network security by monitoring and analyzing the packets in the network legally and filtering the illegal packets. Therefore, filtering devices have appeared. like figure 1 As shown in the figure, a filtering device can be connected between two routers to filter packets. The filtering device sends the received packets that meet the conditions from one router to the analysis server. After the analysis server analyzes the content of the packets, The packet is then forwarded to the filtering device, and the packet is forwarded to another router through the filtering device. [0003] The filtering device can establish multiple control functions by caring about the tuple information or tuple in...
