Example Embodiment
[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0028] The method and device for realizing Ipfix detection based on flow rate disclosed in the present invention adopts a level flow table to realize Ipfix.
[0029] Specifically, such as figure 1 As shown, the method for implementing Ipfix detection based on traffic disclosed in the embodiment of the present invention includes:
[0030] S1, according to the packet header field in the flow to match the first-level flow table in the chip, identify the flow to be detected.
[0031] Specifically, take the switch chip to monitor IP traffic as an example. The switch chip includes an ACL engine and an Ipfix engine. The access control list (ACL) in the ACL engine is used as the first-level flow table, and the first-level flow table is configured to identify IP traffic. One keyword, the first keyword...
