Embodiment approach

[0073] In this embodiment, after receiving the data packet to be forwarded, the virtual switch first judges whether the second source network address carried in the data packet to be forwarded matches the first source network address in the matching domain, and if it matches, determines The data packets to be forwarded need to be copied, and if they do not match, it is determined that the data packets to be forwarded do not need to be copied.

[0074] During specific implementation, after receiving the data packet to be forwarded, the virtual switch can extract the second source network address from the packet header.

[0075] In this way, all data packets sent by any virtual network element can be exported.

[0076] In the second processing manner, only the first destination network address is included in the flow table.

[0077] In this embodiment, after receiving the data packet to be forwarded, the virtual switch first judges whether the second destination network address...

Abstract

The invention discloses a virtualized network element data traffic exporting method and device and a storage medium, which are used for realizing the exporting of virtualized network element data traffic. A virtual switch is deployed in a network function virtualization environment. The virtual switch is used for connecting a virtual network card and a physical network card, and pre-configurationis performed to route data traffic of a virtual network element needing to export the traffic to the virtual switch. Also disclosed is a method, comprising: when the virtual switch receives a to-be-forwarded data packet, judging whether the to-be-forwarded data packet needs to be copied or not according to a pre-configured flow table; when the judgment result is yes, the virtual switch copying heto-be-forwarded data packet; and sending the copied to-be-forwarded data packet to a forwarding destination address set in the flow table.

Description

technical field [0001] The present invention relates to the technical field of mobile communication networks, in particular to a method, device and storage medium for deriving data traffic of a virtualized network element. Background technique [0002] In order to meet the requirements of the network operation analysis system and network optimization system, it is usually necessary to export the data flow between some network elements, extract useful data and provide it to the above-mentioned system, so that the above-mentioned system can perform big data analysis. In the traditional environment, network elements exist in the form of dedicated hardware, and the traffic between network elements is transmitted through physical lines. The traffic between network elements can be split and multiplexed in physical switches, and then output to the above-mentioned system. [0003] However, after the application of NFV, network elements are no longer implemented by dedicated hardwar...
