A data processing method and device based on SDN

Abstract

The embodiment of the present invention provides an SDN-based data processing method and device, which is applied to an SDN network device provided with at least one virtual network card, each virtual network card is pre-bound with a network function, and can receive the first datagram text; modify the destination address of the first data packet according to the first flow table matched with the first data packet; if the modified destination address of the first data packet is the address of the virtual network card, send the first data packet to The virtual network card calls the network function bound to the virtual network card, performs corresponding network function processing on the first data message, and obtains the second data message; according to the second flow table matched with the second data message, modify The destination address of the second data message is forwarded according to the modified destination address. The method and device provided by the embodiments of the present invention can add and call newly added network functions without any additional settings for the OvS software itself.

Description

technical field [0001] The present invention relates to the technical field of data packet network function realization, in particular to an SDN-based data processing method and device. Background technique [0002] In a traditional network environment, the functions that can be realized by network devices such as switches are set by the manufacturer before leaving the factory, and users cannot add customized network functions to these network devices, which leads to specific network devices that can only realize specific network functions. To add a new network function to the network device, a new version of the hardware must be produced and installed by the manufacturer. [0003] In the Software Defined Network (SDN) network environment based on Open vSwitch software (OvS software for short), the functions that can be realized by network devices such as switches are also set by the manufacturer before leaving the factory. If you want to add a new network function, in addi...

Problems solved by technology

[0004] Although the custom setting of OvS software does not require replacement of hardware, these customizations must be performed by professionals of the manufacturer and cannot be done by the user, which not only increases the cost of adding network functions, but also prolongs the time for adding network functions

When these network devices are used to process data packets, the corresponding network functions cannot be called quickly and conveniently to process the data packets sent by the user host, which cannot meet the needs of users
