Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] Combine first figure 1 Briefly introduce the application scenario of the data processing method provided by the embodiment of the present invention. see figure 1 , the first terminal 10 and the second terminal 20 are respectively connected to a software defined network (Software Defined Network, referred to as SDN) 30, and the data packet sent by the first terminal 10 to the second terminal 20 is forwarded to the second terminal 20 through the network device 40 in the SDN 30 Two terminals. Wherein, the network device 40 may be at least one of a switch, a router, and a gateway.

[0052] Specifically, see figure 2 , SDN 30 includes management plane 31, control plane 32 (i.e. control layer (controllayer)) and data plane 33 (i....

Abstract

The invention discloses a data processing method and apparatus, and belongs to the field of communication technology. The method comprises the following steps: obtaining the information of a head filed of a data packet; searching an accurate matching table entry matched with the data packet in an accurate matching flow table by using the information; when the accurate matching table entry matched with the data packet is searched, judging whether the updating time of a universal matching table entry corresponding to the accurate matching table entry is prior to the establishment time of the accurate matching table entry, wherein the accurate flow in the accurate matching table entry is a subset of rules in the universal matching table entry corresponding to the accurate matching table entry; when the updating time of the universal matching table entry corresponding to the accurate matching table entry is prior to the establishment time of the accurate matching table entry, processing the data packet according to the action instruction corresponding to the accurate matching table entry; and when the updating time of the universal matching table entry corresponding to the accurate matching table entry is not prior to the establishment time of the accurate matching table entry, deleting the accurate matching table entry. The updating of the flow table and the search of the flow table can be executed at the same time, thereby generating no processing delay of the data packet, and improving the network performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and device. Background technique [0002] The core of Software Defined Network (SDN) is to separate the control plane and data plane of network equipment, so as to realize centralized and flexible control of network equipment. Wherein, the control plane is used for providing flow entries, and the data plane is used for processing data according to the flow table generated by each flow entry. [0003] Before the data plane processes data according to the flow table, it will first determine whether the flow table is being updated. Only when the flow table is not updated, the flow table is searched for the flow entry matching the data packet, and then the data packet is processed according to the action instruction corresponding to the matching flow entry. [0004] In the process of realizing the present invention, the inventor finds that th...
