Embodiment Construction

[0073] In order to solve the problem of unified collaboration among network devices, the concept of Software Defined Network (SDN) was proposed. The SDN network includes a data transmission network composed of many data nodes such as switches and routers, and a control node that uniformly manages and controls all data nodes. The communication between the control node and the data nodes is based on the OpenFlow protocol.

[0074] The architecture of the current SDN network in the industry is as follows: image 3As shown, the SDN network is mainly composed of three layers: data plane, control plane and service plane. The data plane is mainly composed of switches or routers that support the OpenFlow protocol. This device needs to have three elements required by the SDN network on the basis of supporting the basic functions of data exchange and distribution: (1) Each data node device stores a A flow table that can be read and written by the control node. The flow table is compose...

Abstract

The invention discloses a software defined network (SDN)-based data processing system, which comprises a source data node, a source control node and a target control node, wherein the source data node is used for receiving a first data packet and transmitting the first data packet to the corresponding source control node; the source control node is used for receiving the first data packet, which carries a target address of the first data packet, transmitted by the source data node, and determining the target control node according to the target address of the first data packet; and the target control node is used for receiving the first data packet and generating a second data packet according to the first data packet and a matching strategy rule. According to the software defined network-based data processing system provided by the embodiment of the invention, the collaboration capacity between the nodes is improved so as to reduce redundancy for multi-node processing in network equipment and improve the business processing efficiency of a network. The invention also discloses a software defined network-based data processing method and a software defined network-based data processing device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, node and system for data processing in a software-defined network. Background technique [0002] At present, the device node networking mode of the general access network basically adopts a distributed and autonomous network structure. In this network structure, each network node is configured individually and works independently. This results in information asymmetry among network nodes, resulting in the inability to share business capabilities between different network nodes, lack of collaboration, and redundancy and duplication of business function execution, making the processing performance of the entire network poor. The following are some very common scenarios in which network node capacity allocation is unreasonable in network applications: [0003] 1) if figure 1 As shown, multiple client clusters and server clusters access the network throug...
