Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is some embodiments of the present invention, but not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] SDN is a new type of network architecture, which can separate the control plane and data plane of network equipment through OpenFlow (Open Flow) technology, so as to realize flexible control of network traffic. In SDN, it includes a controller that realizes the function of the control plane and several switches tha...

Abstract

The invention provides a SDN-based protocol port protection method, apparatus and system, wherein the method comprises the following steps: a controller pre-sets a SDN-based protocol port protection algorithm configuration task sequence, wherein the task sequence comprises a static protocol port policy table; receiving a message of unmatched flow table reported by a switch , acquiring the source IP address, the destination IP address and the message type of the message, and matching a static protocol port policy table; if there is a matched table item, acquiring network topology structure and determining a forwarding path according to the source IP address, the destination IP address, and the network topology structure, and adding the forwarding path to the flow table to be issued to the switch so that the switch forwards the message according to the forwarding path. The SDN-based protocol port protection method, apparatus and system are based on a SDN, all configuration is concentrated in the controller, and the configuration is convenient and simple.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data communication, and in particular to a method, device and system for web page level load balancing based on SDN (Software Defined Network, software defined network). Background technique [0002] The traditional protocol port protection algorithm protects the device from being attacked by other users on the network. In the default state, the status of each protocol on each access port of the device is closed, and the related protocol packets sent by other devices are not It will be processed by the system so that it will not be attacked. Only when the relevant protocol on the port is enabled, the port number of the protocol is released, and the system can process normally. [0003] The whole process of the traditional protocol port protection algorithm is as follows: figure 1 shown. Clients and servers communicate through switches, such as switch S1 and switch S2. When th...
