Problems solved by technology
[0004] (1) The independent DDOS defense equipment is connected in series in front of the load balancing equipment. On the one hand, the network deployment structure of the load balancing system is complicated, which increases the deployment cost of the network. On the other hand, the data packets need to be processed by the DDOS defense equipment, increasing the transmission time time delay
[0005] (2) The independent DDOS defense equipment connected in series in front of the load balancing device is independent of each service of the load balancing device. When a network attack against some or a certain business occurs, the DDOS defense device cannot effectively detect the type of business distinguish
[0006] (3) The DDOS defense device cannot enable or disable the defense function for some or a certain business, but can only enable or disable network attack defense for all business traffic, which makes the load balancing device inefficient

The invention provides a load balancing device and a load balancing and defending method. The device comprises a configuration module used for configuring addresses of server clusters of services and flow threshold of the services, a receiving module used for receiving a service request from a client, a monitoring module used for monitoring actual flow of the services of the request corresponding to the service request, a scheduling module used for scheduling flow distribution of the servers according to the actual flow of the requested services and a defending module used for judging whether to defend according to the requested services according to the actual flow of the requested services and the flow threshold of the requested services. By means of the load balancing device, different business types can be distinguished to start attack defending function aiming at businesses with attack aggressive behavior and close the defending function for the businesses free of aggressive behavior. The device and the method reduce operation burden, simplify network arrangement structure and simultaneously reduce data package transmission delaying.
Description
Technical field [0001] The invention relates to the technical field of network communication, in particular to a load balancing device and a load balancing and defense method. Background technique [0002] Load balancing equipment (Load Balancer, LB) can provide a general load balancing method for a variety of different services. Load balancing equipment mainly faces the following problems. On the one hand, all business data packets need to be processed by the load balancing equipment. If a business is attacked by a network, the load balancing equipment will withstand more than the flat rate of traffic, which will cause the load balancing equipment to work abnormally. On the other hand, if a single or part of a business is attacked by a network, it will affect the normal operation of all businesses on the load balancing device. Therefore, load balancing equipment needs to effectively defend against network attacks. [0003] The prior art uses an independent DDOS (Distributed Deni...
