Abstract

The invention discloses a SDN-based load balancing device and a method thereof. The load balancing device comprises a load balancing controller and a plurality of load balancing switches. The plurality of load balancing switches are connected to the load balancing controller through a base plane to establish an openflow channel, the load balancing controller is used for shunting decision and load monitoring. The load balancing switch parses and transmits or discards data traffic according to instructions issued by the load balancing controller. The SDN-based load balancing device shunts a control plane and a forwarding plane of the load balancing device so as to reduce the complexity of a load balancing system, improve the system maintainability, realize multi-device interconnection cascade, and reduce the development and production cost.

Description

technical field [0001] The present invention relates to a load balancing device and a method thereof, in particular to an SDN-based load balancing device and a method thereof. Background technique [0002] At present, the load balancing devices running on the live network are all special-purpose devices for private networks due to the particularity of the application scenarios. The software and hardware need to be designed and developed separately, and the cost is relatively high. For continuous upgrading, equipment manufacturers need to invest long-term manpower and material resources to ensure the stable operation and continuous optimization and upgrading of load balancing equipment. [0003] Due to the differences in load balancing implementation schemes of different manufacturers, each equipment manufacturer has its own maintenance management system and load balancing algorithm, which reduces network efficiency, brings various maintenance inconveniences, increases mainte...
