Embodiment Construction

[0019] Below in conjunction with accompanying drawing, provide the specific embodiment of the present invention. It should be noted that the parameters in the examples do not affect the generality of the present invention.

[0020] Taking a dual-channel 2.5G (OC-48 interface, VC-4-16C cascading technology) high-speed data network as an example, the dual-channel 2.5G data flow is balanced to 8 Gigabit Ethernet (GBE, GigaBit Ethernet) interfaces , assuming that the system implementing this method is called an equalizer.

[0021] The specific design idea of ​​the present invention is to adopt a dynamic adaptive hash (HBDC, Hash Balancing and Dynamic Compensation) equalization strategy that combines static equalization and dynamic adaptive equalization, that is, the front end of the equalizer adopts a hash equalization algorithm to convert high-speed data The flow is mapped to each queue, and each queue stores the instruction information of the Internet Protocol (IP, Internet Pro...

Abstract

The invention discloses a load balancing method of a high-speed network. Aiming at the problem of low balancing degree of the traditional load balancing method, the invention provides a load balancing method of a high-speed network, which comprises the steps of: extraction of front information of an IP data packet, Hash operation, queue distribution and storage management, multimodal parallel classification and scheduling. The load balancing method utilizes a dynamic self-adaptive Hash balancing strategy combining static balancing with dynamic self-adaptive balancing to ensure that the current flow load condition can be effectively utilized and a high-speed data stream can be further distributed to a plurality of low-speed network interfaces in a balanced manner, thus, the balance degree among all subchannels is improved.

Description

technical field [0001] The invention belongs to the technical field of load balancing, in particular to a load balancing method for a high-speed network. Background technique [0002] In order to improve the security of the network, some security monitoring devices are used to monitor user traffic in real time. With the continuous improvement of network speed, the business volume and data flow continue to grow, making it impossible for a single server to bear. Hardware upgrades for devices will result in waste of resources and high investment costs. In view of this situation, some load balancing methods have emerged as the times require. [0003] The method of load balancing is a cheap, effective and transparent method that can expand the bandwidth of existing network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability. The main principle of load balancing is: the data stream of the high...
