Abstract

The invention discloses a network equipment load balancing method and device based on a CLOS architecture. The method comprises the steps: detecting whether the panel bandwidth is equal to the backboard bandwidth or not, wherein the panel bandwidth is the sum of bandwidths of all ports of at least one service board card, and the backboard bandwidth is the sum of bandwidths provided by at least oneswitching matrix board card; if the panel bandwidth is equal to the backboard bandwidth, selecting a first preset load balancing algorithm to perform load balancing; if the panel bandwidth is not equal to the backboard bandwidth, selecting a second preset load balancing algorithm to perform load balancing. The second preset load balancing algorithm is a load balancing algorithm based on message content, and the first load balancing algorithm is a load balancing algorithm based on a source port. According to the embodiment of the invention, in the operation process of the network equipment, the load balancing algorithm is adaptively selected according to the backboard bandwidth and the panel bandwidth, so the accuracy of algorithm selection is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for balancing network equipment loads based on CLOS architecture. Background technique [0002] CLOS architecture refers to the network switching structure invented by Charles Clos, which can realize the separation of control and forwarding hardware of network equipment. All control functions of network equipment are implemented on the main control board, and the forwarding function is implemented on the switch matrix board. In the CLOS architecture, all data traffic on the service board (line card) is forwarded through the switch matrix board instead of the main control board. [0003] The service boards (line cards) of the CLOS architecture and the switch matrix boards are interconnected through the backplane ports. The switch matrix board is mainly responsible for data forwarding between line cards. In order to reduce the pressure on the line cards ...
