A queue-level dynamic load sharing method and device

Abstract

The present invention discloses a queue-level dynamic load sharing implementation method and device. The method includes: taking out a port set in a dynamic load sharing group, and reading the port flow state table and all port queues of all ports in the port set The flow state table, according to the forwarding priority of the message, obtains the forwarding queue of the message on each port in the port set, forms a load sharing queue set, and calculates the comprehensive load quantification value of each queue in the load sharing queue set, Select the port corresponding to the queue with the smallest comprehensive load quantization value as the outgoing port for current packet forwarding. The present invention selects the optimal queue for current message forwarding according to the priority of the message to be forwarded, combined with the traffic load of each queue on the port, and ensures that high-priority messages are forwarded through the optimal path when deploying dynamic sharing .

Description

technical field [0001] The present invention relates to a dynamic load sharing technology, in particular to a queue-level dynamic load sharing implementation method and device. Background technique [0002] At present, dynamic load sharing is generally based on the egress port as the scheduling unit. However, when selecting an egress port, the priority of packets to be forwarded cannot be considered. [0003] The port-based dynamic load balancing mentioned above only considers the total rate of ports. Therefore, when deploying dynamic load balancing, it cannot guarantee that high-priority packets will select the optimal available port in the load-balancing port set. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, and provide a method and device for realizing queue-level dynamic load sharing based on message forwarding priority and combining the flow load of each queue on the port. [0005] In order to ac...

[0002] At present, the realization of dynamic load sharing is generally based on the egress port as the scheduling unit. However, when selecting the egress port, the priority of the packets to be forwarded cannot be considered.

[0003] The above-mentioned port-based dynamic load sharing only considers the total rate of ports, so when deploying dynamic load sharing, it cannot guarantee that high-priority packets will select the optimal available port in the load-sharing port set
