Abstract

The invention discloses an LACP load balancing method, device and system in the field of data communications. By adoption of flow sampling technology, the method comprises the following steps of making an real-time statistical analysis on the current service flow of at least one message type of the aggregation group, and determining the optimal load balancing mode of the current service flow of atleast one message type of the aggregation group, thereby realizing the purpose of dynamically adjusting the load balancing mode of the aggregation group according to the message type, and having better flexibility and practicability.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method, device and system for LACP load balancing. Background technique [0002] Link Aggregation Control Protocol (LACP for short) is a technology for bundling multiple physical ports into one logical port. This technology can treat multiple physical links as a single logical connection, allowing two network devices to be connected in parallel through multiple ports and transmit data at the same time to provide higher bandwidth and throughput and improve system stability sex. [0003] With the rapid development of network communication technology, LACP technology has been more and more applied in the process of data transmission. Theoretically, link bandwidth should be doubled after link aggregation. For example, after four member links are aggregated, the bandwidth can be quadrupled. However, this effect cannot be achieved in actual use, because in a complex network envir...
