Problems solved by technology

[0004] 1) The workload of manual operation is heavy; there may be many link aggregation groups in the current network, and the load sharing method of each link aggregation group may be different. It is necessary to modify the hash load method according to the characteristics of the data message. It is necessary to observe whether the load sharing is even
[0005] 2) A default load sharing method cannot guarantee uniform load sharing among members in all link aggregation groups. The variability and complexity of live network packets determine that load sharing cannot be fixed in a certain way
Manually modifying the load sharing method can ensure even load sharing, but the workload is heavy

Embodiment Construction

[0023] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] figure 1 It is a flowchart of a method for selecting a load sharing mode provided by an embodiment of the present invention. Such as figure 1 As shown, this embodiment includes the following steps:

[0025] Step 101, the listening port in the first switch monitors the message sent by the active port in the link aggregation group.

[0026] Preferably, a port outside the link aggregation group in the first switch is designated as the listening port, and packets sent by active ports in the link aggregation group in the first switch are mirrored to the listening port.

Abstract

The invention relates to a load sharing mode selecting method, device and system. A switch monitors message sent by an active port in a link aggregation group; calculates a first bandwidth occupation ratio according to a first message feature of the message and hash algorithm corresponding to a first load sharing mode, then calculates a first weighting factor corresponding to the first load sharing mode according to the first bandwidth occupation ratio; calculates a second bandwidth occupation ratio according to a second message feature of the message and hash algorithm corresponding to a second load sharing mode, then calculates a second weighting factor corresponding to the second load sharing mode according to the second bandwidth occupation ratio; compares the first weighting factor and the second weighting factor and selects a load sharing mode according to the comparison result. The invention solves the dynamic self-adapting balanced load sharing problem.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for selecting a load sharing mode. Background technique [0002] Link aggregation (Link Aggregation) is a method of bundling a group of physical ports together as a logical interface to increase bandwidth, also known as a multi-port load balancing group (Load Sharing Group). By establishing a Link Aggregation Group (Link Aggregation Group) between two devices, it can provide higher communication bandwidth and higher reliability. Communications provide redundant protection. The order of data must be guaranteed after link aggregation groups are introduced. A data stream is a group of data packets with the same source MAC address, destination MAC address, source IP address, and destination IP address. For example, a Telnet or FTP connection between two devices is a stream of data. In order to avoid out-of-order data packets, a data packet forwarding ...
