Problems solved by technology
However, in priority mode, using the above method to forward network traffic may seriously waste the bandwidth of the interface. For example, if the aggregation group includes an active interface with a rate of 10 Gigabit and an active interface with a rate of Gigabit , since the network traffic is equally distributed to each active interface in the aggregation group, then the amount of network traffic that can be forwarded by the active interface with a rate of 10 Gigabit will be equal to that of an active interface with a rate of Gigabit The size of the forwarded network traffic is the same, resulting in a serious waste of bandwidth resources

The present application provides a method and device for network traffic distribution. The method includes: selecting the first active interface for sending the message to be sent from the aggregation group according to a preset distribution algorithm, and obtaining the first active interface for sending the message to be sent. A rate identifier corresponding to an active interface; if it is determined according to the rate identifier that the current rate of the first active interface does not reach the limit rate of the first active interface, then the message is sent from the first active interface Send; if it is determined according to the rate identifier that the current rate of the first active interface has reached the limit rate of the first active interface, then other rate identifiers indicate that the current rate of the active interface has not reached the limit rate of the active interface Select a second active interface from the active interfaces corresponding to the value rate, and send the packet through the second active interface. By applying the method of the embodiment of the present application, the bandwidth resource of each active interface in the aggregation group is fully utilized, and the waste of bandwidth resource is reduced.
Description
technical field [0001] The present application relates to the technical field of network communication, and in particular to a method and device for network traffic distribution. Background technique [0002] Port aggregation technology can aggregate multiple physical interfaces together to form a logical aggregation group, and can set multiple interfaces in the aggregation group as active interfaces, so that multiple interfaces can participate in the forwarding of network traffic and increase bandwidth ; and improve the reliability of forwarding network traffic, for example, when the link corresponding to an active interface in the aggregation group fails, the network traffic can still be forwarded through other active interfaces. In the prior art, a priority mode may be used to implement port aggregation. In the priority mode, each interface classified into an aggregation group has a different rate. [0003] In priority mode, when a packet is sent through an aggregation g...
