Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for switching a link aggregation scheme.
Background
With the development of communication technology, the communication volume between network devices is larger and larger, and the traffic volume of each port of the network device is also larger accordingly. Therefore, a link aggregation method is required to achieve a reasonable load sharing effect of traffic between multiple ports of the network device, that is, multiple physical ports of the network device are aggregated together to form a logical port, so as to implement load sharing of the throughput of the outgoing/incoming traffic at each member port.
The common link aggregation method fixedly supports one or more aggregation schemes, when one aggregation scheme is used, other aggregation schemes cannot be switched, and for multiple aggregation schemes, switching between aggregation schemes is realized by only updating configuration of one table entry. When the message is transmitted through the aggregation group selected by the table entry, since the message is still transmitted by using the table entry when the table entry is configured and updated, the subsequent message may still be transmitted by using the original aggregation group or by selecting the wrong aggregation group. Therefore, the general method of switching the link aggregation scheme may cause a large number of routing errors.
