Link aggregation refers to binding a plurality of physical ports together to form a logical port so as to realize load sharing of the ingress/egress traffic in each member port, and the switch determines from which member port a message is sent to the switch at the opposite end according to a port load sharing policy configured by a user. When the exchanger detects that the link of one member port has a fault, the exchanger stops sending the message on the port, recalculates the port for sending the message in the rest links according to the load sharing strategy, and recalculates the port for sending the message again after the fault port is recovered.
Link aggregation is an important technology in terms of increasing link bandwidth, implementing link transmission resiliency and redundancy, and the like. Aggregated links also provide redundancy and fault tolerance if each link of the aggregation follows a different physical path.

As a preferred embodiment, the label issuing unit, the summarizing unit and the counting unit are all realized by an NMU in a master control panel, the sensing unit is realized by a performance processing module in the master control panel, and the acquisition unit is realized by any single panel.
Under a dynamic service switching scene, a single-disk service carries out full deletion and full establishment operation, a performance processing module in a master control disk senses the service deletion and establishment operation, and an NMU dynamically issues a data acquisition label (COUNTID) according to a positioning source object character string.
Preferably, the dynamic issuing of the data acquisition tag according to the character string of the positioning source object includes the following steps:

The LAG port scene is a sub-scene of the dynamic service switching scene, so that the second-level performance statistics can be accurately carried out in the dynamic service switching scene and the LAG port scene.
Example 6
On the basis of embodiment 5, referring to fig. 3, when the TNE in the main control panel notifies the NMU service configuration in the main control panel to delete, the NMU keeps the configuration of the original performance acquisition switch and the second-level acquisition switch unchanged, and does not perform configuration cascade deletion. When the TNE informs the NMU of the establishment of the service configuration, the NMU acquires the corresponding configuration and the data acquisition label key words from the performance switch and sends the key words to the single disk again.
Specifically, referring to fig. 3, the assignment timing of the data acquisition tag (COUNTID) is as follows:
when the TNE in the main control panel informs the NMU service configuration in the main control panel of deletion, the NMU keeps the original performance acquisition switch, the second-level acquisition switch configuration is unchanged, and the configuration cascade deletion is not performed;
when dynamic services are switched, a protocol stack initiates the deletion and establishment operation of the services, an NMU in a master control disk issues a data acquisition label, and a character string of a positioning source object is used as a key word of the data acquisition label. Because the original COUNTID pool is maintained by using the positioning source object KEY as the COUNTID KEY (data acquisition label KEY word), in order to ensure that the COUNTID is kept unchanged during dynamic service switching, a positioning source object character string needs to be used as the COUNTID KEY instead.
When the TNE informs the NMU of the establishment of the service configuration, the NMU acquires the corresponding configuration and the COUNTID KEY value from the performance switch and issues the configuration and the COUNTID KEY value to the single disk again.
Considering that the release of the counttid is not performed for the traffic deletion, it is likely that the counttid pool is full, and for this scenario, the user is required to manually turn off the performance acquisition switch.
As a preferred embodiment, referring to fig. 4, a flow of querying the second-level performance of the network element by the network manager is as follows:
the network management does not sense the outlet disk and the inlet disk, and inquires the second-level performance of the network element according to the service objects, and one network element opens the second-level flow inquiry task of 8 service objects at most.
When the network manager deletes the service configuration, whether the second-level performance switch of the object is started needs to be detected. The second-level performance switch is required to be closed first, and then the service is deleted; failure to turn off the second level performance switch does not affect service deletion.
In the query message sent by the network manager, the disc address needs to be filled with a special disc address (fixed to 0 xFF).
When the device processes the query message issued by the network manager, the converted character string of the positioning source object needs to be cached at the same time, so that the character string of the positioning source object is ensured to be converted only once when the network manager issues the query message, and the conversion efficiency is ensured.
Before the second-level performance is started, time correction must be carried out, and automatic time correction is started.
As a preferred embodiment, referring to fig. 5, the flow of the master control disk processing the service disk response data is as follows:
and the service disk replies the data of the main control disk after receiving the query message sent by the main control disk, and the data of the 0 value is not replied.
The NMU in the master control disk compares the data replied by the service disk based on the service object KEY (KEY word), and when comparing the service object KEY values, the KEY values are converted into corresponding structural bodies and then are compared based on numbers, so that the comparison efficiency is high.
The service disk reply timeout time is set to 5S.
The NMU in the master control disk performs second-level performance accumulation calculation on the designated data acquisition label, the equipment performs one-by-one accumulation according to the sequence of the response performance data of the service disk, and the time point takes the message time of the first response message service disk.
Considering that the number of data values possibly responded by each service disk is different, the minimum number is taken as a reference.
If all service disks of a certain positioning source do not reply the value, the value must also reply to the network manager.
Various modifications and variations of the embodiments of the present invention may be made by those skilled in the art, and they are also within the scope of the present invention, provided they are within the scope of the claims of the present invention and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
