8. The apparatus according to claim 6, wherein the detecting unit is specifically configured to, if the first bridging link fails, collect MAC addresses of wired terminals under wired ports of non-root-bridge APs, construct a broadcast packet including the MAC addresses, and send the broadcast packet through an available bridging link to a higher access switch connected to a root-bridge AP corresponding to the available bridging link to update a MAC address table of the higher access switch, so as to evenly distribute uplink packets of the first bridging link to the available bridging link.
9. The apparatus according to claim 8, wherein the detecting unit is specifically configured to collect MAC addresses of the wired terminals under the wired port of the non-root bridge AP if the first bridge link is down; according to a balancing algorithm, a MAC address list which needs to be guided to other available bridging links is obtained by screening from the collected MAC addresses; and constructing a broadcast message comprising the MAC address in the MAC address list, sending the broadcast message to a superior access switch connected with a root bridge AP corresponding to the available bridging link through other available bridging links, updating an MAC address table of the superior access switch, and uniformly dispersing the uplink message of the first bridging link to the available bridging link.
10. The apparatus of claim 6, further comprising: the MAC updating unit is used for collecting the MAC address of the wired terminal under the wired port of the non-root bridge AP if the second bridge link is on line; according to a balancing algorithm, screening out an MAC address list needing to be guided to a second bridging link from the collected MAC addresses; and constructing a broadcast message comprising the MAC address in the MAC address list, and sending the broadcast message to a superior access switch connected with a root bridge AP corresponding to the available bridging link through the available bridging link, so that the superior access switch updates the MAC address in the MAC address list to the MAC address list of the superior access switch, and the uplink message of the available bridging link is uniformly dispersed to the second bridging link.
11. An electronic device, comprising at least one processing unit and at least one memory unit, wherein the memory unit stores a computer program that, when executed by the processing unit, causes the processing unit to perform the steps of the method according to any one of claims 1 to 5.
12. A computer-readable medium, in which a computer program executable by a computing device is stored, which program, when run on the computing device, causes the computing device to perform the steps of the method according to any one of claims 1 to 5.
