Title: LOAD ADJUSTMENT METHOD, APPARATUS, AND SYSTEM
Abstract:
Provided in the embodiments of the present invention are a load adjustment method, apparatus, and system, relating to the technical field of communications, and being capable of reducing the problems of packet loss or surges due to cross-DC data access. The method comprises: monitoring a load value of each DC amongst a plurality of DC, each DC comprising at least one data block; if the difference between the load value of a first DC and the load value of a second DC is greater than a threshold, determining target data blocks for the first DC to migrate to the second DC, the main DC of the target data blocks all being the first DC, and the backup DC of the target data blocks all being the second DC; in a data block distribution table, switching the main and backup DC relations of the target data blocks such that, after switching, the main DC of the target data blocks is the second DC and the backup DC of the target data blocks is the first DC, the main and backup DC relations of every data block being recorded in the data block distribution table; and sending the data block distribution table to the first DC.
