Embodiment Construction

[0045] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0047] Embodiments of the present invention provide a load adjustment method, which can be applied to such as figure 2 In the load adjustment system 100 shown, the load adjustment system 100 includes N DCs 21 and a GSC (Global Serv...

Abstract

The embodiment of the invention provides a load adjustment method, device and system and relates to the technical field of communication. The problem can be solved that packet loss or surge is causedby cross-DC data access. The method comprises the steps that a load value of each DC in multiple DCs is monitored, wherein each DC comprises one or more data blocks; if difference values between the load values of first DCs and the load values of second DCs are larger than a threshold value, target data blocks which are immigrated toward the second DCs by the first DCs are determined, wherein allmain DCs of the target data blocks are the first DCs, and all backup DCs of the target data blocks are the second DCs; main-backup DC relations of the target data blocks in a data block distribution table are reversed, wherein the reversed main DCs of the main data blocks are the second DCs, the backup DCs of the target data blocks are the first DCs, and the main-backup DC relation of each data block is recorded in the data block distribution table; the data block distribution table is sent to the first DCs.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a load adjustment method, device and system. Background technique [0002] Generally, multiple DCs (Data Centers) will be set in an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network or LTE (LongTerm Evolution, long-term evolution) network, and multiple Load balancing between DCs. [0003] Specifically, each DC can act as the primary DC, and back up the business data stored in itself in any other backup DC, for example, if figure 1 As shown, the business data in DC1 can be backed up in DC2, the business data in DC2 can be backed up in DC3, and the business data in DC3 can be backed up in DC1. In this way, when GTM1 in DC1 detects that its load exceeds a certain When the threshold is reached, GTM1 will send the address of any other DC, for example, the address of DC3, to the peer NE. Afterwards, the peer NE will interact with DC3 according to the...
