Data smoothing method and apparatus thereof

Abstract

The invention provides a data smoothing method and an apparatus thereof. The method comprises the following steps: A. distributing version numbers for an item of an upper layer module and an item of a lower layer module in a standby board by a main board, wherein items with same content in the upper layer module and the lower layer module have a same version number; B. when main / standby switching happens, switching the standby board to a new main board which executes a data smoothing process which comprises steps of C, D and E: C. to each item of the upper layer module in the new main board, according to a keyword of the item, searching an item comprising the keyword in a lower layer module of the new main board, if the item is searched, executing the step D, otherwise executing the step E; D. comparing whether the item and the searched item have a same version number or not, if not, using the item and the version number of the item to update the item searched in the lower layer module of the new main board and a corresponding version number, if so, ending processing of the item; E. downloading the item and the version number of the item to the lower layer module of the new main board.

Description

technical field [0001] The invention relates to data communication technology, in particular to a data smoothing method and device. Background technique [0002] Communication equipment in data communication technology is usually required to provide users with reliable and uninterrupted services, and dual-master redundant backup is a commonly used method to increase equipment reliability. Dual master control redundancy backup refers to the replacement of two master control cards with the same function. In the case of failure of the master master control card, the backup master The main control card is used to ensure uninterrupted communication, and the original main control card becomes the backup main control card after failure. This process is usually called active-standby switchover. [0003] In data communication technology, both the active main control board and the standby main control board include upper and lower layers of modules, such as figure 1 As shown, the ac...

Problems solved by technology

[0010] In step 302, whether the content of a table item in the upper module A' and the lower module B' is exactly the same, usually, it is necessary to compare all the fields (that is, all attributes) of the table item, and if the field of the table item (attribute ) are many, then the comparison will be very time-consuming, resulting in a long time for data smoothing after the master-standby switchover, prolonging the data interruption time
