Abstract

The invention relates to a method for realizing the synchronous data between the server and the client in DNS mode, which comprises: A, server judging if there is data to be refreshed, if there is, the server sends a information that the data has been refreshed to the client terminal, and uses its field information to mark said information; B, the client terminal according to received field information to refresh the record in the local memory, therefore, the client terminal can according to itself demand to delete relative record in the memory or request the refreshed record to the server again when said record is needed. The invention also allows client terminal to directly refresh the record in the memory for next usage according to the refresh record carried in the inform information of server. The invention can flexibly and simply keep synchronous data between the server and the client to conform the normal operation of client terminal.

Description

technical field

[0001] The invention relates to domain name system (DNS) mechanism maintenance technology, in particular to a method for realizing synchronization of associated resource data between a server and a client in the DNS mechanism. Background technique

[0002] At present, in the DNS mechanism, data synchronization between servers is realized through the Notify message stipulated in the protocol. For example, after the domain file on the master server is updated, the master server will actively send a Notify message to the slave server to inform the slave server that Domain files have been updated. This keeps the data in sync between the master server and the slave server.

[0003] However, there is no such synchronization mechanism between the server and the client to ensure that the data between the server and the client is consistent. The data mentioned here refers to the identification information negotiated between the server and the client. The terminal re...
