METHOD, DEVICE AND SYSTEM FOR PROCESSING DNS CACHE INFORMATION

摘要

Provided are a DNS cache information processing method, device and system. The method comprises: upon reception of a client request, resolving and obtaining domain name information requested by the client; querying in a database a data structure corresponding to the domain name information; when finding the data structure, acquiring read lock information corresponding to the data structure, the read lock information being permission information allowing performing a read operation of the cache information stored in the data structure; reading the cache information in the data structure by using the permission of the read lock information, and transmitting the read cache information to a sender requested by the client. The embodiment of the present invention can improve caching speed and cache information throughput, improving the flexibility of cache information, and enhancing the quality of stored information.
