Problems solved by technology

[0006] 3. When the client cannot obtain domain name resolution in the local domain name cache, the client needs to initiate a domain name resolution request to the domain name resolution server;
Therefore, when a specific domain name resource record changes, the domain name resource records cached in each domain name resolution server have not been updated in time, which will cause domain name resolution errors and cause business unavailability

[0071] In the first embodiment of the present invention, a method for centralized management and control of domain name resource record cache, such as figure 2 As shown, the process performed on the domain name resolution server side includes the following specific steps:

[0072] Step S201, during the domain name resolution process, the domain name resolution server caches the domain name resource records provided by the domain name server. Wherein, the domain name server includes: an authoritative domain name server, and the authoritative server is a root node of a group of authorized domain name servers.

[0073] Step S202, after caching the domain name resource record provided by the domain name server, send a corresponding cache announcement message to the domain name resource record cache manager, so that the domain name resource record cache manager can update the domain name resource record cache manager according to the received cache announcement message The domain...

[0081] In the second embodiment of the present invention, a method for centralized management and control of domain name resource record cache, such as image 3 As shown in , the processes executed on the domain name resource record cache manager side include:

[0082] Step S301, receiving a caching declaration message, which is sent by the domain name resolution server to the domain name resource record cache manager after caching the domain name resource records provided by the domain name server.

[0083] Specifically, the domain name resource record provided by the domain name server carries the following information:

[0084] Cache announcement control information, used for the domain name resolution server to determine whether to perform cache announcement based on the cache announcement control information; and,

[0085] The address identification information is used for the domain name resolution server to send a cache announcement message to the domain name resource ...

[0090] In the third embodiment of the present invention, a method for centralized management and control of domain name resource record cache, the process executed on the domain name server side includes:

[0091] Based on the domain name resolution request of the domain name resolution server, provide corresponding domain name resource records to the domain name resolution server to assist the domain name resource record cache manager to manage and control the domain name resource records cached in the domain name resolution server and provided by the domain name server;

[0092] The domain name resource record carries:

[0093] Cache announcement control information, used for the domain name resolution server to determine whether cache announcement is required based on the cache announcement control information;

[0094]The address identification information is used for the domain name resolution server to send a cache announcement message to the domain name resource record ...

Abstract

The invention provides a centralized management and control method and device for domain name resource record cache and relevant equipment. A domain name resource record cache manager is added; a new type of domain name resource record is attached when a domain name server provides domain name resource records for a domain name resolution server; the new type of domain name resource record carries cache declaration control information and address identification information; and meanwhile, a domain name resolution processing process is modified, so that a declaration can be made to the centralized domain name resource record cache manager when the domain name resolution server caches the domain name resource records in a domain name resolution process, thereby realizing centralized management and control of the cache of the domain name resource records. Through adoption of the method, the device and the relevant equipment, a large quantity of unauthorized domain name resource records cached in resolution servers in a network can be managed and controlled; the availability of Internet services is improved effectively; and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of domain name system in communication network, in particular to a centralized management and control method, device and related equipment of domain name resource record cache. Background technique [0002] In the prior art, domain name resolution technology is a fundamental technology of the Internet. It provides a mutual mapping relationship between domain name information and Internet Protocol (IP) address information, so that users do not need to memorize complex IP address information when using the Internet, but only need to record simple domain name information, greatly Promoted the development of the Internet. [0003] The existing domain name resolution and domain name cache processing is a complicated process. Now take the client’s need to access www.zte.com as an example to describe the specific domain name resolution and domain name cache processing in detail. figure 1 is a signaling fl...
