Problems solved by technology
These allocation strategies themselves have very little overhead, and do not need to maintain the state information of the client or server, and the execution efficiency is very high. However, these allocation strategies have weak load balancing capabilities and can only achieve relatively rudimentary system load distribution.
[0007] However, with the emergence of dynamic content on Web sites, the load difference generated by requests is getting larger and larger, and traditional algorithms such as round robin are becoming more and more limited.
And in the cloud computing environment, the Web server cluster adopts virtual technology, and pays more attention to the scalability, flexibility, and distributed efficient computing structure and mode, which contains massive-level dynamic content data, and Web requests are massive-level and have various Due to locality and locality, the load of the Web server cluster is variable and the certainty is low. Therefore, the traditional routing strategy of the Web server cluster system can no longer adapt to the current application requirements, and it is very easy to appear due to the local activity of user access. Local load is too large

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035] A routing method for a Web server cluster, such as figure 1 As shown, the adopted Web server cluster includes a Web request routing system and a response server cluster, the Web request routing system includes a request distributor and a resolution server cluster, and a cache server is arranged between the Web request distributor and the resolution server cluster , the cache server generates and maintains hotspot request records for recording hot web request attribute values, and the hot web request attribute values include Web request name, destination response server address and request count; the parsing server generates and maintains common request records, said Ordinary request records are used to record the attribute values of ordinary web requests. The attribute values of ordinary web requests include the name of the web request, the...

The invention discloses a routing method for a Web server cluster. By setting a cache server, the cache server generates and maintains a hotspot request record, and an analysis server generates and maintains a common request record, and updates and manages the hotspot request record according to the common request record; When a request arrives, the cache server will first match it in the hotspot request record. If a match is found, the web request will be forwarded to the recorded destination response server; if no match is found, the request will be forwarded to the parsing server cluster The destination response server to be parsed and routed to. The present invention distinguishes between hot requests and common requests, distributes requests reasonably, and can greatly enhance the processing capability and response speed of hot requests; at the same time, updates and manages hot request records to maintain validity and adapt to the load Changeable and low-certainty access environment. The invention is suitable for routing management of Web server clusters.
Description
technical field [0001] The invention relates to the technical field of network transmission, in particular to a routing strategy for a Web server cluster. Background technique [0002] Cloud computing refers to the migration of computing loads and applications to the cloud through expansion and virtualization technology to form a large number of distributed computer public resource pools based on the Web Internet. Users access the computer public resource pools through ordinary terminals, such as computers, notebooks, and mobile phones. Perform data calculation, data storage and data acquisition services as needed. The cloud computing model provides available, convenient, and on-demand network access and access to a configurable shared pool of computing resources. Its resources can include networks, servers, storage, application software, and services. These resources can be provided quickly and only need to invest in Little administrative effort, or interaction with servic...
