Problems solved by technology

[0004] Embodiments of the present invention provide a cache management method and device, which are used to solve the problem of when a large number of non-hot resources accessed for the first time are pushed out of the cache list by a large number of non-hot resources accessed for the first time due to the small ADC memory cache in the LRU algorithm. Hit rate drop problem

Abstract

The invention provides a cache management method and device and relates to the technical field of communication. The method and device are used for solving the problem that in an LRU algorithm, ADC memory cache is too small, a lot of non-hotspot resources accessed for the first time exclude hotspot resources out of a cache chain table, and accordingly the hit rate is reduced during access of the hotspot resources. The method includes the steps that if it is confirmed that request resource identification of a request resource does not belong to resource identification in the cache chain table and a storage space of a real cache chain table in the cache chain table is full, the request resource identification is inserted to the head of a non-hotspot resource chain table in the real cache chain table, resource identification at the tail end of the original non-hotspot resource chain table is moved to the head of a virtual cache chain table, and a cache resource corresponding to the resource identification at the tail end of the real cache chain table is substituted through the request resource. The method and device are used for resource cache management.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a buffer management method and device. Background technique [0002] Application delivery device (English name: Application Delivery Controller, English abbreviation: ADC) is an upgrade and extension of traditional network load balancing, and is an application delivery platform that integrates various technical means. By properly deploying ADCs, users can further improve service performance and improve service server efficiency. Among them, memory cache is one of the important technologies for ADC to optimize the performance of web page (English name: WEB) application server. The caching system of ADC can replace the hot data that can be cached in the response part of the application server, such as static pages, images, files and other resources, thereby greatly reducing the connection pressure, traffic pressure and performance pressure of the application server....
