Caching management method and caching management system

Abstract

The invention discloses a buffer management method which comprises the following steps: when a buffer address is applied, the applied buffer address is marked as applied state; when cycle timing time which is determined according to maximum application time of the buffer address is reached each time by time keeping, the buffer address in the applied state is released. The invention also provides a buffer management system. By utilization of the invention, all applied buffer addresses can be initiatively released in definite time, and all the applied buffer addresses are guaranteed to be able to be withdrawn, thereby buffer leakage is reduced.

Description

technical field [0001] The invention relates to cache technology, in particular to a cache management method and a cache management system. Background technique [0002] FIG. 1 is a schematic structural diagram of an existing caching system. As shown in FIG. 1 , the system includes an address request unit 110 , a cache management unit 120 , a cache unit 130 and an address release unit 140 . Wherein, after the address request unit 110 receives the message to be cached, it proposes an address application request to the cache management unit 120, and after applying for the cache address, saves the message to be cached on the cache address in the cache unit 130, and sends the cached message to the address release unit 130. 140 sends the cached message-related information including the cached address; the address release unit 140 reads the corresponding message from the cache unit 130 according to the cached address in the cached message-related information and outputs it, and s...

Problems solved by technology

[0004] In practical applications, the address release unit 140 may fail to receive the cached message related information sent by the address requesting unit 110 for some reason, and the cached message will always be stored in the cache unit 130. The occupied cache address cannot be released normally

Then the cache address occupied by the message will not be reclaimed permanently, resulting in a reduction in the number of cache addresses. This situation is called a cache leak

When there are many cache leaks, the cache capacity in the system will not be able to meet the actual cache needs, resulting in a decrease in the performance of the cache system
