Abstract

The application discloses a cache management method and device, which relate to the technical field of communication networks and can solve the technical problem of poor cache reliability. The device includes a master management unit and at least two slave management units, each slave management unit is used to process a type of message, and the method includes: if the total amount of free cache is less than or equal to a first threshold, the master management unit According to the weight of each slave management unit, assign the idle cache to each slave management unit, and the free cache capacity allocated to each slave management unit is positively related to its weight; or when the cache capacity used by the slave management unit is greater than or When it is equal to the third threshold, if the total amount of free cache is greater than or equal to the second threshold, the master management unit increases the cache capacity of the slave management unit, temporarily increases the ability of the slave management unit to occupy the shared cache, and reduces at least one other slave management unit. The cache capacity of the unit, where increased cache capacity is equal to decreased cache capacity. The solution provided by this application is suitable for managing shared cache.

Description

technical field [0001] The present application relates to the technical field of data communication, and in particular to a method and device for managing cache. Background technique [0002] The rapid development of communication technology has greatly facilitated the communication between people, and also created a huge demand for data transmission, which requires communication devices such as routers to have higher data transmission capabilities. It should be noted that when a router sends and receives packets, it needs to perform processing such as encapsulation / decapsulation on the received packets before sending them out. It can be seen that the router also needs to have the ability to store received but unsent packets. ability. [0003] In order to facilitate routers to process various types of packets such as ordinary packets, encrypted packets, flow control packets, and protocol packets, the router usually allocates buffers to different types of packets during the ...
