[0004] However, there are unavoidable defects in the above method:
[0005] Defect 1. It is relatively simple to use the above method to divide the cache. However, since the cache of each queue is pre-allocated and fixed after allocation, it cannot be automatically adjusted according to the real-time network traffic of each queue. The cache utilization rate is low and lacks self-adaptation perfor

[0056] Based on the first embodiment above, step S13 includes:

[0057] Step S14, reserving a cache space with a preset value in the cache space to be shared, and using the reserved cache space as the cache space to be allocated;

[0058] Step S15 , according to the determined number of queues that need to allocate the cache space to be shared, allocate the cache space to be allocated to each queue that needs to allocate the cache space to be shared.

[0059] Specifically, obtain the size of the cache space to be shared, that is, the size of the shared cache space allocated for multiple queues, for example, it can be 100M, or any other preset shared cache space; Cache space, the preset value can be 10M, or 15M or 30M and other shared cache space set in advance, and the remaining cache space after reservation is used as the cache space to be allocated; allocate the cache to be shared according to the determined needs The number of queues for the space, and allocate the cache s...

Abstract

The embodiments of the present invention provide a method and device for controlling the allocation of a caching space and a computer storage medium. The method comprises: analyzing whether a queue to which a caching space to be shared is required to be allocated exists in each queue or not; when it is determined that the queue to which the caching space to be shared is required to be allocated exists, determining the number of queues to which the caching space to be shared is required to be allocated; and according to the determined number of the queues to which the caching space to be shared is required to be allocated, allocating the caching space to be shared to the queue to which the caching space to be shared is required to be allocated.

Description

technical field [0001] The present invention relates to the field of buffering, in particular to a method and device for allocating and controlling the buffering space of multiple queues. Background technique [0002] With the popularity of the Internet, information exchange and information sharing have become an indispensable part of people's daily life. With the continuous growth of interactive information (data packets) in the network, it will inevitably cause network congestion. Therefore, how to avoid congestion is particularly important. The congestion avoidance mechanism widely used on the Internet is RED (Random Early Discard) mechanism. The key to the RED mechanism is how to effectively use limited cache resources and perform reasonable discarding, so as to avoid congestion and ensure a smooth network. [0003] In the existing multi-queue cache of the RED device using the RED mechanism, the usual ways of allocating the cache include: method 1, which uses the metho...
