Problems solved by technology
This algorithm based on the pre-allocation mechanism actually divides the entire cache space and cannot communicate with each other. For each queue, it is obviously an exclusive method. Multiple queues will exclusively share part of the cache resources. It will inevitably lead to a decrease in cache utilization, resulting in frequent packet loss when the entire cache has a large amount of free space.

Embodiment Construction
[0058] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0059] figure 1 It shows the flow of a method for realizing message cache resource sharing in an embodiment of the present invention, and the flow includes the following steps:
[0060] Step S10, preset the state of each queue, and obtain the priority of the queue when a data packet enters the queue; the initial state of each queue can be preset to be empty, and when a new data packet enters the queue, according to the report in the data packet Text descriptor to get the priority of the queue.
[0061] Step S20, adding the queues to the corresponding classification linked list according to the priority; the priority can reflect the importance of the message, and the importance of the message is different with the priority. Assume that there are currently 12 queues 0 to 11. If these queues have data packets entering ...

The invention relates to the technical field of communication, and provides a method for realizing message buffer resource sharing, comprising the following steps: presetting the queue state, and obtaining queue priority when the data packet joins the team; adding the queue to classification list according to the priority; maintaining space occupancy of each queue buffer, initiating the aging indicator when the cache is fully occupied; when receiving the aging indicator, aging treating the queue in each list according to the priority, releasing the space occupied by aging cohort message. The invention also provides a device for realizing message buffer resource sharing. The invention of method and device for realizing message buffer resource sharing is characterized by being capable of improving cache utilization rate, reducing unnecessary lost of data packets, simple parameter configuration, changing the status of smaller cache of each queue caused by number increase of queue, providing a guarantee to support more queues, and truly realizing the cache sharing.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for realizing message buffer resource sharing. Background technique [0002] As we all know, in a variable-length data packet switching network, a congestion avoidance mechanism is an important mechanism for ensuring QoS (Quality of Service, Quality of Service). [0003] In the current congestion avoidance algorithm, the core idea is to pre-allocate a buffer space for each queue, and then expand accordingly based on the configuration parameters calculated by the algorithm, the discarding curve, and the characteristics of the business flow. The algorithm must not only ensure fairness between queues, but also take into account The characteristics of business packets, but most of them do not consider the utilization of cache. This algorithm based on the pre-allocation mechanism actually divides the entire cache space and cannot communicate with ea...
