Example Embodiment

[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] figure 1 Is the principle block diagram of the priority scheduling method provided by the present invention, such as figure 1 Shown, including:

[0033] Step 101: Set a first buffer queue set and a second buffer queue set for receiving and sending messages in the network workstation, and the first buffer queue set and the second buffer queue set are allocated multiple buffer queues respectively to make different priorities The messages are stored in different buffer queues.

[0034] Step 102: Make the first buffer queue set and the second buffer queue set take turns as the main buffer queue set and the backup buffer queue set.

[0035] In the step 102, by settin...

Abstract

The invention discloses a priority scheduling method and device. The method includes the following steps: a first buffer queue set and a second buffer queue set used for receiving and sending messages are arranged in a network work station; the first buffer queue set and the second buffer queue set are used as a main buffer queue set and a backup buffer queue set in turn respectively; and when the main buffer queue set sends the messages according to a priority sequence, the backup buffer queue set receives and stores the messages. The priority scheduling method and device are capable of ensuring service timelines on the basis of ensuring message priority so that service time delay is reduced reasonably.

Description

technical field [0001] The invention relates to a time division multiplexing system, in particular to a priority scheduling method and device. Background technique [0002] In the case of a certain network bandwidth, in order to meet the service quality requirements of different services, the common method is to assign different priorities to various services, and meet the quality of service of various services through strict priority scheduling to ensure that services with high priority Service flow has less delay and packet loss possibility. [0003] Traditional strict priority scheduling allocates multiple buffer queues for different priorities, and service flows of different priorities enter different priority queues and wait for scheduling. When the transmission conditions are met, the scheduling unit of the network workstation will send the messages in the buffer queue sequentially according to the order of priority. The packets in the buffer queue of the next priori...
