Problems solved by technology

[0005] (1) The discarding threshold or back pressure revocation threshold of each queue is set to the maximum cache depth, that is, each queue can occupy all cache resources, which can ensure that each queue has the maximum traffic burst absorption capacity; but when When a queue is congested, it will affect the normal input and output of other queues, and even cause the data flow of other queues to be interrupted
[0006] (2) The discarding threshold or back pressure revocation threshold of each queue is set to a fixed value, and the sum of all queue thresholds does not exceed the total cache resource size of the port, which can ensure that each queue has resources available and will not be One or several queues occupy all buffer resources; but when a queue is congested and other queues are idle, the congested queue may lose packets, and other free buffer resources of the port cannot be effectively utilized

[0034] The first embodiment of the present invention records a port congestion management method, figure 2 It is a flow chart of the port congestion management method of the embodiment of the present invention, such as figure 2 As shown, the method includes:

[0035] Step 201: Detect the size of the remaining buffer resources of the port, and the remaining buffer resources of the port are used to indicate the buffer resources except the occupied buffer resources among all the buffer resources of the port;

[0036] It can be understood that the size of all cache resources in the port can be predetermined, and the size of the cache resources occupied in the port can be detected in real time by a device such as a processor, so that the size of the remaining cache resources of the port can be determined .

[0037] Step 202: When the remaining buffer resources of the port increase, control to increase the congestion discarding threshold of each queue of the port; when the remai...

Abstract

An embodiment of the invention provides a port congestion management method. The method comprises the steps of detecting the size of remaining cache resources of a port, wherein the remaining cache resources of the port are used for representing cache resources except occupied cache resources in all cache resources of the port; when the remaining cache resources of the port are added, increasing acongestion discarding threshold of each queue of the port by control; reducing the congestion discarding threshold of each queue of the port by control when the remaining cache resources of the portare reduced; and according to the changed congestion discarding threshold of each queue, processing messages in each queue. Embodiments of the invention further disclose a port congestion management apparatus and device, and a computer readable storage medium.

Description

technical field [0001] The present invention relates to computer communication technology, in particular to a port congestion management method, device, equipment and computer-readable storage medium. Background technique [0002] Congestion management is a very important technical means in the switching access (Switching Access, hereinafter referred to as SA) chip; the SA chip receives a large number of message slices from the switching network, and caches these messages in different ways according to a certain method. In the queue, the messages in different queues are scheduled and output according to certain scheduling rules; when the message traffic bursts or the data flow is shaped, that is, when the input rate of the queue is greater than the scheduled output rate of the queue, the queue depth will be accumulated. Form buffer congestion. At this time, a congestion management strategy is needed to back-press or discard the incoming packets to avoid system hang-up. [...
