Embodiment Construction

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0038] A method for improving the forwarding performance of delay-sensitive traffic disclosed in the present invention dynamically adjusts the priorities of mouse traffic and elephant traffic, and further configures different scheduling strategies for the egress queues where mouse traffic and elephant traffic are located, so that Mouse flows that are more sensitive to network delay are prioritized for scheduling.

[0039] Such as figure 1 As shown, a method for improving delay-sensitive traffic forwarding performance disclosed by the present invention includes the following steps:

[0040] Step S100, receiving the message and identifying the elephant flow and the mouse flow;

[0041] Specifically, in the data center network, most of them are mouse flows, which occupy a small amount ...

Abstract

The invention discloses a method and a device for improving delay sensitive flow forwarding performance, and belongs to the technical field of network communication. The method comprises the followingsteps: receiving a message and identifying the message as elephant flow or mouse flow; dynamically adjusting the priorities of the mouse flow and the elephant flow in the forwarding chip, so that thepriority of the mouse flow in the forwarding chip is higher than that of the elephant flow, and the mouse flow and the elephant flow further entering different outlet queues; and scheduling the exitqueue where the mouse flow is located through a priority scheduling algorithm, and scheduling the exit queue where the elephant flow is located through a polling scheduling algorithm. According to themethod, the mouse flow sensitive to the time delay and the elephant flow insensitive to the time delay are identified, the priorities of the mouse flow and the elephant flow are dynamically adjusted,and different scheduling strategies are configured, so that the forwarding performance of the time delay sensitive flow can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a device for improving the forwarding performance of delay-sensitive traffic. Background technique [0002] With the rapid development of applications and services such as big data, cloud computing, and artificial intelligence, the data traffic in the data center network is also increasing. In the data center network, there are usually two kinds of traffic: mouse flow and elephant flow. Among them, the mouse flow refers to the data flow that occupies a small part of the bandwidth of the data center network, such as data flows such as requests and responses. Sensitive; elephant flow refers to the data flow that occupies most of the bandwidth of the data center network, such as data flow such as download and video, which is relatively insensitive to network delay. [0003] In the data center network, the mouse flow has high requirements on the network de...
