Embodiment Construction

[0064] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0065] figure 1 It is a schematic diagram of a topology structure of a data center provided by an embodiment of the present application. A switch 10, a terminal device 20 and a server cluster 30 including N servers are deployed in the data center, which are respectively S1, S2, S3, S4...SN. Wherein, the upstream port of the switch 10 is respectively...

Abstract

The invention provides a data transmission method, a switch and a data centre, wherein the method comprises the steps of: in a current transmission cycle, identifying small-flow messages from a data flow requested from a server cluster by terminal equipment, wherein the small-flow messages are messages, the byte numbers of which are less than an appointed byte threshold value; removing duplications of the small-flow messages according to the routing message of the messages, so that the small-flow messages from different routing information are obtained; and, prior to non-small-flow messages inthe data flow, sending the small-flow messages from different routing information to the terminal equipment. By means of the method provided by the invention, the packet loss probability of the small-flow messages can be effectively reduced; and the network delay is reduced.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a data transmission method, a switch and a data center. Background technique [0002] A data center is a network of specific devices for global collaboration, which is used to transmit, accelerate, display, calculate, and store data information on the Internet network infrastructure. With the continuous development of data center technology, the load of the data center is getting heavier, especially in the data center adopting Transmission Control Protocol (Transmission Control Protocol, TCP). [0003] In a data center using TCP, a terminal device is connected to multiple servers through a switch, and requests data from multiple servers through the switch, and the switch obtains data from multiple servers according to the data request of the terminal device and sends the obtained data to the terminal equipment. During the process of the terminal device requesting...
