Problems solved by technology

When each node forwards a packet, it forwards it directly based on the tunnel header, and does not read the header content of the original packet that has been encapsulated into the inner payload. Therefore, each node cannot forward the packet based on the priority of the DSCP field. Forwarding packets, unable to implement QoS

Embodiment Construction

[0021] Aiming at the problems existing in the prior art, an implementation method of QoS is proposed in the embodiment of the present invention, the method can be applied to the flow classification node, and the method can be applied to the spine-leaf network, and the flow classification node can be Leaf nodes of the spine-leaf network. In the spine-leaf network, the spine node is connected to the leaf node, and the leaf node is connected to the host, and the host connected to the leaf node can be an independent host, such as a database host, or a host configured with multiple virtual machines, such as Physical hosts, etc., Border nodes are nodes connected to the external core network. Spine nodes and leaf nodes can be connected through an Overlay network. For example, the Overlay network can be a VXLAN network. The processing of other types of Overlay networks is similar to that of the VXLAN network, and will not be described later.

[0022] Such as figure 1 As shown, spine...

Abstract

The present invention provides a QoS (Quality of Service) implementation method and device. The method comprises: a flow classification node obtains the characteristic information of a first message when receiving the first message, and obtain the priority information of the first message according to the characteristic information of the first message; the flow classification node packages a tunnel head including service chain information for the first message, and adds the priority information in the field corresponding to the service chain information of the tunnel head, and a second message is obtained; and the flow classification node send the second message through the priority information to allow the node receiving the second message to send the second message through the priority information carried in the tunnel head. According to the technical scheme of the invention, the QoS is realized, the realization problem is solved of the QoS in an Overlay network, the networking requirement of the Overlay network is satisfied, and the user experience is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for realizing QoS. Background technique [0002] With the rapid development of cloud computing and big data, data center networks are also constantly changing. Various manufacturers have proposed some Overlay (coverage) networks to meet the needs of data centers. The Overlay network is a layer of logical network superimposed on the basis of the Underlay (covered) network (traditional physical network). Extensible Virtual LAN) encapsulation and VXLAN decapsulation. [0003] At present, enterprise user networks are divided into service network, management network, and storage network. These three enterprise user networks are managed by different nodes. The number of nodes is large, and the maintenance workload is heavy. Based on this, there is a demand to carry the service network, management network and storage network through a flat network, an...
