Problems solved by technology

VXLAN's QoS (Quality of Service, Quality of Service) is based on the IP layer. IP forwarding is a best-effort forwarding mechanism. When the network is congested, data packets may be discarded; IP forwarding cannot meet bandwidth requirements; IP QoS is distributed The implementation mechanism cannot meet the end-to-end differential service requirements

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0038] The inventors have discovered the existing technical problems in implementing differentiated services for VXLAN services:

[0039]At present, the existing VXLAN differential service technology needs to expand the VXLAN header field, but the intermediate device between the two VTEP (VXLAN Tunnel Endpoints, VXLAN tunnel endpoints, which can perform VXLAN encapsulation and decapsulation) nodes connecting the data center , is a traditional network device that forwards based on IP, does not perceive VXLAN information, and does not support VXLAN extension fields. If this technology is used, al...

Abstract

The present invention provides a VXLAN service differential implementation method and VTEP and PE, wherein the method includes: the first source VTEP receives a message from a user, maps the message into a VXLAN tunnel, and sends the message to the MPLS-VNI according to the VXLAN network identifier VNI The first mapping relationship of the TE tunnel, and the pre-configured service priority and bandwidth for the user corresponding to the VNI, sends the packet through the MPLS‑TE tunnel; the first destination VTEP receives the packet and sends the packet to the VNI corresponding user. The above technical solution realizes the differentiated service of the VXLAN service.

Description

technical field [0001] The present invention relates to the technical field of VXLAN, in particular to a method for realizing difference of VXLAN service, VTEP and PE. Background technique [0002] VXLAN (virtual eXtensible LAN, scalable virtual local area network) tunnel is to encapsulate layer-2 data packets into a layer-3 network, so as to realize large-scale layer-2 communication across data centers. VXLAN's QoS (Quality of Service) is based on the IP layer. IP forwarding is a best-effort forwarding mechanism. When the network is congested, data packets may be discarded; IP forwarding cannot meet bandwidth requirements; IP QoS is distributed The implementation mechanism cannot meet the end-to-end differential service requirements. Contents of the invention [0003] In the first aspect, an embodiment of the present invention provides a method for implementing differential VXLAN services, to implement differential services for VXLAN services. The method includes: [00...
