Problems solved by technology

[0004] That is to say, when DCNFabric uses VXLAN as the service bearer technology, both the leaf switch and the spine switch implement ECMP forwarding directly based on the destination address in the outer IP header of the VXLAN packet, and cannot implement the specified path forwarding of the packet in DCNFabric.

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] figure 1 is a schematic flowchart of a method 100 for forwarding packets according to an embodiment of the present invention. The method 100 is applied in the DN CFabric supporting the VXLAN technology. Such as figure 1 As shown, the method 100 may include the following steps.

[0029] 110. The first node acquires the packet.

[0030] The first node may be a leaf switch or a spine switch in the DNCFabric. The first node may directly receive the o...

Abstract

The invention provides a method and a switch for forwarding a message. The method for forwarding the message comprises the steps that: a first node obtains the message; the first node determines a forwarding path of the message when the message needs to be forwarded through a prescribed path; the first node determines at least one output interface according to the forwarding path; and the first node forwards the message to a second node through one of the at least one output interface. According to the embodiments of the invention, when the message is determined to be forwarded through the prescribed path, the forwarding path of the message is determined, the output interface is determined according to the forwarding path, and then the message is forwarded through the output interface, so that message forwarding through the prescribed path is realized in DCN Fabric.

Description

technical field [0001] The invention relates to the communication field, in particular to a message forwarding method and a switch. Background technique [0002] At present, the data center network (English: DateCenterNetwork, abbreviation: DCN) mainly uses a flat, non-blocking networking method to build DCNFabric. In DCNFabric, each leaf (leaf) switch can be connected to other nodes through the backbone (spine) switch. leaf switch. In order to meet the requirements of cloud computing and data center virtualization, the data center network needs to support multi-tenants, and each tenant is required to only access its own dedicated network and cannot access the networks of other tenants. Virtual Extensible Local Area Network (English: VirtualExtensibleLocalAreaNetwork, abbreviation: VXLAN) technology is a technology proposed by the Internet Engineering Task Force (English: InternetEngineeringTaskForce, abbreviation: IETF), which distinguishes the traffic of different tenants...
