Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] VXLAN technology takes the existing three-layer physical network as the underlay network, and builds a virtual two-layer network on it, that is, the overlay network. The overlay network uses the encapsulation technology and the layer-3 forwarding path provided by the underlay network to realize the transfer of tenant layer-2 packets across the layer-3 network and between different sites. For tenants, the Underlay network is transparent, and different sites of the same tenant are like working in a local area network.

[0022] Ethernet Virtual Private Network (Ethernet Virtual Private Network, EVPN) inherits the advantages of VXLAN, and can implement VXLAN Tunnel End Point (VTEP) through Multi Proto...

Abstract

The embodiment of the present application provides a data processing method and a corresponding data processing device, the method is applied to the first edge device of the scalable virtual local area network, including: receiving the target message, determining the target of the target message The network identifier and the target destination address; according to the matching result of the corresponding relationship between the target network identifier and the target destination address and the locally stored network identifier, destination address, and outgoing interface, determine the target outgoing interface corresponding to the target message; through the Send the target packet through the target outbound interface. The embodiment of the present application forwards the message by matching the destination address and the network identifier, avoiding the original forwarding of the message only when the destination address is hit, and solving the problem that multiple virtual machines with the same MAC address but belonging to different VLANs cannot access the same VXLAN question.

Description

technical field [0001] The present application relates to the technical field of computer networks, and in particular to a data processing method and a data processing device. Background technique [0002] With the rapid development of network technology, the scalable Virtual Local Area Network (Virtual eXtensible Local Area Network, VXLAN) can build a large layer-2 network based on the Internet Protocol (Internet Protocol, IP) network to provide layer-2 interconnection for scattered physical sites, and can Provide business isolation for different tenants, making network deployment and maintenance easier. Contents of the invention [0003] The embodiment of the present application provides a data processing method and a corresponding data processing device to implement VXLAN forwarding based on the host address and network identifier, so as to solve the problem of each virtual local area network connected to the same VXLAN in the prior art ( The Virtual Local Area Network...
