Abstract

The present disclosure provides a method and apparatus for forwarding a packet, wherein the method comprising: for each Virtual Machine (VM) in the server, obtaining relevant information of a virtual Network Interface Controller (vNIC) of the VM, and associating the obtained relevant information with a local virtual port, wherein the relevant information includes a Media Access Control (MAC) address of the vNIC, a Virtual eXtensible Local Area Network (VXLAN) Network Identifier (VNI) of the VXLAN where the vNIC is located, and a Virtual Local Area Network (VLAN) Identifier (ID) of a VLAN associated with the VXLAN where the vNIC is located; after receiving an Ethernet packet sent by the server, searching a VNI according to a source MAC address of the Ethernet packet and a VLAN ID; and according to the searched VNI, encapsulating the Ethernet packet, obtaining a VXLAN packet, and forwarding the VXLAN packet.

Description

technical field

[0001] The present application relates to the technical field of network communication, in particular to a message forwarding method and device in a data center network. Background technique

[0002] VXLAN (Virtual eXtensible Local Area Network, Virtual Extended Local Area Network) is a simple mechanism for encapsulating MAC (Media Access Control, Media Access Control) in UDP (User Data Protocol, User Datagram Protocol), which can create (Internet Protocol, Internet Protocol) subnet's virtual Layer 2 subnet. VXLAN can deploy millions of virtual networks in a data center through a 24-bit tenant ID (that is, VXLAN ID or VXLAN network ID (VXLAN Network Identifier or VXLAN Segment ID, VNI)). Moreover, the format of VXLAN packets is easy to implement in hardware, so VXLAN may be more closely integrated with physical network devices in the future.

[0003] Such as figure 1 As shown, the VXLAN message is encapsulated with a VXLAN header in front of the Ethernet f...
