PACKET FORWARDING IN DATA CENTER NETWORK

摘要

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.

1. A method for forwarding a packet in a data center network, the data center network comprises: at least one server, a virtual Switch (vSwitch) and a Virtual Machine (VM) configured in the server, a physical switch outside of the server and connected with the VM via the vSwitch, the method applied in the physical switch, comprising:
for each 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; after receiving an Ethernet packet sent by the server, searching a Virtual eXtensible Local Area Network (VXLAN) Network Identifier (VNI) according to a source Media Access Control (MAC) address of the Ethernet packet and a Virtual Local Area Network (VLAN) Identifier (ID); and according to the searched VNI, encapsulating the Ethernet packet, obtaining a VXLAN packet, and forwarding the VXLAN packet.
