Embodiment 1

[0094] An embodiment of the present invention provides a data processing method, which is applied to a VAGW node. Figure 5 It is a schematic flow diagram of a data processing method in Embodiment 1 of the present invention; as Figure 5 As shown, the method includes:

[0095] Step 101: the VAGW node establishes tunnel connections with multiple VXLAN tunnel nodes VTEP through the SDN controller.

[0096] Step 102: Through the established tunnel connection, the VAGW node receives the message of the first VTEP, and forwards the message to the corresponding second VTEP node.

[0097] In this embodiment, the VAGW node is a newly added node, so that no tunnel connection is established between all VTEPs, but each VTEP establishes a tunnel connection with the VAGW node.

[0098] specific, Figure 6 It is a schematic diagram of the composition of the VAGW node of the embodiment of the present invention; as Figure 6As shown, the VAGW node includes a physical port; the VAGW node is...

Embodiment 2

[0104] The embodiment of the present invention also provides a data processing method, which is applied to the VTEP. Figure 6 It is a schematic flow chart of the data processing method of the second embodiment of the present invention; as Figure 6 As shown, the method includes:

[0105] Step 201: When the first VTEP receives the packet of the first virtual machine, it encapsulates the packet based on the forwarding policy sent by the SDN controller; the encapsulated packet carries destination information.

[0106] Step 202: The first VTEP sends a message to the VAGW node based on the tunnel connection with the VAGW node.

[0107] As an implementation manner, before the first VTEP receives the message of the first virtual machine, the method further includes: the first VTEP perceives the mount action of the first virtual machine, and generates the first virtual machine forwarding information, sending the forwarding information of the first virtual machine to the SDN control...

Embodiment 3

[0111] The embodiment of the present invention also provides a data processing method, which is applied to an SDN controller. Figure 7 It is a schematic flow chart of the data processing method of the third embodiment of the present invention; as Figure 7 As shown, the method includes:

[0112] Step 301: the SDN controller controls the establishment of tunnel connections between the VAGW node and multiple VTEPs.

[0113] Step 302: When the SDN controller receives the first packet of the first VTEP, generate a forwarding policy, and send the forwarding policy to the first VTEP, so that the first VTEP sends the forwarding policy based on the forwarding policy message.

[0114] In this embodiment, the tunnel established between the VAGW node and multiple VTEPs is connected to the SDN controller for management and control, and all VTEPs and VAGW nodes are controlled by the SDN controller, and the control protocol is realized by the combination of Openflow / OVSDB. Wherein, Open...

Abstract

The embodiment of the invention discloses a data processing method, a system and a node. The method comprises the following steps: a virtual extensible local area network (VXLAN) aggregation gateway (VAGW) node establishes the tunnel connection with multiple VXLAN tunnel nodes VTEP through the software-defined network (SDN) controller; the VAGW node receives a message of the first VTEP through the established tunnel connection, and the message is forwarded to the corresponding second VTEP node.

Description

technical field [0001] The present invention relates to data service technology, in particular to a data processing method, system and node. Background technique [0002] A virtual extensible local area network (VXLAN, Virtual eXtensible Local Area Network) is a mainstream technology in the Overlay technology. There are two ways to use VXLAN in the data center, host Overlay and network Overlay. Host Overlay supports VXLAN in the vSwitch in each host virtual machine monitor (Hypervisor), and network Overlay supports VXLAN on data center network devices. [0003] The VXLAN tunnel node (VTEP, VXLAN Tunneling End Point), the vSwitch of the host Overlay, and the VXLAN device starting from the network Overlay are all VTEPs. [0004] In the existing VXLAN solution, all VTEPs in a Layer 2 domain need to establish tunnel connections to ensure Layer 2 network connectivity. Therefore, under the worst conditions, this connection relationship is of N*(N-1) scale, specifically as figu...
