Embodiment Construction

[0038] In order to solve the problem of packet loss in the prior art caused by migration of a certain VXLANIPGW, the following embodiments of the present application provide an SDN-based gateway migration processing method and a device to which the method can be applied.

[0039] The method and device in the embodiment of the present application are suitable for such as figure 1 In the SDN-based network architecture shown. Such as figure 1 As shown, SDN includes: controller ( figure 1 not shown in ), server, VTEP and N (N is a natural number not less than 2) VXLANIPGW ( figure 1 Take 2 VXLANIPGWs as an example), where the server includes: VM and its connected vSwitch. VTEP establishes a VXLAN tunnel with VXLANIPGW through the existing network to form a VXLAN network; the server is connected to VXLANIPGW through VTEP; one end of VXLANIPGW is connected to the VXLAN network, and the other end is connected to a traditional layer-3 network (that is, a non-virtualized network), a...

Abstract

The invention discloses a gateway migration processing method and a gateway migration processing device based on a software defined network, wherein the gateway migration processing method is applied on a first virtual extensible local area network IP gateway (VXLAN IP GW) to be migrated in at least two VXLAN IP GWs. The gateway migration processing method comprises the steps of reducing the priority of a router which carries IP address of a VXLAN tunneling end point (VTEP) and transmitting the priority to the VTEP, reducing the priority of a static router to a virtual machine (VM) and transmitting the priority to exchange equipment of a non-virtual network; wherein before priority reduction of the router on the first VXLAN IP GW, the priorities of routers which carry the IP address of the VTEP on at least two VXLAN IP GWs are same, and the priorities of static routers from at least two VXLAN IP GWs to the VM are same; and when a controller monitors no data flow between the VM and the exchange equipment on the first VXLAN IP GW, performing a migration action.

Description

technical field [0001] The present application relates to the technical field of virtualization, and in particular to an SDN-based gateway migration processing method and device. Background technique [0002] At present, the internal layout of large-scale data centers adopts the layout of large two-layer network. The existing large two-layer technology is mainly overlay (overlay) technology. The large two-layer network needs to communicate with the existing traditional three-layer network. In this way, it is necessary to set up a gateway device (Gateway) supporting Layer 2 and Layer 3 forwarding on the edge of SDN (Software Defined Network, Software Defined Network) to communicate with the external traditional Layer 3 network. [0003] Such as figure 1 As shown, SDN includes: controller (Controller, figure 1 Not shown in), server, VTEP (VXLANTunnelingEndPoint, VXLAN tunnel terminal) and VXLAN (VirtualeXtensibleLocalAreaNetwork, virtual extensible local area network) IP (In...
