Embodiment Construction

[0038] In order to solve the packet loss problem existing in the prior art due to the migration of a certain VXLAN IP GW, an SDN-based gateway migration processing method and a device that can apply the method are provided in the following embodiments of the present application .

[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) VXLANIP GWs ( figure 1 Take 2 VXLAN IP GWs as an example), where the server includes: VM and its connected vSwitch. VTEP establishes a VXLAN tunnel with the VXLAN IP GW through the existing network to form a VXLAN network; the server is connected to the VXLAN IP GW through the VTEP; one end of the VXLAN IP GW is connected to the VXLAN network, and the other end is connected to a traditional layer-3 network (th...

Abstract

The present application discloses a software-defined network-based gateway migration processing method and device, wherein the method is applied to the first VXLAN IP GW to be migrated among at least two VXLAN IP GWs, the method includes: After reducing the priority of the route to the VTEP, the priority of the static route to the VM is reduced and then released to the switching device of the non-virtualized network; among them, before the priority of the route on the first VXLAN IP GW is reduced, at least The priority of the route carrying the VTEP IP address on the two VXLAN IP GWs is the same, and the priority of at least two static routes from the VXLAN IP GW to the VM is the same; when the controller detects that there are no VMs and switching devices on the first VXLAN IP GW When the data flow between, execute the 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 the SDN (Software Defined Network, Software Defined Network) to communicate with the external traditional Layer 3 network. [0003] like figure 1 As shown, SDN includes: controller (Controller, figure 1 Not shown in), server, VTEP (VXLANTunneling End Point, VXLAN tunnel terminal) and VXLAN (Virtual eXtensible Local AreaNetwork, virtual extensible local area network) ...
