Problems solved by technology

When the delay time of the VXLAN tunnel between the destination VTEP device selected by the SDN controller and the source VTEP device is very long, it takes a long time for the data to be successfully migrated to the destination VTEP device, and the data migration cannot be completed in the shortest possible time

Embodiment Construction

[0043] Aiming at the problems existing in the prior art, a data migration method is proposed in the embodiment of the present invention, which can be applied to the SDN based on the VXLAN network to figure 1 It is a schematic diagram of the application scenario of the embodiment of the present invention. The user servers connected to each VTEP device will be evenly distributed, and will be smoothly migrated between different VTEP devices according to the actual load situation. exist figure 1 , only the user server 1 attached to VTEP device 1 is displayed, and other user servers are not in the figure 1 displayed in .

[0044] In the embodiment of the present invention, since the user server attached to each VTEP device may have a smooth migration requirement, each VTEP device may serve as a source VTEP device. exist figure 1 In the application scenario shown, taking VTEP device 1 as the source VTEP device as an example, the processing of other VTEP devices as source VTEP dev...

Abstract

The present invention provides a data migration method and device. The method includes: a source VTEP device determines the sending time stamp of a delay detection message, adds the sending time stamp to the delay detection message, and sends it to other VTEP devices The delay detection message; after receiving the delay detection message, the source VTEP device determines the receiving timestamp of the delay detection message, and uses the sending timestamp and the receiving timestamp to calculate Delay time: the source VTEP device sends the delay time to the SDN controller, and the SDN controller uses the delay time to determine the destination VTEP device corresponding to the source VTEP device. Through the technical solution of the present invention, a VTEP device with a very short delay time can be selected as the target VTEP device, and the time for data to be successfully migrated to the target VTEP device is relatively short, which improves the speed and efficiency of data migration, and reduces the risk of data migration failure .

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data migration method and device. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new type of network innovation architecture. Its core idea is to separate the control plane of network equipment from the forwarding plane to achieve flexible control of network traffic and provide core network and application innovation. good platform. In SDN, VXLAN (Virtual eXtensibleLocal Area Network, Virtual Extensible Local Area Network) network can usually be used to connect various network devices (such as Openflow switches). The network devices in the VXLAN network can be called VTEP (VXLAN Tunnel End Point, VXLAN tunnel endpoint) device. VXLAN network is based on IP network, and adopts "MAC (Media Access Control, Media Access Control) inUDP (User Datagram Protocol, User Datagram Protocol)" encapsulation form of Layer 2 VPN (Vir...
