Embodiment Construction

[0031]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] Currently, if figure 1 As shown, the OpenStack network includes a control node 100 , a network node 200 , a network node 201 and a computing node 301 . In practical applications, an OpenStack network may include multiple computing nodes, and here only one computing node is used as an example for illustration.

[0033] If the currently running network node is the network node 200, the process of pointing the message sent by the computing node 301 to the ...

Abstract

The embodiment of the invention provides a network node switching method and device. A SDN (Software Defined Network) controller is connected with a control node; the control node is connected with at least two network nodes; between a switch connected with each network node and a switch connected with each computing node, a tunnel established by using a VTEP-IP (Virtual eXtensible LAN Tunnel End Point-Internet Protocol) address corresponding to the network node exists; a first network node sends a first VTEP-IP address corresponding to the first network node to the control node; the control node sends the first VTEP-IP address to the SDN controller; the SDN controller respectively generates a forwarding flow table for the switch connected with each computing node according to the first VTEP-IP address and issues the forwarding flow tables to the corresponding switches; and the forwarding flow tables are used for indicating to send messages to the switch connected with the first network node by a target IP address for the tunnel with the first VTEP-IP address. By applying the network node switching method and device provided by the embodiment of the invention, current-off time in the network node switching process is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for switching network nodes. Background technique [0002] The OpenStack network includes control nodes, network nodes, and computing nodes. The control nodes control and manage the network nodes and computing nodes. The computing nodes send packets sent by virtual machines to the external network to the network nodes. deal with. [0003] At present, in order to improve the reliability of the network, the OpenStack network often includes two network nodes, which are respectively marked as A and B, and the network node A is running, that is, the computing node sends the message sent to the external network to the network node A for processing. ; When network node A fails, the control node in the OpenStack network switches the running network node to network node B, that is, the computing node sends the message sent to the external network to network node ...
