Embodiment Construction

[0094] 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.

[0095] The embodiment of the present invention is applied to SDN, and the SDN is connected to the external network through the border gateway, such as figure 1 As shown, the SDN includes an SDN controller, at least two virtual machines, a virtual switch of the virtual machines (that is, a virtual switch to which the virtual machines access) and a dynamic routing agent. Wherein, multiple virtual machines can access the same virtual switch, but each virtual mach...

Abstract

Embodiments of the invention disclose a dynamic route configuration method, a device and a system thereof and relates to the computer field. A problem of a large workload and inconvenient adjustment resulting from manually configuring a route using a distributed gateway is solved. The specific scheme comprises the following steps that an SDN controller receives a route learning message transmitted by a dynamic route agent; a SDN controller updates at least one first route table entry according to external route information; the SDN controller converts a second route table entry to a first flow table entry when receiving a data packet which is from a virtual machine and is transmitted by a virtual switch of the virtual machine; and the SDN controller transmits the first flow table entry to the virtual switch of the virtual machine so as to indicate the virtual switch of the virtual machine to forward a data packet from the virtual machine according to the first flow table entry and via a distributed gateway deployed on the virtual switch of the virtual machine.

Description

technical field [0001] The invention relates to the field of computers, in particular to a dynamic routing configuration method, device and system. Background technique [0002] Software Defined Network (English: Software Defined Network, abbreviation: SDN) is a network that separates the control plane and data plane of network devices. At present, a technology commonly used in SDN is OpenFlow technology. Using this technology, the SDN controller can control the forwarding of data packets by the virtual switch by controlling the flow table on the virtual switch. With the continuous maturity of SDN technology, more and more operators / cloud service providers use SDN as the preferred solution for managing data centers. [0003] Inside the data center, one or more virtual machines can be deployed on a physical server, and each virtual machine needs to pass through a centralized gateway and a border gateway when sending data packets to devices outside the data center. However, ...
