Embodiment Construction

[0033] The present invention solves the problem of inefficiency caused by one-by-one upgrade by automatically upgrading each controller in the controller cluster step by step, and also avoids excessive pressure on the version server and excessive bandwidth occupation of the upstream path during simultaneous upgrade , Issues affecting user business.

[0034] To further illustrate the present invention, the following examples are provided:

[0035] Please refer to Figure 1A , Figure 1A The networking structure of the controller cluster in the SDN network according to an exemplary embodiment of the present invention is shown, and the controller cluster in the networking structure includes a LeaderController (that is, a management controller) and other Controllers (that is, an area controller) controller, which is different from LeaderController). At the same time, multiple Regions are established in the SDN network, and each Region contains one or more Controllers. for exampl...

Abstract

The invention provides a controller cluster upgrading method and device. The method and the device are applied to a management controller and a region controller in a controller cluster under an SDN framework, and the method is used for gradually upgrading the management controller and the region controller in the controller cluster to solve the problem of low progressive upgrading efficiency and avoid an overlarge pressure of an edition server.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for upgrading a controller cluster. Background technique [0002] With the increasing development of Overlay (overlay) network technology, the scale of the Overlay network based on the SDN (Software Defined Network, software-defined network) framework is gradually increasing, making large-scale data centers use a large number of SDN controllers to ensure network stability. [0003] However, the increase in the number of SDN controllers also makes the upgrade of SDN controllers very cumbersome and complicated: if the SDN controllers are upgraded one by one, the upgrade efficiency is very low; if all the SDN controllers are upgraded at the same time, then Not only is the pressure on the version server storing the upgrade file too high, but a large amount of data may also cause an impact on upstream devices, occupying bandwidth and affecting user services....
