Embodiment Construction

[0033] Such as figure 1 , is a network architecture diagram of a controller controlling firmware update according to an embodiment of the present invention. The network architecture includes a controller 1 and multiple network clusters (including at least a first network cluster A and a second network cluster B). The first network cluster A and the second network cluster B are respectively connected to the controller I in a wired or wireless manner, and perform corresponding operations according to the control instructions of the controller I, such as network devices in these network clusters Implement the upgrade operation.

[0034] In an embodiment, each network cluster is provided with a sub-controller, wherein the first network cluster A is provided with a sub-controller II, and the second network cluster B is provided with a sub-controller III. The sub-controllers II and III are connected to the controller I, receive control instructions from the controller I and perfor...

Abstract

An update method that should be used in the controller. The controllers are connected to a network cluster, the network cluster includes a first network cluster and a second network cluster, the first network cluster includes a plurality of first network devices, and the second network cluster includes a plurality of second network devices. A plurality of first traffic usage information corresponding to a plurality of first network devices and a plurality of second traffic usage information corresponding to a plurality of second network devices are collected. According to the multiple first traffic usage information and the multiple second traffic usage information, respectively calculate the total traffic of the corresponding network cluster and the traffic usage difference value among the network devices in the network cluster, and then calculate the priority update value of the corresponding network cluster. According to the magnitude of the priority update value, the network devices in the network cluster with a large priority update value are preferentially updated. The invention also provides a controller. The present invention reduces the influence caused by downtime due to update failures through batch updates.

Description

technical field [0001] The invention relates to the technical field of communication. Background technique [0002] In a network architecture, sometimes a firmware upgrade may cause some network devices in the network architecture to go down, thereby causing the entire network architecture to fail to operate normally. It often takes a lot of time and cost to repair these network devices. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a method for updating firmware, which reduces the impact of downtime due to update failures by updating in batches. [0004] In view of this, the embodiment of the present invention also provides a controller, which can reduce the impact caused by downtime due to update failure by updating in batches. [0005] A firmware update method provided by an embodiment of the present invention is applied to a controller. The controller is connected to the network cluster. The network clusters inc...
