The embodiment of the invention provides a data communication method, system and device of a network node and a computer readable storage medium. The method comprises the following steps: a network node management and control platform sends a mirror network upgrading file to a to-be-upgraded network node; the to-be-upgraded network node performs network upgrading by using the received mirror image network upgrading file; the network node to be upgraded actively establishes a first communication link with the network node management and control platform when network upgrading is completed; and the to-be-upgraded network node and the network node management and control platform perform data communication through the first communication link. In this way, it can be avoided that due to the fact that a network node management and control platform needs to poll network nodes, management personnel need to repeatedly test the restart speed and synchronization time of different types of network nodes when different mirror image versions are loaded, and then the appropriate polling opportunity can be determined; and the communication efficiency between the network node management and control platform and the to-be-upgraded network node can also be improved by connecting back to the network node management and control platform, and resource consumption caused by polling is avoided.
Description
technical field [0001] Embodiments of the present disclosure generally relate to the Internet field, and more specifically, relate to a data communication method, system, device, and computer-readable storage medium of network nodes. Background technique [0002] At present, in the SDN (Software Defined Network, software-defined network) type WAN communication network, if it is necessary to upgrade the network function of the transmission nodes that make up the network, it is usually necessary to import a specific image file (group ) and start the image file management service, and distribute archive files such as *.tar.gz or qcow2 to each network node through the service process. [0003] The network node management and control platform will execute a set of configuration commands on the network node to activate the distributed archive and install the image file. Network nodes usually reboot automatically after installing an image to initialize the system and load the inst...
