SYSTEM FOR MANAGING CONFIGURATION UPDATES IN CLUSTER OF COMPUTATIONAL DEVICES

摘要

A system for managing configuration updates in a cluster of computational devices that includes a master device and a set of participant devices. The master device receives a first configuration command from a user, executes it and updates a configuration version number to a current configuration version number. Thereafter, the master device transmits a multicast message including the current configuration version number to the participant devices. A first participant device sends a configuration request to the master device for transmitting the first configuration command. Thereafter, the first participant device receives the first configuration command from the master device and updates its configuration version number to the current configuration version number.

1. A method for managing configuration updates in a cluster of computational devices, wherein the cluster includes a master device and a plurality of participant devices, the method comprising:
receiving a plurality of configuration commands including a first configuration command at a management engine of the master device; shifting the first configuration command from the management engine to a command cache of the master device based on a command type of the first configuration command; executing the first configuration command at the master device by a processor of the master device; updating a configuration version number of the master device as a current configuration version number that corresponds to the first configuration command; moving the first configuration command from the command cache to a version history database of the master device, wherein the version history database stores a mapping between the plurality of configuration commands and corresponding configuration version numbers; multicasting a configuration availability message corresponding to the first configuration command to the plurality of participant devices; receiving a configuration request from a first participant device of the plurality of participant devices when a processor of the first participant device determines that a current configuration version number of the first participant device is less than the current configuration version number of the master device; and transmitting the first configuration command to the first participant device for execution thereby.
