Sychronization of configuration file of virtual application distribution chassis

摘要

Synchronization of configuration files of a virtual application distribution chassis, includes: processing a configuration command received by a master blade; updating a first configuration file with the configuration command and an updated tag by the master blade; sending a configuration message by the master blade to the slave blades informing of the updated configuration file, the configuration message comprising the updated tag; in response to receiving the configuration message by a given slave blade of the one or more slave blades, comparing the updated tag in the configuration message with a tag in a second configuration file stored at the given slave blade; and in response to determining that the updated tag in the configuration message is more recent than the tag in the second configuration file stored at the given slave blade, sending a request for the updated configuration file to the master blade by the given slave blade.

主权项

1. A method for synchronizing configuration files of a virtual application distribution chassis comprising a plurality of blades, comprising:
processing a configuration command received from an administrative host by a master blade of the plurality of blades of the virtual application distribution chassis; updating a first configuration file with the received configuration command and an updated tag by the master blade, the updated first configuration file comprising the received configuration command; sending a configuration message in response to receiving the configuration command by the master blade to one or more slave blades of the plurality of blades informing of the updated configuration file, the configuration message comprising the updated tag; in response to receiving the configuration message by a given slave blade of the one or more slave blades, comparing the updated tag in the configuration message with a tag in a second configuration file stored at the given slave blade; and in response to determining that the updated tag in the configuration message is more recent than the tag in the second configuration file stored at the given slave blade, sending a request for an updated configuration file to the master blade by the given slave blade.
