Synchronization of configuration file of virtual application distribution chassis

摘要

Methods and systems for synchronization of configuration files of a plurality of blades in a virtual application distribution chassis are disclosed. In an exemplary method, a master blade processes a configuration command, updates a first configuration file with the configuration command and generates an updated tag, and sends a configuration message to at least one slave blade of the virtual application distribution chassis informing of the updated configuration file. The configuration message is received by a given slave blade of the one or more slave blades and compared with 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, the slave blade sends a request for the updated configuration file to the master blade.

主权项

1. A method for synchronizing configuration files by a master blade of a virtual application distribution chassis comprising a plurality of blades, the method comprising:
processing a configuration command received from an administrative host by the master blade, the processing comprising identifying at least one slave blade from the plurality of blades in the virtual application distribution chassis for the configuration command; determining that the received configuration command applies changes to at least one network application implemented by one or more blades of the virtual application distribution chassis; updating a first configuration file with the received configuration command and generating an updated tag associated with the updated first configuration file, the updated first configuration file comprising the received configuration command; sending a first configuration message to one or more slave blades of the plurality of blades informing of the updated configuration file; in response to the first configuration message informing the one or more slave blades of the updated configuration file, receiving a request for the updated configuration file from at least one slave blade; and sending a second configuration message comprising the updated first configuration file and updated tag.
