Synchronization of configuration file of virtual application distribution chassis
First Claim
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;
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 comprising a plurality of configuration commands 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 receiving the configuration command by the administrative host;
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 first configuration file from at least one slave blade; and
sending a second configuration message comprising the updated first configuration file and updated tag, the updated first configuration file comprising the plurality of configuration commands of the first configuration file and the received configuration command.

Abstract
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.

11. A non-transitory computer readable storage medium having embodied thereon a computer readable program, wherein the computer readable program when executed by one or more processors performs a method comprising:
-
processing a configuration command received from an administrative host by a master blade; 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 comprising a plurality of configuration commands 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 receiving the configuration command by the administrative host; 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 first configuration file from at least one slave blade; and sending a second configuration message comprising the updated first configuration file and updated tag, the updated first configuration file comprising the plurality of configuration commands of the first configuration file and the received configuration command.

12. A system, comprising:
a plurality of blades operatively coupled as a virtual application distribution chassis within a data network, wherein each blade comprises a processor and a non-transitory computer readable storage medium having a computer readable program, the computer readable program when executed by the processor causes a master blade of the plurality of blades to; process a configuration command received from an administrative host by the master blade of the plurality of blades of the virtual application distribution chassis; determine 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; update a first configuration file comprising a plurality of configuration commands and generate an updated tag associated with the updated first configuration file, the updated first configuration file comprising the received configuration command; send a first configuration message to one or more slave blades of the plurality of blades informing of the updated configuration file in response to receiving the configuration command by the administrative host; in response to the first configuration message informing the one or more slave blades of the updated configuration file, receive a request for the updated first configuration file from at least one slave blade; and send a second configuration message comprising the updated first configuration file and updated tag, the updated first configuration file comprising the plurality of configuration commands of the first configuration file and the received configuration command. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
