Abstract
A method for electing a master blade in a virtual application distribution chassis (VADC), includes: sending by each blade a VADC message to each of the other blades; determining by each blade that the VADC message was not received from the master blade within a predetermined period of time; in response, sending a master claim message including a blade priority by each blade to the other blades; determining by each blade whether any of the blade priorities obtained from the received master claim messages is higher than the blade priority of the receiving blade; in response to determining that none of the blade priorities obtained is higher, setting a status of a given receiving blade to a new master blade; and sending by the given receiving blade a second VADC message to the other blades indicating the status of the new master blade of the given receiving blade.
