Abstract
A method of accelerating link loss detection includes providing a plurality of IP devices in communication with a central server. The method includes: a first one of the plurality of IP devices broadcasting a link loss message to others of the plurality of IP devices when communication between the first one of the plurality of IP devices and the central server is interrupted, one of the others of the plurality of IP devices performing a verification process to confirm interruption of communication between the central server and the plurality of IP devices and upon successful completion of the verification process, the one of the others of the plurality of IP devices broadcasting a link loss confirmation message and each of the IP devices terminating communication with the central server and reconnecting to a new central server following receipt of the link loss confirmation message.
