Abstract
Methods, computer-readable media, and apparatuses for network flow state preservation include migration of at least one application hosted on a first server device to a second server device coupled to a second traffic management device is detected at a first traffic management device. At least a portion of connection state information associated with a network connection between at least one client device and the application is communicated by the first traffic management device to the second traffic management device via a communication channel between the first and second traffic management devices. The application is provided by the first traffic management device to the at least one client device during the migration based upon the connection state information.
