SYSTEMS AND METHODS FOR MAINTAINING PERSISTENCE BY A BACKUP VIRTUAL SERVER

摘要

The present disclosure presents systems and methods for maintaining persistence of a backup virtual server on connections currently serviced by the backup virtual server. A virtual server operating on an intermediary network device and identified as a primary virtual server for a first connection may receive a request via the first connection. The intermediary device may forward the first request to a backup virtual server of the virtual server in response to identifying that the virtual server is unavailable. The intermediary device may later identify that the virtual server is available. The virtual server may establish a new connection responsive to receiving a connection request while the intermediary device may forward a second request received via the first connection to the backup virtual server instead of the virtual server responsive to identifying that the virtual server is configured not to preempt the backup virtual server from maintaining connections currently maintained by the backup virtual server.
