Abstract
To accommodate graceful offloading of connections from a port of a network element, thereby allowing the port to be decommissioned, both existing and new connections allocated to that port according to a load balancing protocol are replicated on a backup port. Thereafter, or concurrently therewith, the port is configured to drop acknowledgements of the new connections, and the port is monitored so as to eventually identify an absence of connections thereon. At that time, the port may be decommissioned inasmuch as all new connections will have been established on the backup port and no previously existing connections on the original port will remain.
