Abstract
A method, in a network controller of a control plane in a software defined network (SDN) coupled to a network element (NE) of a data plane in the SDN, of resynchronizing forwarding table entries of the NE according to forwarding table entries of the network controller is disclosed. The method includes causing the NE to update a first subset of forwarding table entries from a set of one or more of forwarding table entries to include a post-synchronization indicator. The method continues with causing the NE to delete, following the update of the first subset of forwarding table entries, a second subset of zero or more forwarding table entries from the set of forwarding table entries, where each forwarding table entry from the second subset includes a pre-synchronization indicator.
