Abstract
Example methods are provided for filter-based control information query in a software-defined networking (SDN) environment that includes a host and a network management entity. One example method may comprise identifying a first query key for the host to query for control information associated with the first query key from the network management entity; and applying a set membership filter to determine whether the first query key is possibly a member of a set of second query keys that are known to the network management entity. The method may also comprise, in response to determination that the first query key is possibly a member of the set of second query keys, generating and sending a query message to the network management entity over a control-plane channel to query for the control information associated with the first query key.
