Abstract
A method in a network controller of a control plane in a software defined network (SDN) coupled to a plurality of network elements (NEs) of a data plane in the SDN is described. The method includes causing the plurality of NEs to install one or more packet handling rules for a selected type of packet so that the NEs forward only a subset of data for each packet of the selected type to the network controller. The method further includes receiving the subset of data for each packet of the selected type and composing a whole packet of the selected type that includes the subset of data.
