Abstract: Aspects of data re-direction are described, which can include software-defined networking (SDN) data re-direction operations. Some aspects include data re-direction operations performed by one or more virtualized network functions. In some aspects, a network router decodes an indication of a handover of a user equipment (UE) from a first end point (EP) to a second EP, based on the indication, the router can update a relocation table including the UE identifier, an identifier of the first EP, and an identifier of the second EP. The router can receive a data packet for the UE, configured for transmission to the first EP, and modify the data packet, based on the relocation table, for rerouting to the second EP. In some aspects, the router can decode handover prediction information, including an indication of a predicted future geographic location of the UE, and update the relocation table based on the handover prediction information.

Abstract: One embodiment provides a network device. The network device includes a a processor including at least one processor core; a network interface configured to transmit and receive packets at a line rate; a memory configured to store a scheduler hierarchical data structure; and a scheduler module. The scheduler module is configured to prefetch a next active pipe structure, the next active pipe structure included in the hierarchical data structure, update credits for a current pipe and an associated subport, identify a next active traffic class within the current pipe based, at least in part, on a current pipe data structure, select a next queue associated with the identified next active traffic class, and schedule a next packet from the selected next queue for transmission by the network interface if available traffic shaping token bucket credits and available traffic class credits are greater than or equal to a next packet credits.
