Abstract: This disclosure relates enhancements to a SDN system including the controller, southbound interface, and OpenFlow devices, to enable hash-routing, and describes SDN applications making use of this feature. More specifically, the application relates to Software Defined Networking (e.g., OpenFlow) enhancements to facilitate the deployment and usage of Distributed Hash Tables, for example as part of Information Centric Networking (ICN).

Abstract: A method and apparatus are described for supporting advanced distributed and dynamic mobility management (DMM) features with multiple flows anchored at different gateways. A software defined networking (SDN) controller may support the attachment of a wireless transmit/receive unit (WTRU) to a network. The SDN controller may receive initial attachment signaling from a point of attachment (PoA) indicating that the WTRU initially attached to the network. The anchor node may be a distributed gateway (D-GW). The SDN controller may select an anchor node to serve the WTRU Internet protocol (IP) flow traffic. Initial attachment signaling, intra-anchor node handover, inter-anchor node handover, new anchor node allocation and inter-domain mobility across virtualized operators are also described.

Abstract: Systems, methods, and instrumentalities are disclosed to implement hierarchical policies for local networks. In one representative method, a first local node may establish a dedicated local IP access (LIPA) packet data network (PDN) connection for a local service provided via a local network. The method may include responsive to a request for access to the local service, the first local node receiving a quality of service (QoS) requirement for the requested local service; sending, to a second local node, a dedicated bearer request with a specified QoS level based on a global policy and network-information specific to the local network; and receiving a dedicated bearer response with the specified QoS level.
