  • Method and apparatus for seamless mobility techniques in content-centric network
    Patent number: 9191459
    Abstract: A networking system for a content-centric-network (CCN)/named-data networking (NDN) comprising a first point of attachment (PoA) configured to communicate with a mobile node (MN) and maintain a forwarding state for the MN to support seamless mobility for the MN, and a second PoA configured to communicate with the MN and obtain the forwarding state for the MN from the first PoA after a handoff of the MN from the first PoA to the second PoA, wherein the forwarding state is used to exchange a plurality of interests and a plurality of data responses between the MN and the CCN/NDN.
    Type: Grant

  • Seamless mobility schemes in names-data networking using multi-path routing and content caching
    Patent number: 8837511
    Abstract: A content-centric-network (CCN)/named-data networking (NDN) system to support seamless mobility for a mobile node (MN) comprising a first point of attachment (PoA) configured to indicate to the MN that attaches to the first PoA one or more neighbor PoAs and to multicast an interest for content from the MN to the neighbor PoAs in a CCN or NDN when the MN starts a handoff procedure, and a second PoA from the one or more neighbor PoAs of the first PoA configured to receive the multicast interest from the first PoA, forward the interest to the CCN or NDN, receive content data from the CCN or NDN, and forward the content data to the MN.
