 IP address ◦ Both Identifier and Locator  Assumptions on “Fixed” Link and Host ◦ Host-based TCP/IP Protocols  A “Single(same)” IP protocols for data delivery ◦ Without considerations of “Heterogeneous” Networks  Integration of Data and Control Functionality ◦ “Patch-on” Mobility Protocols ◦ IP is extended to MIP, PMIP,.. 6

 Mobile Oriented (and Static Allowed)  Separation of Identifier and Locator ◦ Host Identifier and Network Locator (HINLO) ◦ Address‐free Host ◦ ID‐based Global Communications ◦ LOC‐based Local Routing  Protocol Separation for Access and Backbone Networks  Functional Separation for Mobility Control and Data Delivery ◦ Signaling-based Mobility Control ◦ (c.f.) MIP: data-based mobility control 7

 Name ◦ Human readable, Services specific ◦ Hostname, Telephone number (E.164), NAI  Host Identifier (HID) ◦ Globally Unique ◦ We will focus on 128-bit HID (cf. HIT, AKARI) This is ID (not IP address )  Beneficial for application compatibility (IPv6 applications)  Locator (LOC) ◦ IP address of AR (Access Router attached to hosts) ◦ Network Locator 9

 Link ID (LID) ◦ Used by ADP for data delivery between Host and AR  Specific to the underlying access network ◦ Examples:  MAC address (IEEE 802 LAN, WLAN): if ADP is not used  Connection ID (WiBro), GTP Tunnel ID (Cellular)  (Note) IPv6 Link-Local address, IPv4 Private address (NAT)  HID Binding Protocol: HID  LID ◦ A control protocol between Host and AR ◦ Each host shall bind its HID and LID to AR 10

 Name-HID mapping architecture ◦ Possible examples (for various naming schemes) ◦ Mapping Scenarios and Abstract Procedures  DNS maybe a simple example of NMS  CCN (Contents Centric Networking) support (??) 11

 Notations ◦ NMS: Name-HID Mapping System ◦ LBS: LOC Binding System ◦ ACA: Access Control Agent ◦ HID: Host ID ◦ LID: Link ID ◦ LOC: Locator ◦ HBP: HID Binding Protocol ◦ ADP: Access Delivery Protocol ◦ BDP: Backbone Delivery Protocol (= IPv4/IPv6) ◦ LMP: LOC Management Protocol 13

14  Network Layer is divided into ◦ HID-based (end-to-end) Communication Sub-layer: HCP ◦ Network Delivery Sub-layer: ADP, BDP (IP)

 HID-based Communication Protocol (HCP) ◦ IPv6-compatible format (40 bytes) 17

18

 Data Packet Delivery between Host and AR  Examples ◦ Null: when MAC frame is used  LID = MAC address ◦ GTP (GPRS Tunneling Protocol) in Cellular Systems  LID = Tunnel ID ◦ WiBro Tunneling Protocol  LID = Connection ID (?) ◦ IPv6 or IPv4  LID = IPv6 Link-Local address, or Private IPv4 address ◦ Any Others,… 19

 HID Binding Protocol (HBP) ◦ Between Host and AR  LOC Management Protocol (LMP) ◦ LOC Binding (LB) and LOC Query (LQ) operations  Between ACA and LBS ◦ Handover Control operations  LOC Transfer (LT)  between neighboring ACAs  LOC Update (LU)  between local and remote ACAs 20

 Operations ◦ HID Binding: from Host to AR ◦ HID Query: from AR to Host  Considerations ◦ HID Cache (HC) ◦ Underlying Access Network  LAN, WLAN, WiBro, Cellular, Adhoc/Sensor Networks, DTN, … ◦ Relationship with ADP 21
