IP address◦ Both Identifier and Locator
Assumptions on “Fixed” Link and Host◦ Host-based TCP/IP Protocols
A “Single(same)” IP protocols for data de-livery◦ Without considerations of “Heterogeneous”
Networks Integration of Data and Control Functional-
ity◦ “Patch-on” Mobility Protocols◦ IP is extended to MIP, PMIP, ..
Problems in Current Inter-net

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 Back-bone Networks
Functional Separation for Mobility Control and Data Delivery◦ Signaling-based Mobility Control ◦ (c.f.) MIP: data-based mobility control
Design Principles: Separa-tion !

Name, Host ID, Locator
Name◦ Human readable, Services specific◦ Hostname, Telephone number (E.164), NAI
(user@realm),.. 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 applica-
tions) Locator (LOC)
◦ IP address of AR (Access Router attached to hosts)
◦ Network Locator9
Name, Host ID, Locator
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
Link ID (LID) & HBP
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

Protocol Stack (for Data Plane) Network Layer is divided into
◦ HID-based (end-to-end) Communication Sub-layer: HCP
◦ Network Delivery Sub-layer: ADP, BDP (IP)

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 ad-
dress◦ Any Others,…
Access Delivery Protocol

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
Protocols for Mobility Control
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
