Problems of Current Internet

Overloaded semantics of IP addressIdentifier and Locator as well

Single protocol for heterogeneous networksNo consideration of heterogeneous networks

Integration of data delivery and control function

No distinction between data plane and control plane

Centralized mobility controlHome Agent (central anchor) of Mobile IPTraffic overhead, failure by DoS attack, non-optimal routes

Geneva, Switzerland, 11 June 2012 9

Architectural Requirements for FN

Separation of identifier (ID) and locator (LOC)Permanent ID and Temporary LOC (Mobility, Multi-homing)

Separation of access/backbone networksSupport of Heterogeneous access networks

Separation of control plane from data planeControl (mobility) information: mission-criticalUser data packets: best-effort

Distributed mobility controlBuilt-in mobility control (cf. MIP: patch-on)Use of Optimized Route (Query-based signaling)Scalable management of ID-LOC mappings

Functional Requirements for FN

Location managementID-LOC mapping management for mobile hostsID-LOC Binding and Query Operations

Route optimizationDirect (Optimized) path between two communicating hosts

Handover controlSeamless handover for on-going sessionsRoute Update

Query-First Data Delivery(QFDD)

Three Functional Blocks

Geneva, Switzerland, 11 June 2012 16

HILL: Host ID & Local Locator(HID-based global comm. & LOC-based local routing)

Geneva, Switzerland, 11 June 2012 17

AdvantagesFree from address depletion problem

Not require globally unique address allocation (e.g. IPv4/6)Make private-to-private network communication possible very easily

More efficient to support mobility and multi-homingHelp to resolve the BGP routing table explosion problem

Secure HID provides security and privacy

DDMS: Dynamic Distributed Mapping System

AdvantagesMore efficient management than Agent-based Centralized LM of legacy Internet for mobile dominant environmentITO, single point of failure, unwanted traffic introduction, etc.

QFDD: Query First Data Delivery

Geneva, Switzerland, 11 June 2012 19

AdvantagesMore efficient delivery than the Send-First of legacy Internet for mobile dominant environment

ITO, optimized routing path, reduction of unwanted traffic introduction, transmission delay, etc.
