Contents Problem Statements Multi-network Our Standardization Plans

Problem Statements (1/2) Current communication Application layer Fixed parameters Difficulty of simultaneous use of multiple heterogeneous data in application Transport layer Single stream Use of single IP network connectivity IP layer Multiple IPv6 addresses over a single interface Multihoming without MAC/PHY considerations Difficulty of simultaneous use of multiple I/F MAC/PHY layer Use of single interface

Problem Statements (2/2) IPv6 Features Flexible packet format IPv6 extension headers and options Expanded addressing schemes Autoconfiguration Multihoming Quality of services Flow header Security and mobility support

Autoconf & multihoming Multi-network ? (1/4) Vertical (Cooperative) multihoming Application Layer Multihoming Transport Layer Multihoming Cognitive Process IP Layer Multihoming Autoconf & multihoming MAC Layer Multihoming Physical Layer Multihoming Multiple interface + Multiple MAC + Multiple IP address + Multiple Transport stream + Variable QoS (PHY layer) (Link layer) (Network layer) (Transport layer) (Application layer)

Multi-network ? (2/4) Conceptual Vertical multihoming
