  1. 1. NTUA in INTUIT : Areas of Interest, Role and Potential Contribution J.Soldatos National Technical University of Athens Contact e-mail: [email_address]
  2. 2. Outline <ul><li>NTUA Research Interst in INTUIT : </li></ul><ul><ul><li>Multihoming Solution </li></ul></ul><ul><ul><li>DNS discovery </li></ul></ul><ul><ul><li>Migration Secnarios </li></ul></ul><ul><li>NTUA Expertise: </li></ul><ul><ul><li>Embedded systems software programming (including RGs) </li></ul></ul><ul><ul><li>Internet architecture specification / Network Modeling </li></ul></ul><ul><ul><li>Wireless LAN (IEEE802.11), Bluetooth, HiperLan2 </li></ul></ul>
  3. 3. Multihoming (1) – Architecture & Specification <ul><li>Leverage / Extend IETF work (Host & Site Multihoming): </li></ul><ul><ul><li>Site exit issues - Source Address dependent routing </li></ul></ul><ul><ul><li>Mobile IPv6 based solutions  aggregate & per flow interface selection </li></ul></ul><ul><ul><li>Multihoming with Route Aggregation (Multiple ISPs) / RFC2260 </li></ul></ul><ul><ul><li>Combination of route renumbering with mobility mechanisms (e.g., for preserving connections on failures) </li></ul></ul><ul><ul><li>Scalabiliy concerns (minimum DFZ entries/advertisements) </li></ul></ul><ul><ul><li>Specify necessary agreements, SLAs between SPs for site MH </li></ul></ul>
  4. 4. Multihoming (2) - Demonstration <ul><li>Scenarios: </li></ul><ul><ul><li>Fault Resilience – Redundant Connections </li></ul></ul><ul><ul><li>Load Balancing – Traffic Enginering </li></ul></ul><ul><ul><li>Service Value – Tarifing </li></ul></ul><ul><ul><li>Terminal configuration – source address selection  Terminal Agent / Proxy (e.g., in PCs but also in wireless terminals using the NOKIA J2ME toolkit) </li></ul></ul>
  5. 5. DNS Discovery & Configuration <ul><li>Solutions (simple to more sophisticated): </li></ul><ul><ul><li>Well known unicast address (may be useful for a 1 st phase demonstrator) </li></ul></ul><ul><ul><li>DNS server in RGs  quite costly option </li></ul></ul><ul><ul><li>More sophisticated Discovery : DHCP6 </li></ul></ul><ul><ul><li>Private vs. Public Domain name </li></ul></ul><ul><ul><li>Global DNS service provision  Implications at the ISP side </li></ul></ul><ul><ul><li>Directory issues use of FQDN  host communication & mobility </li></ul></ul>
  6. 6. Home Networking Migration Scenarios <ul><li>Study IPv4/IPv6 migration home networking: </li></ul><ul><ul><li>NAT, IPv4 tunnel to IPv6 Server  IPv6 connectivity over IPv4 </li></ul></ul><ul><ul><li>Study of DNS support (Gateway side, provider side) </li></ul></ul>IPv6 Network IPv4 SP Relay Router Hub Laptop (Dual Stack) WorkStation (Dual Stack) Residential Gateway (Programmable / Linux box) IPv6 Server
  7. 7. Relevant NTUA expertise <ul><li>Embedded systems software: </li></ul><ul><ul><li>Fault tolerant, QoS </li></ul></ul><ul><ul><li>Interworking Gateway (NETGATE) </li></ul></ul><ul><ul><li>Programming the RG (InAccessNetworks.com) </li></ul></ul><ul><li>IP architecture / specification: </li></ul><ul><ul><li>TEQUILA, AQUILLA </li></ul></ul><ul><ul><li>IPv6  ANDROID </li></ul></ul><ul><li>Wireless Standards: </li></ul><ul><ul><li>HIPERLAN2, UMTS, DVB-T (MONASIDRE) </li></ul></ul><ul><ul><li>UMTS, HIPERLAN2 (FITNESS) </li></ul></ul>
  8. 8. NTUA’s Role Summary <ul><li>Areas of Interest (Multihoming, DNS discovery, Interworking & Migration Ipv4/IPv6) </li></ul><ul><li>Application Developer - Software </li></ul><ul><ul><li>Depending on the specific areas that industrial partners require assistance </li></ul></ul><ul><li>Architecture & Specification work </li></ul><ul><li>NTUA volunteers to contribute to the technical & non-technical writing of the proposal </li></ul>
