NTUA in INTUIT : Areas of Interest, Role and Potential Contribution

1
NTUA in INTUIT Areas of Interest, Role and
Potential Contribution

• J.Soldatos
• National Technical University of Athens
• Contact e-mail jsoldat_at_telecom.ntua.gr

2
Outline

• NTUA Research Interst in INTUIT
• Multihoming Solution
• DNS discovery
• Migration Secnarios
• NTUA Expertise
• Embedded systems software programming (including
  RGs)
• Internet architecture specification / Network
  Modeling
• Wireless LAN (IEEE802.11), Bluetooth, HiperLan2

3
Multihoming (1) Architecture Specification

• Leverage / Extend IETF work (Host Site
  Multihoming)
• Site exit issues - Source Address dependent
  routing
• Mobile IPv6 based solutions ? aggregate per
  flow interface selection
• Multihoming with Route Aggregation (Multiple
  ISPs) / RFC2260
• Combination of route renumbering with mobility
  mechanisms (e.g., for preserving connections on
  failures)
• Scalabiliy concerns (minimum DFZ
  entries/advertisements)
• Specify necessary agreements, SLAs between SPs
  for site MH

4
Multihoming (2) - Demonstration

• Scenarios
• Fault Resilience Redundant Connections
• Load Balancing Traffic Enginering
• Service Value Tarifing
• Terminal configuration source address selection
  ? Terminal Agent / Proxy (e.g., in PCs but also
  in wireless terminals using the NOKIA J2ME
  toolkit)

5
DNS Discovery Configuration

• Solutions (simple to more sophisticated)
• Well known unicast address (may be useful for a
  1st phase demonstrator)
• DNS server in RGs ? quite costly option
• More sophisticated Discovery DHCP6
• Private vs. Public Domain name
• Global DNS service provision ? Implications at
  the ISP side
• Directory issues use of FQDN ? host communication
  mobility

6
Home Networking Migration Scenarios

• Study IPv4/IPv6 migration home networking
• NAT, IPv4 tunnel to IPv6 Server ? IPv6
  connectivity over IPv4
• Study of DNS support (Gateway side, provider side)

Hub
Laptop (Dual Stack)
WorkStation (Dual Stack)
Residential Gateway (Programmable / Linux box)
IPv6 Server
Relay Router
IPv4 SP
IPv6 Network
7
Relevant NTUA expertise

• Embedded systems software
• Fault tolerant, QoS
• Interworking Gateway (NETGATE)
• Programming the RG (InAccessNetworks.com)
• IP architecture / specification
• TEQUILA, AQUILLA
• IPv6 ? ANDROID
• Wireless Standards
• HIPERLAN2, UMTS, DVB-T (MONASIDRE)
• UMTS, HIPERLAN2 (FITNESS)

8
NTUAs Role Summary

• Areas of Interest (Multihoming, DNS discovery,
  Interworking Migration Ipv4/IPv6)
• Application Developer - Software
• Depending on the specific areas that industrial
  partners require assistance
• Architecture Specification work
• NTUA volunteers to contribute to the technical
  non-technical writing of the proposal
