  2. IPv6 for Space? • Introduction • IPv4 vs. IPv6 • Use of IPv6 • Advantages/Disadvantages • Conclusion Space Internet Workshop IV

  3. IPv6 for Space? • Differences between IPv4 and IPv6 • Address Space • Quality of Service • Security • Mobility • Multicast and Anycast • Reconfiguration Support • Network Management Space Internet Workshop IV

  4. IPv6 for Space? IPv4 Header IPv6 Header Space Internet Workshop IV

  5. IPv6 for Space? • Address Space • 128 bit address • Addressing Schemes • Hierarchy • Simple header Space Internet Workshop IV

  6. IPv6 for Space? • Quality of Service • “Flow” field • Hosts can identify packets of a particular traffic stream • Security • IPSec is standard • Provides AH and ESP Space Internet Workshop IV

  7. IPv6 for Space? • Why should we use IPv6 for space? • In a IP-based space communication network, more IP addresses are needed • NAT is no longer needed • Peer-to-peer communication will be possible Space Internet Workshop IV

  10. IPv6 for Space? • Future Work • IPSec has already been installed on 2 nodes in SCEF • Security will be incorporated into emulation facility to accommodate scenarios using IPv6 • Test performance in space environment through emulation Space Internet Workshop IV

  11. IPv6 for Space? • Conclusion • Advantages • At this high level view, the address space appears to be the biggest advantage • Disadvantages • Availability of IPv6 Space Internet Workshop IV
