Presentation Outline

• Background on Internet Protocol (IP)
• Internet Protocol version 6 (IPv6)
• IPv6 Project

3
Internet Protocol

• IP is a international standard
• defines how data is sent from one device to
  another over the Internet
• IPv4 has been used for 20 years
• It is now indispensable

4
Current Limitations

• Many existing issues with IPv4
• A lack of adequate address space to meet growing
  demand
• Address-conservation techniques causing a lack of
  end-to-end connectivity between computers and
  other devices
• The need to support new network services that did
  not exist when IPv4 was developed

6
Creating More Addresses

• NAT allows many private addresses with one global
  address
• Each packet is translated
• Created end-to-end connection issues
• If NAT fails, then all devices lose connectively

7
New Services Demanded

• IPsec
• IPv4 packets are sent in the clear
• Provides authentication
• Quality of Service
• Allows confirmation of receipt
• Gives priority to certain packets
• Widespread use of NAT hurts use

8
The Solution

• IPv6 is an evolutionary but important improvement
  over IPv4
• Positions the Internet for future growth
• Supports end-to-end connectivity
• Promotes trustworthy networking
• IPv6 permits easier networking

9
Triggers for IPv6

• IPv4 address space exhaustion in general
• NAT use hampers growth of applications
• Need for uniformity over add-on protocols (QoS,
  IPsec, etc)
• DoD Mandate by 2008

10
Project Objectives

• Learn how IP networks and IPv6 operate
• Do interoperability testing
• Research the transition from IPv4 to IPv6

11
Technical Approach

• Implement and test the Test Bed Network
• Research Deployment
• Tunneling
• Dual Stack works best

Results

• IPv6 works
• A long transition period
• No immediate need to implement IPv6
• CG has a working IPv4 infrastructure
• In the future, IPv6-applications and DoDs usage
  will drive migration
• SIPRNET communications on Deepwater

14
Conclusions

• Summary
• IPv6 has useful features
• No need to implement now
• Buy IPv6-compatible hardware and software

15
Restoring End-to-End

• Restores the Promise of Online Collaboration
• IP Telephony
• IP Video Conferencing

16
Built-in Protocols

• IPsec - packet encryption and source
  authentications
• QoS Allows priority of certain information
  streams and receipts
• Auto-configuration plug and play
