2 Discussion Topics ERM Masters 2002 Points of Transition Transition Solutions Deployment Roadmap for DoD Current Deployment Models Note all Military U.S. Army Graphics were provided by CECOM FT Monmouth, New Jersey. Thanks to Ed Kierman and the PING Lab Team. Page 2

5 ERM Masters 2002 Where can Network Topology Transition take place? At the client network within the user network. At the edge of the user network to the provider. At the provider network for the user network. Client Network User Edge Network Provider Network Satellite Satellite dish Page 5

6 ERM Masters 2002 The Transition complexity will be exponential with a larger Mesh network topology Multiple client, edge, and provider networks will increase transition planning and staged deployment. Mobile IP Computing further complicates the Transition and creates a new decision point of IPv4 with NAT or IPv6 without NAT. Client Net Provider A Client Net Client Net Client Net Client Net Provider B Client Net User Network A Mobile IP User User Network B Mobile user must be able to connect to both User Networks and both Provider Networks, and change Home Agents in an Ad-Hoc manner from any Network point of attachment.

7 Points of Transition (Geography) ERM Masters 2002 Packets over a local link Packets over a site Packets within an Intranet (multiple sites ) Packets over a private Internet (multiple Intranets ) Packets over the public Internet Packets over a Mobile IP Network (Wireless) Packets over a Mobile IP Network (Wireless) and to a Broadband Network (Wireline) or the Reverse Packets from IPv6 Network thru IPv4 Cloud to IPv6 Network Packets from IPv4 Network thru IPv6 Cloud to IPv4 Network Page 7

10 Deployment Roadmap Model ERM Masters 2002 Step 1 - Determine the set of network applications that must be ported or invented (where packets go over the network) Step 2 Determine the Geography your applications must span. Step 3 Identify the Network components that must support IPv6. Step 4 Identify the Network components that require IPv6 Transition Mechanisms. Step 5 Identify the Network components that are new or being developed and can be initiated with IPv6 using IPv4 as scarce resource only, especially new technology deployment models (e.g. Network War Fighter, Mobile IP Networking Components, New Simulation Programs, Home Land Defense Surveillance) Page 10

11 Deployment Transition MechanismsERM Masters 2002 Configured Tunnels Base IPv6 Transition Spec Dual IP Layer Model 6to4 Gateways ISATAP Pseudo Tunnels (Clients, Servers, Routers, and Gateways) Dynamic Tunnels to avoid IPv6 and IPv4 NATs DSTM Dynamically Assigning Tunnel Endpoints Dynamically Assigning Temporary Global IPv4 Addresses Pseudo Tunnels (Clients, Servers, Routers, and Gateways) Teredo to bypass IPv4 NAT and using 6to4 Page 11

12 ERM Masters 2002 Deployment Transition Mechanisms (continued) Network Translation (the last alternative) NAT-PT (stateful translator) SIIT (stateless translator) IPv6-ONLY to IPv4-ONLY Communications Routers and Gateways Basic and Advanced API and Bump-in-the-API Mechanisms Port Applications to use IPv4 and IPv6 communications Port Applications to use IPv6 communications where IPv4 is represented as IPv6 Bump-in-the-API mechanisms for Software where the sources are lost or so old reporting them is not an option and they must be replaced eventually!!!! Recommended as last resort only!!!! Page 12

13 Transition Hot Spots ERM Masters 2002 Wireless Communications and integration with Wireline (Broadband) Communications Mobile IP for Cellular Handoffs and Mobile Ad-Hoc Routing Application Porting Methodology Tunnels around IPv4 encryption-devices that cannot be upgraded to IPv6 immediately and performance of that tunnel Use of AAA Servers and Clients for initial security and tracking (Ethernet, , 3G, PPP-over-Ethernet (PPOE)) Cost is mostly people investment and training, not software, and some hardware. Europe + Asia adoption exceeds the U.S. and this will affect the initial transition mechanisms vendors engineer first. Key Management for IPsec and Public Key Infrastructure Page 13

14 Impact of Transition on the DoD ERM Masters 2002 Internet infrastructure will be done by the vendors as off the shelf commercial transition tools. Determine the network applications that are needed to be ported or invented. Determine the Geographical scope within the Network Nodes and Software required for the scope. Transition Mechanisms have a dependence on critical execution points where transition occurs. For applications that are DoD geographic specific you may want to assume IPv6 ONLY communications (this does not mean you cannot have dual IP layer) Page 14

15 ERM Masters 2002 Impact of Transition on the DoD (continued) Need to determine methodology for porting applications. Need to determine if Dual IP layer support is required for all DoD nodes. Need to consider more of the leading edge issues for IPv6 like Mobile Ad-Hoc Networking Most cost will be in requirements definition, planning, system analysis, and training of personnel. Wireless and Wireline will use different transition mechanisms. Page 15

16 Current IPv6 Deployment State ERM Masters 2002 Asia is leading the pack geographically, deploying high tech devices, wireless, and wireline IPv6 infrastructure. European and Asian High-Up Officials within Government have made formal statements regarding the importance of IPv6. 3G has still not produced IPv6 deployment but is in waiting Wi-Fi is potential High End Deployment for IPv6 and Mobile IPv6: First with reconnect strategy when roaming Then Mobile IPv6 always-on-anytime roaming U.S. is still lagging in industry but DoD is leading with work at SPAWAR CECOM at FT Monmouth, DISA, OSD, and other activities Good News: All major vendors have shipped first and second version of IPv6 Products. ISPs worldwide are beginning to do trials with IPv6 (including the U.S.) Early Adopters worldwide have procured systems to begin to build IPv6 labs and test beds. North American IPv6 Task Force (NAV6TF) is established and in process. Page 16
