Meeting: NANOG46
Date / Time: 2009-06-17 11:30am - 12:30pm
Room: Regency Ballroom, 2nd FL Mezz
Presenters: Moderators:

David Ward, Cisco Systems

Dave Ward is a Distinguished Engineer and software geek at Cisco Systems. He is the software architect for IOS-XR, Cisco's next-generation operating system, and co-system architect of the CRS-1 multi-terabit router. Dave is also the chair of the IS-IS, HIP and BFD Working Groups at the IETF, and a member of the IETF-ITU ASON design committee.
Panelists:

Alain Durand, Comcast

Alain has been working on IPv6 since 1994, participated in the INRIA BSD IPv6 implementation in 1995, and was a pioneer on the 6bone in 1996. He has authored numerous RFCs and Internet Drafts, and co-chaired the IETF NGtrans working group from 1999 to 2002. He now servers as the co-chair of the Softwires working group. Prior to Comcast, Alain was at Sun as the IPv6 architect during the development of Solaris 10.
Suzanne Woolf, Internet Systems Consortium.

Lixia Zhang, UCLA

Lixia Zhang is a Professor in the UCLA Computer Science Department. She received her Ph.D. degree from MIT in 1989. Lixia was a research staff member at Xerox PARC from 1989 to 1995, when she joined UCLA. Her recent research projects have focused on fault tolerance in large-scale systems and network routing protocols.

Chris Chase, AT&T Labs

Chris Chase is a Fellow at AT&T Labs. At AT&T Chris has been anarchitect for the Frame Relay and ATM networks and the chief architect of AT&T's industry first BGP/MPLS VPN for which he also developed tools for MPLS VPN routing and monitoring. More recently he was a network architect for AT&T U-Verse delivering triple play service over next generation broadband. Currently, he is leading efforts on analysis and scaling for broadband and mobility data services. Chris has a PhD in electrical engineering from Princeton University.
Abstract: Address family translation is being discussed as a viable strategy to deal with IPv4 address exhaustion and IPv6 transition. In the former sense, it can be used to allocate private addresses to customers of a service provider as the NAT is under the provider's control. In the V6 transition case it is seen as a method for either allocating V6 addresses to subscribers when the provider network isn't fully V6 enabled or when a provider's network is V6 enabled and a subscriber is not V6 ready. No matter how one view's NATs there is renewed interest in deploying much larger NATs that perform multiple functions. There are a couple of critical items in this round of deployment: they may be deployed under the provider's control and there may be conjoined encapsulation technology.



This panel will discuss why SP based NATs are interesting again and go over many deployments, advantages of the technology, costs, operational considerations and anticipated longevity in the network. Given there is much experience with NAT, the panelists will openly discuss the pros and cons and why they need to be taken very seriously as a deployment strategy.
