Some notable projects include PeeringDB, a portal used by many networks to help coordinate their peering activities, and IRRPT, a software package used by ISPs to maintain IRR-based prefix filters.
Abstract:	A completely practical step by step guide to configuring IPv6 in a production network without breaking anything, for people who hate IPv6 and don't have it deployed currently. The goal would be that everyone who leaves the room should be able to successfully deploy an IPv6 network on top of an existing v4 network on any common Juniper/Cisco hardware, without needing to be IPv6 experts or lovers of the protocol. I also want to talk about practical techniques for addressing management so you can successfully deploy IPv6 without having successfully rewritten all of your internal management tools to fully support it, and other tricks to minimize the pain.

Tutorial: Network Capacity RFP: What, Why, How-To
Meeting:	NANOG46
Date / Time:	2009-06-14 4:00pm - 5:30pm
Room:	Regency Ballroom, 2nd FL Mezz
Presenters:	Speakers: Martin Hannigan, None Martin Hannigan is long time Internet network builder. Circa ~88, his past includes early development of networks and products at Bose Corporation, Microsoft, Level(3) Communications, VeriSign, and Verne Global ehf. He's currently the market go-to person and a founder of the burgeoning Iceland Data Center industry, consults for the largest ILEC in the Caribbean, and is appointed to the ICANN ASO AC by the ARIN Board of Directors. He participates in development of global IPv4 and IPv6 network numbering policy matters representing North America. He's an attendee of ARIN, RIPE, LACNIC, AFRINIC, NANOG, UKNOF, IETF, and other industry community gatherings.
Abstract:	The network capacity purchasing RFP can be a powerful tool that insures all options are on the table during pricing negotiations. It also allows the purchaser to remain firmly in control of the process. We aren't buying used cars, we're subscribing to radically changing costs that need to be managed closely. In this talk we will take a mid level walk through a tested RFP and discuss different aspects of an effective request for pricing or proposal "RFP". We will discuss how defining needs over multiple years can be strategically related to discounts and pricing, how to ask providers to define their own service delivery needs so you can recoup costs and standard terms and conditions to minimize lawyer time and expense. We'll conclude with a walk through of an actual RFP that will be provided as a template for later use.

Rapid Convergence in IP Networks
Meeting:	NANOG46
Date / Time:	2009-06-15 12:30pm - 1:00pm
Room:	Regency Ballroom, 2nd FL Mezz
Presenters:	Speakers: Tom Scholl, AT&T Labs Within the Global IP/MPLS backbone design & development team, his role is to design routing architectures for the core network and work on network integration of the legacy SBC Internet Services network to the AT&T common backbone. Tom has spent his last several years at SBC and Ameritech working in both operations and network engineering roles. He has presented several times at NANOG and always makes time available to help peers and distribute clue where needed.
Abstract:	This presentation covers the topic of rapid convergence within IP networks. IP networks are frequently stated to not be capable of providing rapid convergence similar to that of SONET transport networks. However, with the right knob turns and a properly designed network, you can reach that 50ms or at least sub-second convergence target. The presentation will outline what applications require such performance, what protocols can deliver the results and how well it actually works in production. Additional lessons learned will be outlined showing operators that its not as simple as flipping on a switch. A list of commands and knobs are given at the end of the presentation to get operators a starting point to improve performance within their own networks.

Room:	Regency Ballroom, 2nd FL Mezz
Presenters:	Speakers: Luca Martini, Cisco.
Abstract:	Pseudowires where invented during the latest Tech boom in late 1999 out of necessity of replacing ATM networks with a more efficient technology. The technology quickly became very popular, and enabled new services like VPLS, and VPWS, while offering a cost effective solution for metro access aggregation, and mobile aggregation. Today, 10 years later, Pseudowires seem to be taking over the traditional SONET/transmission world not by emulating SONET, but by replacing it! This talk will explore the history, and reasoning behind the PW design, deployment experience, and future evolution of the technology.

Abstract:	Software bugs in routers lead to network outages, security vulnerabilities, and other unexpected behavior. Rather than simply crashing the router, bugs can violate protocol semantics, rendering traditional failure detection and recovery techniques ineffective. Handling router bugs is an increasingly important problem as new applications demand higher availability, and networks become better at dealing with traditional failures. Further demonstrating the importance is a string of recent high profile outages, including a very recent incident where a single prefix announcement to a single provider caused a huge increase in the global update rate and instability due to two bugs in routers from two different vendors. In this paper, we tailor software and data diversity (SDD) to the unique properties of routing protocols, to avoid buggy behavior at run time. Our bug-tolerant router executes multiple diverse instances of routing software, and uses voting to determine the output to publish to the forwarding table, or to advertise to neighbors. We design and implement a router hypervisor that makes this parallelism transparent to other routers, handles fault detection and booting of new router instances, and performs voting in the presence of routing-protocol dynamics, without need to modify software of the diverse instances. Experiments with BGP message traces and the XORP and Quagga open-source software running on our Linux-based router hypervisor demonstrate that our solution scales to large networks and efficiently masks buggy behavior.

Tutorial: Introduction to DHCPv6 and DHCPv6 for DOCSIS
Meeting:	NANOG46
Date / Time:	2009-06-16 4:30pm - 6:00pm
Room:	Regency Ballroom, 2nd FL Mezz
Presenters:	Speakers: John Brzozowski, Comcast At Comcast, John provides technical leadership and guides the firm's deployment of IPv6. He leverages his expertise and experiences to drive the adoption and implementation of IPv6 ensuring that innovative solutions are in place to support traditional and next generation services. John has contributed significantly to many standards and technologies critical to the cable industry's adoption of IPv6, specifically those pertaining to voice, video, and data. He works closely with CableLabs on DOCSIS and PacketCable specifications and has contributed to IETF standards efforts.<BR> <BR> John's work in the technical community currently includes acting as the chair of the MidAtlantic IPv6 Task Force, North American IPv6 Task Force Steering Committee member, and member of the IPv6 Forum. Through his work with these organization he helps to drive and support critical IPv6 activities regionally and nationally including but not limited to promoting IPv6 education, awareness, and of course adoption. John also serves as co-chair of the IETF DHC Working Group and co-chair of the MAAWG IPv6 technical sub-committee.
Abstract:	This session is intended to provide an introduction to DHCPv6. DHCPv4 and DHCPv6 are separate and distinct protocols. DHCPv6 will be compared and contrast to DHCPv4, specific topics include techniques that can be used to offer redundant DHCPv6 services in the absence of a standards based protocol. Additional topics related to the evolution and future use of DHCPv6 will also be discussed. Further, current applications of DHCPv6 will also be discussed specifically the use of DHCPv6 in DOCSIS networks to support the deployment of IPv6. Deployment and migration techniques will also be discussed at a high level.

IPv6 Deployment on a Broadband Access Network
Meeting:	NANOG46
Date / Time:	2009-06-17 10:30am - 11:00am
Room:	Regency Ballroom, 2nd FL Mezz
Presenters:	Speakers: Athanasios Douitsis, National Technical University of Athens Athanasios Douitsis graduated from the Department of Electrical and Computer Engineering of the National Technical University of Athens in 2000 and is currently a Ph.D. candidate at the Network Management and Optimal Design Laboratory at NTUA. He has been working for the NTUA Network Operations Center since 2000, involved in the development and administration of the NTUA campus network, the Greek Research Network (GRNET), the Greek School Network and the Greek Student Network. He has experience in Network Management, Monitoring and Measurements, Multicast, IPv6, VPNs, WDM/SDH and System Administration.
Abstract:	In our presentation, we would like to share the experience gained by carrying out the early phases of IPv6 testing and limited deployment in the Greek Student Network (Diodos). Diodos is a state sponsored ADSL access network that is operated by the Greek Research Network and provides network access to academic users across the country. With 50 institutions involved and more than 20000 academic users connected, assigning IPv6 prefixes to each user according to the respective institution presents some interesting addressing and routing problems, which we describe in detail and propose our solution. Furthermore, we describe the use of PPPv6, DHCPv6 prefix delegation or other possible options to enumerate the LAN behind each user CPE and we elaborate on RADIUS AV pairs, accounting problems, DNS options, ACLs, implementation availability, critical bugs and various miscellaneous details for Cisco based equipment. Lastly, we describe the state of our testing deployment and lay out the problems that are critical and must be addressed in the future.

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.
