12:00am - 12:00am	Commonwealth B/C	Tutorial: Introduction to Shell and Perl Scripting for Network Operators Being able to develop or customize simple tools using simple shell or Perl scripts is a skill all network operators should possess. This tutorial will examine a set of scripts, progressing from the simple to the more complex, which will be used to introduce newcomers to the fine art of tool hacking. While this tutorial is too short to comprehensively cover programming and the nuances of the tools available, newcomers can expect to come away with enough knowledge to start hacking their own useful tools, or to make use of the examples provided as a foundation towards something even more useful in their own real networks.

12:00am - 12:00am	Commonwealth D	Tutorial: You Can't Do That With nslookup: DNS(SEC) Troubleshooting Troubleshooting DNS before DNSSEC was hard enough, and it was made more difficult when people tried to troubleshoot complex DNS problems using old tools like nslookup. With DNSSEC, the number and complexity of DNS issues makes it imperative that DNS admins understand how to use the tools available to them. This tutorial explains how to use (and interpret) tools like dig, dnscap, dnsviz, and others. It covers these specific topics (not necessarily in this order or structure): Basic DNS troubleshooting with dig, Visualizing DNSSEC with dnsviz, dnscap and nmsg: Specialized packet capture tools for DNS and what they can do for you, Understanding the troubleshooting process and troubleshooting hard issues.

9:00am - 10:00am	Commonwealth D	Tutorial: Introduction to DNSSEC I propose to teach my approximately one-hour DNSSEC introductory class. This is the same tutorial I taught at NANOG51 in Miami. The class covers the motivation for DNSSEC and an overview of how it works, down to the level of individual DNS resource records. It's comprehensive but not overwhelming: I believe it's very understandable. Students need to know what public/private key cryptography and digital signatures are, or they'll be a bit lost, and a very high level understanding of DNS would be helpful, too (e.g., knowledge of what a zone is). There's probably a nicer-looking abstract than this one already on file from NANOG 51... The tutorial went well last time and I'd enjoy teaching it again. View full abstract page.

12:00am - 12:00am	Millennium Hall	95th Percentile Billing Monthly 95th percentile billing to internet access customers, such as CDN providers, is a standard practice by backbone internet service providers. The 95th % value has traditionally been used for billing so that customers are not overcharged for transient bursty data traffic. This 'burstable billing' practice is more favorable to customers with less peaked traffic. If the peak to mean ratio is significant, then the overall price per unit volume transferred increases. Internet traffic time of day patterns are currently peaked due to the popularity of bandwidth intensive video applications in the evening. Is 95th% billing compatible with peaked video traffic? Consumers are starting to pay for internet service based on volumes consumed. Might alternative pricing structures provide more transparency with respect to price per unit volume for both customers and providers? This analysis will provide an in depth examination of sample traffic data subject to 95th % measurement and consequences of this billing approach. View full abstract page.

12:00am - 12:00am	Millennium Hall	Broadband Internet Performance: A View from the Gateway We present the first study of network access link performance measured directly from home gateway devices. Policymakers, ISPs, and users are increasingly interested in studying the performance of Internet access links. Because of many confounding factors in a home network or on end hosts, however, thoroughly understanding access network performance requires deploying measurement infrastructure in usersâ€™ homes as gateway devices. In conjunction with the Federal Communication Commissionâ€™s study of broadband Internet access in the United States, we study the throughput and latency of network access links using longitudinal measurements. We study the performance users achieve and how various factors ranging from the userâ€™s choice of modem to the ISPâ€™s traffic shaping policies can affect performance. Our study yields many important findings about the characteristics of existing access networks. Our findings also provide insights into the ways that access network performance should be measured and presented to users, which can help inform ongoing broader efforts to benchmark the performance of access networks.

12:00am - 12:00am	Millennium Hall	Keynote - Dave Ward The network holds critical and valuable information needed to influence user experience. The capability of incorporating real-time network analytics and programming the internet is rapidly emerging in new toolchains for application developers. This enables open application models and development platforms that use many new orchestration systems. The amount of information available for use by applications to deliver fine-tuned experiences is going to be commonplace in these leading edge software platforms. This access to network information offers developers more opportunity for value and differentiation in their applications and services. The first movers to understand this will have vast advantages over others. In this keynote, David Ward, Chief Architect & CTO of the Platform Systems Division at Juniper will dig into the architectures, protocols and platform landscape. He will discuss the role that emerging technologies like OpenFlow can and will play, highlighting the additional technology pieces required to deliver a programmable network. View full abstract page.

12:00am - 12:00am	Millennium Hall	Analyzing the Effectiveness of the CIDR Report Many network operators seem to have an opinion about the effectiveness of the CIDR Report -- typically that it was once effective, but has dropped off over time for various reasons. Beyond opinion, however, there has never been ananalysis of whether the CIDR Report actually induced behavior changes in the ASes featured on the "top 30" list that we receive each Friday. This work presents an analysis of the effectiveness of the CIDR Report as an effort by the Internet operations community to encourage route aggregation. It also contains a number of observations about the CIDR Report and how it could potentially be changed to focus on behavior that might yield improvement. View full abstract page.

12:00am - 12:00am	Millennium Hall	How Many Tiers? Pricing in the Internet Transit Market ISPs are increasingly selling "tiered" contracts, which offer Internet connectivity to wholesale customers in bundles, at rates based on the cost of the links that the traffic in the bundle is traversing. Although providers have already begun to implement and deploy tiered pricing contracts, little is known about how to structure them. Although contracts that sell connectivity on finer granularities improve market efficiency, they are also more costly for ISPs to implement and more difficult for customers to understand. Our goal is to analyze whether current tiered pricing practices in the wholesale transit market yield optimal profits for ISPs and whether better bundling strategies might exist. In the process, we offer two contributions: (1)~we develop a novel way of mapping traffic and topology data to a demand and cost model; and (2)~we fit this model on three large real-world networks: an European transit ISP, a content distribution network, and an academic research network, and run counterfactuals to evaluate the effects of different bundling strategies. Our results show that the common ISP practice of structuring tiered contracts according to the cost of carrying the traffic flows (eg{}, offering a discount for traffic that is local) can be suboptimal and that dividing contracts based on {em both traffic demand and the cost of carrying it} into {em only three or four tiers} yields near-optimal profit for the ISP.

12:00am - 12:00am	Millennium Hall	The Impact of IPv4/IPv6 Interworking on Lawful Intercept The introduction of IPv4/IPv6 interworking has disrupted the end-to-end lawful intercept model because it results in both IP versions in one communication session. This requires reporting headers of IPv4 and IPv6 in the same CACmII message, which is not allowed by the standards. For reporting CACmII, IASPs are faced with the technical challenge of how to best restore and report the original traffic characteristics of the target under surveillance which are altered and/or hidden by the transition mechanisms. This presentation provides an impact analysis of two transition mechanisms on the reporting of CACmII. It also identifies possible solutions and open questions for each solution. The goal of the presentation is to stimulate effective brainstorming on the topic. View full abstract page.

12:00am - 12:00am	Millennium Hall	Economics of IPv4 Address Markets on IPv6 Deployment Economic concepts underpin many of our day-to-day relationships. This presentation looks at the some of the economic concepts underneath the IPv4 transition, IPv6 deployment, and specifically how the creation of an IPv4 transfer market will effect IPv6 deployment. The lack of easily available IPv4 numbering resources and the lack of IPv6 compatible networks could cause a number of changes to the Internet including limiting growth, changing overall architecture, and restricting free information access. Here we look at some of these concepts and propose some hypotheses of the transition based upon economic models. View full abstract page.
