Abstract: Mobile infrastructure (e.g. 3G packet core) has been something most at NANOG could ignore -- different groups, closed networks, somebody elses problem. But as mobile traffic looks to overtake fixed line and carriers merge their fixed and mobile engineering / security groups,<BR> mobile trends become a bit more important.<BR> <BR> This talk provides an overview mobile infrastructure traffic and security trends. Specifically, we use data from ATLAS self-classified mobile providers, a detailed security survey of 117 carriers around the world, instrumentation of 30,000 handsets and extensive 3G / 4G lab tests to survey the state of traffic and security trends in mobile networks.

Jan Schaumann, Yahoo!

Jan Schaumann is a Systems Architect at Yahoo!, a nice place to stay on the internet, and an Adjunct Professor of Computer Science at Stevens Institute of Technology, teaching classes in System Administration and UNIX Programming. He remains continually astonished that the internet at large does not break down spectacularly on a regular basis. Jan can be<BR> reached at: jschauma@yahoo.com
Abstract: Direct Server Return (DSR) load balancing is a common way to distribute network traffic using an approach that currently requires the load balancer and all hosts behind the Virtual IP (VIP) to be within the same Layer 2 network. This is a severe limitation that hinders scaling VIPs beyond a single contiguous subnet. In this paper, we present a method to perform DSR load balancing across Layer 3 boundaries (``L3DSR''), a solution allowing us to serve up to ten times as many VIPs on a single hardware Load Balancer compared to other Layer 3 load balancing methods. This technology has been developed and implemented in-house together with our hardware vendors and internal software development teams. We plan on open sourcing the relevant code on the server side in the near future.

Presenters: Speakers:

Rob Shakir, Cable&Wireless Worlwide

Rob works within the Network Design team in Cable&Wireless Worldwide, with a direct involvement in the architecture and design of global MPLS/IP platforms. His previous roles have been in operational teams - with experience in both network and hosting service providers. Rob maintains a strong interest in improving network protocols to meet the demands of operator networks, and is a regular contributor to various forums on this subject, with a particular focus on BGP-4.
Abstract: BGP-4 is utilised as a key intra- and inter-Autonomous System routing protocol in modern IP networks. The failure modes as defined by the original protocol standards are based on a number of assumptions around the impact of session failure. Numerous failures, both within the Internet, and Service Provider networks have resulted in reacting to errors in a single UPDATE message resulting in large-scale failures in one or more Autonomous Systems' IP network.<BR> <BR> This presentation intends to support a draft describing the current use of BGP-4 within Service Provider networks, and outlining a set of requirements for further work to enhance the mechanisms available to a BGP-4 implementation when erroneous data is detected.<BR> <BR> It is intended that the draft supported by this presentation is reflective of operator's requirements, based on their BGP deployments, and forms a basis for an approach to BGP error handling enhancements.

Keyur Patel, Cisco.
Abstract: It is well known that a relatively small percentage of unstable routes exists in the global routing system which contributes an out of proportion number of routing updates. The route flap damping (RFD) was once considered an effective means to curtail such instability. However, both measurement studies and operational observations show that BGP path exploration can trigger false route damping which leads to prolonged periods of lost network reachability. As a result, many networks turned off RFD. In this paper we propose a simple solution, RFD+RG, dubbed RFD with Reachability Guard, to address the reachability problem in the RFD deployment. RFD+RG performs route flap damping without losing reachability, and the +RG enhancement component works independently from specific damping algorithms and can be integrated into any existing RFD scheme. We use collected BGP data to evaluate RFD+RG performance and our results show that RFD+RG can suppress up to 27% of route instabilities while faithfully preserving reachability.

BGP churn evolution: A perspective from the core
Meeting: NANOG51
Date / Time: 2011-02-01 12:30pm - 1:00pm
Room: Grand
Presenters: Speakers:

Ahmed Elmokashfi, Simula Research Laboratory

Ahmed Elmokashfi is a Ph.D student at Simula Research Laboratory and University of Oslo. He received his B.Sc. degree in Electrical and Electronics Engineering from the University of Khartoum in 2003, and his M.Sc degree in Telecommunication form Blekinge Institute of technology <BR> in 2007. Elmokashfi research interests include IP routing, routing scalability, measurements, and network science.
Abstract: The scalability limitations of BGP have been a major concern in the networking community lately. An important issue in this respect is the rate of routing updates (churn) that BGP routers must process. This work presents an analysis of the evolution of churn in four networks in the backbone of the Internet over a period up to seven years and eight months, using update traces from the Routeviews project. The churn rate varies widely over time and between networks, and cannot be understood through “black-box” statistical analysis. Instead we take a different approach with a focus on investigating the underlying reasons for BGP churn evolution. Through our analysis we are able to identify and isolate the main reasons behind many of the anomalies in the churn time series. We find that duplicate announcements is a major churn contributor, and responsible for most large spikes in the churn time series. Other intense periods of churn are caused by misconfigurations or other special events in or close to the monitored AS, and hence limiting these is an important mean to limit churn. We then analyze the remaining “baseline” churn, and find that it is increasing with a rate much slower than the increase in the routing table size.

Quantifying the Impact of DNSSEC Misconfiguration
Meeting: NANOG51
Date / Time: 2011-02-01 3:30pm - 4:00pm
Room: Grand
Presenters: Speakers:

Casey Deccio, Sandia National Laboratories

Casey Deccio is a Senior Member of Technical Staff at Sandia National Laboratories in Livermore, CA. He joined Sandia in 2004 after receiving his BS and MS degrees in Computer Science from Brigham Young University, and he received his PhD in Computer Science from the University of California, Davis in 2010. Casey's research interests lie primarily in modeling and availability analysis of DNS and DNSSEC, and he leads Sandia's DNSSEC deployment efforts.
Abstract: Deployment of the DNS Security Extensions (DNSSEC) has increased significantly in the last year. A number of top-level domains have also been signed in the last year, and a major milestone was reached with the signing of the root zone in July, 2010. However, the complexity introduced by DNSSEC has made its deployment non-trivial, and DNS administrators have felt the effects of DNSSEC misconfiguration, whether by expiring RRSIGs, DS RR mismatch, path MTU (PMTU) issues, or other causes. In this presentation, we categorize DNSSEC misconfigurations, introduce metrics for quantifying their impact on availability, and introduce methodology for mitigating their effects.

DNS Query Sent by Heavy Users and DNS Prefetch Effect
Meeting: NANOG51
Date / Time: 2011-02-02 10:30am - 11:00am
Room: Grand
Presenters: Speakers:
Kazumichi Sato, NTT.
Abstract: DNS queries from users have been increasing. We found that number of heavy users sent large number of queries increased during 2009 and 2010. Moreover, we found that number of heavy users who use Firefox increased.<BR> <BR> We suspect that DNS prefetch increased number of heavy users. DNS prefetch is function that resolves domain names included in URLs in the browsed WEB page. Google Chrome, Firefox, and Safari implement DnS prefetch.
