Full AbstractThe tutorial introduces service providers to some more advanced BGP features and techniques to aid with operating their networks within the Internet. After a recap of iBGP, eBGP and common attributes, the tutorial will look at the various scaling techniques available, when to use BGP instead of an IGP, and examine policy options available through the use of local preference, MED and communities. The tutorial then looks at deployment techniques, including aggregation, announcing and receiving prefixes, pressure points on the routing system, AS-origin validation, and some of the newer features available. This is an updated version of the tutorial under the same title presented by Philips Smith in previous NANOG sessions. Speakers |

RecordingsFull AbstractOnline service providers continually aim to provide good performance for an increasingly diverse set of applications and services. Network routing attempts to improve performance by selecting a good route between a customer and provider. Content routing attempts to move content closer to customers by replicating content and redirecting traffic to closer replicas. These two methods are largely agnostic of each other today. In this talk, we consider the benefits of extending Content routing using network routing. We emulate a system that controls both replica selection ("content routing") and the routes between the clients and their associated replicas ("network routing"). We find that joint routing yields an additional 4% reduction in latency as compared to content routing, and that the majority of these gains can be realized with no more than five alternate routes at each replica.

RecordingsFull AbstractThe RPKI is the infrastructure under BGP origin validation, and therefore its propagation characteristics and reliability are of concern. Two studies are presented, one assessing the performance and reliability of the early deployments of RPKI publication and the other a medium-scale emulation of large scale deployment of the RPKI. Together, they tell an interesting story of what we have today and what we can expect in the future. Speakers |
Full AbstractAs IPv6 and the Internet of Things finally become operational reality, home and SOHO networks are beginning to see additional pressures to become more complex. The need for separation of visiting guest users from home users, community Wi-Fi services, smart grid, home automation & security, and an ever increasing number and type of IP enabled devices in the subscriber home are all strong motivations for additional routers and multiple LANs. The removal of NAT and the emergence of heterogeneous link layer technologies, machine to machine communication, IP & multicast video streaming, video content sharing inside the home, telecommuting and corporate IT requirements, and the possibility of home network multi-homing are all also driving additional complexity and new requirements into home networks. Unfortunately, service providers and corporate IT departments can not count on end users becoming any more network savvy than they are today. This presents a unique problem space for the future development of home network technologies and architectures. This talk will explore several of the key challenges, assumptions and use-cases for the home network of tomorrow, setting the stage for future development and innovation. Speakers |
Full AbstractThe NLNOG RING is a collaboration of a growing number of organisations (110+ organisations in 26 countries as of August 2012) to troubleshoot and debug networks in a more efficient and flexible way than previously possible. The RING provides operators with a view from the outside and powerful tools to accomplish in mere seconds what would otherwise take days. The RING is entirely built by a thriving community of volunteers, organisations can join free of charge, as such the RING is unique and the world's first of this kind. The audience will learn what the RING is and demonstrations will be given how common troubleshoot scenarios can be tackled with the RING. A word of caution: the RING is an immensly versatile tool and its ease of use might be shocking. Speakers |

Full AbstractThe Internet plays a key role in our everyday lives. The public sector faces a challenging role when critical infrastructure is actually under the operational control of private enterprises. The best approach in this scenario is to facilitate the development of technologies, processes and information sharing that can help improve the security posture of private enterprises and to help raise the awareness within various industries regarding the need to improve the security posture of critical infrastructure. The goals of the Cyber Security Division (CSD) within the Science and Technology Directorate of DHS are threefold: 1) To perform research and development aimed at improving the security of existing deployed technologies, and to ensure the security of emerging systems; 2) To develop new and enhanced technologies for the detection of, prevention of, and response to cyber-attacks on the nation's critical information infrastructure; and 3) To assist in the transfer of these technologies into the national infrastructure. In this talk I will highlight some of the key ongoing initiatives of operational and strategic value to the Internet operations community such as RPKI/BGPSec, DNSSEC, Internet measurement, as well as research initiatives such as PREDICT, DETER, SWAMP and other transition projects targeted specifically at helping research technologies cross the valley of death.

RecordingsFull AbstractThe AMS-IX will probably run out of its /22 IPv4 address space on the Internet Peering VLAN in 2016. It is uncertain if a larger IPv4 address block is available at that time. RFC 5549 describes how MP-BGP can be used to advertise IPv6 next hop addresses for IPv4 routes. This would eliminate the need for IPv4 entirely on the AMS-IX Internet Peering network. This presentation is an introduction to RFC 5549 and shows a proof of concept implementation. Speakers |
RecordingsFull AbstractResearch on interdomain routing often requires models of BGP routing policies. However, the state-of-the-art BGP routing policy models, that are used by most researchers, have now been around for more than a decade. Do the assumptions made in these models make sense, or have things changed? To answer this question, we ran a preliminary survey on the routing policies used by 100 network operators. In this short talk, we'll present the results of this survey, and solicit more feedback from network operators so that we can develop more accurate models. We hope this short talk will spur lively discussion from NANOG participants, and inform the questions we ask and the models we develop in future studies of BGP routing. Speakers |
Full AbstractWe present CAIDA's AS-rank project, a macroscopic ranking of ASes based on a measure of their influence in the global routing system by inferred customer cone size. The customer cone represents the fraction of ASes in the Internet that an AS can reach and be paid for transiting traffic to and from. Constructing the customer cone requires a reliable set of business relationship inferences. This talk presents our methodology for inferring business relationships from public BGP data, our validation efforts for the relationship inferences that have been aided immensly by operator feedback, and our methodology for inferring the customer cone of each AS. We present analyses of the rankings of ASes over time. Speakers |
Full AbstractIEEE 802.3 released the Bandwidth Assessment Report in July that quantifies bandwidth trends for many key applications. The communications industry is seeing unprecedented growth as more applications send more data to more users at higher speeds for longer times. This virtuous cycle of providing better services at lower cost causes larger consumption of data that drives the need for more bandwidth. With users already lagging multiple 100 Gigabit Ethernet links, IEEE 802.3 is building consensus on the next speed of Ethernet in the new Higher Speed Ethernet (HSE) Consensus Industry Connections. Come and hear the discussion between the President and Chair of the Ethernet Alliance over what the next speed of Ethernet should be. This is your opportunity to voice your needs and concerns for the Ethernet Alliance to gather and bring to the IEEE. Speakers |

Full AbstractFor any operator today, it is not enough to be able to manage just their segment of the network (access, middle-mile or last-mile). Rather, with the diversity of applications and services, and the growth in mobile broadband in the first mile and data centers in the last mile, it is imperative for an operator to have cross-domain insights. Thus, an operator must not only know the performance of the network (latency, jitter, delay, loss, throughput/bandwidth, and availability) locally, but also how these parameters are affected by adjacent network segments, and how the network behavior, as a whole, affects application performance. While much has been discussed in various forums about application performance, there can be no application performance without sound network performance! Thus, network performance or activities that are needed to keep the network up and running, reliably and efficiently, are critical, especially in today’s dynamic networks. E.g. sync. distribution in 3G and 4G/LTE mobile backhaul networks, impairment detection, and fault isolation & notification to name a few. In this panel, we will, therefore, discuss end-to-end performance management & monitoring with a focus on network-level problems and measurements. That is, we will consider the (horizontal) interactions between providers in different segments – access, middle-mile and last mile, and issues of sharing metrics across operator boundaries, which metrics are critical for network performance and why, and at how performance problems can be fixed efficiently and speedily. It turns out that while there are many tools and techniques for performance management (advanced OAM, better sampling & aggregation methods, synthetic transactions, support in vendor systems, and sophisticated software), it is still very tricky to answer fundamental questions such as: where did a performance problem originate? who is responsible for it? how do we go about fixing it? The current panel will bring together key players from the carrier eco-system to discuss, debate, and answer important questions on network-centric performance management, such as: i) What are key advances in performance monitoring of fundamental network-level activities that enable the proper & efficient running of a network? ii) Which advances are designed to enable proactive performance management, as opposed to reactive performance management? iii) Where are we on the ownership and sharing of performance data – how could operators in different segments share this data (without revealing internal details)? What is making this a necessity in today’s environment? What changes are occurring (in operator practices, vendor offerings, and software solutions) to facilitate that? iv) What is the role of standardization in enabling the industry to converge on performance management capabilities? v) What are the advances in real-time collection and processing of data, and how do they aid performance management in today’s complex IP/Ethernet networks? vi) With network complexity and scale, automated network enforcement actions could be valuable. However, they are perceived as complicated and risky. What is the eco-system doing to facilitate these? Why or why not? vii) How does fault isolation across boundaries work? How is fault notification done? How does one determine and assign “responsibility†to the liable network segment/operator? viii) Are some of the ensuing difficulties merely organizational? Or, are there limits from software and systems? If the latter, what is the eco-system doing to remove those? ix) What is the contribution of the network (or a network segment) to application performance? How does advanced system design enable an operator to better determine/track that?

Full AbstractTracking the use of DNSSEC by the TLD registries (root zone plus the immediate delegations) to detect how DNSSEC has been implemented (or not) has led to the "usual" survey of a new technology and insight into the rate of deployment. More interestingly, what has come to light is the divide between what protocol engineers (via the IETF documents) expected to happen and what the operators have come to develop. In some cases there is close coupling with RFC recommendations, in others there is a diversion. Speakers |
RecordingsFull AbstractThe fast growth of global routing table size has been causing concerns that the Forwarding Information Base (FIB) will not be able to fit in existing routers’ expensive line-card memory, and upgrades will lead to higher cost for network operators and customers. FIB Aggregation, a technique that merges multiple FIB entries into one, is probably the most practical solution since it is a software solution local to a router, and does not require any changes to routing protocols or network operations. While previous work on FIB aggregation mostly focuses on reducing table size, this work focuses on algorithms that can update compressed FIBs quickly and incrementally. Quick update is critical to routers because they have very limited time to process routing updates without impacting packet delivery performance. We have designed three algorithms: FIFA- S for smallest table size, FIFA-T for shortest running time, and FIFA-H for both small tables and short running time, and operators can use the one best suited to their needs. These algorithms significantly improve over existing work in terms of reducing routers’ computation overhead and limiting impact on the forwarding plane while maintaining good compression ratio.
