DTSTART;VALUE=DATE-TIME:20190218T183000Z DTEND;VALUE=DATE-TIME:20190218T190000Z DTSTAMP;VALUE=DATE-TIME:20191029T155742Z UID:1880 CONTACT:Alex Band CONTACT:Martin Hoffmann DESCRIPTION:Speaker: Alex Band\, NLnet Labs\nSpeaker: Martin Hoffmann\n\nS ince 2011\, the five RIRs have been offering Resource Public Key Infrastru cture (RPKI) systems\, aimed at making Internet routing more secure and re duce the risk of BGP hijacking. These systems allow members to log into we b-based portals to request an RPKI certificate and use it to publish Rout e Origin Authorization (ROAs). In the hosted setup certificates\, and keys \, and signed products are all kept and published in the RIR infrastructur e.\n\nHowever\, four out of five RIRs also allow members to run their own RPKI infrastructure as a so-called Delegated RPKI Certificate Authority. L ACNIC as the last RIR not to provide this option yet\, is committed to hav e this functionality available by the end of 2019.\n\nWhile a hosted set-u p serves many small ISPs well\, there may be good reasons to run your own infrastructure instead. Possible use cases exist for:\n- Operators who req uire easier RPKI management that is integrated with their own systems in a more streamlined way\n- Operators who are security conscious and require that they are the only ones in possession of the private key of a system t hey use\n- Operators who want to be operationally independent from the par ent RIR\, such as National Internet Registries (NIRs) or Enterprises\n- Op erators of global networks may wish to operate a single system\, rather th an maintain ROAs in up to five web interfaces.\n\nHowever\, running your o wn CA comes at a cost. The talk will discuss these as well as possible mit igation strategies. For instance\, providing the necessary availability ca n be managed by outsourcing publication to a cloud service provider.\n\nFi nally\, the talk will look into existing and upcoming options for deployin g a CA. \n\nAt the end of the talk\, interested users will have a better u nderstanding of which choice is best for their organization.

Most of the area has no grid power. Over 900 ar tisans and 90 food vendors serve upwards of 40\,000 visitors during the Ju ly event. Providing payment card access to the nearly 1\,000 vendors has b een an ongoing challenge. The OCF IT crew has leveraged cable system techn ology to deploy a distributed wi-fi network throughout the fairgrounds. Ch allenges include powering the radio equipment\, good coverage in the folia ge\, limiting access to necessary services\, and environmental issues as t he area is a flood zone in winter. Using CMTS and coaxial cable trunk line s was the key. Wireless nodes are powered via the distribution cable. The same network is also used for operational needs\, security\, etc. LOCATION:Grand Ballroom END:VEVENT BEGIN:VEVENT SUMMARY:Comparing the network performance of AWS\, Azure and GCP DTSTART;VALUE=DATE-TIME:20190218T193000Z DTEND;VALUE=DATE-TIME:20190218T200000Z DTSTAMP;VALUE=DATE-TIME:20191029T155742Z UID:1909 CONTACT:Archana Kesavan DESCRIPTION:Speaker: Archana Kesavan\n\nAmazon Web Services\, Microsoft Az ure and Google Cloud all significantly invest in their backbone networks a nd global regional data center presence to support performance requirement s.

While the initial go al of IXPs was to bring together networks residing in the same city or cou ntry\, and thus keep local traffic local\, we observe that this model is g radually shifting. Many networks connect to IXPs without having physical p resence at their switch(es). This practice\, called Remote Peering\, is ch anging the Internet topology and economy\, and has become subject of a con tentious debate within the network operators community. However\, despite the increasing attention it is drawing\, the understanding of the characte ristics and impact of remote peering is limited. In this work\, we remove the veil between remote peering and IXPs\, by introducing and thoroughly v alidating a methodology for discovering remote peers at IXPs. We (i) infer remote peers globally\, with high accuracy (>95%)\, (ii) study the evolut ion of remote peering in time\, and (iii) evaluate its impact on Internet performance and resilience. We observe that remote peering is a significan tly common practice in all the IXPs studied\; for the largest IXPs\, remot e peers account for 40% of their member base. We also show that today IXP growth is mainly driven by remote peering\, which contributes two times mo re than local peering.

Each vendor has pledged t o roll out this change in some version of their software by the ‘Flag Da y.’ \n\nDomains served by DNS servers that are not compliant with the st andard will not function reliably after February 1\, 2019\, and may become unavailable.\n\nIf your company’s DNS zones are served by non-compliant servers\, your online presence will slowly degrade or disappear as ISPs a nd other organizations update their resolvers. When you update your own in ternal DNS resolvers to versions that don’t implement workarounds\, some sites and email servers may become unreachable.\n\nThis talk will cover t he background of the changes\, potential affects on Internet users/provide rs and testing methodologies to ensure minimal impact.\n\n*** Please note the following: We in the DNS community thought we had provided plenty of advance notice and forewarning of this flag day. We did not originally in tend to give this talk at NANOG 75 as it is post flag day. However\, we h ave received an alarming number of "OMG\, will my DNS will stop working?" inquires in the past couple of weeks. It appears auditors have just start ed running compliance checks. As such\, we feel this will now be a timely talk.

At the same time\, network configuration is hard to get right be cause of the scale and heterogeneity of modern networks\, the low-level na ture of vendor configuration languages\, and the complexity of intended po licies. The emerging field of formal network validation is a direct respon se to this challenge. Researchers have recently developed a range of techn iques to scalably and comprehensively reason about the correctness of the network configuration.\n\nI will present a network validation tool\, calle d Batfish (www.batfish.org)\, along with its new Python client library\, w hich is completely open source and has been used successfully inside many large networks. The talk will cover its software architecture\, provide a hands-on view of using it for common validation tasks\, and how the techn ology can be embed into the network’s lifecycle. The talk will include a detailed discussion of many bugs that Batfish has uncovered in real large networks.

In such an architecture\, each\n participating Autono mous System (AS) deploys multiple independent\n Autonomous System Border Routers (ASBRs) for peering\, and Equal Cost\n Multi-Path (ECMP) load b alancing is used between them. There are\n numerous benefits to this ar chitecture\, including but not limited to\n N+1 redundancy and the abili ty to flexibly increase capacity as\n needed. A cost of this architectu re is an increase in the amount of\n state in both the control and data planes. This has negative\n consequences for network convergence time a nd scale.\n\n In this session we describe how to mitigate these negative \n consequences through configuration of the routing protocols\, both BG P\n and IGP\, to utilize what we term the "Abstract Next-Hop" (ANH). Us e\n of ANH allows us to both reduce the number of BGP paths in the\n c ontrol plane and enable rapid path invalidation (hence\, network\n conve rgence and traffic restoration). We require no new protocol\n features to achieve these benefits.

So what do we do? \n\nWe believe there is enough incentive to implement the minimal\, absolutely essential elements of routing security - especially if they are perceived as a commo n business expectation\, a norm. These norms many not necessarily bring ta ngible benefits to the individual network adhering to them\, but they bene fit society and the Internet as a whole. Norms can have wide societal supp ort and help expose those who do not adhere to them\, allowing for correct ive actions.\n\nIn this talk\, we will look at the Internet routing ecosys tem and identify three main categories of actors: ISPs\, IXPs\, and cloud/ content providers. We will explore which actions can have the biggest impa ct on the security of inter-domain routing and look at some of the inciden ts from 2018 and how they could have been avoided.\n\nFinally\, we'll pres ent three minimum baselines for the respective categories and discuss how they can become norms.\n\nTo make the discussion more interactive\, it wil l include real-time polling of the audience.\n LOCATION:Grand Ballroom END:VEVENT BEGIN:VEVENT SUMMARY:RPKI: Legal Barriers and New Directions DTSTART;VALUE=DATE-TIME:20190219T193000Z DTEND;VALUE=DATE-TIME:20190219T200000Z DTSTAMP;VALUE=DATE-TIME:20191029T155742Z UID:1900 CONTACT:Christopher Yoo DESCRIPTION:Speaker: Christopher Yoo\, University of Pennsylvania\n\n2018 saw major growth in adoption of the Resource Public Key Infrastructure (RP KI) framework for routing security\, with NANOG 74 marking an inflection p oint. Over the year\, players like Cloudflare and NTT began participating in the framework\; the five Regional Internet Registries engaged in effort s to make implementing RPKI easier\; programs like the Mutually Agreed Nor ms for Routing Security promoted RPKI around the world. At NANOG 74 in par ticular\, many talks and myriad hallway discussions pushed the RPKI effort forward. As a result\, RPKI use is higher than ever before. In Europe\, f or example\, over 40% of announced IP space is now covered by a Route Orig in Authorization—the attestation establishing who is permitted to publis h routing announcements for given IP space. Yet\, while North American num bers have increased\, they remain below 10%. To ensure continued RPKI grow th\, the NANOG community must pay sustained attention to the adoption effo rt.\n\n \n\nIn addition to describing industry-wide efforts to develop awa reness and better software tools to ease RPKI implementation\, this talk w ill present the recommendations of my team’s report\, published in Decem ber 2018\, concerning the legal structure supporting RPKI’s adoption\, w hich were heavily influenced by discussions at NANOG 74. Those discussions have already resulted in important changes to how RPKI resources are dist ributed by the American Registry for Internet Numbers (ARIN). ARIN further plans to consider a set of recommendations in the spring of 2019. The tal k will outline the reasons behind the recommendations in light of communit y dialogue after NANOG 74. Further\, the talk will raise an important new possibility: Would it be valuable to establish an independent nonprofit or ganization devoted to publishing the North American RPKI repository? Such an organization would require significant effort to create and operate\, b ut it may be more reliable and resilient when compared with the current st ructure for RPKI repository distribution.

With recent advances in router/switch archite ctures\, embedded control plane protocols and central application software a single MPLS network layer can deliver any service that so far only PDH\ , SONET or OTN could deliver. During this session we will talk about some common "concerns" such as cost of transmission\, latency & jitter\, bandwi dth guarantees & loss\, service assurance & OAM and how they are no longer valid for a "neatly designed" MPLS transport network allowing network ope rators to remove the complexity of running many parallel networks. \n\nSub mitted for Christian Schmutzer\, Principal Engineer\, Optical Systems\, Ci sco \nBio: Christian Schmutzer is a Principal Engineer at Cisco Systems an d has been with the company since 1998.

Attendees will learn how to expr ess conventional and novel data-plane applications in the P4 language\, an d how to compile\, execute\, and evaluate P4 programs. We will provide a V M image containing all the necessary packages and tools. The P4 specificat ion is publicly available at the P4 website under an Apache license. Key d evelopment tools are available as open-source tools (http://github.com/p4l ang).\n\nP4 (www.p4.org) is a programming language for describing how netw ork packets should be processed on a variety of targets\, ranging from gen eral-purpose CPUs to network processors\, FPGAs\, and custom ASICs. P4 was designed with three goals in mind: (i) protocol independence: devices sho uld not “bake in” specific protocols\; (ii) field re-configurability: programmers should be able to modify the behavior of devices after they ha ve been deployed\; and (iii) portability: programs should not be tied to s pecific hardware targets. The P4 community maintains the language specific ations\, a set of open-source development tools\, and sample P4 programs w ith the goal of making it easy for P4 users to quickly and correctly autho r new data-plane behaviors. \n\nP4 continues to be a transformative techno logy in networking and an increasingly popular choice for developing data- plane designs. Well-known data-plane features typically realized in a fixe d-function logic are now being authored in P4\, allowing network owners to understand and even verify their network devices’ behavior in an unambi guous manner. Meanwhile\, new ideas are also being prototyped\, evaluated\ , and productized in P4. We believe there are many opportunities for netwo rk operators to help evolve the design of the language\, discover new impl ementation techniques\, and develop their own custom use cases.

The three-tiered Core\, Aggregation/Distribution\, and Access model is familiar to every network engineer. Server virtualizat ion and new application frameworks have forced us to reconsider this model . Instead of a multi-tier hierarchical design\, we have found folded-Clos (spine-leaf) networks much more efficient at moving large quantities of pa ckets from anywhere to anywhere. In order to keep up with the speed of vir tualized compute and storage\, we’ve adopted virtualized networks that r un as an overlay (with the physical Clos network becoming an underlay). \n \nVisualizing the network in this way gives us a new 2-tier model. Instead of trying to conceptualize the physical network into an outdated hierarch y\, we can now look at the entire logical network platform as a two tier s ystem. The (spine-leaf) underlay is the Core layer switch and the overlay is the Access layer router. This is super helpful when we want to decide w here network functions should live. The Core is still there to move packet s\, fast\, and the Access is there to handle routing and policy as well as to provide additional features and functions.

In the IEEE 8 02 Standards Committee\, the IEEE 802 "Network Enhancements for the Next D ecade" Industry Connections Activity (Nendica)\, which identifies industry requirements and trends\, has published its first report\, covering lossl ess networks for data centers. This report documents trends to reduce and eliminate congestion that leads to packet loss and unacceptable latency in the modern data center. As a result of that study\, IEEE 802 has already begun standardization on one solution\, based on congestion isolation as a n improvement to priority flow control. Nendica continues to seek user par tnerships to help steer future standardization in a productive direction. In November 2018\, Nendica cooperated with IETF on the 802/IETF Data Cente r Workshop\, identifying many areas of potential cooperation and complemen tary opportunities. This NANOG presentation reviews some of the technologi es described in the IEEE 802 Nendica Report "The Lossless Network for Data Centers." It also proposes opportunities for cooperation with communities such as NANOG with an interest in networks and data centers.

Such as by computing:\nPaths considering a subset of the routers in your n etwork? – a network plane or slice\nPaths that minimize cumulative delay to a destination based on measured per-link delay?\nPaths traversing only encrypted MACsec links? Both for primary and pre-computed backup paths\nP aths traversing only high speed interfaces\n\nAll the above use cases are now possible. And furthermore\, they are possible at scale and based on t he source routing paradigm. Meet SR Flexible Algorithms !!!\nSR Flexible A lgorithms (FA) is the latest standards-based tool in the SR TE toolkit. FA allows operators to tailor IGP SPF computation according to their own nee ds. An operator can define and assign new SR segments (prefix SIDs) to rea lize forwarding beyond SPF based on link cost. As a result\, FA provides a traffic engineered path from anywhere to anywhere automatically computed by the IGP.\n\nThis presentation provides a technical overview of this new technology and its benefits for network operators\, including:\nFlexibili ty –operator defines algo\nSimplicity –single IGP process\, and single loopback with multiple SIDs\nScalability –single SID (instead of a labe l stack) can now be used to enforce traffic on the Flex-algo specific path \nRich functionality –optimum sub-50msec TI-LFA backup paths respecting the same optimization objective and constraints as the primary path\nAutom ation –FA inherits all the scale and automation benefits powered by inte nt-based networking with on-demand SR policy instantiation and automated t raffic steering\n\nMore importantly\, presentation dwells into key use cas es that leverage this solution\; including:\nMulti-plane network designs\n Intent-based network slicing\nLow latency routing\nSecured Intelligent Tra nsport\n\nWhy is this session relevant to NANOG?\nFA is a new concept with large set of use cases. Thus\, we consider that this topic will be of int erest for the NANOG audience.
