Speaker
Najam Ahmad, Facebook
Abstract Recently there was a blog post on Linkedin talking about the skills required to be a successful network engineer in the future. While the skills listed were all relevant and made sense, there was a key element missing – an operational mindset. To be successful at building and managing large scale infrastructure there has to be an operations first mindset to developing technology. It’s not simply about “automating” things or having a dev-ops team. This talk uses Facebook’s disaster recovery efforts as a case study to describe this mindset and approaches to deploying infrastructure that survives disasters without significant human intervention.

T-Mobile's journey to IPv6 Only networking
Date/Time 1:30 PM to 2:00 PM recorded
Location Centennial Ballroom

Speaker
Stephan Lagerholm
Stephan Lagerholm - Senior Manager, Systems Design & Strategy, Technology Stephan Lagerholm is an experienced networking thought leader who designs, builds and operates large and complex networks. He has experience in a wide array of network technologies with a deep expertise in DNS. Stephan is currently employed at T-Mobile where he leads a team of network, OpenStack and DNS architects. Previously, he managed the team responsible for DNS at Microsoft, as well as held senior leadership positions at Secure64 Software Corporation. In 2008 Stephan co-founded the Texas IPv6 Task Force with Stan Barber, and he served on the board until 2014. Stephan holds a Master of Computer Science degree from Uppsala University, Sweden.
Abstract Over the last 10 years, T-Mobile have had a strategy of removing our dependency of IPv4. In the spring of 2017 we finally flipped the switch and turned off IPv4 for over 10 million handsets. As of March 2018 we only have a single digit % of our users relying on IPv4. We have in other words reached the utopia of making our customer experience independent of IP transport protocol. To achieve this we are using DNS64 and related technologies. Stephan will share some of T-Mobile’s experience with DNS64 and give some advice on how to find and handle broken applications and websites. Talk outline: • Background T-Mobile’s journey towards IPv6 only • Background, RFC6147, RFC6877 and RFC7050 • Selection algorithm and happy eyeballs (RFC6555, RFC8305) • Common failure scenarios for IPv6 only hosts • RFC compliance and how popular DNS64 resolvers react to various common DNS misconfigurations • Conclusion and learnings

Michael Schapira
Abstract The Network Time Protocol (NTP) synchronizes time across computer systems over the Internet. Unfortunately, NTP is highly vulnerable to “time shifting attacks”, in which the attacker’s goal is to shift forward/backward the local time at an NTP client. NTP’s security vulnerabilities have severe implications for time-sensitive applications and for security mechanisms, including TLS certificates, DNS and DNSSEC, RPKI, Kerberos, BitCoin, and beyond. While technically NTP supports cryptographic authentication, it is very rarely used in practice and, worse yet, timeshifting attacks on NTP are possible even if all NTP communications are encrypted and authenticated. We present Chronos, a new NTP client that achieves good synchronization even in the presence of powerful attackers who are in direct control of a large number of NTP servers. Importantly, Chronos is backwards compatible with legacy NTP and involves no changes whatsoever to NTP servers. Chronos leverages ideas from distributed computing literature on clock synchronization in the presence of adversarial (Byzantine) behavior. A Chronos client iteratively “crowdsources” time queries across multiple NTP servers and applies a provably secure algorithm for eliminating “suspicious” responses and averaging over the remaining responses. Chronos is carefully engineered to minimize communication overhead so as to avoid overloading NTP servers. We evaluate Chronos’ security and network efficiency guarantees via a combination of theoretical analyses and experiments with a prototype implementation. Our results indicate that to succeed in shifting time at a Chronos client by over 100ms from the UTC, even a powerful man-in-the-middle attacker requires over 20 years of effort in expectation.

Speaker
Artyom Gavrichenkov, Qrator Labs CZ
CTO at Qrator Labs, a DDoS mitigation and network monitoring company. Graduated from Moscow State University, faculty of Computational Mathematics and Cybernetics; has been working in the area of IT networking and monitoring for a decade. Has previously been presenting at numerous conferences, including BlackHat USA, RIPE Meeting, APNIC/APRICOT, and ICANN EE DNS Forum.
Abstract In November 2017, researchers have found a new class of amplification DDoS attacks: the memcached amplification. Soon after the discovery, at the beginning of March 2018 those attacks were already in the wild, with a bandwidth close to 1,7 Gbps. What we're going to discuss is an analysis of the threat structure, causes and consequences, and what we're able to do to prevent such issues from happening next time.

His first exposure to computer networking was a 1200 baud modem on a Commodore 64 which he still owns.
Rob Shakir, Google
Rob works in Google’s Network Architecture team where he focuses on the software surrounding the network - particularly, defining interfaces to network devices suitable for the needs of modern network operations, and evolving on/off-box control planes. Prior to Google, Rob contributed to the engineering and architecture teams running a number of global networks, including BT’s private and Internet backbones, Cable&Wireless’ L2/L3VPN network, and running an SRE team for a unified communications provider. Rob contributes to open source projects and standards bodies - co-leading the OpenConfig project, and co-chairing the SPRING (segment routing) working group in the IETF.
Abstract Modern networks have significantly outpaced the monitoring capabilities of SNMP and command-line scraping.  Over the last three years we at Google have been working with members of the networking industry via the OpenConfig.net effort to redefine network monitoring.  We have now deployed Streaming Telemetry in production to monitor devices from multiple vendors. We will talk about the experience and highlight the open source components we are providing to the community to accelerate industry-wide adoption.

Speaker
steve ulrich, Juniper Networks
steve ulrich is a networking dork in the cloud service provider group at juniper networks where for the past 4 years he has spent his days (and nights) working with customers to deploy new (and sometimes not so new) networking technologies and platforms. prior to juniper he spent 13 years as yet another networking dork for cisco systems working in the web services and service provider groups doing many of the same things.
Abstract Over the past few years, Segment Routing has received a considerable amount of attention for enabling a range of novel new network capabilities. While Segment Routing holds considerable promise in terms of network simplification and enabling new modes of operation there are a number of architectural and deployment considerations which have received little attention in the excitement to discuss what can be. This presentation is a brief discussion of some of the practical considerations in enabling Segment Routing in production networks and some of the challenges to be addressed and potential solutions. Topics include RSVP-SR coexistence and migration, label space/stack management, new traffic engineering and diagnostic considerations.
