RIPE 71 attendees were welcomed to Bucharest with unseasonably warm weather, a nice change for a November meeting.

Day 1 began with parallel tutorials: NetDevOps – Ansible 101 to Network Nirvana, Introduction to RIPE Meetings and RIPE Database Tips and Tricks. The Newcomers Introduction session gave first-time attendees some insight into “RIPE Meeting 101” with help from RIPE NCC Managing Director Axel Pawlik and RIPE Chair Hans Petter Holen.

The meeting began after lunch (if you were still hungry after all the food in the coffee break!) with an afternoon of plenary presentations.

Opening Plenary highlights included:

• The ins and outs of mobile satellite Internet, including maritime connectivity services and the finer points of geolocation
• A lively presentation on automatic certification issuance that instigated a discussion on DANE’s role in security
• Lightning talks about the Internet outage in Amsterdam during RIPE 70 and BGP security at IXPs

The last plenary session of the day focused on DDoS attacks. Highlights included:

• How to capture them for later analysis
• How to detect and combat them using FastNetMon
• FastNetMon use cases

The session concluded with a lightning talk on connecting 100Gbit/s links, what’s possible and what’s not.

The first socials of the meeting week took place in the hotel. Attendees mingled with the RIPE NCC Executive Board and then celebrated the end of a great meeting day at the Welcome Drinks.

Another beautiful day in Bucharest and another great line-up of engaging plenary presentations at RIPE 71.

Tuesday morning’s 9:00 plenary focused on network measurements, and two-thirds of the presenters were from past and present RIPE Academic Cooperation Initiative (RACI) attendees:

• RACI attendee Dario Rossi, Telecom ParisTech, presented results about where in the world anycast networks can be found
• Andra Lutu (RACI alumni) from Simula Research Laboratory explained MONROE, a mobile broadband measurement platform
• Jamie Horrell, NZRS, talked about research into spatial representation, including lots of pretty maps of New Zealand’s broadband infrastructure

Attendees queued up for their RIPE 71 meeting t-shirts during the coffee break before filling up the main room for the second plenary session.

Highlights included:

• A look at the tools used to maintain the Facebook network, use cases, the lessons learned and resulting recommendations from Facebook’s Jose Leitao and David Rothera
• The design of a small data centre, the mistakes made and problems that present themselves from Karl Brumund, Dyn
• Leslie Carr on the pros of automation, the importance of network and system teams working together and how amazing Git and GitHub is

The afternoon’s first plenary slot on Tuesday had a broader, less technical focus that prompted a lot of audience comments. Highlights included:

• A presentation from University of Leiden students (and RACI attendees) on international humanitarian law and cyber warfare
• An in-depth update from the RIPE Crisp Team on the IANA Stewardship Transition

Highlights of the last session of the day included:

• Pitches from RIPE Programme Committee candidates
• APNIC’s George Michaelson on how adverts can be used to measure IPv6 deployment
• RACI attendee Yves Vanauble delving into MPLS
• Lightning talks from RIPE NCC staff on BGPlay and multi-CDNs resemblance to jellyfish

The day finished with presentations from talented students and researchers in the RACI session (see: ripe.net/ripe/raci) and a parallel BoF on addressing the problem of IP spoofing.

Attendees then boarded the shuttle busses and headed to Maraboo for a fun night of networking, dancing and great food (thank you to RIPE 71 host Interlan!).

Despite many confessions of post-party sleepiness, Wednesday kicked off in full force with the working group sessions. Here are the day’s highlights:

Address Policy Working Group – Sessions I and II

• Nick Hilliard presented on the (now withdrawn) proposal to remove the multi-homing requirement to receive an AS Number and the working group agreed on an approach for a new draft proposal as well as a formal statement to the IETF that more work is needed to resolve outstanding issues with 32-bit ASNs
• The working group discussed Erik Bais’s proposal to unify all of the transfer policies into one new transfer policy document
• There was further discussion of Radu-Adrian Feurdean’s and Elvis Velea’s proposal to allow LIRs additional allocations from the last /8; with no more agreement emerging during the session than on the mailing list, it was decided that the WG will likely not reach consensus with the wording as it currently stands and Radu-Adrian said he would work on one more version of the proposal with the WG’s feedback
• Ciprian Nica outlined the historical reasons behind Romania becoming the top exporter of IPv4 addresses via the transfer market
• Ingrid Wijte gave a report from RIPE NCC Registration Services and highlighted the increase in some LIRs asking End Users to pay increased fees to continue using their resources or to purchase them outright; however, it was agreed that there was little the WG or the RIPE NCC could do in these cases

Connect Working Group

• The working group agreed to conclude work on the “Working With CDNs” BCOP
• Emile Aben presented his research on the paths that traffic takes and whether it stays in or goes out of country, highlighting some interesting examples in Romania, Sweden, France, Argentina and Chile
• Martin Levy presented a short overview of one of the tools created during the RIPE Atlas hackathon that took place before RIPE 71 called ASN Tryst, an ASN to ASN interconnect viewer
• Thomas King presented more details on traffic volume dependencies between IXPs

MAT Working Group

• Dario Rossi explained how he’s measuring the effect of carrier-grade NAT on web traffic and performance
• Brian Trammel shed some light on Internet path transparency and showed that 0.5% of the Alexa top one million sites refuse to connect with ECN (Explicit Congestion Notification), although this is saved by fallback
• Vesna Manojlovic asked for feedback about how the RIPE Atlas team should implement WiFi measurements; there’s a poll available on RIPE Labs that she invited everyone to take
• Sascha Bleidner, the winner of the RIPE Atlas hackathon that took place the weekend before RIPE 71, presented his team’s winning traceroute tool for comparing your own path and latency to your (geographical) neighbour’s

IPv6 Working Group

• Benedikt Stockebrand gave an in-depth look at IPv6 from the enterprise perspective, outlining common problems that go beyond the purely technical aspects
• The session included a number of practical lightning talks about vulnerability detection, deployment tooling and BCOPs
• There was an open mic discussion on how to move forward with the IPv6-only network during RIPE Meetings; making sure the service is stable and supported were considered the most important goals

RIPE NCC Services Working Group

• Axel Pawlik gave an update on the RIPE NCC’s actions and outlook, noting some focal points for 2016 that include maintaining a strong registry, enhancing RIR accountability ahead of the IANA stewardship transition, expanding outreach throughout the RIPE NCC service region, and providing enhanced statistics and analysis
• Alex Band explained how several services have been streamlined, including the membership sign-up process, resource requests, the RIPE Database interface, and registry changes
• A proposal for a capital endowment fund to support the IETF generated a lively discussion

With no pre-planned social on Wednesday night, attendees headed out into the Bucharest night in search of sarmale, pălinca and a good time with friends and colleagues.
