And an entry in PeeringDB is a must have if you want to interconnect with other networks. There is no other DB where you have all the information about networks, Internet Exchange Points and Facilities/Colocation at one place and nicely interlinked.\n\nAs PeeringDB is so important an Seattle (US) based association was set up in late 2015. In March 2016 a wholly new version of PeeringDB (PeeringDB 2.0) was released with an intuitive GUI and a powerful API.\n\nThis presentation gives a quick overview on PeeringDB, both from organisation as well as from a technical point of view and highlights the latest developments.\n\nThis is a draft presentation and will be updated with latest before the meeting.\n\nPeeringDB is ongoing work and driven by the community. Although there was a presentation on PeeringDB at last DENOG meeting, it absolutely makes sense to let the audience know about latest developments.","original_language":"eng","persons":["Arnold Nipper"],"tags":["denog10","14"],"view_count":107,"promoted":false,"date":"2018-11-21T00:00:00.000+01:00","release_date":"2018-11-21T01:00:00.000+01:00","updated_at":"2026-03-11T13:30:09.718+01:00","length":581,"duration":581,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog10/14-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog10/14-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog10/b327ff44-652e-5810-9d9f-1c950412d450-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog10/b327ff44-652e-5810-9d9f-1c950412d450-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog10-14-peeringdb-update","url":"https://api.media.ccc.de/public/events/b327ff44-652e-5810-9d9f-1c950412d450","conference_title":"DENOG 10","conference_url":"https://api.media.ccc.de/public/conferences/denog10","related":[{"event_id":6331,"event_guid":"5d933306-725a-5f63-be49-1a763b722af2","weight":4},{"event_id":6336,"event_guid":"535ef03a-4e9c-5364-8a9c-60cd995b7067","weight":13},{"event_id":6337,"event_guid":"c8f76b25-20e6-5083-9cc0-ca99eec81eb6","weight":17},{"event_id":6339,"event_guid":"e323a8be-0bc6-553f-b54b-2ffc0b226c12","weight":11},{"event_id":6340,"event_guid":"95aab8ea-e8ec-539f-9e96-b31da306f682","weight":17},{"event_id":6342,"event_guid":"8340fbc9-2735-5560-b3f4-ac36f8f5a35d","weight":23},{"event_id":6350,"event_guid":"6053cc14-64d3-556e-93e0-543a5458cb29","weight":13}]},{"guid":"6053cc14-64d3-556e-93e0-543a5458cb29","title":"A short update on SSH security","subtitle":null,"slug":"denog10-27-a-short-update-on-ssh-security","link":"https://cfp.denog.de/denog10/talk/EYFVZY","description":"Everybody uses it, the most of them love it.

An overlay network allows (live) migration of VMs and multi-tenancy in infrastructure. Unfortunately, with typical setups, the physical underlay network infrastructure is ignored. This deployment scenario has multiple downsides:\n\n- Current overlay implementations in Openstack are not based on standardized protocols. If integration with the underlay network is necessary, the network vendor has to develop support to integrate with the Openstack overlay (e.g OVSDB, OVN, ML2).\n- For example, It can cause inefficient traffic routing through a network node, adding additional latency and a point of failure.\n\nWith EVPN-VxLAN (RFC8365 with multiple additions), integration with the physical network is much easier given the use of a standardized protocol. Also, the additions of the distributed routing functionality in EVPN allows for the possibility to have a distributed routing setup in Openstack that prevents traffic tromboning.\n\nEVPN VxLAN is implemented in the FreeRangeRouting project. In combination with the Linux VRF implementation. An Openstack hypervisor can become a VxLAN VTEP and have the EVPN functionalities directly available on the host.","original_language":"eng","persons":["Attilla de Groot"],"tags":["denog10","40"],"view_count":298,"promoted":false,"date":"2018-11-22T00:00:00.000+01:00","release_date":"2018-11-22T01:00:00.000+01:00","updated_at":"2026-04-03T17:00:04.853+02:00","length":1925,"duration":1925,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog10/40-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog10/40-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog10/7c795e89-1cb5-500e-9299-c2896391959f-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog10/7c795e89-1cb5-500e-9299-c2896391959f-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog10-40-evpn-to-the-host","url":"https://api.media.ccc.de/public/events/7c795e89-1cb5-500e-9299-c2896391959f","conference_title":"DENOG 10","conference_url":"https://api.media.ccc.de/public/conferences/denog10","related":[{"event_id":6336,"event_guid":"535ef03a-4e9c-5364-8a9c-60cd995b7067","weight":8},{"event_id":6337,"event_guid":"c8f76b25-20e6-5083-9cc0-ca99eec81eb6","weight":14},{"event_id":6340,"event_guid":"95aab8ea-e8ec-539f-9e96-b31da306f682","weight":12},{"event_id":6343,"event_guid":"b05a50fb-0f40-52a1-8f39-ebbca73564c2","weight":17},{"event_id":6347,"event_guid":"36f3330d-6ed9-5f33-9a32-a2897c1c7631","weight":3},{"event_id":6350,"event_guid":"6053cc14-64d3-556e-93e0-543a5458cb29","weight":12},{"event_id":6351,"event_guid":"f3c974f2-52c2-54e1-a69a-069c4ffec695","weight":14},{"event_id":6353,"event_guid":"d6500362-96db-5451-a0db-769560a1624b","weight":3}]},{"guid":"627f23ef-8a06-5f84-acef-a3065a315957","title":"BIO routing - a versatile, fast and reliable open source routing daemon in golang","subtitle":null,"slug":"denog10-25-bio-routing-a-versatile-fast-and-reliable-open-source-routing-daemon-in-golang","link":"https://cfp.denog.de/denog10/talk/TPNXPX","description":"BIO routing is a project to create a versatile, fast and reliable routing daemon in Golang (BIO = BGP + IS-IS + OSPF).

In this talk Werner will give an insight into the features and architecture of this firewall, which is being developed with a strong focus on security and code quality.\n\nOPNsense has started in January 2015 as a fork of pfSense® and m0n0wall. Now - almost four years later - OPNsense brings the rich feature set of commercial offerings with the benefits of open and verifiable sources. It's feature list ranges from basic features like the Stateful Firewall and Caching Proxy, over Unified Thread Management functions (Suricata-based IDS/IPS, Virus Protection, VPN, ...) up to enterprise features like High Availability clustering or an API for automation purposes. A modern and intuitive web interface makes configuring firewall rules also for beginners funny.\n\nIn this talk, Werner Fischer will outline OPNsense's FreeBSD/HardenedBSD-based architecture and how you can take advantage of additional features using OPNsense plugins. He will also show how to initially setup an OPNsense firewall, and how you use datacenter-features like High Availability \u0026 Hardware Failover or Dual Uplinks.\n\nOpen (source) makes sense - also for your firewall :-)","original_language":"eng","persons":["Werner Fischer"],"tags":["denog10","22"],"view_count":1165,"promoted":false,"date":"2018-11-21T00:00:00.000+01:00","release_date":"2018-11-21T01:00:00.000+01:00","updated_at":"2026-04-05T16:30:04.643+02:00","length":628,"duration":628,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog10/22-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog10/22-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog10/e323a8be-0bc6-553f-b54b-2ffc0b226c12-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog10/e323a8be-0bc6-553f-b54b-2ffc0b226c12-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog10-22-opnsense-the-open-firewall-for-your-datacenter","url":"https://api.media.ccc.de/public/events/e323a8be-0bc6-553f-b54b-2ffc0b226c12","conference_title":"DENOG 10","conference_url":"https://api.media.ccc.de/public/conferences/denog10","related":[{"event_id":5792,"event_guid":"f5c68cea-eb34-49ae-bb15-d0fc1085985b","weight":22},{"event_id":6331,"event_guid":"5d933306-725a-5f63-be49-1a763b722af2","weight":15},{"event_id":6333,"event_guid":"c7ce944c-dedc-55b0-b5fa-8f3ca1236695","weight":16},{"event_id":6334,"event_guid":"b69e946a-8b47-5e04-ab20-e761f1ce9450","weight":25},{"event_id":6335,"event_guid":"627f23ef-8a06-5f84-acef-a3065a315957","weight":14},{"event_id":6336,"event_guid":"535ef03a-4e9c-5364-8a9c-60cd995b7067","weight":46},{"event_id":6337,"event_guid":"c8f76b25-20e6-5083-9cc0-ca99eec81eb6","weight":39},{"event_id":6338,"event_guid":"34449bcc-efc3-5c53-8723-887ae2c632a8","weight":18},{"event_id":6340,"event_guid":"95aab8ea-e8ec-539f-9e96-b31da306f682","weight":37},{"event_id":6342,"event_guid":"8340fbc9-2735-5560-b3f4-ac36f8f5a35d","weight":47},{"event_id":6343,"event_guid":"b05a50fb-0f40-52a1-8f39-ebbca73564c2","weight":22},{"event_id":6348,"event_guid":"68bfa511-4aab-510b-a631-aa515976841e","weight":16},{"event_id":6350,"event_guid":"6053cc14-64d3-556e-93e0-543a5458cb29","weight":53},{"event_id":6351,"event_guid":"f3c974f2-52c2-54e1-a69a-069c4ffec695","weight":28},{"event_id":6353,"event_guid":"d6500362-96db-5451-a0db-769560a1624b","weight":18}]},{"guid":"34449bcc-efc3-5c53-8723-887ae2c632a8","title":"ND Spoofing for Fun and Profit: Distributing server farm traffic efficiently","subtitle":null,"slug":"denog10-19-nd-spoofing-for-fun-and-profit-distributing-server-farm-traffic-efficiently","link":"https://cfp.denog.de/denog10/talk/ZML88Q","description":"A server farm in a single broadcast domain should use a shortest way to the next router minimizing inter-switch traffic.

Several competing data models for disaggregated and partially disaggregated optical networks currently being developed and proposed by research and standardization are presented and their strengths and challenges discussed.\n\nA key use case of SDN for optical transport networks (Transport SDN) is multi-vendor network and service management. The requirement for interoperability drives open and standardized interfaces. This talk will introduce the data models currently being discussed as contenders for application programming interfaces (APIs) of disaggregated and partially disaggregated optical networks on device and network level.  \nIn case of fully disaggregated networks, each device is directly controlled by an SDN controller; in case of partial disaggregation, an optical line system (OLS) is operated as a complete system, and the transponders at the edge are operated independently from the OLS and can be directly controlled.  \nThe strengths and weaknesses of the two disaggregation models and the considered APIs, including OpenConfig, OpenROADM, IETF TEAS, and ONF Transport API, are discussed in the talk.  Current results from ongoing interop events, field trials, and research projects are presented to highlight challenges and solutions for the SDN control of (partially) disaggregated optical networks.","original_language":"eng","persons":["Achim Autenrieth"],"tags":["denog10","38"],"view_count":172,"promoted":false,"date":"2018-11-22T00:00:00.000+01:00","release_date":"2018-11-22T01:00:00.000+01:00","updated_at":"2026-03-01T20:45:11.094+01:00","length":1710,"duration":1710,"thumb_url":"https://static.media.ccc.de/media/events/denog/denog10/38-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/denog/denog10/38-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/denog/denog10/2a6a17cc-cd0b-5611-8a92-deefe870677f-timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/denog/denog10/2a6a17cc-cd0b-5611-8a92-deefe870677f-thumbnails.vtt","frontend_link":"https://media.ccc.de/v/denog10-38-sdn-control-of-disaggregated-optical-transport-networks","url":"https://api.media.ccc.de/public/events/2a6a17cc-cd0b-5611-8a92-deefe870677f","conference_title":"DENOG 10","conference_url":"https://api.media.ccc.de/public/conferences/denog10","related":[{"event_id":6333,"event_guid":"c7ce944c-dedc-55b0-b5fa-8f3ca1236695","weight":4},{"event_id":6336,"event_guid":"535ef03a-4e9c-5364-8a9c-60cd995b7067","weight":2},{"event_id":6339,"event_guid":"e323a8be-0bc6-553f-b54b-2ffc0b226c12","weight":2},{"event_id":6341,"event_guid":"b327ff44-652e-5810-9d9f-1c950412d450","weight":2},{"event_id":6342,"event_guid":"8340fbc9-2735-5560-b3f4-ac36f8f5a35d","weight":2},{"event_id":6343,"event_guid":"b05a50fb-0f40-52a1-8f39-ebbca73564c2","weight":4},{"event_id":6346,"event_guid":"7c795e89-1cb5-500e-9299-c2896391959f","weight":4},{"event_id":6347,"event_guid":"36f3330d-6ed9-5f33-9a32-a2897c1c7631","weight":2},{"event_id":6349,"event_guid":"9b14c4bd-ae07-514c-9145-3db405b27a89","weight":4},{"event_id":6350,"event_guid":"6053cc14-64d3-556e-93e0-543a5458cb29","weight":4},{"event_id":6351,"event_guid":"f3c974f2-52c2-54e1-a69a-069c4ffec695","weight":4},{"event_id":6353,"event_guid":"d6500362-96db-5451-a0db-769560a1624b","weight":2}]},{"guid":"c8f76b25-20e6-5083-9cc0-ca99eec81eb6","title":"How to operate a VXLAN network","subtitle":null,"slug":"denog10-18-how-to-operate-a-vxlan-network","link":"https://cfp.denog.de/denog10/talk/LGPWXJ","description":"I operate a VXLAN based network spread across multiple data centers which provides IP- and Ethernet-services for our customers.
