“RANCID on speed – Salvation for Network Operators” – Marcus Stögbauer (

RANCID is used in many places to save the configuration of various network devices. A lot of people also like to use the login scripts to log into their devices without typing a password every time. But once you have the configuration stored on your hard disk there is a lot more you can do with it.

In this talk I will present a variety of scripts and tools which we wrote over the course of time that make use of the saved configuration files or RANCID tools to ease the life of network operators.

“IPTV and Multicast Surveillance” – Jesper Brouer (ComX)

The main focus is what happens when handing large amounts of multicast traffic. Or rephrased as a question; What happens to a bandwidth hungry realtime service on a loaded Ethernet switch based network?

The need for scalability, has resulted in a highly efficient iptables module “mp2t” that can handles 600Mbit/s multicast streams with a 2% CPU load and parallel processing on all cores.

The talk is NOT about the challenges to configure multicast routing at large Danish ISP in a multi vendor setup, even-though this is nontrivial.

“Locator/ID Separation Protocol (LISP)” – Jesper Skriver (Cisco)

LISP is a network architecture and set of protocols that utilizes a level of indirection to separate an IP address into two namespaces: Endpoint Identifiers (EIDs), which are assigned to end-hosts, and Routing Locators (RLOCs), which are assigned to devices (primarily routers) that make up the global routing system. In addition to helping solve routing scalability issues, LISP provides many other benefits, including: simplified and cost-effective multi-homing, including ingress traffic engineering; IPv6 transition simplification, including incremental deployment of IPv6 using existing IPv4 infrastructure (or IPv4 over IPv6); and Operation and network simplification.

“RIPE Atlas” – Robert Kisteleki, RIPE NCC

RIPE Atlas is a new active measurement network launched by the RIPE NCC in November 2010. It’s goal is to scale up to thousands, potentially tens of thousands of vantage points and execute built-in and user specified measurements. In this talk we will outline the idea, technical background, current status and plans for this initiative.

“Internet Protocol version 6” – Henrik Møll (Conscia)

This Presentation will cover some of the challenges with IPv4 exhaustion in Broadband networks. Tunneling and translation techniques and some of the issues in the access-layer in regards of Residential IPv6 deployment will be discussed.

“I-root, DNSNODE and the State of DNSSEC Software Support” – Johan Ihrén (Netnod)

Abstract coming soon

“MPLS-TE” – Julian Lucek (Juniper Networks)

We will review mechanisms and applications of MPLS-TE for unicast traffic, including Diff-Serv Aware Traffic Engineering. We will also discuss MPLS-TE for multicast traffic, using Point-to-Multipoint LSPs. Such multicast traffic engineering can be used to construct multicast trees best suited to the application, for example minimum-cost trees for situations where bandwidth efficiency is paramount, and shortest path trees for situations where minimum latency is paramount. We will also discuss how Traffic Engineering is useful for guaranteeing path diversity for Live-Live traffic delivery, which is particularly useful for Broadcast TV and Real-Time Market Data applications.
