How to Successfully Peer at 20+ Internet Exchanges How to successfully peer at 20+ Internet exchanges Grzegorz Janoszka Network Design Engineer LeaseWeb B.V. Contents . Introduction . History of peering connections of LeaseWeb – from 0 to 30 . Why to peer? Why at so many exchanges? . Detailed analysis of AMS-IX, DE-CIX, LINX and PLIX . Tips and hints for cost effective peering . Is the sky really the limit? . Summary, Q&A LeaseWeb, established in 1997, is now one of the biggest hosting companies with multiple datacenters in EU and US. 70.000.000 € revenue . 40.000 servers . >10.000 customers . 1.250.000.000.000 bps traffic . 200 employees OCOM group: LeaseWeb – hosting EvoSwitch – running datacenters FiberRing – ISP, data transmission DataXenter – building modular datacenters Brief history of peering connections: . 1997 - Company founded, first servers in datacenters within Amsterdam area . 2000 - Own IP’s and ASn (16265) assigned . 2002 - AMS-IX (existing since 1994) matures and starts a professional NOC, Leaseweb joins with 1GE port . 2005 – first DE-CIX connection, also 1GE . 2007 – first LINX connection, 10GE . 2008 – 10GE: BNIX , Netnod; 1GE: PLIX, SwissIX, NYIIX, VIX, NIX.CZ . 2009 – 1GE: Espanix, SIX, MIX, BIX, Interlan . 2010 – 1GE: DIX, NIX, FranceIX, LU-CIX, FreeBIX, NL-IX . 2011 – Equinix Ashburn . 2011-2012 – ECIX, Equnix: Palo Alto, Dallas, Chicago, New York, Los Angeles, Telex, NOTA, Any2 Los Angeles, Lonap... Current capacity to Internet Exchanges: . AMS-IX – 140 Gbps . DE-CIX – 70 Gbps . LINX – 50 Gbps . 20 Gbps: Netnod, Espanix, NL-IX . 10 Gbps: SwissIX, BNIX, PLIX, FranceIX, BIX, MIX, Equinix Ashburn . 1 Gpbs: 9 others . 22 connected, 10 more to go Why to peer (publicly)? It is NOT another peering vs transit debate... ...but peering is just cheaper... at least for us Typical 10GE wave cost is about 3000€ MRC, plus ~2000€ IX fee gives ~0.5 €/Mbps With transits for ~1€/Mbps it may be cheaper, efficiency is the key. Other peering advantages: . Marketing value – our customers like it and it is very important for some of them . Better performance, increased redundancy and resiliency . Public peering can be just a prelude and a reason of a private peering later on . Provides a relatioship with a peer, it is easier to request assistance and troubleshoot problems together Almost a dozen Internet exchanges with only 1 Gbps connection while generating 1.25 Tbps total traffic... does it make any sense? . it is not always much cheaper... ...but it is important for our customers . you can learn the market, already get peers, estimate traffic and then you can upgrade to 10GE, which provides cheap traffic . almost no administrative burden because of route-servers actively used With peering connections utilized less than 50% you are not going to make any money. Efficiency of utilizing links at at least 70% of capacity is the key. Steer your traffic. Don’t upgrade too fast, first build your traffic. Multiple exchanges help greately improve efficiency. With AMS-IX, DE-CIX and LINX being full you don’t have to upgrade capacity to all of them. Instead, upgrade only one, shift some traffic towards it, thus making free space on the others. Repeat the cycle upgrading only one IX at a time. Important: be a good peer, please always contact your peers before shifting your traffic. How to make your peering cheaper? . Cooperate, swap services, share costs . If your traffic is not balanced, find someone to utilize the other direction . Negotiate with exchanges, especially the smaller ones may do a lot to have you there . Be selective, use route-servers . Consider ordering multiple services with one common commitment (next slide) What are the limits? . The number of exchanges is limited, about 100 now . Only 82 ASn’s peer at 10 or more IXP’s . Only 6 ASn’s peer at 30+ IXP’s . The leader is Google peering at 54 IXP’s Google 15169 54 Akamai 20940 50 Packet Clearing House 3856 45 Limelight 22822 41 Hurricane Electric 6939 40 Woodynet DNS Anycast 42 34 Yahoo! 10310 29 E4A 34695 28 Microsoft 8075 27 RETN 9002 24 BroadbandOne (VW Fiber) 19151 23 Mzima 25973 23 LeaseWeb 16265 22 https://www.euro-ix.net/tools/asn_common It is feasible to peer at many Internet exchanges. Scale is the key – the bigger your network is, the more exchanges you may peer at. Don’t focus only on the price, there other advantages. Peering is not a religion, always consider pro’s and con’s. Thank you very much, and happy peering! ? .

  • Detecting Botnets Using File System Indicators
    Detecting botnets using file system indicators Master's thesis University of Twente Author: Committee members: Peter Wagenaar Prof. Dr. Pieter H. Hartel Dr. Damiano Bolzoni Frank Bernaards LLM (NHTCU) December 12, 2012 Abstract Botnets, large groups of networked zombie computers under centralised control, are recognised as one of the major threats on the internet. There is a lot of research towards ways of detecting botnets, in particular towards detecting Command and Control servers. Most of the research is focused on trying to detect the commands that these servers send to the bots over the network. For this research, we have looked at botnets from a botmaster's perspective. First, we characterise several botnet enhancing techniques using three aspects: resilience, stealth and churn. We see that these enhancements are usually employed in the network communications between the C&C and the bots. This leads us to our second contribution: we propose a new botnet detection method based on the way C&C's are present on the file system. We define a set of file system based indicators and use them to search for C&C's in images of hard disks. We investigate how the aspects resilience, stealth and churn apply to each of the indicators and discuss countermeasures botmasters could take to evade detection. We validate our method by applying it to a test dataset of 94 disk images, 16 of which contain C&C installations, and show that low false positive and false negative ratio's can be achieved. Approaching the botnet detection problem from this angle is novel, which provides a basis for further research.

  • Winter 2020 Colocation Services
    2020 WINTER CUSTOMER SUCCESS REPORT COLOCATION SERVICES CATEGORY COLOCATION SERVICES OVERVIEW Colocation services allow businesses to host their data in a third-party data center that has privately-owned networking equipment and servers. Instead of maintaining servers in-house, at a private data center, or in offices, enterprises can elect to co-locate their infrastructure by renting space in a colocation center. Unlike other types of hosting where clients can rent server space owned by a hosting vendor, with colocation, the client owns the server and rents the physical space needed to house it in a data center. The colocation service rents out data center space where clients can install their equipment. It also provides the cooling, IP address, bandwidth, and power systems that the customer needs to deploy their servers. 2 Customer Success Report Ranking Methodology The FeaturedCustomers Customer Success ranking is based on data from our customer reference Customer Success Report platform, market presence, web presence, & social Award Levels presence as well as additional data aggregated from online sources and media properties. Our ranking engine applies an algorithm to all data collected to calculate the final Customer Success Report rankings. The overall Customer Success ranking is a weighted average based on 3 parts: Market Leader Content Score is affected by: Vendor on FeaturedCustomers.com with 1.

Introduction One of the most important trends in internet governance in recent years has been the growth of internet blocking as a policy tool, to the point where it is increasingly becoming a global norm. This is most obvious in states such as China where blocking is used to suppress political speech; however, in the last decade blocking has also become more common in democracies, usually as part of attempts to limit the availability of child abuse images.
