The London Internet Exchange (LINX) announce new partnership with Colt Data Centre Services

By | LINX News
LINX have recently welcomed Colt Data Centre to their London network as a Transmission PoP. The new partnership offers Colt customers a valuable, new additional service and prospective LINX members an attractive new location to peer in West London.
A Transmission PoP is a facility physically based within a carrier neutral data centre that provides customers with direct access to LINX’s infrastructure and improved performance of their peering connectivity.Matthew Cantwell, Director of Product for Colt DCS commented:“We are delighted with the addition of a LINX transmission POP to our London West data centre. Along with a wide choice of alternative carriers, our customers see direct access to Internet Exchanges as a crucial element of their network strategy. We look forward to working closely with LINX to help our customers and prospects benefit from the capabilities of our site and connecting directly to the UK’s premier Internet exchange.”

As well as improved latency and resilience, Colt customers who become LINX members will also benefit from improved routing control, increased capacity and redundancy at lower cost. In addition, there is also the opportunity to peer with over 820 member ASNs from over 75 countries worldwide on LINX’s dual peering Local Area Networks (LANs) LON1 and LON2, a facility unique to the UK.

Jennifer Holmes, Head of Sales at LINX commented:

“We are really excited to be partnering with Colt for the launch of a new Transmission PoP in London. This will allow even more networks to connect to our peering platforms in the capital from a location that is rapidly growing in importance. It is a very positive step for the network community here.”

Route server Validation Goes Live in Manchester

By | LINX News
At its most recent membership meeting LINX99 in November, LINX updated the membership on the status of the route validation project.
At its membership meeting LINX96 in February 2017, The London Internet Exchange (LINX) announced the plans for deploying route validation at all its route servers. After the discussions with the membership in February LINX had agreed on a two stage approach, firstly invalid prefixes would be tagged and then after a short period the tagged prefixes would no longer be propagated. Any member who wished to receive all data would always have the option to request such data.LINX’s caution came from concerns that once initial validation was put in place the quantity of invalid prefixes was very large. To mitigate this risk LINX embarked upon an individual programme with their NOC team to contact all members who were announcing invalid prefixes or leaking routing tables to inform them of the route server project to help them correct the issue (namely correcting information held in PeeringDB, and other databases). Contacting members has had some impact on the number of invalid prefixes being announced, but surprisingly it is still around 20% of the total prefixes.

At its most recent membership meeting LINX99 in November, LINX updated the membership on the status of the route validation project. LINX informed that the next step was to start to implement the route tagging, as originally agreed with the members, and that this was due to start the same week as LINX99. After a short discussion with the members following the announcement it became clear that the members now preferred for LINX to go straight to a non-propagated approach. The majority of members present thought that a two staged implementation would not be effective as members would have to build their own filters based upon the LINX tagging. This work would then become redundant when LINX started not to propagate tagged prefixes and as a result most of them wouldn’t build their own filters. As for members who were announcing invalid prefixes, whilst the number of routes were high, the number of members that this represented was not as significant.

LINX CMO, Kurtis Lindqvist, posed the question directly to the room regarding which approach would LINX should take. It was agreed that the roll out should be by individual route servers with non-propagation being in place almost immediately after the tagging is announced. The first route server to go through this process is at IXManchester, with LINX enabled tagging of prefixes with communities based on the result of prefix validation, beginning on Tuesday 28th November. At this first step, LINX will be using the IRR object registered in PeeringDB to check for valid IRR entries for the announced prefixes. In addition, LINX check for a valid ASN origin.

On Wednesday 29th November, LINX changed the default configuration on rs1.man1 (quagga) and will no longer propagate any prefixes which do not pass the prefix validation. On Monday, 11th December, LINX will change the default configuration for rs2.man1 to match that of rs1.man1.

If for whatever reason, members want to continue to receive the unfiltered prefixes, they can opt-out of this change by opening a ticket with the LINX NOC, stating their IXManchester peering LAN IP address and ASN.

Similar changes will be applied to the LINX route servers on all LANs over the next few weeks. If members are using LINX route servers then they are encouraged to look out for further announcements on the LINX ops-announce mailing list.

The aim of this project is to capture and reduce all non-malicious errors and reduce member issues caused by prefix leaks. Validating against the IRR database means that it becomes very important that all members have correct and current information in PeeringDB. LINX has always stressed the importance to members of registering their information on PeeringDB, but as this project becomes live, it is now critical. LINX are urging all members to check and update their information to ensure that it is correct.

As a future improvement, LINX are also evaluating the use of additional checks, i.e. the use of RPKI to further improve the platforms.


LINX Confirms Successful Testing of New Disaggregated Networking Technology

By | LINX News
The London Internet Exchange (LINX) has announced a series of successful Proof of Concepts (POCs) following a decision just over a year ago, to adopt a new and revolutionary, disaggregated approach to their secondary LAN network architecture, LON2.
In August 2016, after months of research with potential new suppliers, a decision was made to source hardware from Edgecore Networks and software from IP Infusion to compliment this approach. The LON2 architecture programme has since gathered pace, particularly over the last six months, now bringing LINX to the point of deployment.When deciding on the disaggregated technology stack presented by Edgecore and IP Infusion, it was known that EVPN services would need to be built into IP Infusion’s OcNOS software. This was because the system has traditionally been a datacentre centric solution, so compatibility with LINX’s inter-site service provider type architecture using Edgecore hardware was required.A number of collaborative proof of concepts took place over the summer, resulting in a code base and hardware solution that is fit for purpose at a multi-site Internet exchange point (IXP). LINX moved through the deployment phase in October and November, leading to member testing in December. Work will continue through the customary change freeze period at the end of the year with the migration of services taking place as soon as practical at the start of 2018.

LINX Chief Technical Officer, Richard Petrie, says:
“In undergoing the process of selection, testing, refinement and deployment phases of these new systems, we faced a number of technical and non-technical challenges. The life cycle management of a disaggregated deployment is a new concept to us, as it is with many businesses coming under the service provider operating model. The performance and commitment of both IP Infusion and Edgecore Networks has been fundamental in allowing all three organisations to be able to collaborate, test and resolve complex issues effectively and efficiently.”

Mr Petrie added, “We are very pleased with the results so far and are excited to be implementing the technology and test our products and services in preparation for member migration.”

New partners Edgecore Networks and IP Infusion have now been awarded contracts following the series of successful PoCs and are looking forward to the next stage of the project;

“LINX is demonstrating that open network disaggregated systems are ready for deployment outside of the data centre, affording the benefit of data centre transformation to other network applications. IP Infusion and Edgecore Networks have worked closely with the LINX engineering team to test and validate the system can meet their member and operational needs. We are delighted to move to the next stage with LINX.” Mark Basham, Vice President Edgecore Networks EMEA.

“With OcNOS, LINX can easily design their disaggregated network to meet their specific needs and deploy new services quickly. We continue to look forward to partnering with LINX to meet the growing demands of their new platform and to help keep operating costs low.” Atsushi Ogata, President and CEO of IP Infusion

LINX operates a unique, dual LAN network within the London metro LON1 and LON2, spanning 10 datacentre locations. The primarily London-based exchange strives to remain at the forefront of technology and therefore chose to lead the way by restructuring LON2, benefiting their members from both a resiliency and long-term value perspective.

LINX members and those interested in joining the exchange are attending the next quarterly member conference taking place in London on Monday 20th and Tuesday 21st November, where a full update on the project will be presented. Find out more at

Djibouti Telecom connects its IP network to LINX

By | LINX News
Djibouti Telecom, a leading East African telecom operator, has joined LINX, the first network from that country to do so
Djibouti Telecom, the sole voice and data services provider in Djibouti and a leading IP transit service provider in the East Africa region, have joined LINX. They are first member to join the exchange from the country taking the number of territories represented at the exchange to 75.

With this new membership, Djibouti Telecom IP networks and Internet service providers will have access to many of the most attractive peers at a lower cost. As a result, both new and existing customers will be able to experience reduced latency, increased resilience and reduced costs.

Djibouti Telecom say:

The massive data growth projections for East Africa have prompted a rethink of the industry’s business model, with Djibouti Telecom focused on ensuring Internet traffic is transported and managed across a reliable, diverse and secure network. That is why joining LINX is a key element to Djibouti Telecom’s strategy in providing greater value and a better Internet experience to its customers.

LINX met with Djibouti Telecom at the Capacity Middle East event in in March and following the application and connection process they were able to begin passing traffic at the exchange in September. They are connected at Telehouse North in the London’s Docklands on the LON1 network via LINX’s ConneXions programme.

2017 IXManchester DNS Training & Karting Event to bring networking community together

By | LINX News
It was announced at the LINX98 member conference that LINX will be staging another IXManchester training, networking and karting event on Tuesday 17th October.
The 2017 training and karting event, which will again be held at Daytona Manchester in Stretford, has been organised in conjunction with the IXManchester steering committee and Systems & Network Training. This year’s training is focussed on DNS and DNSSEC. By the end of the session delegates will be able to explain how DNS and DNSSEC work and will benefit anyone new to DNS or anyone looking to expand their knowledge on the subject.
The event is technical but non technical people have benefited from the session before. As the session is only two hours long it is fast paced.In addition to the training, a networking lunch and karting social has been arranged to enable Internet professionals to meet and discuss ideas and future plans for peering in the region.

Feedback from last year’s BGP training included the following comment:“I really enjoyed the karting yesterday and found the BGP training useful…was a good taster and we might get the full training from those guys”. 

LINX announce price cuts of up to 40% on port fees at IXManchester

By | LINX News
LINX, the leading European provider of Internet interconnect services, announced at the LINX98 member conference on 21st August that it is to significantly reduce 10GE and 100GE port fees at its regional exchange, IXManchester.

Monthly 10GE port prices will be cut by 22.8% to £270 with 100GE fees reduced by over a third to £1350 (39.3%). In addition, the first 1GE port at IXManchester is available at no charge and comes as part of LINX membership. These prices will to come into effect from 1st October 2017.

Established in 2012, IXManchester is rapidly approaching 100 connected networks who pass a combined 35Gb/s of traffic at peak times. This makes IXManchester the biggest peering LAN in the UK outside of London and an attractive alternative to peering in the capital. LINX CEO, John Souter, said:

“Last year we implemented mid-year price cuts of up to 40% while simultaneously announcing plans of a major upgrade of our LON2 network in London. The introduction of new LON2 equipment allows us to re-deploy the original hardware into our Manchester sites as part of our long-term support for regional peering in the UK.”

IXManchester operates across three city locations; Equinix Williams House, Equinix Joule House plus the M24Seven data centre in Stretford. Chris Byrd, Technical Director at M24Seven, said:

“IXManchester is very well established now and M24Seven is proud to have been host to one of the exchange’s three city sites for the past three years. The decision to reduce prices is great news for the networking community in the region and will help further enhance Manchester’s status as a leading tech city.”

Last year, Manchester made it into the top 20 European Digital City Index for starting and scaling a digital tech business. In addition, £10million in government funding is being proposed for a future project to test IoT technology.

Creating a buzz for LINX98 Manchester

By | LINX News
The LINX98 member conference is just around the corner, taking place at Manchester Central Convention Complex on 21st and 22nd August. To help create a ‘buzz’ for the event, here’s a sneak peek at the branding style we’re using for our T-Shirt giveaway!
If you’re not familiar with the ‘Manchester Bee’ it was adopted as a motif for the city during the Industrial Revolution. This was at a time when Manchester was taking a leading role in new forms of mass production which lead to it becoming the world’s first industrial city. The Bee gained a global presence more recently as it came to symbolise the strength of the city following the tragic terror attack earlier this year.Manchester is known for being a ‘hive’ of activity and this spills over into it’s current digital status within the UK.

The city is home of LINX’s first regional Internet exchange point, IXManchester and last year, made in to the top 20 European Digital City Index for starting and scaling a digital tech business. In addition, £10million in government funding is being proposed for a future project to test IoT technology*.
