New LINX Bi-Di Optical Transceiver Product Goes LIVE as First Connexions Partner Upgrades

By | LINX News
Back in April 2017, The London Internet Exchange announced the availability of a new fibre product in the form of Bi-Directional Optical Transceivers, at their regional exchange IXManchester.
LINX member, reseller partner and data centre operator, TeleData, were keen to announce to fellow peers at the exchange last week, that they had successfully upgraded their 10G port to the new Bi-Di optic, being the first member at the exchange to do so.  As a LINX Connexions Partner, this upgrade immediately enables customers at their own data centre, Delta House in Manchester, to take LINX connections with greater capacity and it has also allowed an additional connection utilising fibres already in place, removing the need for extra cross connects.Matthew Edgley, Commercial Director of TeleData says:“The main thing for us and the customer was being able to provision an additional high capacity LINX port from our data centre, without expensive third-party cross connect fees that are charged to connect into the core LINX PoP at the other end; which could have made the customer connection cost prohibitive.  We provided the customer’s cross connect at TeleData free of charge as we’d rather promote and enable LINX connections and member expansion from our data centre, than put cost barriers in the way.”

“We hope this will encourage more potential LINX members to see the advantages and join the exchange via a Connexions partner and data centres such as ours.”

When joining LINX, most members connect using a fibre pair or cross connect. One fibre is dedicated to receiving data from network equipment and the other fibre will be dedicated to transmitting data to the network. The new product, Bi-Directional Optical Transceivers (or Bi-Di transceivers for short) allows both the transmitting and receiving of data on a single fibre resulting in the benefit of reduced interconnect cost for the member, whilst doubling the capacity of each cross connect.

TeleData customer and LINX member Boundless were the first to use the new Bi-Di optical link at their IXManchester location, Williams House, and have successfully migrated their peering over.

Chris Bewley, Technical Director from Boundless says:

“The use of Bi-Di transceivers has enabled us to take a new 10G port at IXManchester, giving us future regional peering capacity as we continue to grow our network. Previously, the cost of third-party cross connect fees at Williams House would have been prohibitive to us taking the new port in IXManchester.”

“The order process was straight forward and we are seeing good, stable connectivity to the exchange from our equipment in TeleData.”

LINX’s Bi-Directional Optical Transceiver service is currently only available at IXManchester, however, there is an expectation that this product will be rolled out to all LINX exchanges, including both London LANs, in the future.

New Partnership for Angola Cables and LINX

By | LINX News
Wholesale carrier Angola Cables has launched a remote peering service to improve the connectivity between the peering community at The London Internet Exchange (LINX) and the peering members at its own Internet exchange point.
Angola Cables is a partner in the development of data centers in Luanda and Fortaleza, Brazil, and in the building of the South Atlantic Cable System (SACS) undersea cable, the first direct subsea link between Africa and South America in the southern hemisphere.Earlier this month, Angola Cables confirmed progress in construction of the 6,500-km undersea cable with an official launch in Sangano, Angola (see “Angola Cables announces launch of South Atlantic Cable System”). When finished, the SACS will position Angola Cables as a global interconnection provider by linking to Angola Cable’s European system and eventually to the Middle and Far East.”Peering at LINX in London and offering a remote peering service is part of the ongoing development of our network to ensure that our customers and partners have access to the latest communication technology and retain us as their ideal partner for international connectivity and high-quality Internet services,” said Darwin Costa, Angola Cables Product Manager.

“Since joining LINX peering community as one of the first exchange points, we have seen a more than threefold increase in traffic. We anticipate gaining new remote peering customers from across Africa and also from South America, once the South Atlantic Cable System is complete.”

The London Internet Exchange (LINX) is one of the largest Internet exchanges in the world, connecting over 825 member ASNs from over 75 countries around the globe. They are located in 10 PoPs across the UK capital along with regional exchanges in Wales, Manchester and Scotland. LINX also operates an Internet exchange in the Ashburn metro area in the US just outside Washington DC, LINX NoVA.

Jennifer Holmes, Head of Sales at LINX said; “We are delighted to welcome Angola Cables as our newest reseller partner and are looking forward to a long and successful partnership with them. This arrangement will provide African networks with a cost-effective and convenient method of connecting to LINX and enables them to enjoy the many benefits that peering in London has to offer.”

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”.
