Facebook open sources Katran, its network load balancer

Facebook is releasing its Katran forwarding plane software library, which powers the network load balancer used in Facebook's infrastructure.

Facebook said that by sharing Katran with the open source community, it hopes others can improve the performance of their load balancers and use it as a foundation for future work.

Katran is deployed today on backend servers in Facebook’s points of presence (PoPs). Katran offers a software-based solution to load balancing with a completely reengineered forwarding plane that takes advantage of two recent innovations in kernel engineering: eXpress Data Path (XDP) and the eBPF virtual machine.

EllaLink submarine cable system to connect Brazil to Europe

EllaLink, a proposed submarine cable system promises to bring the most direct fiber connectivity between Brazil and Europe.

EMACOM - Telecomunicações da Madeira - announced the signing of a contract to develop the system with direct links to the islands of Madeira. The expected ready-for-service is 2020.

EllaLink will be a 3 fiber pair systems linking Southern Europe (Sines – Lisbon – Madrid) to LATAM (Fortaleza – Sao Paulo). Three intermediate branches are also being planned to land in Cabo Verde, the Canary Islands and Madeira. The main section of the cable traveling from Sines to Fortaleza is approximately 5900 km.

Nordic countries seek the lead in 5G

The five Nordic countries are seeking to take a global lead in the rollout of 5G.

A vision of how to capture this leadership role was set out in a meeting of prime ministers this week in Örnsköldsvik, Sweden.

A key pillar is cooperation on spectrum, policy, and test beds across all five countries -- Finland, Sweden, Norway, Denmark and Iceland.

The prime ministers are calling on the digitalisation ministers of each country to take the lead in following up their joint declaration.

“The Nordic region is one of the most innovative regions in the world. The development of 5G is progressing quickly and the Nordic region will be at the fore of this development. It creates jobs and prosperity in our countries,” says Prime Minister Stefan Löfven.

Platform.sh raises $34M for enterprise cloud

Platform.sh, a start-up based in Paris with offices in San Francisco, raised $34 million in a Series C funding for its "idea-to-cloud" application platform.

Platform.sh simplifies deployments for enterprises by combining an automated cloud with its unique rapid cloning technology that can instantly spin up and deploy exact clones of entire live web applications in less than 60 seconds, allowing development teams to ensure that new features do not break when in production. Its product can be used to develop, test, deploy and run their cloud-based web applications with speed and confidence. The company claims more than 650 enterprise customers across the globe are currently using its platform and says sales have grown 110 percent this year.

The funding round was U.S.-based Partech and included Idinvest Partners, Benhamou Global Ventures (BGV), SNCF Digital Ventures and returning investor, Hi Inov.

“The customer traction and organic growth we’ve seen over the past 12 months – especially in North America – made it clear that we are ready to scale on a global level,” said Frederic Plais, CEO of Platform.sh. “The productivity gains that our platform delivers are beyond anything offered by managed hosting solutions, or DIY approaches with cloud infrastructures. The recent years have seen an explosion of incredibly strong tools that help implement novel cloud architectures, but the mainline approach is patchwork and piecemeal. Platform.sh proposes a unified model that transcends categories, not only solving difficult cluster orchestration and continuous delivery problems, but also improving testing and quality assurance of applications.”

Kaiam partners with Broadex to manufacture optical modules in China

Kaiam, which is a leading supplier of optical transceivers for hyperscale data centers, signed a memorandum of understanding (MOU) with Broadex concerning the volume production of QSFP28 100G-CWDM4 transceivers in China based on Kaiam’s LightScale2 platform.

Kaiam says its LightScale2 architecture offer fundamental advantages in cost and performance and is ideally suited for high-volume applications.

The agreement allows Broadex to manufacture these units in China and directly address Chinese customers who require local production. This also complements Kaiam’s in-house manufacturing in the UK and provides further capacity to address the high volume data center market.

Broadex Technologies is located in Jiaxing, Zhejiang Province, and operates an R&D center in Shanghai. Its product portfolio includes PLC splitters, arrayed waveguide gratings (AWGs), variable optical attenuators (VOAs), Variable Optical Power Multiplexer (VMUX), and optical sub-assembly (OSA) for transceivers.

“We anticipate very strong demand for 100G transceivers based on our LightScale2 technology,” said Dietmar Zapf, GM / VP of Manufacturing at Kaiam. “In addition to the production lines already running at our Livingston, UK facility, we need to develop and secure further expanded capacity for manufacturing these products in high volume. The MOU signed with Broadex would allow us to leverage Broadex’s manufacturing expertise and infrastructure and expand our capacity in the next 3–6 months to meet high demand.”

“We are glad that Kaiam chose to continue working with us for manufacturing its new non-hermetic transceivers for data center applications,” said Yong Ding, PhD, VP and CTO of Broadex Technologies. “We have been producing OSA-level components for Kaiam in high volumes for several years now. The LightScale2 platform is optimized to deliver maximum value and performance in the data center environment at dramatically lower costs. We will work aggressively to quickly ramp to high volumes with high yields.”

Kaiam debuts 400G QSFP-DD

Kaiam unveiled an 8-lane, single-mode 400G transceiver in a QSFP-DD form factor at OFC 2018.

The new device, which is enabled by the company's LightScale2 architecture used in its XQX5000 series of 100GBASE-CWDM4 QSFP28 pluggables, is optimized for high-volume, low-cost manufacturing.

The company said its LightScale2 platform supports both 4-lane and 8-lane 200G and 400G transceiver variants, including 400G-LR8/FR8, 400G-FR4, 2x100G-LR4, 2x100G-CWDM4, 2x100G-4WDM-10, 200G-FR4, and 2x200G-FR4. These can be supported in either QSFP-DD or OSFP packages. The platform can further extend to future 800G solutions, and even beyond pluggables to Kaiam’s Co-Packaged Photonics Interconnect (CoPPhI).

“As capacity and density requirements increase in the data center, our MEMS-based PLC approach further outperforms traditional approaches,” commented Bardia Pezeshki, CEO. “At OFC 2018, we are demonstrating a transceiver that has 4x the bandwidth of the previous generation in roughly the same QSFP form factor, highlighting the bandwidth and density scalability of Kaiam’s technology.”

“We’re seeing market need for 400G QSFP-DD transceivers in 2019, but uncertainty and skepticism about whether transceiver vendors can deliver cost-effective solutions at scale with the high speeds needed per lane and the desired reach. Our ability to offer a simple 8-channel 400G solution in advance of the more complex 4-channel electronics, with the full 10km reach, gives the customers faster and easier access to 400G in the desired compact form factor,” commented Jeremy Dietz, VP of Global Sales & Marketing.

Chirisa said designs are being finalized for a first phase $225m development of a 280,000 SF, 30 MW Tier III facility to meet the phenomenal demand in the US's hottest data center market/

Telia Carrier activates PoP in Belgrade

Telia Carrier activated its first Point-of-Presence (PoP) in Belgrade, Serbia, enabling customers to connect directly to the Telia Carrier backbone

The Belgrade PoP will also serve as a connectivity hub for surrounding countries, improving the availability of high-speed IP Transit, Cloud Connect, Ethernet and IPX services. It will also provide a transport interconnection point for international customers requiring a dedicated connection into Serbia.

"The appetite for online services, in both a business and consumer context, has reached a point in Serbia where we saw a compelling need to expand our network into the region. Many of the world’s leading telcos, cloud and content providers already connect directly to the Telia Carrier backbone and this expansion brings our customers in Serbia and the surrounding countries ever closer to the content and services they need," stated Henrik Almroth, Sales Director at Telia Carrier.
