Buidling Lifecycle Service Orchestration



The market for communication services is rapidly evolving and carriers must find better ways to interface their networks, says Mark Daley, Director of Digital Strategy for Epsilon. Better tools for interworking with customers are also needed. Automation will be key.

SD-WAN -- Threat or Opportunity?



Is SD-WAN a threat to carriers because users may leave their networks, or is it an opportunity?  It's both, says Prayson Pate, Chief Technology Officer for the Ensemble division at ADVA Optical Networking.

Barefoot's Deep Insight monitoring leverages P4 programmable switching silicon

Barefoot Networks, a start-up developing user-programmable switching chips, introduced a network monitoring system designed to provide visibility into every packet in a network.

The Barefoot Deep Insight software, which can run on commodity servers and in a network powered by switches based on Barefoot’s "Tofino" programmable switch chip, can interpret, analyze and pinpoint packet telemetry. Using stateful baselining of a network's performance, the company says its software automatically filters out irrelevant data, detecting only anomalies at any time scale and with nanosecond resolution. The Deep Insight software is able to track the sequence of switches the packet visited along its path, the set of rules it matched upon at every switch along the way, the time it spent buffered in every switch, to the nanosecond, and the packets, flows and application that the packet shared each queue with.

“Network monitoring is still stuck in the dark ages,” said Nick McKeown, co-founder and chief scientist at Barefoot Networks. “To get detailed visibility, some network owners are forced to deploy a second network that costs more than the first, just to watch what their network is doing. With Deep Insight, every switch in the network gathers data for you without any additional hardware, and without generating additional traffic. Deep Insight sits at the network edge, detecting and reporting network anomalies.” 

Barefoot is offering the network monitoring system on a pay-as-you-grow model, where customers pay only for the volume of telemetry they need.

Barefoot said its Deep Insight system could be especially useful in enterprise data centers, where many-to-one traffic patterns associated with applications such as Hadoop and HDFS can result in congestion, queue build-up and increases end-to-end latency. The Tofino switching silicon can detect the queue build-up and take a snapshot of every packet header during the congestion event. The Deep Insight software could then be used "to visualize the full dynamic of a congestion event, down to each individual packet, exposing the aggressors and the victims flows."

Barefoot is also highlighting the P4 programmability of its Tofino chip. This provides the flexibility to design for specific use cases without writing data plane code or modifying the silicon.


Alibaba, AT&T, Baidu, Tencent adopt Barefoot forwarding plane


Barefoot Networks, a provider of advanced, high speed switching technology, announced significant market momentum driven by growing demand for its programmable forwarding plane technology.Barefoot's 6.5 Tbit/s Tofino switch, which is claimed to be the fastest and P4-programmable switch chip, has been sampling to customers since the fourth quarter of 2016. The company noted that its technology is being adopted by large enterprises and telecommunications...


Ekinops debuts flexible line rate modules

Ekinops based in Lannion, France, a global supplier of next-generation optical networking equipment, introduced two new flexible rate line modules for its optical transport platform in metro, regional or long-haul deployments.

The two new modules – the PM 200FRS02 and PM 200FRS02-SF – employ dual QSFP28 client ports with software-selectable line side modulation that can be provisioned as either DP-QPSK or 16QAM to create 100G or 200G transport links. The new generation modules occupy only one-third the space of previous equipment, occupying only a single slot in an Ekinops 360 chassis, for three times the capacity per shelf. This makes it possible to fit up to 1.2 terabits per second of capacity in only two rack units. In addition, the PM 200FRS02-SF provides single fiber operation, giving service providers the option of cutting fiber costs in half.

Ekinops is also adding to the flexibility of the modules by introducing the PM 100G-AGG companion card for multiplexing up to ten 10G multiprotocol client services into a G.709 standard OTU4 that connects to one client port on the PM 200FRS02 or PM 200FRS02-SF.

Ekinops said its new modules will help service providers to reduce their capital and operational costs, improving the business case for deploying new capacity.

Aire Networks, which is Spain's fourth largest wholesale operator, is now using the Ekinops modules in its 27,000-kilometer fiber network that covers 90 percent of the country. The single fiber capability was key for Aire Networks, which was looking for a solution supporting 200G transmission in single fiber mode.

“We have been able to reduce the form factor in these new modules by a factor of three while reducing power requirements by a factor of two. That delivers an order of magnitude improvement in service density and network cost, key factors for Aire Networks and for other Ekinops customers when it comes to profitability,” said Mark Burton, EMEA Vice President of Sales at Ekinops. “This demonstrates Ekinops’ continued commitment to providing our customers the most efficient and flexible optical transport solutions.”


Japan Internet Exchange deploys Coriant Groove G30

Japan Internet Exchange Co. has deployed the Coriant Groove G30 Network Disaggregation Platform to scale network capacity in its Tokyo and Osaka metropolitan area networks and support the cost-efficient delivery of high-performance interconnect services, including 10G, 40G, and 100G.

Coriant’s strategic local partner is UNIADEX Ltd.

“JPIX is playing a vital role as the core of Japan’s Internet with an advanced network infrastructure optimized for the stringent demands of an evolving application landscape that includes IoT and 5G,” said Petri Markkanen, Managing Director, Asia Pacific, Coriant. “We are pleased to be working closely with this industry-leading Asian IX provider and are committed to helping JPIX further enhance connectivity services and network efficiencies for their end-user customers.”

T-Mobile and Ericsson push Licensed Assisted Access to 1.1 Gbps

In a demo conducted at  T-Mobile's lab in Bellevue, Washington, T-Mobile and Ericsson achieved speeds of 1.1 Gbps using 12-layer Licensed Assisted Access (LAA) technology.

The set-up sued Ericsson's Radio System and the TM500 network test equipment from Cobham Wireless. The test combined several LTE technologies including 256 QAM, 4x4 MIMO, and LAA by aggregating two licensed carriers and three unlicensed carriers.

The Ericsson Radio 2205 delivers LTE on the 5GHz unlicensed band in outdoor micro cell environments. Using LAA, the unlicensed carriers can be aggregated with licensed carriers on the micro cells or on nearby macro cells.

The companies claim this to be the first demo in the world to hit speeds beyond the 1 Gbps threshold on unlicensed spectrum.

“Breaking the 1 Gbps-mark means that commercial gigabit speeds are not far from reality for many broadband users, with our LAA and MIMO technologies as key enablers. It is also an example of how innovatively we work with partners to push the boundaries of technology and achieve new milestones,” said Fredrik Jejdling, Executive Vice President and Head of Networks at Ericsson.

Neville Ray, Chief Technology Officer for T-Mobile, says: “T-Mobile has built the nation’s fastest LTE network by innovating and bringing new technologies to market for our customers. This LAA technology builds upon our deployments of 4x4 MIMO and 256 QAM and will give customers even greater access to near gigabit speeds in 2018.”

Qualcomm targets Windows 10 on Snapdragon

Qualcomm and Microsoft confirmed progress made over the last several months to deliver Windows 10 on Snapdragon. The idea is to use mobile phone processors to run light notebooks.

The first Windows on Snapdragon device will be a 2-in-1 convertible ASUS NovaGo that is expected to hit the market early next year.

A second device will be a detachable HP ENVY x2 Windows on Snapdragon Mobile PC.

Both will be fanless design and will offer support for Gigabit LTE connectivity.

Later this week, Qualcomm is expected to preview its next-gen Snapdragon 845 Mobile Platform.
