KT Conducts First eMTC Field Trial with Nokia

KT and Nokia announced the industry's first eMTC field trial, marking an important milestone for the Internet of Things, allowing for coexistence with the existing LTE network as well as providing extended coverage.

eMTC, which is also referred to as LTE-M with 1.4MHz bandwidth, is a feature that will be fully standardized with 3GPP Release 13, the first evolution step of LTE-Advanced to LTE-Advanced Pro. eMTC will provide data rates of up to 1Mbps and up to four times better coverage, while reducing device complexity by up to 80%, in comparison to conventional LTE. This allows for cost-effective connectivity of more data-rich sensors, such as environmental monitoring or building surveillance, on existing LTE networks located in rural areas and buildings.

The test was conducted on KT's LTE network using Nokia's Flexi Multiradio 10 Base Station. eMTC utilized only 1.4MHz of the full 20 MHz LTE system, leaving the remaining spectrum free for normal LTE traffic.

Chang Seok Seo, Senior Vice President and Head of Network Strategy Unit, KT, said: "This trial, a world-first, offers a solid platform to promote the widespread application of services powered by IoT technology by addressing limitations that are hampering its spread and reach. Together with Nokia, we will play a pivotal role in pioneering the emergence of IoT as the first-choice technology in Korea and beyond."

Andrew Cope, Head of Korea, Nokia, said: "This project underlines our position as a driving force behind the creation of a programmable world, where close to 50bn devices* will be connected in 2025. With this trial, we have successfully demonstrated the capabilities of LTE as a veritable backbone for a growing range of IoT use cases."

IHS:Downtime Costs $700 Billion a Year for U.S. Businesses

Information and communication technology (ICT) downtime is costing North American organizations $700 billion per year, according to a new study from IHS.

Some highlights:

  • Network interruptions are the biggest culprit of downtime and have far-reaching consequences: applications, servers and devices may all be working fine, but they can’t communicate with each other when the network is down
  • On average, survey respondents experience 5 downtime events per month, and 27 hours of downtime per month
  • Organizations are making changes to reduce the impact of downtime, from investing in early-detection capabilities to improving redundancy, training and hiring new people, and implementing backup processes that don’t rely on ICT systems

“Our research found that the cost of ICT downtime is substantial, from $1 million a year for a typical mid-size company to over $60 million for a large enterprise,” said Matthias Machowinski, research director for enterprise networks and video at IHS.

Blueprint: Five Things You Didn’t Know You Could Do With DNS

by Shannon Weyrick, Director of Engineering for NS1

Over the past 25 years there have been dramatic shifts in how companies deliver websites and applications. The pervasiveness of globally distributed cloud computing providers like AWS and Digital Ocean, along with the rise of Infrastructure as a Service (IaaS) and deployment automation, have dramatically reduced the costs and complexities of deploying applications. Users today can deploy servers in different parts of the world in minutes and leverage a multitude of software frameworks, databases and automation tools that all work to decentralize environments and improve uptime and performance.

The result is one of the more fundamental changes in the recent history of computing: today’s applications are distributed by default.

Unique Traffic Management Challenges for Modern Applications

While we’ve seen significant progress toward distributing applications on the infrastructure and application side, the tools website operators have at their disposal to effectively route traffic to their newly distributed applications haven’t kept pace. Your app is distributed, but how do you get your users to the right points of presence (POPs)?

Today, traffic management is typically accomplished through prohibitively complex and expensive networking techniques like BGP anycasting, capex-heavy hardware appliances with global load balancing add-ons, or by leveraging a third party Managed DNS platform.

As the ingress point to nearly every application and website on the Internet, DNS is a great place to enact traffic management policies. However, the capabilities of most Managed DNS platforms are severely limited because they were not designed with today’s applications in mind. For instance, most managed DNS platforms are built using off-the-shelf software like BIND or PowerDNS, onto which features like monitoring and geo-IP databases are grafted.

Until recently, a state-of-the-art DNS platform could do two things with regards to traffic management: first it wouldn’t send users to a server that was down, and second it would try to return the IP address of the server that’s closest to the end user making the request.

This is a bit like using a GPS unit from 1999 to get to a gas station: it can give you the location of one that’s close by and maybe open according to its Yellow Pages listing, but that’s about it. Maybe there is roadwork or congestion on the one route you can take to get there. Maybe the gas station is out of diesel, or perhaps they’re open but backed up with lines stretching down the block. Perhaps a gas station that’s a bit farther away would have been a better choice?

High-performing Internet properties face similar challenges in digital form, and they go far beyond proximity and a binary notion of “up/down.” Does the datacenter have excess capacity? What’s traffic like getting there - is there a fiber cut or congestion to a particular ISP we should route around? Are there any data privacy or protection protocols we need to take into account?

Intelligent DNS

Today’s data-driven application delivery models require a new way of managing DNS traffic. Next-gen DNS platforms have been built from the ground up with traffic management at their core, bringing to market exciting capabilities and innovative new tools that allow businesses to enact traffic management in ways that were previously impossible.

Here are five best practices to consider when implementing an advanced, intelligent traffic management platform:

  1. Intelligent routing: Look for solutions that route users based on their ISP, ASN, IP prefix or geographical location. Geofencing can ensure users in the EU are only serviced by EU datacenters, for instance, while ASN fencing can make sure all users on China Telecom are served by Chinacache. Using IP fencing will make sure local-printer.company.com automatically returns the IP of your local printer, regardless of which office an employee is visiting.
  2. Leverage load shedding to prevent meltdowns: Automatically adjusting the flow of traffic to network endpoints, in real time, based on telemetry coming from endpoints or applications, can help prevent overloading a datacenter without taking it offline entirely, and seamlessly route users to the next nearest datacenter with excess capacity.
  3. Enact business rules: Meet your applications’ needs with filters that use weights, priorities and even stickiness by enacting business rules. Distribute traffic in accordance with commits and capacity. Combine weighted load balancing with sticky sessions (e.g. session affinity) to adjust the ratio of traffic distributed among a group of servers while ensuring that returning users continue to be directed to the same endpoint.
  4. Route around problems: Identify solutions that provide the ability to constantly monitor endpoints from the vantage point of the end user and then send those coming from each network to the endpoint that will service them best.
  5. Cloud burst: Leverage ready-to-scale infrastructure to handle planned or unplanned traffic spikes. If your primary colocation environment is becoming overloaded, make sure you're are able to dynamically send new traffic to another environment according to your business rules, whether it’s AWS, the next nearest facility or a DR/failover site.

 For businesses that need to deliver Internet-scale performance and reliability for high-volume, mission-critical applications, they must rethink their current DNS and traffic management capabilities. Traditional DNS technologies are fractured and rudimentary, making the industry ripe for disruption in order to accommodate today’s demanding applications.

Tomorrow’s modern distributed application delivery will be supported by converging dynamic, intelligent and responsive routing technologies. Whether you’re building the next big thing or you’ve already made it to the Fortune 500, best practices suggest that it’s time to evaluate current DNS and traffic management platforms with an eye on solving previously intractable problems and improving performance for webscale applications.
