Ethernet VPN (EVPN) - Networks for Ethernet Services

By: Greg Hankins, Senior Product Line Manager, Alcatel-Lucent

I’ve been talking a lot about EVPN recently at network operator conferences around the world, because I’m really excited about this new technology.  EVPN offers an alternative to VPLS that integrates both Layer 2 and Layer 3 services, and can run over simple IP networks with ECMP for resiliency and load balancing.  EVPN is an interesting new technology if you are providing a Layer 2 infrastructure over multiple sites, delivering integrated Layer 2/Layer 3 services, or providing cloud services.

Kabel Deutschland Simplifies its IP Edge

IP address exhaustion is an issue every Internet service provider must face. With the dwindling of IPv4 addresses, operators must migrate to IPv6 and seamlessly if they are to meet the needs of commercial, residential and mobile services.

For Vodafone Company Kabel Deutschland (KD), Germany’s largest cable operator, it was no question whether the move to IPv6 would be a bolt-on solution or something more integrated. A bolt-on solution would not do for KD, according to a recent Alcatel-Lucent case study on KD. The company needed to address the issue of flexibility to accommodate long-term growth and next generation service delivery without compromising its reputation for high-performance and high-value service.

Advancing Utility IP Migration Takes Time and Care

Mae Kowalke, TMCnet Contributor

This is the third in the three part series looking at how IP, which has been playing an important role in business transformation for some time, now has become critical to the utilities industry as it is leveraging the transformation of communications networks to IP to maximize smart grid deployments. In short, taking full advantage of things like smart metering and big data means to improve usage, real-time information and improved interoperability.

The future of the smart grid has unfolded slowly partially because adoption is more than a technology issue, and because while businesses want reliability, utilities demand it; a cautious IP migration is almost a given. In fact, part of the path to adoption goes through social challenges, not just technology investment.

IP Migration Picking Up Speed among Utilities

Mae Kowalke, TMCnet Contributor

A few years ago, the idea of a smart grid and things such as smart metering was the stuff of science fiction. But thanks to recent innovations, a utility that is not working on a migration to IP is behind the curve.

In this second of a three-part series on the value of the migration utility infrastructure to IP as the means to enable and enhance the value of smart grids, we look at an expert’s view of the challenges as highlighted in a recent GridTalk posting by Bart Vrancken, utilities solutions architect at Alcatel-Lucent, who noted, “Utilities telecom used to be very simple, handled in the background with a very small team…The explosive growth in intelligent grid devices with communication capabilities was not foreseen at all several years back. But now we see numerous examples of customers deploying these technologies.”

IP Network Investments Enable Enhanced Smart Grid Value

The future of the smart grid looks bright. Innovations such as IP/MPLS network connectivity and the desirability to all potential stakeholders in smart cities projects have helped propel smart grid spending in general and investment in the enabling networks. In addition, government programs such as the U. S. Smart Grid Investment Grant Program have pumped $7.8 billion into smart grid systems with accelerated activities taking place around the world. In fact, driven initially by government stimulus, investments by the electric power industry in IP technology is accelerating, with US$200 trillion projected in global expenditures by 2030.

In short, the networking piece of smart grid deployments is critical, as the migration of utility infrastructure to meet the needs to remotely monitor and manage their grids grows in complexity.  “The new IP/MPLS technologies offer a great deal of benefits within the utility in cost savings, operational efficiency and cost savings, and they also mandate a new way to operate, bridging those traditional organizational silos,” noted Mark Burke, VP of Intelligent Networks and Communications for DNV – GL, in a recent GridTalk posting.

IP/MPLS Enables Robust Public Safety Capabilities for Calgary

By Mae Kowalke, TMCnet Contributor

This is the third in a series of blogs that have taken a look at natural disaster communications and how public safety organizations around the world a leveraging next generation communications to better prepare and respond to emergencies.

In this final installment, the focus is on the Canadian city of Calgary which had catastrophic flooding in June. But it also got lucky.

That’s because just as the worst flooding in the history of the city was overflowing the riverbanks and flooding downtown, taking down infrastructure as it went, Calgary was testing its new, next-generation IP/MPLS-based network infrastructure.

As its infrastructure was endangered by the flooding, the city’s IT team was able to move over to this new system and start the migration of 50 remote locations in a matter of hours, preserving its essential communications needed to deal with the flooding and preserve business continuity.

Oil & Gas: Dynamic Communications Enables Faster, Farther and Safer Operations

By Mae Kowalke, TMCnet Contributor

The demand for oil and gas capabilities has never been greater and continues to grow. In fact, world energy needs are expected to increase by roughly 40 percent by 2030, according to the International Energy Agency, with the fast-developing China and India leading the way in energy consumption growth. The demand for oil is expected to grow by 20 percent, and gas needs should expand during this time by 50 percent. As much as dependency on fossil fuels is seen as needing to be reigned in, clearly oil and gas demand is going to go up despite greater reliance on alternatives. .

With that said, meeting energy needs is getting more complex. Hydrocarbon delivery is challenged by the fact that so much of the relatively low-hanging fruit has been plucked. The energy reserves of the future will increasingly come from deep-sea drilling, tar sands mining and other more challenging methods. Hydrocarbon delivery also will have to travel farther distances.

To effectuate cost-effective and efficient exploration and fuel deliveries in more challenging environments, it has become paramount that gas and oil communications be upgraded to next generation capabilities.

Railways See the Benefits of IP Convergence - Customer and Network Operator Perspectives

By Mae Kowalke, TMCnet Contributor

TDM just doesn’t cut it any longer when it comes to rail communications. Railway operations decision-makers the world over are moving from TDM-based rail solutions to a single IP-based communications network that maximizes bandwidth and delivery true multi-tenancy. When it comes to communications, rail solutions in 2013 are all about IP convergence.

“The necessity of an IP network transformation is due to the increasing need to host more services and its ability to converge these onto a single piece of infrastructure to provide a truly multi-service network,” Stefano Pasetti, director of mobile and telecommunications for Milan’s metro rail service provider, Azienda Trasporti Milanese (ATM), said recently in a blog post by Alcatel-Lucent.

MPLS-Based Networks Keep Public Safety Communications Humming

By Mae Kowalke, TMCnet Contributor

When it comes to first responder communications, network quality matters a lot. Public safety organizations need reliable, secure communications networks.

Traditionally, public safety networks have used plesiochronous digital hierarchy (PDH), synchronous digital hierarchy (SDH) or synchronous optical network (SONET) TDM technologies for their networks. But as communications have evolved, TDM is proving insufficient for IP-based voice, video and data systems.

“Many public safety communications networks are evolving to broadband solutions which utilize an IP WAN for first responder radio networks, video surveillance, LTE, improved interoperability, and better integration with growing IT applications, noted a recent white paper on the topic by Alcatel-Lucent, "Mission-Critical Communications Networks for Public Safety."

IP Convergence Delivers for Railway Operators

By Mae Kowalke, TMCnet Contributor

Rail communications have not been immune from the information technology revolution, but any new rail solutions need to be rock-solid since safety is on the line. Rail communications failure is just not an option.

Moving from separate network services to a converged IP/MPLS multi-service network is helping railway operations make a step-change in flexibility and efficiency while reducing total cost of ownership.

IP convergence--and IP/MPLS in particular—bring safety-related train control communications under a single unified architecture while delivering new railway communications flexibility.

One railway operations pioneer, Portugal’s REFER Telecom (the telecommunications subsidiary of Portuguese railway infrastructure manager, REFER E.P.E), has been using a fixed IP communications network since 2004. Since 2008 it has been running on IP/MPLS technology provided by Alcatel-Lucent.
