The emergence of cloud computing and mobility, not to mention bring-your-own-device trend (BYOD), has introduced a strong need for mobile virtual private networks (VPNs). Yet, most operators are only able to offer mobile VPNs to larger customers since their fixed-line VPN infrastructure is often separate from their cellular infrastructure.
One solution to this problem, outlined in a recent TechZine article, Mobile VPNs for Enterprises of All Sizes, by Jan Vandehoudt, Principal Consulting Engineer and Patrick McCabe, Senior Product Marketing Manager, Alcatel-Lucent, is for mobile network operators to use an enterprise services gateway (ESG).

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.
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.
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.”

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.

Skyrocketing energy demands and the push for greener, more sustainable energy solutions has helped bring smart grids to prominence, and has encourage a number of utilities to deploy a next-generation network alongside their electrical grid.
AltaLink, one of Canada's largest electricity transmission providers, is one of the utilities that is currently undergoing the complex, yet highly advantageous transition from a TDM architecture to a next-generation IP-based network.

Ever-increasing energy consumption, skyrocketing operating costs and pressure from regulatory bodies to help create a greener world have forced power utilities to reassess their delivery management methods.
The need for change – along with the recent influx of innovative network technologies – has led many utilities and distribution and system operators (TDSOs) to embrace the smart grid, a concept aimed at leveraging the power of next-generation networks to improve the efficiency and reliability of energy delivery and usage. The visibility and control provided by the smart grid enables utilities to match supply and demand, optimize delivery, cut operating costs and reduce carbon emissions.
In addition, a smart grid opens up a two-way communication system between utilities and customers, thus creating additional upsell opportunities and the ability for consumers to take a hands-on approach to energy conservation. Smart grid customers have access to their own webpage that details their energy consumption and the associated costs.
Deploying a smart energy grid is vital for utilities to thrive in the current environment, but it doesn't come without complications. TDSOs need to chose the appropriate technologies, understand their network requirements and make major decisions like if they should build their own communications infrastructure or lease it from a service provider.
Many of these questions can be answered by Alcatel-Lucent, whose Integrated Communications for Power Utilities solution is a proven way to take utilities into the 21st century of energy delivery and efficiency.
With its experience designing and deploying IP and LTE broadband wireless access networks, Alcatel-Lucent has a unique perspective on what is needed to get a smart grid initiative up and running.
