Railways Can Meet Regulatory Needs and Boost Services with IP/MPLS

By: Mae Kowalke, TMCnet Contributor

While signaling and train control technologies have long existed to automatically trigger emergency brakes, railways are struggling to put them into place.

In North America, the Positive Train Control (PTC) system was mandated by the United States federal government in 2008 for railway lines carrying passengers and hazardous materials. Yet, the government deadline to have 96,500 km of track with the feature by 2015 will not be met.

Similarly, the European Train Control System (ETCS) in Europe, part of the Europe Rail Traffic Management System (ERTMS), is currently only deployed on 5000 km of track. The EU is aiming for a rollout on Europe’s 68,000km core network by 2030, and there is a long way still to go.

“With the US government set to introduce a five-year extension of the PTC bill by the end of 2015, and the EU turning the screw on ETCS deployment, this is not going away,” noted a recent blog post, Unlocking the benefits of train control with IP/MPLS, by Thierry Sens, Marketing Director Transportation Segment, Alcatel-Lucent. Sens, explained that, “Railways should therefore embrace the respective mandates as an opportunity to improve their network architecture and technology, specifically by introducing IP/MPLS.”

Large Enterprises: Think Like a Service Provider When it Comes to Network Connectivity

By: Mae Kowalke, TMCnet Contributor

There is hardly a business today that does not require high speed and high performance Internet connectivity. Let’s face it, quality network access is table stakes for running a successful business in an increasingly connected world where commerce is 24/7/365 and can originate or terminate from anywhere and over any device with a browser.  As a result, ensuring good networking and communications for employees is a major priority for all businesses, but it is an especially daunting one for large enterprises due the volume and the accommodation of rapid change thanks to things like the cloud, BYOD, mobility and the virtualization of the workplace.

A recent Alcatel-Lucent application note, The large enterprise has changed, gave an interesting snapshot of large enterprise IT today.

Virtual Residential Gateways Greatly Improve Route Reflection Resource Use

By: Mae Kowalke, TMCnet Contributor

There’s a strong case for virtual residential gateways, especially when it comes to route reflectors (RRs).

Border gateway protocol (BGP) route reflectors have long been an important network component, reducing the need for a full BGP mesh within an autonomous system. They often run on IP routers either dedicated to route reflection or performing that role in addition to IP routing and service functions.

The case for using a virtual residential gateway is a strong one when it comes to RRs. A dedicated RR is underutilized in the data plane because RR functions require minimal data-plane resources. Yet, routers that perform this role in addition to other jobs may not have enough resources in terms of CPU and memory.

New network service platform adds agility to cloud computing

Guest blog: Paul Parker-Johnson, leader of cloud and virtual system infrastructures practice at ACG Research

Alcatel-Lucent has developed its Network Services Platform (NSP) as a unified solution for creating agility in delivering network services. NSP brings efficiency and flexibility to the front-end problems of new service creation and the immediately downstream problems of operating those services efficiently and intelligently in a multilayer, multidomain, multivendor network. It does so in a unified and holistically designed solution.

Remarkable gains have been made in the cloud computing community to create and deploy new services efficiently and at scale. It’s also true that a significant impediment to service delivery is the rigidity of networks we deploy and processes used to define and instantiate services being offered.

A great deal of energy has been expended in recent years to enhance the flexibility of networks. Solutions have begun to appear that address parts of the problem, but to date they have been constrained to a particular function or domain and haven’t actually solved the whole agile service delivery problem for networks.

Until the Alcatel-Lucent NSP.

Not All Virtual Route Reflectors Are Created Equal

By: Mae Kowalke, TMCnet Contributor

Border gateway protocol (BGP) route reflectors have played an important role for decades, since they help remove the need for a full internal BGP mesh within an autonomous system.

Currently, most route reflectors run either on a router that is dedicated to route reflection, or on routers that also perform other IP routing and service functions. Both scenarios have downsides.

Dedicated BGP route reflectors are a waste because route reflection functions require minimal data plane resources. Routers that juggle route reflection with other duties, on the other hand, may not have sufficient resources to support scalable route reflection.

Alcatel-Lucent Explains the Importance of CDC-F Optical Networks

By: Paula Bernier, TMC Executive Editor

Today’s technology now allows a single fiber strand to carry up to 17.6 terabits per second of traffic. That’s the equivalent of transmitting 88 Blu-ray discs in a second. This ultra-broadband capability, and the new software-defined networks that service providers are embracing, have important impacts on optical networks further upstream.

“…we need to stay in the light/photonic domain as long as possible in order to reduce the cost associated with repeatedly converting wavelength photonic signals to electrical,” notes Scott Larrigan, senior marketing manager of IPR&T product and solution marketing at Alcatel-Lucent, in a recent TechZine posting, CDC-F optical networks propel us forward, and in the podcast embedded below.

vEPC in LTE networks: Time to move ahead

By: Keith Allan, Director IP Mobile Core Product Strategy, Alcatel-Lucent

From original TechZine article

Can the virtualized evolved packet core (vEPC) be deployed today in large scale, LTE networks?  Mobile network operators (MNOs) are increasingly convinced that the vEPC has become viable both financially and technically. And I think so, too, based upon the advances made over the past year that I’ll discuss in this blog.

Transportation communication networks: Combating the cyber terrorist threat

Talk of “cyber armies” working on behalf of nations might once have been the work of Hollywood, but recent events have demonstrated the opening of a new front in the global war on terror: cyber security.

On the Road to IP and Optics Convergence

By: Peter Bernstein, Senior Editor

For what seems like ages now the communications industry has been talking about convergence. We have already gone through many phases as networks move from TDM to being end-to-end Internet Protocol (IP) with voice traffic increasingly being carried on converged networks.  Indeed, the popularity of Voice-over-IP (VoIP) and the coming of Voice-over-LTE (VoLTE) on mobile networks is the future.  

That said, convergence is not just about IP but is also about the transformation of global network infrastructures in the wired world, with legs into the wireless one as well, of IP and Optics.  And, as Steve Vogelsang, VP Strategy and CTO, IP Routing and Transport Business Division, Alcatel-Lucent noted in a recent TechZine blog, IP and optics: Time to make nice, “Let’s face it. The future of the communications industry requires a convergence of IP and optics. So maybe it’s time to give each other some overdue respect."

The Need for Smart Cities is Obvious

By: Mae Kowalke, TMCnet Contributor

It goes without saying anymore that people and businesses in an increasingly connected world rely on the Internet for personal and commercial communication. We are also in the midst of a continuing migration of people are increasingly moving to cities as the world is becoming more urbanized.  What has also become clear is that cities with a smart grid and a solid IP infrastructure thrive more than cities that do not. The case for the smart city has never been stronger.
