IP Routing and Transport

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.

Railway Operators Moving to IP/MPLS for many Good Reasons

By:  Mae Kowalke, TMCnet Contributor

As greater demand is being placed on Railway operators to deliver services that are more bandwidth hungry, many are starting to make the switch away from the SONET/SDH architectures that have traditional run their communications network and move toward the more robust IP/MPLS architecture. In fact, Europe is illustrative of this with rail transportation systems in Milan, Paris and Portugal already enjoying the operational and customer experience benefits of making the move.

There are many reasons why railways are using IP/MPLS for their communications networks but two major ones are:

  1. IP/MPLS offers high network availability and resiliency through “Non-Stop” technologies such as Non-Stop Routing (NSR), Non-Stop Services (NSS), Link Aggregation Group (LAG) and Fast ReRoute (FRR).
  2. IP/MPLS enables traffic engineering and isolation, since railway communications cannot afford to fail.

Columbian Broadband Provider Brings 100G Rollout in Time for World Cup Action

By Mae Kowalke, TMCnet Contributor

Anyone who knows “futbol” (aka “soccer” in the U.S. and “football” elsewhere) knows how enormously popular it is in Latin America.  Hence, being able to provide as many fans as possible great inside and particularly remote from stadium user experiences has become something of an obsession.  Illustrative of this is that thanks to its newly installed 100G ultra-broadband network, Colombia’s mobile provider, UNE, was able to debut widespread streaming video services in time for the recent 2014 FIFA World Cup. This meant its subscribers could have quality viewing experiences over their   smart TVs, tablets and smartphones.

Why Carriers Are Embracing NFV, and What They Should Demand of These New, More Agile Environments

By: Paula Bernier, Executive Editor, TMC

Service providers are undergoing a sea change.

Their networks, which traditionally have been based on turnkey network elements running software on purpose-built hardware, are moving to a software-centric model. In this model the true value lies in the software, while the hardware is typically of the commercial-off-the-shelf variety.

Network Functions Virtualization (NFV) is the name of this new architecture, which not only embraces the model of instituting network functionality in software and running it on industry-servers, but also allows applications and services to leverage those resources whenever and wherever they are.

Partnering to Meet the Challenges and Opportunities in Building Smart Cities

The dynamics of this global change are fairly well known, although how to address the challenges isn’t so obvious. For example, cities consume three quarters of energy and contribute 80 percent of CO2 emissions globally, according to a recent report in The Guardian. How can that energy be most effciently delivered, with minimal environmental impact?

Consensus is emerging that what’s needed are smarter, safer, greener cities. Governments and municipalities are under pressure to invest in sustainable infrastructure capable of efficiently delivering services to citizens and workers.

There’s a pretty compelling smart grid transformation opportunity for public-private partnerships embedded in this evolution. Together, telecom service providers and information and communication technology (ICT) providers can bring in their assets, expertise and experience to help power utilities meet goals for smart grid applications.

German Internet Exchange Shows its Support for Alcatel-Lucent's IP Core Routing Solution

By: Mae Kowalke, TMCnet Contributor

The routers and infrastructure that lay at the foundation of Internet service provider (ISP) networks rarely are named; which service routers that ISPs use are not often openly discussed.

But sometimes the veil does get pulled back, as was the case recently with the announcement that the world’s largest ISP, Germany’s DE-CIX, has leveraged the Alcatel-Lucent 7950 XRS Extensible Routing System (XRS) for its newly deployed DE-CIX Apollon German Internet exchange.

Successful Communications Services Have Six Features in Common

By: Mae Kowalke, TMCnet Contributor

Large enterprises increasingly resemble public network service providers as they manage access, transport and network routing while controlling devices and sessions. Whether businesses build their own or buy their communications services through a public provider, the IP communications architectures are looking remarkably similar.

“I’ve noticed that both private service operators (CIOs of large enterprises) and public service providers are implementing very similar solutions around the globe,” wrote Oliver Krahn in a recent TechZine article, 6 Steps that Improve Communications Services.

Cable MSOs Can Learn a Lesson from Kabel Deutschland

By: Mae Kowalke, TMCnet Contributor

Kabel Deutschland (KD), a Vodafone company, is a good example of what cable multiple system operators must do to gracefully manage growing demand and continue to deliver innovative new services by upgrading their network edge for IP services.

As highlighted in a recent TechZine article by Steve Davidson, European Marketing Director for Cable, Alcatel-Lucent, KD’s investment in infrastructure and cable services had already paid great dividends. The company’s initial 100 Mb/s product offering had a take-rate approaching 50 percent. But with this positive consumer response came some new challenges.

Among these challenges were managing cable operator costs and subscriber growth, supporting legacy cable services, and accelerating IP service deployment. How the cable company dealt with these problems and did so in the context of having a vision of its IP services future is worth studying.

Ethernet VPN Brings Distinct Advantages over Its Predecessor

By: Mae Kowalke, TMCnet Contributor

Ethernet services delivery based on the control plane approach hasn’t changed for proven solutions such as MPLS/VPLS and PBB. Layer 2 flooding and learning as an approach to build the forwarding database is still necessary, but this has inherent limitations.

A new approach has emerged that brings many benefits over the control plane approach in the form of Ethernet VPN (EVPN). With EVPN, the control plane and data planes are abstracted and separated. A multiprotocol BGP (MP-BGP) control plane protocol carries MAC/IP routing information, and there are several data plane encapsulation choices.

Enterprise Service Gateways Help Operators Extend Their Mobile VPN Offerings

By: Mae Kowalke, TMCnet Contributor

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).
