VoWiFi extends and enriches LTE services

By: David E. Nowoswiat, Senior Product and Solutions Marketing Manager, IP Routing & Transport, and  Ed Elkin, Head of Marketing for IP Communication, Alcatel-Lucent

The growing importance and usage of Wi-Fi™ is spurring rapid development in voice over Wi-Fi (VoWiFi) to complement robust VoLTE services. Mobile device manufacturers are taking advantage of Wi-Fi to solidify their relationship with consumers and enterprises, so mobile network operators (MNOs) need to act quickly to secure a share in the hot Wi-Fi market. By developing a strategy that encompasses Wi-Fi, MNOs can leverage their most important asset - their LTE network - to deliver a seamless experience for subscribers while leveraging their virtualized IMS investment to create  new revenue opportunities for themselves.

Mobile World Congress 2015 - What's the Next Big Thing?

By: Peter Bernstein, Senior Editor

In doing preparations for what many have called “the circus” aka the annual Mobile World Congress (MWC)—which is arguably now the most important industry trade event as the world goes mobile and which takes place in Barcelona March 2-5—the excitement is already palpable.  From all of the new cool devices of all shapes and sizes to interesting advances on things like antenna technology, Network Functions Virtualization, carrier aggregation, etc., the eye candy alone is almost overwhelming in terms of imagining the possibilities.  However, MWC always is tantalizing because not only does it answer what we will see in terms of capabilities in the near-term, but also because of the questions it raises about the longer term.

In this regard I was struck by a recent blog by Michael Peeters, CTO, Alcatel-Lucent Wireless, entitled I think appropriately, The Circus is in Town. Peeters’ main point is summed up nicely where he says in characterizing his view on what’s the next big thing that will be the buzz of the show that, “...one thing is certain: its story will be about removing place and time constraints we took for granted.”

NetFlow Calculator for Supermen!

June 4, 2014

When sizing a NetFlow or IPFIX collection appliance, many consumers go looking for a NetFlow calculator.  In order to do some calculations, you'll need to have some numbers handy. For example, what volume of flows per second can all of the hardware combined generate?  This is an important question because it will likely influence the type of collector your team invests in.

A software based collector should be able to scale to well over 40,000 flows per second which is over a couple million flows per minute.  A hardware based solution should scale to well over 100,000 flows per second.  If the solution can be distributed, collection rates well into the multi millions, should be attainable.  The problem that customers need to be aware of is that flow volume is not always directly related to bandwidth consumed.
