The Business Case for IP Transformation: Managing the Service Roadmap

By: Steve Blackshaw, IP Transformation Product Line Management, Alcatel-Lucent

IP Technology Programs are primarily focused on delivering technology solutions. However, the goal ultimately is to launch new services, and substitute old ones for all IP services. How do we ensure our technical visions deliver on these more marketing driven needs?

We need to ask… “Why Are We Building The Network?”

With IP Transformation programs sponsored and funded by the CTO, delivered by technology-focused teams, and culturally embedded within network operations, it is easy to forget that the over-riding objective of many programs is to actually change the service portfolio mix, for the benefit of both customers, and the provider.

So, how can Service Portfolio managers ensure that this vision is not lost when the programs are so heavily influenced by technology?

IPFIX Flow Direction and Packet Counters

July 8, 2015

In the world of NetFlow and IPFIX, flow direction is a topic that can confuse some of the best technical minds. It is an important concept in relation to routers because where information (e.g. byte counters) is gathered can have a significant impact on perceived accuracy.  This is sort of 3 part blog.  Although it isn't totally necessary, it might help the reader to understand a different type of flow directionality first as posted in my other blog.

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.
