Want more from IP networks? Management’s the key
May 13, 2011 by Massimo Enrico in the theme A new generation of IP Networking
When I talk with colleagues and customers about the new generation of IP networking, there is one word that is used very frequently: "more."
When "more" relates to bandwidth, services, capacity, scale and quality of experience, everybody wants to hear it. Everybody likes the great business and social opportunities that we can foresee in the years ahead. But there is less enthusiasm when "more" is associated with complexity, cost, time for provisioning the network, and increases in overall operational cost driven by the type of services, number of connections and size of the network.
The key to handling the trade-off between positive and negative here is network management, the software that operates the network.
After working for many years in the telecom world, I know that network management is the big challenge for transforming network expectations and promises into reality. We are going to face the same experience we had several years ago in computers: where we once used to speak of CPU speed and RAM capacity, we gradually shifted the discussion to operating systems and finally tools and services. The scope, the service, is becoming king. This concept is now so important that we have entered the cloud era where the means – whether hardware or software – simply disappear.
Similarly, in the telecom world, the network – converged, with a lot of capacity and growing quickly – is becoming a given, just like the x86 platform in the computing world. The question is how to exploit this potential efficiently. To achieve that, we need to rethink network management, similarly to the shift that happened in the move from DOS to Windows and finally to iOS and Android. We will look more closely at that in my next entry.
