When networks used to be static and permanent, updating them or rolling out new services took much time and effort.
The advent of SDN and NFV, however, made networks flexible and responsive, and most importantly decreased the cost associated with them – both operational and capital expenses. Adding features and applications became fast and transparent.
Today, providers are deploying a dynamic infrastructure and think networks from the application side.
The most significant driver to this trend in today’s communication networks is the unification of telecommunication and IT worlds. BISDN facilitates this trend with new management, orchestration and security concepts for the network. This will bring forward new opportunities for using future networks.
