This paper proposes the medium-long term vision where Telecommunications networks will evolve towards becoming Software Defined Infrastructures (SDI). In particular, SDI will be highly dynamic and pervasive environments of logical resources capable of executing any network and service function (e.g., from L2 to L7) developed and controlled as software applications. It is argued that SDI will be a...
This paper elaborates about the potential risks of systemic instabilities in future networks and proposes a methodology to control and mitigate them. The starting concept is modeling the network as a complex environment (e.g. ecosystem) of resources and associated controllers in a continuous and dynamic game of cooperation and competition. Key observation is that Internet might be viewed as “self-organizing”...
Over the next few years, we will witness radical changes in the way users consume communication services. Two of the most visible trends are the Over-The-Top (OTT) models, pushed by webcos, i.e. the major companies driving the offering of web services, and the telco model, favored by telecommunication network operators. Are they that different? With an analysis of the differences and the commonalities...
