The role of SDN and NFV for dynamic bandwidth allocation and QoE adaptation of video applications in home networks

Software Defined Networks (SDN) offers the opportunity to drive down costs through increased operational efficiency-network utilization in particular-service creation velocity, and differentiated and personalized network services. This way the CAPEX and OPEX costs for the operator are going to be drawn down and same way costs will be drawn down for the end user. In the context of UNIFY project [1], one of the main objectives is to focus on enablers of such unified production environment and will develop an automated, dynamic service creation platform, leveraging a fine-granular service chaining architecture.
