Considering that audiovisual services will highly impact network architecture in the coming year, we check the impact of the traffic growth from several traffic evolution paths. Some optimization scenarios are proposed and compared looking at the Total Cost of Ownership and the network dimensioning. We show that depending on the context, flattening IP hierarchical network, bypassing transit routers for audiovisual services, and using caching server can help scaling the network and reducing the TCO.
