Ratio between deplyed vE-CPE and Residential GW might reach 1:100 or even 1:1000, thus VNF management overhead must be minimized. For instance, self-termination after predefined activity period seems preferable over explicit VNF removing via management system. -#. Distributed Base station. +4. Distributed Base station. TBD.
