With the remaining IPv4 address becoming more and more scattered, it is complicated to manually configure the address pools on lots of Broadband Network Gateways(BNGs) for operators. By introducing SDN/NFV in BNG, the address pools can be allocated in a centralized way. It will not only simplify the address management for operators, but also improve the utilization efficiency of the address pool.
