the traditional network hardware was being replaced.For telecom operators
NFV was expected to deploy on the universal server
which could reduce the CAPEX and OPEX
improve operational efficiency
achieve rapid deployment of new service
and ultimately increase the operator's revenue.However
NFV had its unique characteristics
which would consume a large amount of public IPv4 addresses if we used the same deployment and configuration as traditional network hardware in the scenarios of enterprise PPPoE dial-up network.NAT444 was introduced in NFV environment as a solution
