Conclusion
In recognition of the benefits accruing from the deployment of NGNs, many countries have embraced the drive to promote convergence and growth in data networks. NGNs reflect convergence of networks. The NGN enables users from the mobile telephony network, the fixed telephony network and the broadband network to connect to one common network. This makes it possible to create one shared environment where all types of communication services are deployed.
Rollout of NGNs achieves its full potential with the rollout of broadband networks and in the development of data communications. Furthermore the UN Broadband Commission in 2011 set a number of global objectives including making broadband policy universal and making broadband financially affordable. It is thus expected that by 2015, all countries should have a national broadband plan or strategy to integrate broadband in their definitions on access and universal service.
