With NFV and SDN, Telecom network will be reconstructed based on multi-tier data center has been considered by the industry as the evolution trend to achieve a scalability and flexibility when providing network service to different kind of customers. The architecture design of NFV is very important and will determine the scalability & extensibility of the network service provision in the multi-tier data center scenario also. In this presentation, Dr. Li Mo will share an experience of C/U separated and componentized NFV architecture design of gateway function like GGSN, SAEGW suitable for multi-tier data center. And how telecom Qos (such as inter data center reliability) is achieved in this multi-tier data center scenario.
