Traditional network frameworks have been built over decades, which is hard to change overnight. Luckily, with SDN and NFV, the flexible and cost-saving framework simplifies deployment, setup, and maintenance, which help telcos build customer-centric business models.
"Dedicated hardware like routers, switches, and servers in telco facilities serve for fixed duties. Rigid frameworks make it hard to design and configure, let along catering to customer needs. However, SDN and NFV bring elasticity to the telecom industry," said Hadwin Liu, Chief Architect of NEXCOM Network and Communication Solutions Business Group.
NFV incorporates multiple servers as a big virtual one in telecom facilities. Using resource management platform like OpenStack, telcos can view hardware resources and set rules based on service demands to provision computing, storage, or bandwidth resources automatically.
NFV quickens application deployment like load balancing, QoS, and eMBMS. Under this framework, the next generation CPE with computing capability serves as a node in telco facilities, allowing telcos to reallocate nodes' resources and to offer security services like VPN, firewall, and UTM with less capital investments and less time to market.
Programmable network frameworks facilitate operation and maintenance. SDN adopts software to define network forwarding rules. With pre-defined algorithms, software dynamically changes how network traffic is forwarded while automating the deployment, configuration, and management of networks.
NEXCOM's communication platform supports open-source software for SDN and NFV implementation, helping telcos integrate server resources, coordinate network functionality, apply centralized control, and dynamically adjust network performance to enhance competitiveness with customer-centric services, applications and low TCO.
