SDN, NFV & Cloud Computing

Re-Defined The Network Framework Nowadays


SDN has re-defined the network framework nowadays, SDN comes from the IT world, which separates the data and control layers while centralizing the control.

SDN delivers the ability to program network behavior using well-defined interfaces. On the other hand, NFV was born to meet Service Provider (SP) needs and shape the new network equipment architecture. It minimizes CAPEX by reducing/ eliminating proprietary hardware and consolidate multiple network functions onto industry standard platforms. Below figure shows the relationship of SDN, NFV and Cloud.

SDN/NFV Technical Requirements

– Manageability
– Interoperability & Compatibility
– Reliability & Stability
– Security
– Performance

NFV Application: VCPE

Virtual CPE becomes the future for the telecom market due to the lower opex/capex, the concept is based on NFV application, which virtualizes the original function of CPE and provides the service depending on customer usage.
