There are some confusions surrounding the differences between SDN and NFV. Both terms relate to virtualization of network; both are hot topics these days. Sometimes, one concept is mixed with the other.<\/p>\n
SDN stands for Software Defined Network. It is based on\u00a0 two pillars.<\/p>\n
SDN concepts<\/a> came into being while researchers were frustrated with changing \u00a0\u00a0software in network elements every time they wanted to try something new to study behavior in network. They thought, why not program the network elements and manage them from central place. The language that brings this programmability to network is called \u201cOpen flow\u201d.<\/p>\n NFV ( Network Functions Virtualization) \u00a0on the other hand is about virtualizing network elements by using \u00a0commodity servers so as to reduce operator\u2019s inventory, power and space requirements and hence reduce CAPEX and OPEX.NFV is driven by operators and the concepts were put forward originally by a group of service providers through a white paper.<\/p>\n So what is the difference between the two?<\/p>\n It is commonly understood that Both SDN and NFV are totally independent from each other. This is partially true. Especially, when SDN concepts are taken, they do draw relevance from NFV. While separating control and forwarding functions and programmability are core concepts in SDN; these cannot\u00a0 be achieved unless network elements become commoditized and their functions virtualized- the core concept of NFV<\/a>. However it can be said that NFV can exist without depending on SDN; however, even though\u00a0 network elements are commoditized but still network will not be efficient if there is no network programmability as desired in SDN. Therefore SDN and NFV help each other and if implemented together can make the network flexible, virtual and commoditized.<\/p>\n","protected":false},"excerpt":{"rendered":" There are some confusions surrounding the differences between SDN and NFV.
