The term network discovery or network visibility describes the process by which a network discovers other networks and how they discover each other. Network discovery is critical to the operation of a large, distributed system.
Without network discovery, networks do not know each other nor do they have access to shared resources. With the introduction of the Internet Protocol (IP) and its routability, there has been considerable interest in developing an IP protocol that can be used for infrastructure-level networking.
The latest development in this area is called infrastructure-based networking (NFV). NFMV is a generic term that refers to all kinds of new protocols and implementations that replace or supplement IP for distributing applications, content, and routing information within a system.

What is the relationship between SDN and NFV?
Networking is a process that connects devices and systems in a system. This system can be a network, device, or application.
When networks connect devices together, applications communicate with each other and the external world. When devices communicate with each other, applications access the external world via the network.
NFV relies heavily on advanced technology such as automation and orchestration to function correctly.SDN relies on lower level technology such as flow control to function correctly.
NFV has increased significantly in popularity over the past year due to its decreased need for human intervention. Increased automation will reduce human errors which increases your bottom line!
Whether you are looking into SDN or NFV, there are some basic terms that should be understood. This article will discuss those terms again!.
How can SDN and NFV help my business?
Networking technology such as the internet, phone, and computer network are often referred to as the ‘system’ in which a business operates. As the central hub that connects all of your internal systems, your business is essentially operating on multiple networked computers, phones, and phones connected to the internet.
This system can be beneficial for a business, allowing it to expand its reach without investing significant funding. For example, a company that sells wholesale electronics products could use a high-speed internet connection,VOIP (internet-based voice processing), and NFV (network function virtualization) servers in order to grow its customer base.
NFV allows for software to communicate with hardware in order to scale up or down their functionality. This is accomplished by utilizing virtual machines (VM’s), which are computer simulations of another system. These VM’s can be used to add new functionality or scale down older functionality.
What are the concerns with SDN and NFV?
As the internet of things (IoT) continues to grow, more and more devices will need to be connected. By being able to manage all of these devices in one place, intelligently, and helping save energy is a big concern.
SDRs offer a hopeful solution to this as they can pre-plan connections and put them in motion without always using the highest speed connection. By having multiple connections pre-planned, savings can be made in electricity usage.
NFV offers the chance to build new services and products on top of existing ones.
Who is using SDN and NFV?
Today, everyone from large enterprises to medium sized businesses are looking into SDN and NFV. There are many benefits to adopting SDN and NFV, including cost savings, increased efficiency, and faster innovation.
Now that smartphones have become common devices, users constantly have access to new applications and features. This app accessibility makes it very attractive to developers as a platform.
With smartphones having more than one account, apps need a way to be secured. Carrier services such as LTE or Wi-Fi connectivity needs secure communication between apps and the system to prevent unauthorized users from accessing personal data.
App adoption has increased notably since both platforms were introduced. Developers now have two places to develop their apps which are on the same platform!
In conclusion, both NFV & SDN bring benefits to app development and application uptake has gone up since these new platforms came into play.
What is the relationship between SDN and NFV?
In order to understand the differences between SDN and NFV, it is important to know the function of both technologies.
NFV aims to deliver an applications-first, platform-second environment for IT. As a result, applications can be deployed in any location, as they are served by a cloud computing platform.
As part of NFV, components calledacks or networks are used. These networks may be internal or external, connected via routers and/or switches. They may be private or public, since they serve only certain entities.
SDN aims to create an environment in which everything is connected and everything learns from its surroundings. By doing this, everything becomes smarter and better at delivering services.
To fully understand the difference between SDN and NFV, it is crucial to understand the differences between these technologies.
How can I start using SDN and/or NFV?
Today, we will talk about some of the ways you can use SDN and/or NFV and start using them in your organisations. If you are already using these technologies, then this article will also talk about how to best apply them to your organisation.
SDN and/or NFV bring new technologies into your organisation and allows new technologies to be integrated into your current systems. This is very useful as you can create new applications, applications can be installed on virtually anything, making it very convenient to take advantage of these newer technologies.
Your employees can either learn the new technology or implement it on their own if they are not familiar with SDN and/or NFV. This can be a helpful way to keep everyone updated on what is going on in the organisation!
Since these newer technologies work at the network level, they can integrate well with other software components.
What are the benefits of using SDN and/or NFV?
Today, wireless networks are a permanent part of our everyday lives. We have them at home, at work, and in our mobile devices. They keep us connected wherever we go!
Network technology has nearly limitless applications. Some of these applications include serverless computing, real-time app delivery, and distributed computing. With the introduction of SDN and/or NFV, additional benefits can be gained such as optimization of application delivery or orchestrating multiple network traffic analyses.
When used correctly, SDN and/or NFV can save bandwidth and increase application efficiency. Although there are many benefits associated with using network technology for applications and infrastructure, the most important benefit associated with mobile applications is user mobility.
Mobile users are constantly on the move. They need a reliable connection to stay in touch with their colleagues or update their work product. By using SDN and/or NFV on moving platforms, thermal stress is eliminated which reduces power consumption over time.
What are the drawbacks of using SDN and/or NFV?
Both technologies have their benefits, and their biggest drawbacks. For example, SDN costs more than NFV does!
Although both technologyologies have the same goal of bandwidth management, NFV is a little more complex to deploy. As a result, fewer networks are implemented with it than SDN.
NFV is also easier to deploy with fewer people involved due to the complexity of the solutions. Many people are intimidated by the technology and how it’s deployed.
