Companies, carriers, and other organisations are always subject to attacks from several directions. Cloud computing is at an all-time high, mobile usage is at an all-time high, and multimedia content is still growing exponentially.
Organizations are also under pressure to reduce their expenses without sacrificing revenue. The old business paradigm is seriously threatened when all these forces come together.
Several businesses are using SDN technology to modify the way they approach network monitoring operations and designs in an effort to adapt and become more efficient.
Using Software Defined Networking programmer that make use of open APIs in a centralized manner, SDN enables you to programmed network behavior. One can manage whole networks and their devices regardless of how complex the underlying network technology is when you open up the traditionally closed network platforms and build a central SDN control layer. Thus, the question of what software-defined networking is arises.
What exactly is SDN (Software Defined Networking)?
The concept of software-defined networking can be derived from SDN’s purpose. Software-defined networking as a result SDN is a network management technique. It accomplishes this by dividing the control plane from the forwarding plane. SDN is a strategy that, through network management, enhances network functions virtualization (NFV). Both do manage networks, but they do so in completely different ways.
You can view the network from a centralized point of view thanks to Software Defined networking. You will then be able to control the network as its brain. As a result, an SDN Controller can communicate with applications via northbound APIs and routers and switches via southbound APIs.
As a result, the centralised and programmable SDN environments can easily adapt to the needs of your organization as they change quickly. By limiting unnecessary provisioning, SDN increases network innovation and adaptability. This will help you cut your operating expenses.
The History of SDN
The first time the idea of SDN was realised was when Sun Microsystems introduced Java somewhere in the middle of the 1990s. Geoplex, an AT&T Labs project, was meant to be a service platform that handled online networks and services. It was referred to at the time as a “soft switch” that provided features like workload balancing and network traffic reconfiguration.
In an effort to create an object-oriented network operating system, a Sun Microsystems engineer founded WebSprocket in 1998. Due to this, VMServer and VMFoundry were introduced in 2000, paving the way for the creation of unique services that could be launched across a network. In 2001, Ericsson and WebSprocket collaborated to create the first soft switch that was marketed for sale. But it didn’t last very long.
Before the Open Networking Foundation was established in 2011 to support the usage of SDN, the idea was still being evaluated and developed. A standardized communications interface protocol called Open Flow was the one that was specifically being advocated.
The goal of SDN, or Software Defined Networking,
is to give businesses dependable but flexible SDN designs that can handle complex systems that combine cloud computing and internal infrastructure. SDN does this by modifying the underlying network infrastructure to divide network control from forwarding operations. As a result, network control may now be programmed and altered with the use of software. Greater agility is implied, and the network controller can dynamically modify the traffic flow throughout the network as necessary.
Software Defined Networking Advantages
- Due to the increased use of mobile devices over the past ten years, traffic patterns in businesses have experienced significant changes. This has prompted the migration of an increasing number of systems to the cloud. Ethernet switches, which once made it easier to implement the conventional and straightforward client-server designs, are no longer sufficient because a system with dynamic adaptability is required.
- As a result, one of the main benefits of Software Defined Networking marketing is how simple it makes it to use both private and public cloud services. As a result, your company can readily access these services and decide how, where, and when to use them. This enables easier and quicker resource scaling to adapt to any shifts in demand.
