Software Defined Networking or Software Defined Networking (SDN) has been considered by technology technology experts as the last word in the networking sector, but there is still a debate about the best way to implement it and which businesses it is suitable for. is suitable.
In fact, companies already realize the full potential that technology offers, and by implementing software-defined controls at the access layer, IT can centralize and unify network policies.
To further understanding of SDN technology and show why it is making a difference in difference in the management of companies' IT infrastructures, we've separated out some important points that should be taken into account when choosing a solution.
The evolution of SDN and its role in networks
Basically SDN technology is an architecture that aims to make networks agile and flexible. Its aim is to improve network control, allowing companies and service providers to respond quickly to changes in business requirements. requirements.
In a software-defined network, a network engineer or administrator can configure traffic from a centralized control console without having to touch individual switches on the network. switches on the network.
The SDN controller controller directs the switches to provide network services wherever they are needed, regardless of the specific connections between a server and devices.
This process is a departure from traditional network architecture, in which individual network devices devices make traffic decisions based on their configured routing tables. tables.
How it works in practice practice
SDN encompasses various types of technologies and functionalities, including functional separation, network virtualization and automation through programming.
Software-defined networking software-defined network uses a dynamic mode of operation, in which a switch issues a route request for a packet that does not have a specific route. This process is separate from standard routing, which issues routing requests through routers and algorithms based on the network topology, not through a controller. a controller.
The virtualization aspect of SDN comes into play through a virtual overlay, which is a logically separate network on top of the physical network. Users can implement end-to-end overlays to abstract the current architecture and segment network traffic.
This segmentation is especially useful for service providers and operators with cloud environments and services. environments and cloud services, as they can provision a separate virtual network with specific policies for each client.
Benefits that make the difference in managing companies' infrastructure
With SDN, an administrator can change the rules of any network switch when necessary, prioritizing or even needed, prioritizing or even blocking specific types of packets with a granular granular level of control and security.
This is especially useful in a multi-user cloud computing architecture, as it allows the administrator to administrator to manage traffic loads flexibly and more efficiently. efficient way.
Essentially, this allows administrator to use cheaper commodity switches and have more control over the flow of network traffic than ever before.
In addition, other benefits of software-defined networks are network management and end-to-end visibility. A network administrator only needs to deal centralized controller to distribute policies to the connected switches, instead of configuring connected switches, instead of configuring several individual devices.
This feature is also a security advantage because the controller can monitor traffic and implement security policies. If the controller considers the traffic suspicious, for example, it can redirect or drop the packets.
SDN also virtualizes the hardware and services that were previously run by dedicated hardware, resulting in the advertised benefits of a reduced footprint and lower operating costs.
Finally, software network contributed to the emergence of SD-WAN (Wide Area Network) technology. Area Network ). SD-WAN employs the virtual overlay aspect of SDN SDN technology, abstracting an organization's connectivity links across the entire WAN and creating a virtual network that can use whichever connection the controller deems controller deems appropriate to send traffic.
The impact of SDN on business strategy
Software-defined networking has had a major impact on IT infrastructure management and network design. network design.
As technology matures, it not only changes the design of the network infrastructure, but also infrastructure, but also changes the way IT sees its role, since technology management is more involved in the entire decision-making process and redefines the entire network infrastructure.
