Software-defined networks aim to achieve high service quality, optimize resources, meet users’ expectations, and facilitate easy and optimal management.
Software-defined and automated computer networks offer many benefits, including increased network efficiency, reliability, and flexibility. A vital feature of the architecture is separating the data layer in the hardware from the control and automation layers.
The main benefits are:
- Efficiency and faster configuration. Automating network configuration and management reduces the need for manual effort, which means that new services, changes, or upgrades can be deployed faster. The software allows you to dynamically change network parameters according to your needs, such as automatically allocating network bandwidth according to the load.
- Reliability and reduced risk of errors. Manual network configuration is often subject to human error. Software management and automation mitigate these errors, as most processes are automated according to established rules and protocols.
- Network flexibility and responsiveness. Software-defined networks can adapt quickly to changing conditions and needs. For example, suppose a particular application or service requires more bandwidth. In that case, the network can automatically allocate more resources without human intervention, so the organization’s operations will not be disrupted and will continue to run efficiently.
- Optimization and resource efficiency. Automated networks can continuously analyze their health and performance and optimize resource use. This means better network bandwidth management, energy consumption, and other resources.
- Security. Automation enables faster detection and response to security incidents. Software-defined networks can automatically detect anomalies, block suspicious activity, send alerts about potential breaches, and identify how a security incident occurred.
- Lower operating costs. Automation reduces labor costs and operational costs by reducing the need for manual intervention and solving problems faster.
- Better infrastructure management. Centralized software management allows for better monitoring, analysis, and management of the entire network. This enables administrators to make informed decisions in real time and facilitates network expansion or reconfiguration. It is important to note that when network administrators change within an organization, it is much easier for new professionals to take over network administration.
