An intent-based network is fully abstracted from protocol and vendor, allowing the system to manage diverse hardware devices easily. This enables faster root-cause identification and remediation when network issues occur.
Automated Network Management
Intent based networking definition is an emerging networking paradigm that utilizes artificial intelligence (AI) and machine learning (ML) to automate and streamline network operations. It aims to revolutionize network management by enabling users to express their desired network behavior or outcomes (intent) rather than meticulously configuring individual devices and protocols.
As the name implies, intent-based networking relies on understanding business intent rather than network configuration. It takes high-level, unified business goals into operational objectives and outcomes. Then, it uses a combination of automation, centralized orchestration, and analytics to manage the network based on these objectives. It reduces manual effort, cuts errors, and reduces downtime, which are critical benefits of any automated system.
The software translates business intent into commands that the network infrastructure can understand. Then, the software ingests real-time network status to help mitigate resource contention and provide accurate configurations for different network functions. It also helps to identify and eliminate potential issues before they cause outages or other problems.
Finally, the network infrastructure applies these configured changes to the underlying network. The result is a more agile and responsive network that aligns with the original business intent.
Intent-based network management slashes time spent on manual tasks, such as pushing configuration changes to hundreds or thousands of devices. It also ensures consistency and accuracy of configurations across the entire network. Additionally, the technology offers visibility into the network and quickly identifies the root causes of performance issues, reducing downtime for critical applications. Intent-based network management can prevent security breaches by detecting abnormal traffic and rerouting it over more secure networks.
Enhanced Security
Intent-based networking uses machine learning to identify network issues and automatically adjust policies in real-time. It improves performance and reduces downtime, increasing business agility. Additionally, it helps prevent security breaches by detecting and reacting to potential threats in real-time.
Intent-based networks ingest diagnostic information from Layer 3 routers, SD-WAN appliances like Viptela SD-WAN, and other network infrastructure devices. They can also consume information from a monitoring system and network telemetry to track application performance over various links. This data helps the intent-based network detect and resolve problems before they impact end-users, reducing the risk of downtime, lost productivity, and revenue loss.
An intent-based network aims to automate network operations and implement security and prioritization policies. It also performs self-checks to ensure it operates as intended and achieves its goals.
Network administrators can define their intent in plain language or via a graphical interface, and the software will translate and deploy that intent to network infrastructure, device by device. It removes the need to update network configurations manually and device by machine with a command-line interface (CLI). Intent-based networking offers several cost-saving benefits for IT teams, including reduced labor costs, lower hardware and energy expenses, and fewer manual mistakes. This allows organizations to focus their budget on more strategic projects that help achieve their goals.
Scalability
The ability to scale network services quickly is a vital business imperative. IT teams must be able to respond to shifting customer demands, such as the need for more bandwidth to support new applications or the need to expand Wi-Fi coverage for a large event while keeping existing resources safe from cyberattacks. Intent-based networking makes this possible by enabling the network to translate business objectives into network policies and configurations automatically.
This translates into a process that allows network managers to describe the desired outcomes without specifying how those objectives would be achieved, allowing for more agility and faster resolution of problems when they arise. The system then identifies the best path to achieve these goals by translating them into a network configuration and design that can be implemented on the network infrastructure. This automated process can ingest real-time network data, validate the intent, and execute changes automatically using machine learning.
It reduces the number of manual steps required for network deployment, slashing time and effort. Furthermore, it provides more robust security through the validation of every policy. It ensures that only the correct configuration will be deployed and limits the scope of change, reducing potential issues during the deployment phase. Intent-based systems also monitor the network to detect possible deviations from the desired state and take action to correct them.
Analytics
The software that runs intent-based networking analyzes data about how your network is operating and what it is doing. That data is used to identify issues and then to automate correcting them. It eliminates manual intervention, meaning you can solve problems more quickly. It also allows you to improve your network performance, enhance security, and reduce costs.
This system provides analytics that can detect and fix misconfigurations, reducing server downtime. It also helps prevent security breaches by monitoring network behavior and looking for vulnerabilities, even in encrypted traffic. IBN can also help you meet your business goals faster by identifying issues and reacting to them immediately, rather than waiting for an incident to occur and attempting to resolve the problem.
Intent-based networking systems can help you automate your network management, allowing you to focus on your business. These systems use a combination of processes like telemetry, automation, translation and validation, and network state awareness to manage devices most effectively.
Intent-based networking is one of the most promising technology trends in the industry, and it offers a wide variety of benefits for businesses of all sizes. These benefits include better access control, massive scalability, enhanced security, and the ability to manage multi-vendor devices.
With these advantages, IBN can help you optimize your network and make it more efficient and scalable.
