What is Network Architecture?
Network architecture is the design of a network’s physical and logical components, including its topology, communication protocols, hardware, software, services, and security features. It ensures efficient, secure, and reliable communication across organizational systems.
Why Network Architecture
Efficiency and Performance
Proper network architecture ensures that data flows optimally across the network, reducing bottlenecks, minimizing latency, and maximizing bandwidth utilization. This leads to improved performance and faster response times.
Reliability
A robust network architecture enhances the stability and uptime of network services. Redundancy, failover systems, and other design considerations help ensure continuous service availability even during failures.
Security
With the inclusion of comprehensive security measures, network architecture helps protect data integrity and confidentiality, prevents unauthorized access, and ensures compliance with relevant security standards and regulations.
Manageability
A thoughtfully architected network simplifies management and monitoring, making it easier to identify and resolve issues, manage upgrades, and maintain overall network health.
Components of modern network architectures
Intent-based Networking (IBN)
An intent-based network takes an organization’s desired outcomes at a high level as input and sets up the network to achieve these objectives. It does so by automating operations extensively, analyzing network performance, pinpointing problematic areas, providing all-around security, and integrating with business processes.
Controller-led
Network controllers are foundational to intent-based networking and are essential to scaling and securing networks in the digital era. Controllers dramatically simplify operations and help organizations respond rapidly to changing business requirements. They automate networking functions by translating business intent into device configurations, and they monitor the network devices continuously to help ensure performance and security.
Multidomain
Multiple networks in an enterprise communicate with one another through their controllers. Such cross-network, or multidomain, integrations generally involve exchanging relevant operating parameters to help ensure that desired business outcomes that span networking domains are achieved
