Network Optimization Overview

Many modern networks are highly complex with numerous interconnected devices, making it challenging to identify and resolve optimization issues. In addition, with ever-increasing demand for bandwidth and with emerging technology, optimizing the dynamic traffic can be more challenging.

Network Optimization use case in Paragon Automation enables you to optimize the utilization of network resources, enhance network performance, and ensure reliable and efficient delivery of data across the network. This is achieved by managing the life-cycle of label-switched paths (LSPs), also known as tunnels or segment routing policies, through an intent-based approach.

You create a path intent using the Paragon Automation GUI. Path intents provide you a way to define the connectivity you want to achieve and define how the controller should optimize the connectivity based on the real-time network conditions. Unlike traditional methods where each tunnel must be provisioned individually with all its attributes configured from scratch, path intent allows you to create and manage profiles that can be reused. This modular approach reduces redundant configurations and streamlines the process of provisioning connectivity using multiple tunnels.

The path intent consists of the following three sub-profiles:

• Tunnel profile—Defines specific properties of the LSP or segment routing policy.

• Optimization profile—Defines when the LSP or segment routing policy must be recomputed.

• Endpoints profile—Defines the endpoints and the topology of the connectivity between those endpoints.

When you apply the intent to the network, Paragon Automation interprets these intent-based profiles, automates the creation, modification, and deletion of LSPs or segment routing policies, by autonomously executing the necessary actions to align the network state with the specified intent. Paragon Automation ensures that LSPs or segment routing policies are established based on network policies and traffic engineering constraints to achieve the desired service level agreements (SLAs).

The Network Optimization use case relies on the network telemetry to have visibility and insight on link bandwidth, tunnel bandwidth utilization, and measured link delay across the network, and dynamically adjusts LSP paths to meet changing traffic patterns and demands.
