We’ve just published a new whitepaper for premium Ignition members: Intent-Based Networking 2: A Deep Dive Into Network Abstraction & Continuous Validation.
As a follow-up to our introductory whitepaper on Intent Based Networing (IBN), this piece goes deeper on the fundamental technologies that drive IBN.
Written by Phil Gervasi, the paper includes the following:
- 19 pages
- Explores in greater technical detail how Intent-Based Networking (IBN) systems work
- Explains how IBN systems abstract network devices & configurations to build working models
- Discusses the pros and cons of different approaches to abstraction
- Reviews the closed-loop model that drives the value of IBN systems
- Provides key takeaways
From the Introduction:
Intent-based networking (IBN) is a fundamental shift in network operations and not simply a new platform to buy. Its focus is network operations; that is, the configuration of network resources to meet a business requirement.
As networks scale, network operations become difficult, inefficient, and error-prone. IBN aims to solve these problems through closed-loop automation and orchestration.
IBN uses a continuous integration/continuous delivery model that automates tasks and continuously validates the network. Using this model, a network can be discovered, compared to benchmarks of desired outcomes, and corrected manually or via automation if discrepancies exist.
This approach differs markedly from typical network operations; that is, device-by-device management with a focus on micro configurations and physical devices, without seeing the entire infrastructure as a whole.
IBN is not a new protocol; it is the confluence of well-known technologies linked by an operational workflow.
IBN focuses on three main areas:
- Network Abstraction
- Continuous Validation
- Autonomous Remediation
This paper explores each of these areas.
