Understanding AR CORD: A Comprehensive Guide
Are you intrigued by the concept of AR CORD and want to delve deeper into its intricacies? Look no further! In this article, we will explore the various aspects of AR CORD, providing you with a detailed and multi-dimensional understanding of this innovative technology.
What is AR CORD?
AR CORD, which stands for “Central Office Re-Architected as a Data Center,” is an open-source edge computing project initiated by the Open Networking Foundation (ONF). It aims to transform traditional central offices into modern data centers, enabling efficient and scalable network infrastructure.
Key Terminology
Before diving into the details, let’s familiarize ourselves with some key terms associated with AR CORD:
| Term | Description |
|---|---|
| Full POD | A standard configuration used for testing AR CORD, consisting of three servers and four switches. |
| Collaborative POD | A single-node deployment of AR CORD. |
| CORD-in-a-Box (CiaB) | A virtual machine-based POD that can be used when physical servers and white-box switches are not available. |
| Development (Dev) Machine | A computer used for downloading source code, compiling it, and deploying AR CORD to a POD. It can be a server or a developer’s laptop. |
| Development (Dev) VM | A virtual machine provided by AR CORD that contains all the necessary software for installation and configuration. |
| Compute Node(s) | Servers in a POD that run virtual machines or containers, similar to compute nodes in OpenStack. |
| Head Node | A compute node in a POD that runs management services, including XOS (orchestration platform) and two ONOS instances. |
