CORD Design Notes

The following is a collection of architecture and engineering design notes that describe the CORD platform and various services built on that platform. It might help to start by understanding the Definition of CORD.

CORD Platform

Most platform-related components are now documented throughout the Guide. Additional information can be found in project-specific pages:

• Trellis - CORD Network Infrastructure.
  • The design of the CORD fabric, and the role of overlay virtualization in service composition.

• CORD Monitoring Service.
  • In-depth description of the CORD service to collect, archive and analyze real-time metrics.

• XOS and NEM
  
  • An architectural overview of XOS and how it is used to configure and control CORD services.

Residential CORD

• Virtual OLT (vOLT).
  • In-depth description of CORD's virtual OLT service.

• Virtual Subscriber Gateway (vSG).
  • In-depth description of CORD's virtual subscriber gateway service.

• Virtual Router (vRouter).
  • In-depth description of CORD's virtual router service.
