System architecture

Highlights of DANOS-Vyatta edition

The NOS architecture is designed for abstractions with clean APIs between the layers for development agility, troubleshooting and ease of supporting multiple white boxes.

The application layer encompasses all the routing and supporting processes along with the standard APIs and familiar CLI interface for operators and management, automation, orchestration systems to interact with the NOS. The application layer interfaces with the system infrastructure layer, again via modular interfaces. DANOS-Vyatta edition uses standard Linux at its core and this is part of the infrastructure layer as well. Use of Linux comes with all the well-known scripting, tooling capabilities.

The forwarding layer’s main role is to interface with the infrastructure layer above for data necessary for forwarding and other functions in a modular way as well as support abstractions necessary to enable easy of ODM integration. The Forwarding Abstraction Layer is the key module that enables rapid qualification of ODMs.
