Key Questions Answered
What is Open/R and how does it enhance network applications?
Open/R is a modular and extensible distributed network application platform designed by Facebook to improve the speed, efficiency, and quality of internet connectivity. It allows for rapid prototyping and deployment of network applications, originally developed to support the Terragraph wireless network.
How does Open/R achieve rapid deployment compared to traditional methods?
Open/R enables faster deployment by allowing Facebook to control its network entirely, avoiding the lengthy interoperability processes required by multiple vendors. This allows for a focus on essential features and quick iterations, enhancing overall network performance.
What are the key components of the Open/R architecture?
The key components of Open/R include the KV-STORE for state management, LINK MONITOR for detecting link changes, the DECISION module for routing calculations, and the FIB for interacting with routing hardware. These components work together to ensure efficient routing and quick failure recovery.
How does Open/R ensure reliability while allowing rapid updates?
Open/R maintains reliability through a combination of network design, operational practices, and quick code deployment. It segments networks into partitions to isolate failures and implements rapid failure detection, allowing for efficient updates without compromising system stability.
