RTOn
RTOn, or Real-Time Optical Network, is a term used to describe an approach to optical networking that prioritizes deterministic, ultra-low latency data delivery across wide-area and metro networks. In RTOn designs, the objective is to provide bounded end-to-end latency and predictable performance to support time-sensitive applications.
Key characteristics include deterministic latency and jitter bounds, guaranteed bandwidth for critical flows, high-precision time synchronization,
Typical architectures combine DWDM optical transport with control layers that may rely on SDN, along with time-sensitive
Status and standards: RTOn is an emerging concept rather than a single standardized technology. Research prototypes
Applications and challenges: RTOn is seen as enabling industrial automation, real-time data analytics, virtual reality streaming,
