Solution Overview
Problem
Conventional techniques fail to optimally control an optical transport network automatically based on communication requirements from geographically dispersed computers, necessitating manual operation and lacking integration with upper-layer computers.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual operation is used to grasp and control optical transport path state, then control flexibility is maintained, but automation level and operational efficiency deteriorate
Solution Approach 1:
The optical transport network performs self-monitoring and self-reporting of its state through measurement units at each node that automatically detect and communicate path conditions to the orchestrator, eliminating the need for manual state assessment and enabling automated control decisions
Solution Approach 2:
The orchestrator acts as an intermediary between upper-layer computers and lower-layer optical network devices, receiving communication requirements from computers, determining optimal optical paths, calculating setting information, and automatically configuring network devices without manual intervention
2Extent of automation
If integration with upper-layer computers is implemented, then automatic control capability improves, but system complexity increases
Solution Approach 1:
The orchestrator provides universal control functionality by managing multiple optical network devices and handling various communication requirements from different computers through a unified interface, reducing the need for separate control systems for each device or computer
Solution Approach 2:
The system is segmented into distinct functional layers: upper-layer computers that generate communication requirements, the orchestrator that performs path determination and configuration, and lower-layer optical network devices that execute settings, allowing each component to focus on specific tasks and reducing overall integration complexity

AI summary
An orchestrator includes: a communication request reception unit that receives a communication requirement from a first computer; an optical transport NW design unit that determines an optical path to be used for communication based on the communication requirement and a state of an optical transport path of an optical transport network and calculates setting information to be set to an optical network device of each of a plurality of nodes to construct the optical path; a result output/transmission unit that transmits the setting information to the optical network device to each of the plurality of nodes; and an ACK transmission unit that transmits the setting completion notification to the first computer after receiving a setting completion response of the setting information from the plurality of nodes.
