Optical Power Orchestration Adapter for Logical-Physical Passband Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Orchestrated line systems in C/L-band optical transport networks face complexity and scalability issues due to device-specific constraints being managed by the orchestrator, leading to a mismatch between logical and physical views.
Innovation Solution
An orchestration adapter acts as middleware between the orchestrator and control block, facilitating communication by adapting logical-view operations into physical-view requests and consolidating responses, using a mapping between logical and physical passbands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the orchestrator manages device-specific constraints directly, then device control capability is improved, but orchestrator complexity increases and scalability deteriorates
Solution Approach 1:
The patent extracts device-specific constraint management from the orchestrator and places it in a dedicated control block. The orchestrator retains high-level resource allocation and scheduling functions, while the control block handles device-specific configurations, passband mappings, and operational constraints. This separation reduces orchestrator complexity while maintaining device control capability.
Solution Approach 2:
The patent introduces a control block as an intermediary layer between the orchestrator and optical devices. This mediator translates high-level orchestrator commands into device-specific operations, managing the complexity of device constraints without burdening the orchestrator. The control block handles passband-to-channel mappings and device-specific power control while the orchestrator focuses on network-level resource management.
2Adaptability or versatility
If the orchestrator operates on a logical view different from the device physical view, then orchestrator independence is improved, but communication complexity between orchestrator and control block increases
Solution Approach 1:
The patent introduces a passband abstraction layer that bridges the logical and physical views. The control block maintains passband-to-channel mappings that translate logical-view passband identifiers into physical-view channel configurations. This additional dimensional mapping allows the orchestrator to operate independently on logical resources while the control block handles the translation to physical device parameters, reducing communication complexity.
3Adaptability or versatility
If a single logical-view operation request is decomposed into multiple physical-view operation requests, then device-specific constraint handling is improved, but processing time increases
Solution Approach 1:
The patent implements preliminary action by pre-computing and storing passband-to-channel mappings in the control block. When the orchestrator sends a logical-view operation request, the control block already has the necessary mapping information to quickly translate it into physical-view operations. This eliminates the need for real-time decomposition calculations, reducing processing time while maintaining the ability to handle device-specific constraints.

AI summary
An orchestration adapter of an optical network is herein described. The orchestration adapter comprises a processor and a non-transitory computer-readable medium storing processor-executable instructions that, when executed, cause the processor to: store a mapping of a correspondence between logical-view passbands and physical-view passbands, each of the physical-view passbands comprising one or more partition(s), each corresponding to a particular logical-view passband; receive a logical-view operation request from an orchestrator of a network element, the logical-view operation request identifying an operation and a first logical-view passband, the operation being executable by a control block of the network element; and send a physical-view operation request to the control block, the physical-view operation request comprising instructions to cause the control block to execute the operation, the instructions identifying the operation and a first physical-view passband, a first partition of the first physical-view passband corresponding to the first logical-view passband.
