Enhancing Inter-Domain Networking in ORCA: Resource Arbitration and Path Computation Strategies

This document explores the advanced functionalities and methodologies within the ORCA framework for inter-domain networking. Key topics include resource arbitration and leasing mechanisms, the assembly of abstracted NDL models for inter-domain topology, and the implementation of experiment control tools. We also delve into path computation delegation, redemption of domain NDL models, and provisioning requests with authority-side handler plugins. The goal is to extend networking capabilities across layers, improve resource delegation, and boost performance in resource assignments.
