Summary
This study introduces a novel 3-D optical labeling scheme for scalable optical packet switching (OPS) networks. This method significantly increases optical code (OC) label capacity, enhancing network performance.
Area of Science:
- Optical Networking
- Telecommunications Engineering
- Information Theory
Background:
