    A novel two-bounce interconnection architecture optimizes network design. This approach minimizes optical links for global connections while retaining electronic switching efficiency, validated experimentally.

    Area of Science:

    • Computer Engineering
    • Network Architecture
    • Optical Interconnections

    Background:

    • The Benes network is a minimum rearrangeable nonblocking network.
    • Existing architectures often require extensive global interconnections.

    Purpose of the Study:

    • To present a new two-bounce free-space arbitrary interconnection architecture.
    • To reduce the number of global optical interconnections required in network design.

    Main Methods:

    • Topological transformations applied to the Benes network.
    • Hybrid approach combining global optical and local electronic interconnections.
    • Experimental validation of the proposed architecture.

    Main Results:

    • The two-bounce network requires only two stages of global optical interconnections.
