Area of Science:

• Computer Science
• Optical Networking
• Telecommunications

Background:

• Multihop shuffle networks are crucial for high-speed data transmission.
• Contention resolution in optical networks often requires complex mechanisms.
• Existing packet-switching schemes can suffer from high latency and cost.

Purpose of the Study:

• To propose a novel all-optical packet-switching scheme for multihop shuffle networks.
• To reduce latency and improve cost-effectiveness in optical packet switching.

Main Methods:

• Implementing deflection routing as the core contention-resolution principle.
• Utilizing partial address information for routing decisions, avoiding full header look-ups.
• Designing network nodes with a constant number of demultiplexers regardless of network size.

Main Results:

• Achieved extremely low latency operation at each network node.
• Enabled a cost-effective node design due to a constant number of demultiplexers.
• Demonstrated the feasibility of an all-optical packet-switching scheme with simplified routing.

Conclusions:
