Moving the boundary between wavelength resources in optical packet and circuit integrated ring network

Area of Science:

• Telecommunications Engineering
• Optical Networking
• Network Resource Management

Background:

• Optical packet and circuit integrated (OPCI) networks combine optical packet switching (OPS) and optical circuit switching (OCS) on shared infrastructure.
• Wavelength multiplexing enables simultaneous OPS and OCS links for diverse service requirements.
• Dynamic resource allocation is crucial for OPCI networks to adapt to fluctuating user demands.

Purpose of the Study:

• To propose a resource-adjustable hybrid optical switch and transponder for OPCI networks.
• To demonstrate the feasibility of distributed control for dynamic resource adjustments in OPCI ring networks.
• To enable automatic wavelength resource boundary movement between OPS and OCS links based on real-time demand.

Main Methods:

• Development of a resource-adjustable hybrid optical packet/circuit switch and transponder.
• Implementation and testing of a distributed control mechanism on an OPCI ring network testbed.
• Experimental validation of dynamic wavelength resource allocation and boundary shifting.

Main Results:

• Successful demonstration of dynamic resource adjustment between OPS and OCS links.
• Verification of distributed control for managing wavelength resources in an OPCI ring network.
• Automatic allocation of shared resources and flexible boundary movement achieved based on optical path usage.

Conclusions:

• The proposed hybrid switch and transponder effectively supports dynamic resource allocation in OPCI networks.
• Distributed control is a viable strategy for managing resources in OPCI ring network testbeds.
• OPCI networks can efficiently adapt to changing service demands by dynamically adjusting wavelength resources between OPS and OCS links.
