Optical burst add-drop multiplexing technique for sub-wavelength granularity in wavelength multiplexed ring networks

Area of Science:

• Telecommunications Engineering
• Optical Networking
• Computer Science

Background:

• Optical burst switching (OBS) is an advanced networking technology.
• Wavelength-division-multiplexing (WDM) ring networks are widely used for high-capacity communication.
• Efficiently managing data bursts in these networks is crucial for performance.

Purpose of the Study:

• To demonstrate optical burst add-drop multiplexing (OBADM) as a practical application of OBS.
• To introduce a control mechanism for managing optical bursts within a WDM ring network.
• To evaluate the granularity and efficiency of OBADM in a ring network setting.

Main Methods:

• Designed a burst identifier (BI) for control information delivery.
• Developed a BI processor for efficient BI handling.
• Performed optical multiplexing and demultiplexing of optical bursts (10-100 µs) in an intermediate ring network node.

Main Results:

• Successfully demonstrated optical burst add-drop multiplexing in a WDM ring network.
• The BI and BI processor effectively controlled optical bursts.
• Achieved optical multiplexing and demultiplexing of short optical bursts.

Conclusions:

• Optical burst add-drop multiplexing is a viable application of OBS technology.
• The developed BI and BI processor facilitate effective control of optical bursts.
• OBADM provides sub-wavelength granularity to WDM ring networks, enhancing flexibility.
