• Optical Packet Switching (OPS)
• All optical processing, transport, and buffering
• Fine-grained WDM channel allocation
• Lack of optical signaling processing, lack of
  optical RAM, and large switching overhead

• Optical Coarse Packet Switching (OCPS)
• Per-burst switching
• Header is electronically processed while the
  payload remains in the optical domain
• Header is in-band modulated with payload and sent
  via one ?
• Wavelengths are shared via wavelength converters
• Enforcement of traffic control and traffic
  engineering to maximize wavelength-dimension
  statistical multiplexing gain
• An Optical Coarse Packet Switched IP-over-WDM
  Network (OPSINET) is constructed
• OCPS network provides superior loss performance
  than out-of-band-controlled-based Optical Burst
  Switching (OBS) network
