X-Haul Network

Provide experimenter customizable and sliceable front- /mid-/back-haul network and edge cloud research platform supporting research on:

• High capacity, low latency radio/edge cloud networks
• mmWave and fiber convergence
• Optical networking
• SDR/SDN and cloud computing
• Testbed control and management

Saving Capacity

• Adding midhaul

processing reduces wavelength blocking

• Reduced BW &

Improved efficiency

• Additional latency

Optical Switching

• Use both for configuring topology for

different/concurrent experiments & converged wireless/optical experiments

– Slicing by wavelength or space

• Stackable whitebox ROADM 1 RU

– Switching time:

• ~ 1 second

– Includes optical amplifiers – SDN controlled

• High port count space switch

– Switching time: ~ 100 ms – SDN controlled

mmWave Analog RoF

• Ultra-low latency, simple radio head

– No digitization until data center

• COSMOS: Sub-6 GHz, plus select routes to 40 GHz

– Can mix down from higher frequencies

• Other bands?
