What is Campus “Slicing”?Partition network for multiple user-communities – “Sandbox” R&D dept.

Test network # 1

Test network # 2

Test network# 3

Market Status

• Slicing only on isolated networks today (lab)

• Current open source components not suitable for production networks

• Researchers need to expand network connectivity

• IT needs more rapid provisioning capabilities

Consistent policy management for maximum flexibility and Innovation
