RAN Slicing and Sharing Sample Results

• 3 slices:
• Slice-specific scheduling
• Dynamic Slice Resource management

– Enforce different policies over time

Converged Flexhaul for 5G

• Tow type of xhaul
• Low latency
• High latency
• Various topologies
• multi-tier – flat
• Mesh – tree
• Switching vs

routing

• Aggregation
• Distribution
• Data-plane

accelerations

• DPDK, NETMAP
