5G-Crosshaul - Main Building Blocks
• XCF – Common Frame capable of transporting the mixture of various Fronthaul and backhaul traffic
From pure heterogeneous
backhaul to unified 5G-
Crosshaul network

XFE
• XFE – Forwarding Element for forwarding the Crosshaul traffic in the XCF format under the XCI control
XCI (SDN/NFV-
based)
• XCI – Control Infrastructure that is SDN-based and NFV-enabled for executing the orchestrator’s resource allocation decisions
XPU
XPU
• XPU – Processing Unit for executing virtualized network functions and/or centralized access protocol functions (vRAN)
Network Apps
• Novel network apps on top to achieve certain KPIs or services
From fixed ptp fronthaul links to
unified 5G-Crosshaul network
A holistic approach for converged Fronthaul and Backhaul under common SDN/NFV-based control, capable of supporting new 5G RAN architectures (vRAN) and performance requirements
