Cloud RAN Architecture 
 Relying on a high speed 
fronthaul, Cloud RAN moves 
L1 (if fully distributed), L2 and 
L3 functions in central 
servers 
Cost-effective low power 
remote radio unit (RRU) 
Centralized architecture on 
standard servers for CAPEX 
and OPEX reduction 
©6WIND 2014 v1.0 | 5
Cloud RAN Virtualization (NFV Use Case) 
 Very high communication requirements 
between BBU’s L1 and L2/L3 functions 
inside the server at the hypervisor level 
 Complex and low-latency packet 
processing at the hypervisor and VM 
level including VLAN, link aggregation, 
GRE, IP in IP, GTP, shaping, NAT, 
firewall, IPSec… 
 Fast and low-latency VM to VM 
communications (L2 to L3) 
 Compared to standard VMs, BBU VMs 
rely on 
 Real-time OS services 
 Efficient VM migration mechanisms

 High performance switching aggregated bandwidth for workloads without any 
modification in the virtual switch 
 1/10th computing resources to process a defined amount of bandwidth, saving 
computing resources to implement more VNFs 
 Hardware independent VNF network attachments for seamless network hardware 
upgrades and VNF migration 
 Low-latency inter-VNF communications 
 Enhanced features beyond switching (L3 forwarding, virtual routing, firewall, IPsec 
and more) for extended chaining capabilities

• Aggregate 500 Gbps bandwidth with low latency 
• No external limit to number of chained VNFs 
Physical Switching Limitations 
• Hardware dependent switching 
(SR-IOV, RDMA, NIC embedded switching) 
• Throughput is limited by PCI Express (50 Gbps) 
and faces PCI Express and DMA additional 
latencies 
• Available PCI slots limit the number of chained
