Traditional mobile networks are based on stand-alone Base Transceiver Stations covering a radio area. BTS overlap to provide a wide coverage to mobile users and are connected to the mobile core network through a backhaul network. Cloud Radio Access Network is a new architecture for mobile access networks that rely on simple radio front-ends connected to a pool of remote network resources. By leveraging cloud infrastructures, CAPEX and OPEX is lowered substantially.

5. 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

6. 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
