Setting the Scene
Why Cloud for Telecom Operators

9
The importance of Cloud Services to Operators
 Eagerly seeking services: A strong desire to make money out of
cloud market
 Traditional sources of revenue (communications services) are
declining, especially in developed markets
 According to Heavy Reading study early 2012 with 149
operator respondents:
• ~60% of operators are familiar with cloud
• ~80% of operators have a cloud evaluation team in place
• 55% already purchased cloud technology
• >40% of operators have already launched multiple cloud services
 Cloud services are a big driver for SDN and NFV

10
Future of Telco Business Linked to Three Emerging Technologies
 Virtualization
• Abstracting networking software (functions) from dedicated hardware and
running in virtual machines on COTS platform
• NFV initiative specifically is about consolidating many network equipment
types onto standard high volume servers, switches and storage in a cloud (ie
elastic, resource pooled, orchestrated ) environment
 Software-Defined Networking
• Creates network abstractions to enable faster innovation
• Using virtualization techniques, e.g. network overlays to create programmable
data center networks
• Using protocols/technologies such as OSS/orchestration and management
systems to create programmable WAN
 Cloud
• Layer of automation/orchestration on top of virtualization that provides NIST
cloud characteristics
• Distinction emerging between “resource cloud” and “application
management cloud”

Real-time ! = Average Latency
• Real-time applications need determinism
• Primary criteria: Maximum Latency (i.e. Low Jitter)
• Average Latency also important, lower is better
• 99%ile Latency: track trend in reducing outliers contributing to
maximum latency
• RT features available in ESXi 5.5

23
Average Latencies in ESXi 5.0
 Benchmark: Ping (ICMP) Kernel space <-> Kernel space
 VM I/O Path: vmxnet3 vNIC/vSwitch -> Intel 82599 10GbE pNIC
 Latencies: Average HRT (Half Round Trip) in microseconds

Amdocs Online Charging System
OCS is part network, part IT, part business
 These are not packets, this is money
It is challenging:
 Highly sensitive to latency
 Network grade high availability
 Highly tuned and hardware optimized
A lost event, is a lost dollar

33
Virtualizing Amdocs Online Charging System
SUCCESS
• Virtualized OCS results are on par
with the physical deployment
A joint VMware and Amdocs certification was held
• Physical environment compared to virtualized
• Production like, high loads
We had some concerns
• Virtualization may add latency overheads
• Separates OCS from physical hardware
• Real time aspects of continuous processing
!

34
VMware Certification Results
Comparing virtualized OCS and physical
is comparing apples to apples

Wireless Cloud Element Feature Roadmap
Leverage benefits for Network Function
 Multi-Tenancy – GSM, W-CDMA,
and LTE applications share
physical resources
 Horizontal Scalability – number
of CPUs controls capacity
(flexible configurations)
 Elastic Capacity – the capacity of the
system can change quickly according
to need
 Reduced Power Usage – as capacity
breathes throughout the day hardware
can power up / down
 Geographic Redundancy – a fault in
one location does not disable the system
 Zero Downtime Maintenance – VMs
move to other hardware for maintenance

Dense Urban

As traffic shifts during the day ...
... server
load is
uniform

41
Transformation from 9370 to WCE RNC
 The WCE virtual RNC needs to scale
horizontally to much larger capacity
than possible with the 9370
 Two problems must be addressed:
• N2 Communications
• Scope of Failure
 Reorganization of existing 9370
code allowed for the creation of
a component responsible for cells
and another responsible for user
equipment (UEs)
 As UEs (and UMUs) are
independent of each allowing
for horizontal scalability
 The scope of failure is greater
reduced as UMUs don’t
require sparing

 Spared Roles
(SWACT in a few seconds):
• CMU (N+M) – Cell Management
• 3gOAM (1+1) – OAM termination
• PC (N+1) – Public / Private
network gateway
 Unspared Role
(Return to capacity ~ 60s):
• UMU - UE Management (UE Call)
& RAB UE Packet processing
 Platform Components:
• vCenter Server – VM Management

RNC Real-time Requirements
 A controller’s user-plane
components typically need
very precise timing, e.g.
 The RNC must send downlink
packets such that they arrive
at the NodeB within the Time
Of Arrival Window
 When the user goes into
Diversity mode the RNC’s
transmit window must
compensate for different
transmission times
 Six NodeB may be involved in
a single user’s connection
which currently reduces the
RNC transmit window to 5ms

44
Non-deterministic Timing
 Deterministic timing not
possible within a virtualized /
cloud environment
 Virtualized Network
Functions must compensate
for timing uncertainty
 Data for this chart was
extracted from the virtualized
RNC while running an hour
long traffic test
 Note: this system was
running with ESXi 5.1;
significant improvements are
expected from ESXi 5.5

45
Interval Scheduling
 Interval scheduling allows
for variable amounts of time
between events
 At each event an accurate time
reference is read and the interval
between events is calculated
 Based on the elapsed time and the
priority of work that needs to be
done a work schedule is created
that ensures isochronous work is
completed first at the potential
expense of background work

46
Shadow Network Functions
 WCE provides the capability to
create a “shadow” of a network
element within the same physical
hardware as the service providing
network element
 This shadow can be used for:
• Fast and Graceful Reset
• Software Upgrade
• Software Configuration Change
• Virtual or Physical Machine Change
• Geo-Redundancy
 Roll-back to the previous version
is possible after an upgrade
