Solution and Architecture



What is Landslide ?

Mobile packet core networkperformance, load, scalability,and traffic modeling test tool

Emulates wide range ofnetwork components to allow

single node and end-to-endtests configuration

Emulates millions of mobileusers to stress even the mostscalable devices and networks

Combined control plane anddata plane traffic to test allaspects of network



Spirents Landslide is the only solution that canprovide

Complete Interface Simulation and Protocol Coverage (2008 - 2011 3GPPrevisions)

Full Mobility Testing capabilities:

Intra-RAT and Any-G to Any-G !!!

Combined Capacity and Session Loading testing with Mobility

Topology Emulation Emulate Complex Network topologies from a singleplatform

Node Wrap-Around

Progressive end-to-end

Flexible Traffic modeling:

Decoupled Control and User Planes

Multi-play Stateful, Stateless and/or External configurable data traffic

Test Case combination and automation

The deepest level of configurability including Message and IE corruption

IxCatapultOverview

Product Detail

Functional Tester - flexible but difficult

Excellent 3G/4G protocol support

Very weak stand-alone data throughput

Good mobility performance control planeONLY

CurrentStatus

Sales down 26% in 2010

Developing LTE features

Using custom engineering and outsourcing to

resolve difficulty issue Have moved some resources to IxLoad

Ixia sales force aggressive on price

Spirent Solution Benefit

Technical AdvantagesBusiness Benefits to

CustomerHow do we neutralize?

Full range of state machinebased wireless protocols

Chassis based architecturesupports full bandwidth of765 Gb/sec

Streamlined GUI based onthe Eclipse RCPArchitecture

Full test coverage from asingle tool

Simply add additionalmodule to meet capacityand scale requirements

Short Release Train cycles

Graphically create callflows

User-friendly testexecution and reportingenvironmentnot usedtoo sluggish

Catapult is a protocoldevelopment tool but isunable to test capacity,mobility and data performance

Good LTE protocol coveragebut stability an issues

Poor configuration features Not user-friendly

configuration, runtime andpost-analysis UIs (all Linuxbased)

No native automation

Due to design limitations a

fully loaded system is only ableto support 9Gbps

In reality Catapult hasmultiple low level GUIs

Customers still have to editlow level code

Integrated IxLoad/IxCatapultProduct Detail

Stateful data performance tester with Control Plane

Product runs from IxLoad (no IxCatapult UIs) No functional testing by default

Targeted at user-plane performance testing

Coupled Control and User-Plane only

CurrentStatus

Very limited coverage of LTE interfaces and nodes(including 3GPP versions and configurability)

GA, Gn, S11, S5, S8

Runs on Xcellon and Accelleron modules

Intra-LTE Mobility only Very aggressive pricing

No Node Emulation

Complex scenarios and node testing still require Catapulthardware

New to the market:

Lack of experience

Limited number of 3GPPreleases

Product incomplete

No Node Emulation:

Difficult to scale labs

No progressive end-to-endtesting

High performance EAST HWbased on ATCA and

Network Processor Units

Effective functional andload testing of signalling

and bearer of LTE EvolvedPacket Core network

elements (MME, S-GW,PDN-GW) via the core

interfaces.

Intuitive Graphical testcase and message editing

tools

Less hardware needed

Simulates heavy load of

control plane and userplane traffic

NetHawk EAST EPC caneffectively be used in

functional and load testingof LTE core network

elements.

Position Landslide 7100B

64-bit multi-threaded codeprovides the highest

capacity in the industry

Nethawk is unable tosupport stateful application

traffic

Landslide is the only testercapable of measuring true

QoE by emulating advancedmobility scenarios with real

application traffic

Similar to Catapultengineers must be

dedicated to learning andsupporting Nethawk

Nethawk is unable toautomate testconfigurations

Quizz

1. How would you check the current license?2. What is the minimum hardware configuration?3. What is the role of the Test Server?4. What is the appliance management port?5. What type of cards can be installed in a Test

Server?6. How many users can use simultaneously the same

TAS? Same TS? Same NIC card?7. Name two of strengths from our competitors and

how do we neutralize them?
