Market Trends & Challenges
The Mobile Network in 2011 and 2012
� Last year’s mobile data traffic was eight times the size of the entire global Internet in 2000.
� Mobile video traffic will exceed 50 percent for the first time in 2011
� Smartphones represent only 12 percent of total global handsets in use today, but they represent over 82 percent of total global handset traffic.
The Mobile Network in 2016
� Global mobile data traffic will increase 18-fold between 2011 and 2016
� Two-thirds of the world’s mobile data traffic will be video by 2016
� Mobile-connected tablets will generate almost as much traffic in 2016 as the entire global mobile network in 2012

Security Devices in LTE
� LTE or Mobile networks are full of security devices

Top 10 Testing Tips for Security Devices
1. Application Mix
� It’s important to tune the devices appropriately for the application running within the environment
� A simple mix of HTTP,SMTP,DNS,FTP may not be a good representative of your network
� The device under test should also be configured to protect all the applications.
2. Packet Size Mix
� A “normal” RFC 2544 is not recommended
� Instead of using single Packet sizes use a MIX different Sizes
� To understand the traffic mix administrators can use a protocol analyser to collect statistics form the real-life environment

3. Security Coverage
� It’s important to tune the devices appropriately for the application running within the environment
� Don’t use the “Standard” preconfigured filters, signatures and rules
4. VLAN Tagging
� VLAN Tag will consume processing resources within the security device
5. IPv6
� Use IPv4 and IPv6 simultaneously
6. Attacks Traffic
� Mix of both legitimate and malicious traffic
7. TCP sessions
� Ensure that performance test are conducted with a appropriate amount of TCP Sessions

8. Physical Connectivity
� Test Setup must reflect the real-life physical environment
� For modular designed devices it will be important to test traffic going into one module and out of a different module
9. Performance Testing for Long-Haul
� Take into account that the device will likely need to support growth over his lifetime.
� Global IP traffic is expected to increase fourfold over the next five years.
10.The Point of Failure
� One of the final tests is to find the point at which the device essentially fails.

It’s all about apps
12 PROPRIETARY AND CONFIDENTIAL
What is there to test?
� Applications suffer from low bandwidth
• Response time goes low
• Retransmissions saturate the network
� Applications are not always designed for Mobile
� Application are still very similar to fixed Internet
• Browsing
• Skype
� Infrastructure testing with multiple applications is a must
13 PROPRIETARY AND CONFIDENTIAL
Testing these applications
� This is very similar to testing applications in the web. Hence the web is providing the services.
� The extra comes with the mobile bandwidth that can be reached with multiple emulated users.
• Bandwidth has impact on performance of the application
• How many mobile users a can you handle

Most of the traffic is to be Video…
16 PROPRIETARY AND CONFIDENTIAL
How does that work
For ABR to work, a video is first encoded at different bitrates to accommodate varying bandwidth connections. Each bitrate version is sliced up into tiny fragments —typically 2 to 10 seconds.
The video player then pulls fragments from the different encodings and inserts them into the stream as bandwidth dictates.

Adaptive Bitrate Streaming –The 4 C’s of Streaming TV
Consumption - Adapting to bandwidth, network conditions, and client CPU usage to deliver uninterrupted video
Connections - Client responsibility to request appropriate bit rate(s)
Continuity - Minimize delay by using WAN
acceleration technologies (caching
appliances)
Content - Cache video content on the edge and
distribute based on client requests
