1. GoS: Guarantee of Service Introduction 1

2. Agenda Challenges The Key Problems Opportunity Solution Overview Use Cases Why is This Unique? Key Benefits Key Features Who We Are How Can We Help You? 2

3. Challenges Across all segments, IP traffic is growing dramatically Outpacing revenue growth Investment in bandwidth capacity is inevitable But CAPEX intensive and never-ending Efficient use of bandwidth CAPEX demands of infinite bandwidth investment OPEX for delivering services Growth in real-time or near real-time applications Customer expectations rising Growth in data traffic disrupts expected QoS Especially with real-time applications 3

4. Challenges Demand for Quality of Service and Quality of Experience is growing Consumer Enterprise Operators and service providers need to monitor and enforce policies End to end QoS Differentiated services and price plans Policy as a revenue generator There is a need to monitor, measure and enforce QoS to ensure appropriate QoE for all users 4

5. Bandwidth Challenges 5

6. Revenue Decline in All Segments 6

7. Mobile Challenges Bandwidth pressure Congestion Fair delivery Application performance Revenue pressure Mobile voice revenue to peak in 2010 9.6% decline by 2014 from $580 billion (ABI Research) Mobile data prices falling 7 Decline in cost per MB of mobile data, 2009 – 2014 (Informa TM)

11. Fixed Challenges Fixed voice and data revenues are in decline Despite massive data growth Increasing use of real-time or time-sensitive applications has created demand for QoS Initially in specific segments such as gaming Likely to spread Available bandwidth restricted Expectations for fair delivery over xDSL is growing Service providers need to address consistent, not peak rates to achieve realistic QoE Policy is emerging as a key area Policies require QoS reporting, management and enforcement solutions 11

14. The Key Problems How can service providers and systems integrators ensure QoS at the edge of the network? Multiple competing applications Different QoS requirements Different user QoE expectations Service providers need a means to differentiate for competitive advantage based on network performance Fair resource allocation for all? Guaranteed performance? Monetise QoS for enterprises and consumers? Reduce OPEX from solving QoS problems? Ensure profitable SLAs? 14

15. Opportunity QoS is now demanded by consumer and enterprise users Expected QoS is an asset Emerging willingness to pay for differentiated service quality Service Providers can differentiate through QoS / QoE Subscriber retention Subscriber acquisition Manage CAPEX efficiently Avoid over-provisioning Monetise policy driven QoS Up-sell premium quality QoS has value Ensure reliable delivery of real-time applications How? 15

16. The Solution: GoS Guarantee of Service The most advanced QoS solution available The only way to ensure the predictable delivery of true QoE for real-time services over changing end-to-end networks Guarantee the performance of revenue-generating services and applications Multiple critical real-time and non-real-time services Voice and Video work properly together over congested links The only truly portable QoS monitoring and enforcement solution Deliver real-time, parallel services, reliably and efficiently Even in congested networks Achieve 100% bandwidth utilisation Prioritised real-time traffic plus best effort delivery 16

17. Overview 17

18. Overview GoS is licensable software Embedded into access devices or any service demarcation device Manages packet traffic flows at the true edge of the network Towards different connected interfaces Enables “throttling” Plug and Play customer configurations No complex preparation Automatic updates (based on real usage) Deliver real-time statistics for monitoring and diagnostics QoS and Bandwidth Usage Reporting and Alarming Measure, Manage & Enforce QoS and Policies At network boundary 18

19. Guarantee of Service “GoS” The most advanced QoS solution available QoE for multiple revenue-generating real-time & non-real-time services All applications receive consistent QoS determined by service provider Even during maximum congestion Independent control over loss and delay Automatic customer configurations Dynamic re-configuration based on session setup/teardown Efficient Fills the link 100% while guaranteeing 90% for quality traffic Meet QoS requirements without need to overprovision or reserve bandwidth Control network congestion from source Deliver real-time statistics for monitoring and diagnostics QoS and Bandwidth Usage 19

20. GoS Quality Model GoS organises traffic into Quality Groups Depending on classification rules Each Quality Group has a bandwidth allocation This can be strictly enforced (excess traffic is dropped) Or it can be a guaranteed rate (excess traffic is forwarded if capacity is available) The sum of the Quality Group bandwidths can be up to 90% of the link rate Unassigned and unused bandwidth is used for Best Effort traffic Each Quality Group is assigned to a GoS Class Loss and delay are prioritised independently (three levels of each) Decouples different types of priority for e.g. Voice and control This determines the worst-case loss and delay experienced during congestion 20

21. What GoS Does 21

22. Deployment Options 22

23. Use Cases Unified Communications, Collaboration and VoIP Services Video Services Connected Home Monitoring and QA 23

24. Use Cases: UC, Collaboration and VoIP Profitably deliver real time, business communications services Media Collaboration Tools Unified Communications Audio / Video Desktop Conferencing Improve voice quality and enterprise VoIP services with managed QoS Deploy GoS in enterprise access gateways Multi Service Access Gateway Fair allocation of bandwidth based on real-time application requirements Monitoring, measurement and enforcement capabilities Leverage existing network without costly over-provisioning 24

25. Use Cases: Video Services QoS software to support rapid growth in video conferencing applications To the desktop Consistent user experience Reduced OPEX Solve latency issues to ensure service success Deploy GoS in enterprise access gateways Multi Service Access Gateway Fair allocation of bandwidth based on real-time application requirements Monitoring, measurement and enforcement capabilities Leverage existing network without costly over-provisioning 25

26. Use Cases: Connected Home QoS solution to deliver QoE for consumer applications Gaming, P2P, Over The Top Video Services, IPTV Deliver consistent low latency and ping time Overcome lag problems for real-time applications Fair allocation of bandwidth based on real-time application requirements Monitoring, measurement and enforcement capabilities Implement and enforce priority services Premium packages for niche markets Gamers New revenue opportunities Deploy GoS in consumer Connected Services Gateways Service all broadband applications equitably 26

27. Use Cases: Monitoring and QA QoS and Bandwidth Usage at point of service demarcation Reporting and Alarming WAN link rate LAN connectivity & diagnostics Application identification Real-time and passive Diagnostics for fault resolution SLA management Plug and play QoS configuration with dynamic updates Identify encrypted traffic GoS Framework solution available for managing access to an entire network 27

28. Why is This Unique? 28
