3. About us • Headquartered in Ottawa, Ontario, Canada • Specialized in bandwidth management and network performance • More than 80 clients worldwide • Strategic Alliances with major vendors (BMC, Computer Associates, IBM, Mitel, etc.) • Intelligent IP traffic management solution—the result of a several million dollar R&D effort 3

4. Challenges FacingGovernments • Business Challenges • Increasing demand for new services • Reduce operational expenses • Provide consistent, reliable service to reduce churn • Increase service quality • Technical Challenges • Control subscribers’ bandwidth utilization • Manage aggressive users (software and content download) • Fulfill service level agreements • Gain visibility into network activity to manage usage • fluctuations and conduct capacity planning 4

5. DybandThe Business Solution • Increase network efficiency • Increase performance while reducing long term costs • Enable more users to access the existing system • Significantly increase ability to monitor and manage the network and users  • Plug and Play (remote configuration over the actual IP link) Dyband increases service margins by delivering new revenues and reducing operating expenses, while providing reliable service to customers. 5

6. DybandThe Technical Solution • Measures and controls the bandwidth use of individuals and groups • Controls aggressive users, minimizes network congestion, reduces packet loss, and eliminates congestion-related outages • Creates and controls SLAs • Provides real-time visibility into bandwidth consumption • Supplies an extensive collection of historical statistics to support capacity analysis and usage-based billing • Provides a single management interface across all access networks (wireline, wireless, cable, satellite) Dyband enables network operators to control subscribers’ bandwidth usage, fulfill SLAs, and deliver consistent, reliable service. 6

7. Meeting the Challenge:Dyband IPTM Dyband enables service providers to: • Gain absolute control of their bandwidth • Eliminate the need to provision bandwidth to meet peak demand • Set the bandwidth access and priority of individuals, groups, departments, or virtual groups via multiple, operator-configurableparameters, including time-of-day • Identify the unsanctioned use of bandwidth by individuals • Enable 25% more users or traffic to the backbone connection without adding more bandwidth Dyband will reduceoperating costs, while delivering a more consistent, reliable service to all users, guaranteeing prioritybandwidth to dedicated critical applications and vital groups. 7

8. Dyband IPTM • Controls bandwidth consumption • By IP address for up to 50,000 managed points • From xDSL to OC-3 (155Mb/s) speeds per device • Allows operators to define and enforceunlimited Service Level Agreements • Enables multiple bandwidth allocationschemes (e.g. guaranteed, preferred, equitable) • Provides time-of-day bandwidth allocation (dynamic and configurable) • Evaluates the network 100 times per second, regardless of traffic load or congestion • Minimizes network congestion, reduces packet loss and eliminates congestion-related outages • View and adjust bandwidth consumption in real-time • Determine who is using bandwidth and at what time. • Gather comprehensive historical statistics • For capacity analysis, bandwidth upgrades, usage-based billing or departmental charge backs 8

9. Shaper Shapes all traffic flows between users and the Internet; collects real-time statistics CMon Application for viewing and modifying network topology, managing QoS and viewing real-time statistics Archiver Extracts real-time stats from shapers and stores them in a SQL database for historical reference Miner Application for generating and viewing reports that contain historical performance data Profile Push Distributes global service profiles to remote Shapers Profile Push departmental Service Policies router Archiver Statistics Control & Monitoring Shaper CMon SQL Database Reports LAN Miner Workstations Dyband Components Dyband is robust and efficient software that you install on industry- standard hardware, enabling the greatest reliability and scalability 9

10. Dyband 2.2 IP Traffic Management • Evaluates available bandwidth capacity 100 times per second • Shapes traffic for up to 50,000 managed objects • Manages inbound/outbound traffic separately • Controls individual and aggregate subscriber usage • Minimizes periods of congestion; dramatically reduces packet loss; eliminates congestion-related outages • Guarantees that no user is “starved” for bandwidth • Prevents bandwidth “hogging” by aggressive users (Optional) 10

11. Dyband 2.2 Service Levels and Management • Enables a range of services at distinct price points • Significantly reduce provisioning time over manual methods • Gain up to 25% incremental revenue without purchasing additional bandwidth by migrating subscribers to service levels that meet their interests and budgets • Time-of-day parameter facilitates optimal use of bandwidth 11

12. Dyband 2.2Performance Visibility • Provides real-time visibility into who is consuming bandwidth • Reports on “Top 10” users, based on operator defined criteria • Enables capacity planning and well-timed provision-ing via historical insight into service performance • Delivers an extensive collection of statistics to support usage-based billing 12

13. Dyband 2.2 Autodiscovery and Configuration • Discovers network topology and displays it in a familiar hierarchical tree structure • Autodiscovers new subscribers and places them appropriately in the topology tree • Allows auto-discovered subscribers to inherit pre-defined SLA profiles • Enables network managers to audit their customers’ IP address space utilization • Simplifies and automates configuration and administration, reducing operational complexities 13

14. Automatically transfers traffic to “stand-by” system upon recognition of a Dyband hardware/software problem Traffic continues to be shaped Statistics continue to be recorded and archived Preset profiles are maintained No single point of failurewill affect an operator’s access services or traffic management Dyband E520 also supports multi-homed networks Router Switch / Hub Interface 1 Interface 1 F-T Interface Interface 0 Shaper 2 Shaper 1 Interface 0 From Mgt.

16. What customers are saying “Dyband allows us to manage the system resources on our HSi network in real time, and dynamically optimize both network performance and our customer's experience. We are very pleased with the Dyband product."Mike Kreller, Telesat, Ottawa, Ontario "The built-in rate ramping feature works extremely well in our network, and improves performance for incoming traffic - as well as smoothing over excessive usage automatically. We finally have complete control over, and visibility into, all of the users' bandwidth requirements on our ResNet."Nick Skelton, University of Bristol, England “With Dyband we can sign a lot of new wireless customers with the confidence that we can control bandwidth.” Barry Williams, Storm Internet, Ottawa, Ontario 16
