Network Virtualisation – A Service Provider’s Perspective Presented by: Steve Legge, Chief Operating Officer 8 May 2007 The Evolution of SOUL • Australian broadcasters required a broadband network for Digital TV (DTV) • Buy or Build? Optus or Telstra were the only bandwidth resale options … (both expensive) • NBN therefore elected to build excess broadband capacity at minimal marginal CapEx and OpEx • A separate entity was created as a licensed carrier to facilitate the sale of excess capacity, adopting the Soul Pattinson name • Convergence of broadcast television and telecommunications content and distribution successfully implemented across the network • The business and network expanded along eastern seaboard of Australia Who is SOUL? • The largest operator of ‘greenfield’ MPLS based IP networks in Australia • The only national PSTN interconnected IP network in Australia • Voice, video and data over a single, national IP network • Fibre network throughout intercapital and regional Australia • In excess of 300 points of presence (PoPs) Who is SOUL? • Network has full QoS feature support with Service Level Guarantees to support lower latency, packet loss and jitter • 100% Powered by Cisco Systems – Single vendor platform • Infrastructure is SOUL owned and operated, and independent of Telstra • In excess of 900 employees in offices throughout Australia • Consumer Call Centres in Perth and Sydney Network Design • The network was initially designed for DTV Transmission • Provides higher availability than standard Telco networks, as the network core cannot suffer any downtime • Increased redundancy in all layers • Architecturally different to other telco networks as design is optimised for content delivery, not just traditional services • This increases the access to regional areas due to distributed core design • Diverse fibre paths also operate across the country for redundancy • Capability exists to rapidly increase regional reach (new POI deployments) New Demands on the WAN Business Imperatives IT Applications WAN Implications • Reduce cost • Collaborative apps • Any-to-any • Increase productivity • B2B applications • Scalable bandwidth • Improve Responsiveness • Web services • Convergence • IP telephony • QoS • Video applications • Security • Storage / back-ups • Availability • Content distribution • Remote access • Distributed data centers • Web integration • Teleworkers • Manageability • Build resilience • Focus on core competencies More Complex Communities of Interest • IP Telephony drives PVC growth • Full mesh for media bearers • Separate voice and data PVC’s • Larger PVCs for desktop video • Shared services require PVC’s back to data centres • Ultimately a cost that you bear • Direct • Via Service Provider • Network Performance Frame Relay vs QoS IP VPN Costs Frame Relay Application Demands QoS IP VPN Degree of Meshing Hub and Spoke Full Mesh Source : Ovum, 2003 A compromise between performance, customer satisfaction & budget More Complex

Technical Performance • Enable a range of applications from voice to video, content, and storage • End-to-end QoS for data, voice, and video • Increased productivity • • Improved communication effectiveness Affordable, any-to-any connectivity and enhanced network availability • Any access speed and technology • Focus on core competencies • • Closer ties to partners and suppliers Security and privacy equivalent to or better than Frame Relay and ATM • Lower communications & improved productivity for remote users • Support private IP addressing plans • Favorable price/performance ratio of IP networks The Next Generation Leased Line • Driven by business & market needs • Enterprises AND Service Providers • More complex communities of interest • More complex connectivity demands • Appetites for Value-Added Services • Migration from ATM/FR is NOT just about cost 1. Scalability 2. Reach 3. Security 4. Application convergence 5. Enabling evolution Source : Business Communications Review / InfoTech Why Choose SOUL? • “SOUL-owned” competitive infrastructure, providing an alternative to traditional Telco incumbents • New and improved broadband products and services to metro and regional communities • Commitment to our Customers and their business • Commitment to solution delivery • Premium purpose built network designed to support real time applications In Summary • SOUL - one network • Greenfield National MPLS – IP Network • True convergence – Broadcast video, carrier voice and private data across one MPLS network • Consider convergence across the business • Network, Service, Application • Broadband IS and WILL BE the delivery enabler • Economics of multiple services • SPs must continue to enforce a place in the value chain
