Agenda

• PSTN & Internet trends & characteristics• Why this conversation now ?• NGN – all IP vision• Emerging NGN Service Trends

Business, Consumer• Building the NGN

Architecture, Access, Edge, Transport, Core, Provisioning, Reliability, Security• Transitions in SP Networks

Current, Emerging, Future• Interworking with legacy networks• Importance of Open Standards Interfaces• Summary


Today’s Carrier Networks

Telecommunications• Connection Oriented• Centralized intelligence and control• HW Fault tolerance• Deterministic• Services integrated with network,

limited value-add• Low Latency• Tightly coupled• Mature Security

Data Communications• Connectionless Oriented• Distributed intelligence and control• SW Fault tolerance• Non-Deterministic• Decouple services and network,

Why this conversation now..?

• Old business models being questioned due to success of internet• SP NGNs to adopt IP based internet models except try to make them

better• Call control understandings for IP like SIP, MPLS make it ready to carry

voice and multimedia traffic• SPs need to rework their business models and start growing profitably

again again• Economies expected to become better and SP capex expected to

increase; SPs on verge of making network infrastructure investment decisions

• Credible equipment providers now being tested on new metrics of staying power

Focus on Standards

• By focusing on ITU and other global stds, Cisco is emphasizing Carrier Class on all it’s products

• By focusing on meeting ITU and other global standards Recommendations on Performance, Reliability, Availability Cisco is addressing carrier class requirements


Future Commitment

• Cisco fully committed to open stds interfaces for intercarrier & multi-vendor interoperability

• Putting optimum resources behind participating in IETF, IEEE, ITU-T and various Forums

• Helping in driving towards consistency across divergent standards activities

• Encouraging strong stds focus on products


Summary

• SP Next Generation Networks must become a more reliable and deliver Business-class internet

• Inter-working between SP NGN networks with the PSTN and the Internet are mandatory

• Interconnections between carriers for IP based services are becoming important

• New investment, business model environments require rethinking past paradigms

• Network version of Moore’s Law mandates clear understanding of NGN and where equipment investments will be made
