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
