1. NOBEL Stockholm MeetingTelefonica I+D contributions to A2.2&A2.3 Maria L. Garcia-Osma, Jesús F. Lobo, Antonio J. Elizondo, Gabriel Moreno Telefónica I+D NOBEL Stockholm meeting

2. A2.2.1 Route management • Route Management document under development (Proposed ToC and deadlines). • TID Work: • Currently working on the loop algorithm • Report revision • Next work: • WP1 Network scenarios implementation NOBEL Stockholm meeting

3. A2.2.2 Traffic Characterization • Measurement platforms presented: Measurement Platforms used in A2.2.2 • Measurement requirements per partner and activities established: Description and Parameterization of Traffic Models • Future work: • Exchange of traces (begining in Stockholm?) • IP Traffic Trace Anonymization • Open issues: • How to map traffic into application/geographic/… categories • TID Work: NOBEL Stockholm meeting

4. A2.2.3 QoS • Preliminary Report on QoS Monitoring, QoS Requirements and QoS Classes – including Service Level Specification. • TID Work: • Traffic Typology included • General set of QoS classes proposed • Editorial work NOBEL Stockholm meeting

5. A2.3: Tariff models • Tariff models situation • The charging, billing and accounting schemes used in telecommunications and data networks have been quite simple. • Users have been billed with a flat rate, based on their subscription and/or the duration of their connection, for either making phone calls or accessing the Internet. • Users are getting the same quality for all services they use. • In order to support real time services it’s necessary a newer billing policy. NOBEL Stockholm meeting

6. WP2 A2.3: Tariff models • Pricing Plans • There are different pricing plans: • At least a pricing plan is applied to a network variable in a pricing scheme. NOBEL Stockholm meeting

7. Flat fee • Limited flat fee • Step pricing • Pricing by volume Pricing plan • Bandwidth • Data volume • Time • QoS • Network resources • Services Network variables Pricing scheme WP2 A2.3: Tariff models • Pricing Schemes • A pricing scheme will be an algorithm for calculating the charge for some network service. NOBEL Stockholm meeting

8. WP2 A2.3: Tariff models • Several pricing schemes could be pointed out. They will depend on the network variables and the price plan that are evaluated by the service provider. •  Most important pricing schemes are: • Volume based • Content based • Flat-rate • PMP • Priority • Smart Market • Proportional Fairness • Edge Pricing • Expected Capacity • Responsive • Effective Bandwidth • Location NOBEL Stockholm meeting

9. WP2 A2.3: Tariff models Billing system framework works in five layers NOBEL Stockholm meeting

10. WP2 A2.3: Tariff models • For every plan scheme, the parameters used to calculate the final charge will be basically three: • Access charge (i.e.the maintenance costs and the operative costs for the network) • Usage charge (i.e. the bandwidth, the duration and the number of bits transferred) • Service charge (i.e. a videoconference call and for an IP telephone call) NOBEL Stockholm meeting

11. A2.3 Conclusions • The need for charging and accounting may be summarize in the following points: • Control resource usage and reservation in flexible backbone networks. • Give incentives to use only required resources. • Prevent waste of bandwidth. • Provide signals for capacity planning. • Maximize profit. • Minimize total delay and costs. • Get billing fairness. • Avoid congestion. • Accounting has to be flexible, standardized, easy to be measured and easy to be understood by the user. • The metric must be simple, fair and compatible with the wishes of the given user.
