  1. NOBEL WP2 MeetingActivity A.2.4 Krzysztof Wajda, Mirosław Kantor AGH – UST, Department of Telecommunications e-mail: <wajda,kantor>@kt.agh.edu.pl

  2. WP2: Survivability, traffic engineering, techno- and socio-economic studies and evaluations AGH University of Science and Technology • A2.1 - Investigation of advanced survivability concepts for multi-service / multi-layer / multi-domain networks • A2.2 - Study of traffic engineering concepts for end-to-end broadband services for all • A2.3 - Techno-economic analysis of network solutions and evaluation of their economic viability • A2.4 - Socio-economic feasibility studies for investigating and assessing new social and economic opportunities • A2.5 - Definition and assessment of different business models for the solutions proposed by NOBEL

  3. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport services AGH University of Science and Technology • overview of charging models • definitions • the role and key aspects of charging mechanisms • overview of charging/pricing schemes • evaluation criteria for charging schemes • analysis of charging model applicability for transport services

  4. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesDefinitions AGH University of Science and Technology • Metering • comprises the process of tracking and recording the usage of the resources by observing the traffic flows. The metering policy, used for configuring the metering layer, specifies the attributes of the traffic flows to be observed • Accounting • consolidates the information obtained from the collecting layer either within the same provider domain or from other provider domains, and creates accounting data sets or records which are passed further to the charging layer • Charging • derives charges from the accounting records based on service specific charging and pricing schemes, which are specified by the charging policy • Billing • collects the charging information (given in charging records) for users over a time period, e.g. one month, including subscription charges and possible discounts into abill.

  6. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport services Key aspects of charging model AGH University of Science and Technology • Cost recovery • Network control and management • Improvement value of services perceived by users • Charging should be • predictable • undersandable • implementable • auditable • transparent

  7. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesCharging schemes AGH University of Science and Technology • A charging scheme is an algorithm for calculating the charge for some network service. In the case of telecommunication services, a user’s charge is calculated based on accounting data that contain information regarding the resource consumption for that user, and prices from tariff tables published by the provider.

  8. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesCharging model parameters AGH University of Science and Technology • Charging parameters • „amounts” of service usage • Tariff parameters • price per unit • Attributes • service and context related parameters, e.g. time of day, distance • Charging function

  9. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport services Pricing schemes AGH University of Science and Technology • Flat-rate pricing • Priority pricing • Paris-Metro pricing • Smart-market pricing • Edge pricing • Effective bandwidth pricing • Proportional fairness pricing • others

  10. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport services Evaluation criteria for charging schemes AGH University of Science and Technology • Compliance with existing technologies • Measurement requirements for billing and accounting • Support for congestion control or traffic management • Provision of individual QoS guarantees • Degree of network efficiency • Degree of economic efficiency • Impact on social fairness • Pricing time frame

  11. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport services What to charge? AGH University of Science and Technology • Components of charge • access charge • usage charge • congestion charge • quality of service charge • value-added service charge • Charging • guaranteed services • congestion • flexible contracts • multicasting • interconnection

  12. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesIssues related to charging AGH University of Science and Technology • Scalability • Hierarchy • Data Collection • Authorization and credit control • Billing cycles and accounting cycles • Discounts and special packages • Authentication and fraud prevention • Account receivable handling • Payment processing • Data management and reporting • Data analysis and data mining

  13. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesResource UsageMeasurement(proposed framework) AGH University of Science and Technology • ISP (Internet Service Provider) • Dial-up login/logout • Number of bytes/packets received/transmitted • Protocols, destinations • Protocol-specific data • CSP (Content Service Provider) • Web activities • Web requests • Video streams, data items, database queries • Content-specific data

  14. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesChoosing the Right Metric AGH University of Science and Technology • What is the Right Metric? • Simplicity • Fairness • Incentive compatibility • Criteria • Easy to measure • High correlation to resource usage • Easy to understand

  15. WP2 - A2.4 – AGH Task 1: Definition and evaluation of charging models for transport servicesRelated projects AGH University of Science and Technology • CA$HMAN • CANCAN • CATI • QUASIMODO • ?
