Biography

Peter Racz received his Ph.D. degree in Computer Science from the University of Zurich in 2008. He has been with the Communication Systems Group at University of Zurich since 2005, where he works currently as a postdoc researcher. His areas of expertise include AAA architectures, IP flow accounting, network management, and mobile telecommunication and IP networks.

PhD project description

The primary goal of this thesis is to develop an accounting architecture, enabling the dynamic configuration of the accounting process in a heterogeneous, mobile, multi-service network environment. Since accounting can have various objectives, the accounting architecture has to support a tailored accounting configuration according to these objectives. This will enable a flexible accounting process according to user profiles, service profiles, or diverse charging schemes and will reduce the accounting overhead, resulting from metering effort and accounting record transfer and storage.

This thesis has the following objectives:

  • Development of a role model for a multi-service, multi-provider, mobile network environment, identifying participating entities, accounting and charging related relationships, and interactions.
  • Development of a service model, which classifies services into access, transport, and application services and introduces the concept of a user-level service, allowing the hierarchical combination of access, transport, and application services.
  • Development of an accounting model, identifying key functional accounting components and their interactions, where mobility, multi-service, and multi-domain support are considered in detail.
  • Development of a generic accounting configuration architecture for a multi-domain, mobile environment, enabling a user and service-specific accounting configuration for composed services. Specification of an accounting configuration protocol as an extension to the Diameter protocol.
  • Prototypical implementation and evaluation of the architecture.
