The ATLAS DDM accounting and Storage Usage Service

Federated Accounting Management System Architecture for Multimedia Service Usage Management

Service consumers are increasingly becoming aware of QoS and service subscriptions. Service providers (SPs) are also recognizing the opportunity to generate revenue by bundling services in packages and providing them to customers. Standardization bodies have begun to address requirements of charging and usage accounting management as SPs are increasingly relying on them. Federated accounting ma...

Scalable Usage Based Internet Accounting

In this paper we present a novel scalable accounting infrastructure to support charging for network usage and Quality of Service (QoS) in an Internet context. Measurement and accounting are two core processes of a charging mechanism that make heavy demand on resources. They reduce the resource available for the core processes of the network i.e. routing and forwarding packets. Increasing the pr...

Challenging Dropbox: The Adoption and Usage of New Cloud Storage Service "sciebo" at German Universities

As reported at EUNIS 2015, a large academic cloud storage service was launched in the beginning of 2015 by the majority of the public research and applied science universities in the German state of North Rhine-Westphalia (NRW) under the brand name “sciebo”. One year after the start, we will examine if the predictions made in the preparatory project phase on system performance and on service ad...

Real-time Service Accounting

Offering telematics services toward the end-users involves inter-domain real-time service provisioning, it therefore can also involves inter-domain real-time service accounting. Recognizing the increasing complexity of accounting services due to dynamic service usage behavior of the end-users, the paper addresses a way to first, decompose end-to-end service into accountable service components a...
