Concurrency control in distributed database systems
Distributed Database Systems (DDBS) may be defined as integrated database systems composed of autonomous local databases, geographically distributed and interconnected by a computer network.The purpose of this monograph is to present DDBS concurrency control algorithms and their related performance issues. The most recent results have been taken into consideration. A detailed analysis and selection of these results has been made so as to include those which will promote applications and progress in the field. The application of the methods and algorithms presented is not limited to DDBSs but

An Architecture for Performance Management of Multimedia Networks
A principal requirement for multimedia networks is the ability to allocate resources to network services with different quality-of-service demands. The objectives of achieving efficient resource utilization, providing quality-of-service guarantees, and adapting to changes in traffic statistics make performance management for multimedia networks a challenging endeavor. In this paper, we address the following questions: what is the respective role of the real-time control system, the performance management system, and the network operator, and how do they interact in order to achieve performance management objectives? We introduce an architecture for performance management, which is based on the idea of controlling network performance by tuning the resource control tasks in the traffic control system. The architecture is built around the L-E model, a generic system-level abstraction of a resource control task. We use a cockpit metaphor to explain how a network operator..
