As a typical complex embedded computer control system, computer numerical control(CNC) system development is confronted with a great challenge because of its specific requirements as well as some recent development trends such as ever more complex products while at lower prices and shorter develop cycle. In this paper, a model driven methodology for CNC system design and development is presented,...
One difficulty in distance teaching is how to determine static and dynamic abilities of student, which teaching strategies can be adjusted according to individual differences and learning effect can be improved. This paper proposes a structured student learning model. Teaching system can teach students according to their aptitude based on this model. The distance teaching adaptability can be achieved...
A component-based model integration approach for the embedded computer control system (ECS) development is proposed in this paper. The three-layer architecture for modeling, verification as well as implementation is described. Model strategies such as multi-aspect & multi-view description method, DSML (domain specific modeling language) & FML(formal modeling language) description method as...
With the rapid development of network scale, the current SNMP network management model has not been able to meet requirements. Therefore, a new kind of management system and strategy must be provided to enhance the reliability and performance of the network management. This article discusses problems existed in traditional network and analyses the management system structure and management mechanism...
Active network is a new framework where it not only forwards packets, but also performs customized computation on packets. It provides a programmable interface to users where users dynamically inject services through nodes. This paper discusses the forwarding model and mechanism of message based on active network management model, analyzes the structure and characteristics of this model, and studies...
Modern network processor systems require the ability to adapt their processing capabilities at runtime to changes in network traffic. Traditionally, network processor applications have been optimized for a single static workload scenario, but recently several approaches for run-time adaptation have been proposed. Comparing these approaches and developing novel run-time support algorithms is difficult...
