| dc.title | A model to provide better performance and fault tolerance for small-size distributed systems | en_US |
| dcterms.abstract | The proposed model can provide better performance and fault tolerance to distributed systems of reasonable sizes. Better performance is achieved by load balancing and fault tolerance through duplicating and relocating the essential services. The name manager in the model allocates a service request to one of the idle distributed servers according to the current workload situations registered in the binding table or clearing house. When the server exports its service(s) to the name manager, it may complete donate all their rights of use. With these rights, the name manager can duplicate, relocate, or even recompile the donated service. The capabilities of duplication and relocation are essential for the name manager to play the role of load balancing. The motivation of the project comes from the fact that there is no de facto standard that can provide satisfactory load balancing and fault tolerance to small distributed system as manifested by the shortcomings of the DCE (distributed computing environment) supported by many vendors. The proposed model was partially verified by using Coloured Petrinet because it is available in the Department of Computing. The verification was sequential because it was difficult to set up the Petrinet environment for verification of parallelism. The experience with the project has indicated that the proposed model has derived insights for ways to achieve better performance and fault tolerance. Even the DCE architecture should migrate towards the direction as highlighted by the proposed model. | en_US |
