Abstract


A division - based distributed model using data locality in order to enhance the system performance and reliability of a distributed architecture . This architecture developed system has been proved in practice it has the advantage of generally distributed architecture . This before , focused on how to be a stand-alone system through reverse engineering methods designed to work on the architecture based on the division of the distributed system , and in this model , how in the network node before moving as an independent operator services division , in order to fully utilize the resources in order to improve the overall performance to [ 1,2 ] . This thesis is concerned with answering the following two questions : 1) How can better use the maximum efficiency of the previous existing research results to carry out such a model of software system design and practical activities ; 2 ) in this model under there what kind of problem . For the first question , this article use the method of design patterns , summed up the six design is based on the division of the mode of distributed systems , and together with the case studies to share design experience . Summarize the process of exposing the problems exist in this model , namely a lack of automation , and too dependent on the experience of the designers and administrators . So , to re-examine the architecture , this paper queuing model to analyze this architecture , automated methods . This paper found that the introduction of runtime dynamic partitioning can provide a solution to the problem ; in the old global load balancing based on the design of load balancing in two global and local levels , and joined in local resource use monitoring and feedback mechanisms . The simulation experiments show that this method has achieved very good results . In addition , this thesis also reviews the background of this distributed model , a detailed exposition of the parallel architecture , parallel database and load balancing aspects of the study of history and progress .
