Modeling and performance analysis of self-similar traffic have become an investigating hot topic in computer network. However, most of the studies have been focused on the estimation and influence of Hurst index, and ignored the other factors. In fact, some other factors have also important influence on network performance. In this paper, we make a thorough investigation on the influence factors to the network performance of self-similar traffic. Based on the buffer overflow probability derived by Norros, we firstly derive the formulas of average queuing length, queuing length variance, average delay, jitter and effective bandwidth. Then the influence of Hurst index, average arrival rate and variance coefficient of the traffic, along with the buffer size, utilization and the effective bandwidth of the system on the performances of self-similar traffic are investigated by means of simulation. The results reveal that all these factors have great influence on performance of the self-similar traffic and there is evidently time scale effect among them. Finally, the critical time scale is derived.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122222587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, owing to the existence of numerous communication participants from diverse organizations under an anonymous communication mechanism, the semantic heterogeneous issue in event-matching is fundamental. It affects the accuracy and comprehensiveness of event matching. But most existing content-based Pub/Sub systems are unable to support semantic. Therefore, in order to eliminate semantic heterogeneity happened on event matching, ontology is introduced in this paper. And considering the support of current content-based Pub/Sub systems infrastructure, we firstly put forward an approach to convert the original content-based data model to a new concept-based data model applying multidimensional-index(X tree) on a high level shared ontology library, and then raise relevant event-matching arithmetic using the cover of subscriptions information and matching order to accelerate the speed of matching. The experiment demonstrates that the arithmetic can be able to tackle the issue to some extent, meanwhile, increase the efficiency of event matching.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121210167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
