All the packets passing through a network facility, e.g. router or switch, must share the limited resources. These shared resources include the available bandwidth of linking channels, CPUs and the buffers. Packets will differently delay if multiple heterogeneous communication channels are used. Present paper aims at overcoming this delay problem for delivering data in case of existence of a number of heterogeneous linking channels by proposing the packet forwarding mechanism Optimized Load Balancing. Also numerical results are obtained for Optimized Load Balancing mechanism that convince of the improvement of delays for proposed mechanism with multiple network links approach.","PeriodicalId":210748,"journal":{"name":"International Journal of Open Problems in Computer Science and Mathematics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128530120","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}

The present paper proposes a states graph generation from a reduced dPTPN model in order to deal with the scheduling analysis. Based on hierarchical modeling, the present model presents only the interaction between all RTS components and excluding their internal behavior. According to this reduction, a new denition of state is given. Hence, all reachable states and edges connecting between them are generated to show a prediction of the RTS scheduling. Thus, the resulting graph gives birth to an open research area in the purpose of checking its properties and deducing the schedulability.","PeriodicalId":210748,"journal":{"name":"International Journal of Open Problems in Computer Science and Mathematics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126107858","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}
