Traditional ESB is not efficient enough for dynamical composition; and do not have the coordinative distributed execution feature, which can provide both effective and rapid service composition. This paper proposes a Coordinative Service Bus based Execution Platform at the basis of service coordination and service bus. Through creating Execution Binding Map (EBM), the platform uses a method of pre-binding optimal services to improve efficiency of service selecting and invoking. In addition, it uses a method of Multi-level Request Scheduling with Feedback to ensure the overall efficiency of the platform and to reduce the possibility of failure of partial services.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128469255","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}

According to this situation, the link management is presented as an important issue. This paper proposes a multihomed terminal based Dynamic Link Management Algorithm (DLMA), and introduces the basic principles and implement procedure of the algorithm. Moreover, the DLMA is used to compare with request-based and quantum-based methods. DLMA is a terminal based link management algorithm which can allocate and release the link resource according to the user requirement. The advantage is to reduce the overhead of link operation while fulfilling the user demand. By the experiment analysis, we evaluate the effectiveness of the DLMA.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127777325","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}

We perform a time-scale modification (TSM) using a waveform similarity overlap-add (WSOLA) technique with gain control (GWSOLA) to reconstruct the audio signal of the lost frames.

The core idea of the strategy is that the users are classified into four groups in terms of users' relative location in the heterogeneous networks. Different strategy can be taken when the handovers are triggered in different regions. The objective is to satisfy the service requirement and maintaining an appropriate load balance in different regions. The performance of the handover strategy is evaluated through simulation analysis.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127092501","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}
