The goal was to make a rather simple experiment, and study how difficult it was to carry out correctly. This means it had to be correct, reproducible and efficient.\u0000 The paper shows that despite the precautions taken, many parameters that could have an effect on the result were at first overlooked. It also shows that benchmarking plays a key role on making an experiment correct and reproducible. The process is in the end extremely tedious, and stresses the need for new tools to help users.\u0000 The contribution of this work is to present a methodology to get correct results on grid architecture, to identify relevant problems and to propose an infrastructure that answers part of the problems encountered during experiments. Additionally, pieces of this infrastructure have been built and are also presented.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114486340","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}

Resources are managed by resource managers (c.f. a queuing system of a computing center), and a user can use them while they are allocated to the user. To provide a stable service using \"resources\" connected to a wide area network, network itself should be also considered as a \"resource\" and bandwidth should be allocated to users appropriately. Resource is provided to a user or upper layer middleware by a resource manager. Therefore, to realize \"network as a resource\", bandwidth of network should be managed by a network resource manager, and an interface to provide resource service to users or middleware is required. National Institute of Advanced Industrial Science and Technologies (AIST), KDDI R&D Laboratories, NTT and National Institute of Information and Communications Technology (NICT) are promoting collaborative project, called G-lambda, to establish such a standard interface, which is called GNS-WSI (Grid Network Service-Web Services Interface).

There is thus a need for a dynamic negotiation protocol for the efficient support of heterogeneous services and pricing strategies that will exist in the Grid. We have proposed novel augmentations to existing service negotiation protocols in the areas of scalability, flexibility, support for distinct services and negotiation with several service providers simultaneously. The proposed autonomous negotiation protocol is based on a distributed multiagent framework creating an open market for Grid services. We have explained the consolidated protocol for Intra-domain and Inter-domain cases using specific scenarios that involve bi-lateral bargaining. Furthermore, the usefulness of our algorithm is exhibited by a categorical comparison made between the attributes of our protocol with the corresponding attributes of other key protocols in literature. In addition, our work is aligned with the FIPA and OGSA initiative.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116219218","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}

Among other things, the survey results have revealed the diversity of Grid traffic, suggesting that there is more to Grid traffic than just transfers of huge bulks.

Since current Grid metaschedulers operate in a centralized fashion and thus are single points of failure, we present a distributed meta-scheduler for a service-oriented Grid environment based on peer-to-peer (P2P) networking techniques and ant colony optimization algorithms adapted to a P2P network. In the proposed approach, the meta-scheduling process provides automatic load balancing, is completely decentralized, fault tolerant, scalable, and does not require complex administration. Experimental results demonstrate that scheduling decisions are made quickly and lead to a good balance of the computational load.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"07 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131202178","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}

Accordingly, the bottleneck exists at the last mile from the Grid backbone to those mobile terminals where wireless environment places limitations on the rate and amount of communication. Point-to-multipoint (PTM) communication is an effective solution to this limitation. This paper develops the PTM parallel channels content organization mechanism to support timely and reliable access to the common interested information on the Mobile Grid, which has great practical value in the mobile IPTV application scenario. Moreover, we systemically study the parallel channels content organization for non-concurrent and concurrent content retrieval, and then contribute better content organization and retrieving algorithms which fully utilized the concurrent parallel content retrieval capability. The algorithms proposed could deliver information in a very high-performance way to larger user groups so as to achieve shorter response time and less network latency, both for the source-side and for the destination-side. We demonstrate the effectiveness of related mechanisms using a number of examples and some performance experiments.","PeriodicalId":380761,"journal":{"name":"Networks for Grid Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133553862","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}
