Traditional peer-to-peer (P2P) applications such as Kazaa and Gnutella have been primarily used for sharing read-only files (such as mpegs and mp3s). This paper introduces two novel protocols, the End-to-End and Non End-to-End, for achieving mutual exclusion efficiently in dynamic P2P systems. The protocols are layered atop a distributed hash table (DHT), making them scalable and fault-tolerant. The burden of controlling access to the critical section is also evenly distributed among all the nodes in the network, making the protocols more distributed and easily adaptable to growing networks. Since the protocols are designed independent of any specific DHT implementation, they can be incorporated with any generic P2P DHT, depending on the application requirements. We present experiments comparing our implementations with existing mutual exclusion algorithms. The significant reduction in overall message overhead and better load-balancing mechanisms makes the proposed protocols very attractive in being used for current and future P2P and grid applications.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130088498","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}

As part of our larger effort at the University of Virginia to make the Windows platform a first-class participant in all aspects of grids, this paper describes our experiences and lessons learned while implementing GridFTP on the Microsoft .NET Framework. Our implementation not only supports major extensions of GridFTP v1, it also uniquely implements some features of GridFTP v2 and introduces a new transfer mode specifically designed for transfer of large collection of small files. Our measured performance is comparable to GT4 GridFTP on both single and parallel streams transfer and more efficient than GT4 GridFTP on directory tree transfer. We also identify issues specific to the .NET Framework/Windows platform with regard to security and we identify limitations of current GridFTP protocol. To our knowledge, the work described in this paper is the first comprehensive and evaluated implementation of GridFTP on .NET.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133604847","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, existing security firewalls often diminish the level of collaboration that is possible, and current grid middleware often assumes that there are no restrictions on the type of communication that is allowed. Accordingly, a number of collaborations have failed because the member sites have different and conflicting security policies. In this paper we present an architecture that facilitates inter-organization communication using existing grid middleware, without compromising the security policies in place at each of the participating sites. Our solutions are built on a number of standard secure communication protocols such as SSH and SOCKS. We call this architecture Remus, and will demonstrate its effectiveness using the Nimrod/G tools.","PeriodicalId":347929,"journal":{"name":"The 6th IEEE/ACM International Workshop on Grid Computing, 2005.","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132279943","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}
