Smart file objects
Jon Weissman · 1999
This paper describes o new scheme for remote file access called Smart File Objects (SFO).The SF0 is an object-oriented application-specific file access paradigm designed to attack the bottleneck imposed by high Iotency low bandwidth networks such (IS wide-area and wireless networks.The SF0 uses application and network inform&on to adaptively prefetch needed data in pnmllel with the aecurion of the application.The SF0 con offer additional advantages such (IS non-blocking I/O, bulk I/O, improved& access APIs, and increased relinbiliry We describe the SF0 concept, a prototype implementation in the Mentat system, and the results obtained with o distributed gene sequence application running across the Internet and vBNS.The results show the P otential of the SF0 opprooch to improve application performance.1.
