CFTP: A Caching FTP Server
By analyzing the log les generated by the UK National Web Cache and by a number of origin FTP sites we provide evidence that an FTP proxy cache with knowledge of local (national) mirror sites could signiicantly reduce the amount of data that needs to be transferred across already overused networks. We then describe the design and implementation of CFTP, a caching FTP server, and report on its u...
متن کاملClient-Server Caching Revisited
The caching of data and/or locks at client workstations is an eeective technique for improving the performance of a client-server database system. This paper extends an earlier performance study of client-server caching in several ways. The rst is a re-examination of heuristics for deciding dynamically between propagating changes or invalidating remote copies of data pages in order to maintain ...
متن کاملA Server Caching Strategy in Client-Server Database Systems
A server caching strategy is proposed based on LRU, which uses the replaced page-id as the major information rather than the request page-id. So the server cache is seen to clients as a long virtual client LRU cache extended to the server. Since the replaced page-id is only sent to the server by piggybacking whenever a new page fetch request is sent, its additional overheads are minimal. We sho...
متن کاملPerformance Comparison of Server Load Distribution with FTP and HTTP
A Web server’s constraint on the number of pages it can serve simultaneously is largely because of two factors: the bandwidth available and the Web server itself. When a website is popular and if there is only one web server responding to all the incoming HTTP requests for a website it may be possible that the capacity of the web server may not be able to handle high volumes of incoming traffic...
متن کاملEmbedded Data Acquisition System Using an Internet Based FTP Server
In this paper we are presenting the internet based data acquisition system which will be comparatively low in cost and can be flexible to serve for different applications by connecting different modules. Key module in the system is embedded board which communicates via GPRS which eases it’s accessibility from any place in the world through a web server built into the board. Using FTP server rem...
