    • Caching Proxies: Limitations and Potentials 

      Abrams, Marc; Standridge, Charles R.; Abdulla, Ghaleb; Williams, Stephen; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1995-07-01), TR-95-12
      As the number of World-Wide Web users grow, so does the number of connections made to servers. This increases both network load and server load. Caching can reduce both loads by migrating copies of server files closer ...
    • Characterizing World Wide Web Queries 

      Abdulla, Ghaleb; Liu, Binzhang; Saad, Rani A.; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1997-02-01), TR-97-04
      Locating information on the WWW is a major activity for users, and Web Information Retrieval Systems (IRS) are becoming more important to support their endeavors. In this paper we characterize queries performed by Web ...
    • Modeling Correlated Proxy Web Traffic Using Fourier Analysis 

      Abdulla, Ghaleb; Nayfeh, Ali H.; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1997-11-01), TR-97-19
      We analyze the arrival rate of accesses to Web proxy caching servers. The results show that the data display strong periodic autocorrelation. The examined data sets show a consistent behavior in terms of having periods ...
    • Multimedia Traffic Analysis Using CHITRA95 

      Abrams, Marc; Williams, Stephen; Abdulla, Ghaleb; Patel, Shashin; Ribler, Randy; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1995-04-01), TR-95-05
      We describe how to investigate collections of trace data representing network delivery of multimedia information with CHITRA95, a tool that allows a user to visualize, query, statistically analyze and test, transform, and ...
    • NMFS: Network Multimedia File System Protocol 

      Patel, Sameer; Abdulla, Ghaleb; Abrams, Marc; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1992), TR-92-54
      We describe an on-going project to develop a Network Multimedia File System (NMFS) protocol. The protocol allows "transparent access of shared files across networks" as Sun's NFS protocol does, but attempts to meet a ...
    • Scaling the World-Wide Web 

      Abdulla, Ghaleb; Abrams, Marc; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1996-03-01), TR-96-06
    • Web Response Time and Proxy Caching 

      Liu, Binzhang; Abdulla, Ghaleb; Johnson, Tommy; Fox, Edward A. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1998-03-01), TR-98-07
      It is critical to understand WWW latency in order to design better HTTP protocols. In this paper we characterize Web response time and examine effects of proxy caching on response time. We show that at least a quarter of ...
    • WWW Proxy Traffic Characterization with Application to Caching 

      Abdulla, Ghaleb; Fox, Edward A.; Abrams, Marc; Williams, Stephen (Department of Computer Science, Virginia Polytechnic Institute & State University, 1997-02-01), TR-97-03
      Characterizing World Wide Web proxy traffic helps identify parameters that affect caching, capacity planning and simulation studies. In this paper we identify invariants that hold across a collection of ten traces ...
