    Dear Colleagues: Following, the success of last year's Work In Progress (WIP) Sessions during RTSS'96, I am pleased to continue that tradition by presenting you 10 excellent WIP reports for RTSS'97. The prime purpose ...
  • Shudong, Jin; Bestavros, Azer; Iyengar, Arun (Boston University Computer Science Department, 2001-10)
    Internet streaming applications are adversely affected by network conditions such as high packet loss rates and long delays. This paper aims at mitigating such effects by leveraging the availability of client-side caching ...
  • Yoon, Jaehee; Bestavros, Azer; Matta, Ibrahim (Boston University Computer Science Department, 1999-09-15)
    An increasing number of applications, such as distributed interactive simulation, live auctions, distributed games and collaborative systems, require the network to provide a reliable multicast service. This service enables ...
  • Bestavros, Azer; Katagai, Naomi; Londoño, Jorge M. (Boston University Computer Science Department, 1998-05)
    In this paper we examine a number of admission control and scheduling protocols for high-performance web servers based on a 2-phase policy for serving HTTP requests. The first "registration" phase involves establishing the ...
  • Bestavros, Azer; Nagy, Sue (Boston University Computer Science Department, 1996-01-15)
    We propose and evaluate an admission control paradigm for RTDBS, in which a transaction is submitted to the system as a pair of processes: a primary task, and a recovery block. The execution requirements of the primary ...

(Boston University Computer Science Department, 1996-01-15)
    A Real-Time DataBase System (RTDBS) can be viewed as an amalgamation of a conventional DataBase Management System (DBMS) and a real-time system. Like a DBMS, it has to process transactions and guarantee ACID database ...
  • Hartmann, Olivier; Bestavros, Azer (Boston University Computer Science Department, 1998-01-05)
    In this paper we present an extension of the TCP stack that allows a sequence of TCP connections between the same machines to share the congestion window. Our Linux implementation of this scenario shows significant improvement ...
  • Bestavros, Azer; Makarechian, Mohammad (Boston University Computer Science Department, 1993-12)
    This paper describes a prototype implementation of a Distributed File System (DFS) based on the Adaptive Information Dispersal Algorithm (AIDA). Using AIDA, a file block is encoded and dispersed into smaller blocks stored ...
  • Bestavros, Azer (Boston University Computer Science Department, 1996-01-05)
    The proliferation of mobile computers and wireless networks requires the design of future distributed real-time applications to recognize and deal with the significant asymmetry between downstream and upstream communication ...
  • Morcos, Hany; Bestavros, Azer; Matta, Ibrahim (Boston University Computer Science Department, 2006-10-04)
    Personal communication devices are increasingly equipped with sensors for passive monitoring of encounters and surroundings. We envision the emergence of services that enable a community of mobile users carrying such ...
  • Morcos, Hany; Bestavros, Azer; Matta, Ibrahim (Boston University Computer Science Department, 2006-04-14)
    Abstract—Personal communication devices are increasingly being equipped with sensors that are able to passively collect information from their surroundings – information that could be stored in fairly small local caches. ...
  • Sweha, Raymond; Bestavros, Azer; Byers, John (Boston University Computer Science Department, 2009-02-10)
    This paper proposes the use of in-network caches (which we call Angels) to reduce the Minimum Distribution Time (MDT) of a file from a seeder – a node that possesses the file – to a set of leechers – nodes who are interested ...
  • Sweha, Raymond; Ishakian, Vatche; Bestavros, Azer (CS Department, Boston University, 2010-08-12)
    Leveraging client upload capacity through peer-assisted content distribution was shown to decrease the load on content providers, while also improving average distribution times. These benefits, however, are limited by the ...
  • Bestavros, Azer; Carter, Robert L.; Crovella, Mark E.; Cunha, Carlos R.; Heddaya, Abdelsalam; Mirdad, Sulaiman A. (Boston University Computer Science Department, 1995-01-15)
    With the increasing demand for document transfer services such as the World Wide Web comes a need for better resource management to reduce the latency of documents in these systems. To address this need, we analyze the ...
  • Bradley, Adam D.; Bestavros, Azer (Boston University Computer Science Department, 2001-10-30)
    With web caching and cache-related services like CDNs and edge services playing an increasingly significant role in the modern internet, the problem of the weak consistency and coherence provisions in current web protocols ...

  • Jin, Shudong; Bestavros, Azer (Boston University Computer Science Department, 2002)
    We consider the problem of delivering popular streaming media to a large number of asynchronous clients. We propose and evaluate a cache-and-relay end-system multicast approach, whereby a client joining a multicast session ...
  • Laoutaris, Nikolaos; Zervas, Georgios; Bestavros, Azer; Kollios, George (Boston University Computer Science Department, 2006-07-14)
    In many networked applications, independent caching agents cooperate by servicing each other's miss streams, without revealing the operational details of the caching mechanisms they employ. Inference of such details could ...
  • Barford, Paul; Bestavros, Azer; Bradley, Adam; Crovella, Mark (Boston University Computer Science Department, 1998-12-04)
    Understanding the nature of the workloads and system demands created by users of the World Wide Web is crucial to properly designing and provisioning Web services. Previous measurements of Web client workloads have been ...
