  • West, Rich; Zaroo, Puneet; Waldspurger, Carl; Zhang, Xiao (CS Department, Boston University, 2010-07-02)
    Modern chip-level multiprocessors (CMPs) contain multiple processor cores sharing a common last-level cache, memory interconnects, and other hardware resources. Workloads running on separate cores compete for these resources, ...
  • Epstein, Samuel; Matta, Ibrahim; Mattar, Karim (Boston University Computer Science Department, 2008-08-15)
    We present an online distributed algorithm, the Causation Logging Algorithm (CLA), in which Autonomous Systems (ASes) in the Internet individually report route oscillations/flaps they experience to a central Internet Routing ...
  • Lapets, Andrei; Lalwani, Prakash; Kfoury, Assaf (CS Department, Boston University, 2010-05-14)
    The usability of verification systems is becoming increasingly important, and the effective integration of ontologies of formal facts (definitions, propositions, and syntactic idioms) into machine verification systems will ...
  • Tsaoussidis, Vassilis; Matta, Ibrahim (Boston University Computer Science Department, 2001)
    We discuss the design principles of TCP within the context of heterogeneous wired/wireless networks and mobile networking. We identify three shortcomings in TCP's behavior: (i) the protocol's error detection mechanism, ...
  • Basu, Prithwish; Narayanan, Ashok; Ke, Wang; Little, Thomas D.C.; Bestavros, Azer (Boston University Computer Science Department, 1999-07-27)
    Dynamic service aggregation techniques can exploit skewed access popularity patterns to reduce the costs of building interactive VoD systems. These schemes seek to cluster and merge users into single streams by bridging ...
  • Sweha, Raymond (Computer Science Department, Boston University, 2013-02-08)
    Increasingly, content delivery solutions leverage client resources in exchange for service in a peer-to-peer (P2P) fashion. Such peer-assisted service paradigms promise significant infrastructure cost reduction, but suffer ...
  • Heddaya, Abdelsalam; Fahmy, Amr (Boston University Computer Science Department, 1994-12-05)
    Predictability -- the ability to foretell that an implementation will not violate a set of specified reliability and timeliness requirements -- is a crucial, highly desirable property of responsive embedded systems. This ...
  • Bestavros, Azer (Boston University Computer Science Department, 1994)
    Predictability — the ability to foretell that an implementation will not violate a set of specified reliability and timeliness requirements - is a crucial, highly desirable property of responsive embedded systems. This ...
  • Smaragdakis, Georgios (Boston University Computer Science Department, 2008)
    Overlay networks have been used for adding and enhancing functionality to the end-users without requiring modifications in the Internet core mechanisms. Overlay networks have been used for a variety of popular applications ...
  • Yuan, Quan; Thangali, Ashwin; Ablavsky, Vitaly; Sclaroff, Stan (Boston University Computer Science Department, 2007)
    Object detection can be challenging when the object class exhibits large variations. One commonly-used strategy is to first partition the space of possible object variations and then train separate classifiers for each ...
  • Brova, George (Computer Science Department, Boston University, 2012-05-09)
    Existing models of information diffusion assume that peer influence is the main reason of the observed propagation patterns. This work examines the role of authority pressure on the observed information cascades. We model ...
  • Almeida, Virgílio; de Almeida, Jussara; Murta, Cristina (Boston University Computer Science Department, 1996-08-05)
    This paper addresses the problem of analyzing performance of WWW servers. The web has experienced a phenomenal growth and has become the most popular Internet application. As a consequence of its large popularity, the ...
  • Barford, Paul; Crovella, Mark (Boston University Computer Science Department, 1998-10-23)
    Version 1.1 of the Hyper Text Transfer Protocol (HTTP) was principally developed as a means for reducing both document transfer latency and network traffic. The rationale for the performance enhancements in HTTP/1.1 is ...
  • Bestavros, Azer; Braoudakis, Spyridon; Panagos, Euthimios (Boston University Computer Science Department, 1993-02-05)
    Speculative Concurrency Control (SCC) [Best92a] is a new concurrency control approach especially suited for real-time database applications. It relies on the use of redundancy to ensure that serializable schedules are ...
  • Thangali, Ashwin; Sclaroff, Stan (Boston University Computer Science Department, 2004-11-02)
    A novel technique to detect and localize periodic movements in video is presented. The distinctive feature of the technique is that it requires neither feature tracking nor object segmentation. Intensity patterns along ...
  • Harfoush, Khaled; Bestavros, Azer; Byers, John (Boston University Computer Science Department, 2002)
    Growing interest in inference and prediction of network characteristics is justified by its importance for a variety of network-aware applications. One widely adopted strategy to characterize network conditions relies on ...
  • Sclaroff, Stan; Pentland, Alex (Boston University Computer Science Department, 1994-11)
    Nonrigid motion can be described as morphing or blending between extremal shapes, e.g., heart motion can be described as transitioning between the systole and diastole states. Using physically-based modeling techniques, ...
  • Baruah, Sanjoy; Bestavros, Azer (Boston University Computer Science Department, 1996-08-22)
    The design of programs for broadcast disks which incorporate real-time and fault-tolerance requirements is considered. A generalized model for real-time fault-tolerant broadcast disks is defined. It is shown that designing ...
  • Esposito, Flavio (Computer Science Department, Boston University, 2013-10-20)
    Network virtualization is a technology that enables multiple virtual instances to coexist on a common physical network infrastructure. This paradigm fostered new business models, allowing infrastructure providers to lease ...
  • Jin, Shudong; Bestavros, Azer (Boston University Computer Science Department, 1999-08-21)
    Web caching aims to reduce network traffic, server load, and user-perceived retrieval delays by replicating "popular" content on proxy caches that are strategically placed within the network. While key to effective cache ...
