  • Effectiveness of Loss labeling in Improving TCP Performance in Wired/Wireless Networks
    Barman, Dhiman; Matta, Ibrahim (Boston University Computer Science Department, 2002)
    The current congestion-oriented design of TCP hinders its ability to perform well in hybrid wireless/wired networks. We propose a new improvement on TCP NewReno (NewReno-FF) using a new loss labeling technique to discriminate ...
  • Efficiently and Fairly Allocating Bandwidth at a Highly Congested Link
    Wang, Tao; Matta, Ibrahim; Bestavros, Azer (Boston University Computer Science Department, 2003-12-02)
    We consider the problem of efficiently and fairly allocating bandwidth at a highly congested link to a diverse set of flows, including TCP flows with various Round Trip Times (RTT), non-TCP-friendly flows such as ...
  • Exploiting Redundancy for Timeliness in TCP Boston
    Bestavros, Azer; Kim, Gitae (Boston University Computer Science Department, 1997-01-24)
    While ATM bandwidth-reservation techniques are able to offer the guarantees necessary for the delivery of real-time streams in many applications (e.g. live audio and video), they suffer from many disadvantages that make ...
  • Fine-Grained Layered Multicast
    Byers, John; Luby, Michael; Mitzenmacher, Michael (Boston University Computer Science Department, 2000-12-15)
    Traditional approaches to receiver-driven layered multicast have advocated the benefits of cumulative layering, which can enable coarse-grained congestion control that complies with TCP-friendliness equations over large ...
  • How does TCP generate Pseudo-self-similarity?
    Guo, Liang; Crovella, Mark; Matta, Ibrahim (Boston University Computer Science Department, 2001)
    Long-range dependence has been observed in many recent Internet traffic measurements. In addition, some recent studies have shown that under certain network conditions, TCP itself can produce traffic that exhibits dependence ...
  • How Well Can TCP Infer Network State?
    Barman, Dhiman; Matta, Ibrahim (Boston University Computer Science Department, 2003-05-16)
    The Transmission Control Protocol (TCP) has been the protocol of choice for many Internet applications requiring reliable connections. The design of TCP has been challenged by the extension of connections over wireless ...
  • Mapping Parallel Iterative Algorithms onto Workstation Networks
    Heddaya, Abdelsalam; Park, Kihong (Boston University Computer Science Department, 1994-02-07)
    For communication-intensive parallel applications, the maximum degree of concurrency achievable is limited by the communication throughput made available by the network. In previous work [HPS94], we showed experimentally ...
  • Open Issues on TCP for Mobile Computing
    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, ...
  • Providing Soft Bandwidth Guarantees Using Elastic TCP-based Tunnels
    Guirguis, Mina; Bestavros, Azer; Matta, Ibrahim; Riga, Niky; Diamant, Gali; Zhang, Yuting (Boston University Computer Science Department, 2003-12-02)
    The best-effort nature of the Internet poses a significant obstacle to the deployment of many applications that require guaranteed bandwidth. In this paper, we present a novel approach that enables two edge/border routers-which ...
  • A Spectrum of TCP-Friendly Window-Based Congestion Control Algorithms
    Jin, Shudong; Guo, Liang; Matta, Ibrahim; Bestavros, Azer (Boston University Computer Science Department, 2001-02-02)
    The increased diversity of Internet application requirements has spurred recent interests in transport protocols with flexible transmission controls. In window-based congestion control schemes, increase rules determine how ...
  • A Spectrum of TCP-friendly Window-Based Congestion Control Algorithms
    Jin, Shudong; Guo, Liang; Matta, Ibrahim; Bestavros, Azer (Boston University Computer Science Department, 2002-07)
    The increasing diversity of Internet application requirements has spurred recent interest in transport protocols with flexible transmission controls. In window-based congestion control schemes, increase rules determine how ...
  • TCP Boston: A Fragmentation-tolerant TCP Protocol for ATM Networks
    Bestavros, Azer; Kim, Gitae (Boston University Computer Science Department, 1996-07-15)
    The popularity of TCP/IP coupled with the premise of high speed communication using Asynchronous Transfer Mode (ATM) technology have prompted the network research community to propose a number of techniques to adapt TCP/IP ...
  • TCP Congestion Control and Heavy Tails
    Guo, Liang; Crovella, Mark; Matta, Ibrahim (Boston University Computer Science Department, 2000-07-03)
    Long-range dependence has been observed in many recent Internet traffic measurements. Previous studies have shown that there is a close relationship between heavy-tailed distribution of various traffic parameters and the ...
  • TCP-friendly SIMD Congestion Control and Its Convergence Behavior
    Jin, Shudong; Guo, Liang; Matta, Ibrahim; Bestavros, Azer (Boston University Computer Science Department, 2001-05-08)
    The increased diversity of Internet application requirements has spurred recent interests in flexible congestion control mechanisms. Window-based congestion control schemes use increase rules to probe available bandwidth, ...
  • The War Between Mice and Elephants
    Guo, Liang; Matta, Ibrahim (Boston University Computer Science Department, 2001)
    Recent measurement based studies reveal that most of the Internet connections are short in terms of the amount of traffic they carry (mice), while a small fraction of the connections are carrying a large portion of the ...
