  • Small-time scaling behaviors of Internet backbone traffic: An empirical study 

    Zhang, Zhi-Li; Ribeiro, Vinay Joseph; Moon, Sue; Diot, Christophe (2003-04-20)
    We study the small-time (sub-seconds) scaling behaviors of Internet backbone traffic, based on traces collected from OC3/12/48 links in a tier-1 ISP. We observe that for a majority of these traces, the (second-order) scaling ...
  • PathChirp: Efficient Available Bandwidth Estimation for Network Paths 

    Ribeiro, Vinay Joseph; Riedi, Rudolf H.; Baraniuk, Richard G.; Navratil, Jiri; Cottrell, Les (2003-04-01)
    This paper presents <i>PathChirp</i>, a new active probing tool for estimating the available bandwidth on a communication network path. Based on the concept of "self-induced congestion," PathChirp features an exponential ...
  • Multifractal Cross-Traffic Estimation 

    Ribeiro, Vinay Joseph; Coates, Mark J.; Riedi, Rudolf H.; Sarvotham, Shriram; Hendricks, Brent; Baraniuk, Richard G. (2000-09-01)
    In this paper we develop a novel model-based technique, the Delphi algorithm, for inferring the instantaneous volume of competing cross-traffic across an end-to-end path. By using only end-to-end measurements, Delphi avoids ...
  • On the impact of variability on the buffer dynamics in IP networks 

    Joo, Youngmi; Ribeiro, Vinay Joseph; Feldmann, Anja; Gilbert, Anna; Willinger, Walter (1999-09-20)
    The main objective of this paper is to demonstrate in the context of a simple TCP/IP-based network that depending on the underlying assumptions about the inherent nature of the variability of network traffic, very different ...
  • A Multifractal Wavelet Model with Application to Network Traffic 

    Riedi, Rudolf H.; Crouse, Matthew; Ribeiro, Vinay Joseph; Baraniuk, Richard G. (1999-04-01)
    In this paper, we develop a new multiscale modeling framework for characterizing positive-valued data with long-range-dependent correlations (1/f noise). Using the Haar wavelet transform and a special multiplicative structure ...
