Poster: Compressing Flow Statistic Counters

With the continuous increase of Internet link speed and the number of flows, flow statistics has become a challenging task due to the demanding requirements on both memory size and memory bandwidth. In this paper, we propose a DIScount COunting (DISCO) method, which is designed for both flow size and flow bytes counting. For each incoming packet, DISCO increases the corresponding counter assign...

Leveraging Buffering Delay Estimation for Geolocation of Internet Hosts

Geolocation techniques aim at determining the geographic location of an Internet host based on its IP address. Currently, measurement-based geolocation techniques disregard the buffering delays that may be introduced at each hop along the path taken by probe packets. To fill this gap, we propose the GeoBuD (Geolocation using Buffering Delay estimation) approach. Although the network delay and t...

Experiences With The AT&T Internet Difference Engine

Unlike the numerous tools that exist for identifying when documents have changed, the AT&T Internet Diierence Engine (aide) identiies how they have changed. Also, because it archives past versions of pages, it provides the ability to see the evolution of pages being tracked, or to see changes across a set of related pages at the same points in time. Finally, Webguide (the Web Graphical User Int...

Optimal Current Meter Placement for Accurate Fault Location Purpose using Dynamic Time Warping

This paper presents a fault location technique for transmission lines with minimum current measurement. This algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. These current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...
