May 1999 Newsletter of the

Front Range Unix Users Group

Cndnsd Vrsn: 4 PM Wednesday May 12 ACS Room 123 - Internet Traffic Measurement and Characterization


Internet Traffic Measurement and Characterization

The April meeting of the Front Range UNIX Users Group will be held at 4:00 P.M. on Wednesday May 12.

Evi Nemeth of the University of Colorado faculty will discuss the measurement and characterization of Internet traffic. MCI and CAIDA (Cooperative Association for Internet Data Analysis) have dedicated passive measurement boxes (OXcMONS's) on the MCI backbone and at key exchange points. Evi's talk will summarize the data seen on these networks including protocol distributions, packet sizes, flow characteristics, network and AS matrices, etc. She will also present data from an active measurement tool, skitter, that has been used to probe the Internet at about 30,000 key server hosts. FRUUG members will get a feel for the traffic on the Internet and changes in that traffic over the last couple of years.

Evi's FRUUG talks have always been full of interesting information, and this presentation will no doubt follow suit. Since this is an Internet-related talk, Addison-Wesley has provided us with some of their recent networking-related titles to give away at this meeting, so be sure to bring your business card for the drawing.

Meeting Location

This meeting will be in room 123 of the CU Academic Computing Center building at Arapahoe and Marine Streets in Boulder. Marine St intersects Arapahoe at 38th St; the Computing Center is on the southwest corner.

Our Last Meeting

At our April meeting, Joe VanAndel presented an overview of working with The Z Object Publishing Environment (ZOPE - to smoothly integrate Web front-ends with database back-ends. Joe demonstrated some sample programs that got us all really thinking about the new paradigms that this freely-available software presents. His viewgraphs are available on our previous meetings page.
