Please bring this to the attention of any FreeBSD or other *BSD programmers you know in the Santa Cruz area. Luigi Rizzo, from the University of Pisa but currently at UC Berkeley, is giving an informal working discussion regarding some of his FreeBSD related work on Wednesday, February 21 in Room 115 of the UCSC Baskin Engineering Building: ---------------------------------------------- dummynet: internal structure and applications In this informal talk we present the "dummynet" tool, a configurable link emulator which is part of FreeBSD and can be used for a variety of applications, ranging from simulating realistic testbeds for protocol evaluation to traffic shaping and bandwidth allocation for commercial providers. Dummynet has evolved over the past 3 years to include a number of different features. We will describe the functionalities currently supported by dummynet, present the internal structure of the tool, discuss some of its application, and interactively discuss possible new features. Preliminary work on performance issues in software based routers may also be discussed. ---------------------------------------------- This presentation is intended to be non-theoretical and directly useful to FreeBSD kernel/network hackers. The current schedule envisions two `relaxed working sessions' primarily of interest to system programmers or experienced network admins, followed by a general session at a time (5:30) when it should be relatively easy for those from off campus to park behind the Baskin building: 1) 2:00 - 3:00 * Dummynet. 2) 3:30 - 4:30 * PicoBSD. 3) 5:30 - 6:30 * General discussion/other topics. PicoBSD is a small version of FreeBSD that has been used in small embedded systems. For a summary of some of Luigi's FreeBSD work, please see: http://www.iet.unipi.it/~luigi/FreeBSD.html and: http://citeseer.nj.nec.com/rizzo97dummynet.html Other pages of interest: What is FreeBSD? www.freebsd.org What is PicoBSD? http://people.FreeBSD.org/~picobsd/ This talk is sponsored by the UCSC IEEE Student Chapter, a loose gaggle of local *BSD programmers, and the UCSC computer communication research group. ==================================================== Directions to the BASKIN ENGINEERING BUILDING. See: http://www.cse.ucsc.edu/general/find.html http://www.cse.ucsc.edu/general/map.gif On the above map, the Baskin Engineering Building is labeled "Applied Sciences". Slightly modified directions from these maps: To get to UCSC from the Bay area, take US 280 or CA 101 to US 880 or CA 17 south. Take CA 17 south to Santa Cruz, then CA 1 north to Bay St. Turn right on Bay which will take you to the base of campus. There is some metered parking on campus. However, you may want to purchase a day permit. In the Monterey Bay area, take CA 1 north or south to Santa Cruz and Bay St. CA 1 in Santa Cruz is also Mission Street. Once on campus, if you're planning to get a parking pass, you'll need to make two immediate right turns just past the information kiosk at the main campus entrance. To find the Baskin School of Engineering, proceed on up Coolidge Drive and follow the main road as it turns into McLaughlin Drive. At the stop sign between Applied Sciences (Baskin Engineering) and the Communications buildings, you'll want to turn right for the closest parking. This intersection has a stack of signs with no street name but with "Computer Center->" at the top. After 5:00 you can park without a parking permit in the large parking lot behind the Baskin Building (the parking lot is behind a large number of trailers). Room 115 is on the ground floor nearest the large construction site across McLaughlin drive. If you come during the afternoon, any non-student can buy an A parking permit for the day at the front Kiosk for $6 (prices went up). You may want to park in one of the remote parking lots. UCSC operates a shuttle service worthy of an international airport from these lots to the campus buildings.
