altq-0.3.1 is now available from <http://www.csl.sony.co.jp/person/kjc/programs.html>; or <ftp://ftp.csl.sony.co.jp/pub/kjc/altq.tar.gz>; The release includes: alternate queueing support for FreeBSD-2.2.1R or 2.2.2R kernel CBQ and WFQ implementation tools for CBQ RSVP stubs for CBQ What's New since version 0.2: - merged LBNL cbq v2.0 featuring Top-Level link-sharing and Weighted-Round Robin. - FreeBSD-2.2.2R based. - better bandwidth allocation. - sppp (synchronous ppp) device support. - ATM multicast workaround for RSVP developpers. - many bug fixes. The idea behind this package is to provide better queueing schemes required to realize resource-sharing and quality of service. Currently, the only queueing scheme implemented in BSD Unix is the simple tail-drop FIFO queueing. The BSD Unix systems have no general method to implement alternate queueing schemes, which is the main obstacle to implement a new queueing scheme to BSD Unix. We have designed and implemented a generic alternate queueing framework for the BSD Unix systems, and ported Sun's CBQ onto this framework. The system can be used for resource reservation with the RSVP implementation from ISI. The preliminary performance test result is encouraging; our CBQ implementation is able to handle 100Mbps without noticeable overhead. The goals of this project are three-fold: - to provide a framework to implement better queueing schemes. - to provide a link-sharing test-bed for network operators. - to provide a traffic control kernel to the RSVP community. Send bug reports, suggestions, etc. to kjc@csl.sony.co.jp. --- Kenjiro Cho Sony Computer Science Laboratory, Inc.
