The ftp server at Whistle is not yet updated but the new tar files are available from http://www.freebsd.org/~julian/ (via links) There are 2 tarballs, one for 3.x and one for -current (4.0). I have only briefly tested these, though we use this code heavily in a 3.1++ system in production. Specifically I have only tested them in kld usage and have not yet run them in a 'compiled in' setup, (though I can't see why it would be different). The README is still valid though the names of the tarfiles are slightly different (tar xvf netgraph.tar.3.X or netgraph.tar.4.0 vs tar xvf netgraph.tar) As before this give a working (and tested by MCI!) frame relay implementation (among other nice tricks). julian On Fri, 3 Sep 1999, Kurakin Roman wrote: > Hi, > > I have problem with compiling netgraph version 8.

Now, i would like to introduce it into the FreeBSD-net community, for beta testing. (Hopefully, I'll contribute the code to the current...) [Features] - a process-oriented software packet shaper, on which you can limit network output of any process - very little packet classification overhead and almost no impact on max throughput - provide bandwidth control without hardware, e.g. ATM card, or shaper boxes - works with ALTQ (tested on FreeBSD 2.2.8) - shipped with useful bandwidth management applications for easy control over network output - netnice command (works similarly to nice and renice) % netnice 128Kbyte/sec 123 - Enhanced sh (sh with bandwidth control feature) (maybe useful for scripting) % ftp www.foo.bar @512KBps % rcp /var/log/access.log archive:/var/hoge @32KBps - Enhanced inetd (bandwidth control over network services) %cat /etc/inetd.conf ftp ... /usr/local/libexec/ftpd ftpd -l telnet ... /usr/libexec/telnetd telnetd @32K/sec shell ... /usr/libexec/rshd rshd @32K/sec %inetd -c 10 @512KB/sec (In this case, telnet and rsh sessions will have 32KB each, and ftp sessions will be granted the rest of the available bandwidth fairly.) - bandwidth control module for Apache (mod_netnice.c) [Information] http://www.cs.pitt.edu/~taka/software/netnice.html mail:taka@cs.pitt.edu I believe that this is quite useful option to control LAN bandwidth for sites suffering from huge volume of traffic for log file and netnews transfer. It's simple, and you can have control over them without any hardware assistance.

As indicated in my source code, the work greatly owes to your Dummynet implementation, particularly, your packet preemption mechanism. I wish to thank you and GPL. They shares: - Packet enqueue/dequeue mechanism in ip_output(). The differences are: - Packet scheduler packet is independently scheduled by timeout(), not by periodical function. - Packet classifier The code utilises: in_pcblookuphash() for option NETNICE tag on mbuf for option NETNICE + NETNICE_TAG - Input meter - Modification in struct proc Regarding more complete implementation summary, i'm currently working on several evaluation papers which might be helpful. It will be available within a few weeks, and I'll send you a copy when ready. So could you kindly give me a little time to prepare?
