Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

Hello, I am wondering if any of you knows how to add BR2684-rt nas interfaces into a Ethernet bridge, I know that brctl will work with BR2684-br, but not for BR2684-rt. Many thanks!

Anyone know if it''s possible to interleave two IP packets when using PPPoA and VC based lines? Can it be done with any PPPoE implementations? The goal is to reduce the delay when you have a high priority packet waiting, but a lower priority (large) packet already started going out ahead of this packet. I don''t want the overhead of much smaller MTU, which is the other way

Colleagues I am working in a Linux OS with R 2.6.2. I need to execute a telnet session to another Linux machine from R, perform some operations, then return to the original computer. When I am in an R session, this is easy to accomplish by typing: system("telnet -l username machinename") I am then asked for my password; once that is entered, I am connected to the remote

Hi, I use the patch (http://ace-host.stuart.id.au/russell/files/tc/tc-atm/) for accurate the packet scheduling on ATM/ADSL link and i think I''ve found a bug. I tried to write to the author but he didn''t answer me. I work on a Linux 2.6.17 with the iproute2-2.6.18-061002 package. I change the type of the cell_align char to short of the struct tc_ratespec in the file pkt_sched.h

...ctokens: 2886 ******************************************************** Why the ceil rate can''t be reached? rate 480008bit from 576000bit a little bit to huge difference. And besides this i''m using the overhead patch from Jesper Dangaard Brouer (iproute+htb) which takes the ATM+AAL5+SSCS Overhead into account. Can a slightly inaccurate clock has something todo with this? Another question: why "tc show class" prints the overhead and mpu value twice? And why is the first overhead value = 0? -- Markus Schulz

Hi I have the following problem: I''ve created qos script which shapes traffic on outgoing interface eth1.

Hello I have serious problem with zhone z-plex 10 the device sometimes get red alarm on some channel and then the device suddenly shutdown. I try to unplugged the power chord and plug again, but the device still didn't up. I have to wait for long time to get this device up again. How can i fix this problem, so i can get this device immediately? Eris Riswanto

I had originally mentioned this only to 2 people, which was Jordan K. Hubbard and Paul Henning-Kemp, but since I have received a lot of queries on this, I thought I might as well post it on the FreeBSD announce groups. Included below is a posting done on the Linux-atm mailing group, by Pragnesh Sampat. I have just adapted for FreeBSD. RV -------------------------- Announcement
