All: I''m trying to get RSVP running on a Linux machine. The machine is currently Fedora. I have read rfc 2205. Does anyone know where I can get the RSVP source code to install on the machine. Or does anyone know of some documentation that might help in doing this? Thanks, Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Does anyone on hear have any thoughts on the changes that would be nessary for KOM RSVP to use HTB rather than just CBQ and HFSC? Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Is there anyway to actually see packet stats or that packets are for sure going into a prio queue with TC? I can see all the HTB stats but the prio classes just list as being there...would like more information Basically I have the following setup DSMARK | HTB - (tcindex filter on TOS) | Prio (u32 filter on TOS) Thanks Jon Flechsenhaar Boeing WNW Team Network Services

All: I am tasked with creating an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.)

All: Does anyone know what the burst and cburst parameter do? My understanding so far: * I see a lot of different definitions on the web. It seems like burst is the number of bytes sent before serving other queues/classes. So if burst was 1000 bytes and class rate was 100kibit per second. It would send 1000 bytes each time the scheduler service that queue to a rate of 100 kbit per

All: I have been told that HTB_HYSTERESIS might have some effect on rate calculations. This file is usually in /usr/src/linux/net/sched/sch_htb.c. If I change this file I have to re-compile. I am not quite sure how to do this. Can someone list the steps necessary to re-compile or point me to a doc that explains how to do so. Thanks. Jon Flechsenhaar Boeing WNW Team Network Services

I want to limit pps (packets per second) not just bandwidth on the ingress side. I can do this using IP tables but I''m curious if there is a way to do this with TC. Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

You guys have expressed interest in CCNA training. What would be better for you guys. On-site training after work hours or during the wkend? The other option is after hours or wkend at a near by college. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

I can use DSMARK to mark on the Egress side. Is there a way to mark/change the DSCP value of an incoming packet on the ingress side? Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

all: I"m just trying to create a simple rsvp session to familiarize myself with the protocol. I don''t ever get a rsvp RESV message only PATH AND PATH TEAR messages. There is a timeout but i''m not sure whats causing it exactly. Can anyone shed some light on why? All the configs and output are below. Please let me know if you need more information. Thanks.

Hi. I just went thru reading all of the howto and have a working implementation of RSVP over UDP encapsulation that i would linke to test, made in Java. For this, I would like to use a Linux Box as a RSVP enabled router. However, I have tried and tried to make RSVP work on linux and failed. So I wonder what I am doing wrong. Basically, on the linux box what I am doing is turning

Have a few generic questions about Kom-RSVP 1.) 11:00:05.175 WARNING: timer system overloaded, deviation is 30.080 sec - what timer is this referring to? System time? 2.) What is the relationship between the CBQ class created for RSVP traffic and the CBQ parameter that is in RSVP.conf? - ex. ### cbq qdisc ### tc qdisc add dev eth0 root handle 1: cbq bandwidth 10mbit avpkt 1000 mpu 64

Hi! I am studying HTB. I used the topology showed below: 10.1.0.1 ------ 10.1.14.25 (eth1) / 192.168.10.10 (eth0) ----- 192.168.10.11 (host 1) (router) (host 2) All machines use Debian Etch. Has a Iptables masquerading rule to eth1 in the router machine . The NICs are 100 Mb/s. The host 1 has Apache 2 and a file with 670 MB (CD ISO image) to download. When I used

Greetings. I am trying to use ISI RSVP to make some layer3 reservations. My problem is that RSVP refuses to configure the queues with an "RNETLINK answers: invalid argument" error. Even if I try to setup the filter with tc command, I get the same error. I already tried to load all the modules necessary, rsvp and rsvp6 included, but I still got the same error. Can someone help me? Is the
