Thank you for your extensive reply. I still have a question ! A colleague of mine has made some experiments with the ns simulator and she says that she uses a buffer of 25000 bytes. How do i configure it in the router ? Not all the packtes have the same size, so how do i set a 25k buffer on...

When i'm apllying the hold-queue command on an interface, what are the units of the number i apply ? bytes ? buffers ? packets ? By default, my 1600 interfaces have 40 on output and 75 on input ? But what this numbres mean ? Thank you.

In a serial interface you can adjust the clock rate to some predefined values, and so you are in fact changing the bandwith of the link. Beware of the "bandwith" command, which is only for informational purposes only, for example, when you are apllying service-policies to an...

Thank you all for your most valueable help. I'm happy to say that i've already found a solution for my problem ! In each thread i created a non-static variable and i passed it's address as an argument to the function that was shared between all the threads. In this way, i'm able to store the...

In all the documentation that i have found i saw that the "priority" keyword in a context like this one: Router(config-pmap-c)# priority xxx Kbps would specifie the guaranteed allowed bandwith for priority traffic. My question is: What kind of priority traffic is this? Can i...

Hi there. I have a custom queue list applied on a serial interface and it looks like this (it might seem a little bit weird, but this is for a research project, not real world !): access-list 101 permit udp any any precedence internet access-list 102 permit udp any any tos min-monetary-cost...

I got this problem: I need to preserve the value of a variable between the executions of the same function. I know this can be done with the "static" keyword. But the problem is that this function is called by different threads. In this case the use of the keyword "static&quot...

Tanx my friend.. It really helped me out !

Hi there... i have a little theoretics question. I have a DCE/DTE cable connecting two 2600 Cisco routers. In the router with the DCE termination i have configured a clock rate of 500000. In theory, what is the available bandwith for this serial link ? a) 500 Kbps b) other ? I know this may...

I solved out my problem.. I use the command "queue-list 2 lowest-custom 2" and the queue 1 gets priority over the other queues.. thank you all for your suport (till now only phil)

I'm starting to have a little hope on this... I read in "IP Quality Of Service" (page 100) from Cisco Press that it is possible to prioritize some of the queues in a custom queueing mechanism if we setup a so called lowest-custom queue. Till now i haven't found how to do that.. Tanx...

Tanx Phil.. i'm in real trouble... my teacher is putting a lot of pressure on me ... anybody out there with a brilliant solution please report.. thank you all

Hi there.. I'm doing a research project at the university and i'm stuck with a problem.. any help would be of great importance. My problem: I have 3 classes of traffic and i want to use the custom queueing mechanism in a serial interface. This represents no problem but one off those classes...
