[LARTC] Dynamic bandwidth allocation ?

[LARTC] Dynamic bandwidth allocation ?

[Chandrashekhar Rane]

Dear All,

I have some doubt.

1) Is dynamic bandwidth allocation using tc is possible?
2) If yes, the how to implement it.
3) Is it possible to implement it with cbq.init script


Thanks in advance

regards
shekhar

What do you mean with "dynamic bandwidth allocation"?? Can you give an 
example.

Dear Mohan,

Thanks for the reply.

No, not time based.  
Consider a example, say i have a pipe of 10kbps.  I am dividing this
pipe in three classes with bandiwdth of 1kbps, 1.5kbps and 7.5kbps
respectively.

I am trying to implement this using CBQ with fw filter.

1kbps pipe i am allocating to fixed ip say 192.168.2.12 and 1.5kbps pipe
i am allocating to another ip say 192.168.2.22 and remaining 7.5kbps
pipe i am allocating to 192.168.2.0/24 network.   

If the person sitting on 192.168.2.12 or 192.168.2.22 is absent for the
day, then the bandwidth allocated to them should be release for the
other user.

How to achieve this objective. 

Waiting for a kind response from your side.

Dear Michael,

Thanks for the reply.

By dynamic allocation of bandwidth i mean to say, it should get
allocated according to the situation to the individual classes.

Consider a example, say i have a pipe of 10kbps.  I am dividing this
pipe in three classes with bandwidth of 1kbps, 1.5kbps and 7.5kbps
respectively.

I am trying to implement this using CBQ with fw filter.

1kbps pipe i am allocating to fixed ip say 192.168.2.12 and 1.5kbps pipe
i am allocating to another ip say 192.168.2.22 and remaining 7.5kbps
pipe i am allocating to 192.168.2.0/24 network.   

If the person sitting on 192.168.2.12 or 192.168.2.22 is absent for the
day, then the bandwidth allocated to them should be release for the
other user.

How to achieve this objective.

[Chandrashekhar Rane]

Dear Mohan,

Thanks for the reply.

If you send the URL for Stef Coene site, then it will be helpful for me.

One more thing.  If i used dialup modem for internet connection, then i
might not gate the same amount of bandwidth through out.  How to
overcome this situation.

What do you mean "smart htb/cbq setup"? Please, can
you detail with some examples?

Thanks,

R.

Very easy to do so.

bounded class of 10kbps
  3 child not-bounded classes :
    1kbps
    1.5 kbps
    7.5 kbps

3 fiters :
  filter 1 pust all 192.168.2.12 in 1 kbps class
  filter 2 pust all 192.168.2.22 in 1.5 kbps class
  filter 3 pust all 192.168.2.0/24 in 7.5 kbps class

And you are done.
If 1kbps class is not used, the bandwidth is distributed to the other class.
If you want this bandwidth allocated to the 1.5 kbps you can do this :

bounded class of 10kbps
  2 child not-bounded classes :
    2.5 kbps
      2 child not bounded classes :
        1 kbps
        1.5 kbps
    7.5 kbps

Re: [LARTC] Dynamic bandwidth allocation ?

[Chandrashekhar Rane]

Dear Stef,

Thanks for the reply.

But i want to implement the same for the dialup modem.  In which case i
don't have the fixed pipe of 10kbps.  Because some times dialup modem
gives me a bandwidth of 8kbps to 1kbps.  In this situation of varing
bandwidth how i implement the same.

Waiting for your reply.

shekhar

Re: [LARTC] Dynamic bandwidth allocation ?

[Chandrashekhar Rane]

Dear Serban,

Following is my setup.

I had a gateway machine with dialup modem and ethernet card.  I am
connected to local LAN using ethernet card.

Now i want to implement a CBQ + fw filter base bandwidth management
system.

The problem i faced is
1) I had a modem which is connected with my ISP for browsing,   
downloading etc..,
2) The modem doesn't give me fixed bandwidth.

Now how i assume a fixed pipe, or how i play with the bandwidth
available at particular moment so every user get a fair chance.

Suppose i want to create a three class.  say class A, class B, class C. 
Class A is for high priority traffic.
class B is for low priority traffic.
class C is for Some specific ports.

Then how i implement this with dynamic bandwidth which i rev, using
modem.

Thanks in advance.

shekhar
