Upstream Rate Limiting - is it possible on 7200 HSSI?

I am looking for a cheaper option to a dedicated network management box like packeteer or WiseWan 401.

I would like to know if Upstream rate limiting is possible on a 7200 router. I have no access on our ISP's router so I need to apply something on my side.

Rate limiting on Protocols and IP addresses.

Any other solutions I may have overlooked/not found?

Thanks.

Hi,

Yes it is possible. Use "rate-limit output ..." command under the interface with its parameters.

Good luck

You can apply Committed Access Rate (CAR) based on an access-list :

rate-limit output access-group ....bandwidth and actions parameters...

Policing is too available with the Class Based Weighted Fair Queueing mechanism : you can set up different classes (based on different ACL) and apply on each a dedicated bandwitdh policy (rate limiting, shaping, ..)

class name

match access-group ..

policy-map name

class name

bandwidth policy ...

...

Generic Traffic Shapping is also available. You can create diffrent group (based on ACL) with different bandwidth parameters,

traffic-shape group 170 ...bandwidth parameters...

Re: Upstream Rate Limiting - is it possible on 7200 HSSI?

Thanks for the advice, but the thing I am trying to do is limit traffic coming towards me.

I have a salesman on my back trying to sell a device which he claims can do Upstream rate limiting.

I would like to know how he does it as I need rate-limiting on our satellite link urgently.

Unless I have a 'dam' upstream limiting the amount of information coming towards me I end up with some customers (IP range) chewing up the satellite link completely while others get very poor performance.

Personally I think the only way to do it is to use CAR on the ISP router (I have no access to that) or I put this 'device' (bandwidth manager) right next to the ISP router with a higher speed link to the ISP to give me space for dropped packets - packets which are at present being dropped at our router.
