QoS on Specific IP's Ranges

Answered Question

User Badges:

Can we take a DIA Internet connection coming in and break it apart so that specific ip ranges can receive certain level of traffic or splice out 4mb of internet traffic to those ranges?


How can this be done?

You are correct in that inbound traffic queuing would really need to be done at the ISP end of the link.


You could set your end of the link to police traffic based upon source IP address which would cause non-conforming traffic to be dropped.


Assuming the applications use TCP this would cause the senders to slow down leaving more bandwidth for the traffic that you want the link available for.


Have a look at this link for more information.

- Confgure ACL that mathces those IPs as source IP.

- Create class-map that matches that ACL.

- Create policy-map, use class-map from above and configure shaping/bandwidth on there.


something like:


ip access-list extended ip-range

permit ip host 1.1.1.1 any


class-map match-all ip-range-class

match access-group name ip-range


policy-map shape

class ip-range-class

bandwidth 4096

class class-default

fair-queue


For inbound traffic from service provider, your provider will have to provide some kind of QoS offering.

Is this suggestion only for outbound traffic from my network?


Correct.


So inbound we have to be done on the side of the DIA provider?
