QoS for One Drive Download Traffic

[Ciscoaclara]

Hello,

We have read alot about Qos using NBAR. I wanted to see if we were taking the correct approach. Here is our situation:

We have a need to manage download traffic from One Drive to a location where we dont have ample amounts of bandwidth (working on upgrading).

We have been looking at Cisco's NBAR solution to manage this bandwidth issue. Here is the approach we are looking to take:

1.) Our Cisco Router (ISR 3925) we would enable NBAR with the following command on the interface facing our edge

conf t

interface gig 0/0

ip nbar protocol-discovery

2.) We would then create a Class map matching URLs. I have only included a few but i'm sure there is more

class-map match-any ONE_DRIVE

 match protocol http host "onedrive.com"
 match protocol http url "*.onedrive.com"
 match protocol http host "onedrive.live.com"
 match protocol http url "*.onedrive.live.com"

3.) Create a Policy Map with these parameters:

policy-map ONE_DRIVE

class ONE_DRIVE

bandwidth 20000 percent 20

4.) Apply policy map to internet facing interface

conf t

interface gig 0.0

service-policy input ONE_DRIVE

Are we taking the correct approach to this? Is there anything missing?

Hi,

You should first run a benchmark to see how the router identifies/classifies  ONE Drive traffic. Enable NBAR, run for a week or so, evaluate results to ensure correct classification and the configure your policy.

Thanks

You're trying to manage ingress traffic?

If so, you can apply a policer to it, but it generally doesn't work as well as desired. The ingress policer will very exactly manage bandwidth beyond your policer, but the link upstream of the policer can often suffer much.

Policing very much lower than you really desire will often keep the policed traffic from causing issues against other traffic, but, of course, you obtain a very low transfer rate for that traffic.

Besides looking into obtaining more bandwidth, you could ask your provider whether they would implement QoS on their end of the link (unlikely they will) or look into obtaining a 3rd party bandwidth management device.
