QoS for video over mpls

*** Moved from Video Over IP group ****

All,

I'm about to set up a video  conference system between branches over our provider's mpls network. It  would look like the following:

video equip (10.5.5.5) -> (fa0/1) branch  (s0/0) -> provider -> (s0/0) corp (fa0/1) -> video equipment  (10.7.7.7)

QoS  has been applied at both ends (Branch/Corp) from the provider's  viewpoint. I need to know how the best way to handle qos would be. Below  is what I'm thinking:

Branch router:

access-list 20 permit host 10.5.5.5


class  Inbound

match ip address 20

class outbound

match ip dscp af41

policy-map  Inbound

set dscp af41

policy-map Outbound

bandwidth 512k

int fa0/1

service-policy  input Inbound

int  S0/0

service-policy output Outbound

This is all from my head above, so I  figure the syntax isn't 100% correct. My goal is to ensure that the  incoming traffic from the device is marked with AF41. On the Corp side, I  would have another policy map INBOUND that states to match on the AF41  and then I'm assuming that I would set my bandwidth statements on  Outbound on the Corp fa0/1 side? That's where I'm confused.

Thanks!

John

Re: QoS for video over mpls

There is no need to match inbound at the CORP side.

You simply apply the same syntax but on the return traffic from the CORP side.

For instance

access-list 20 permit host 10.7.7.7

class  Inbound

match ip address 20

class outbound

match ip  dscp af41

policy-map   Inbound

set dscp af41

policy-map Outbound

bandwidth 512k

int fa0/1

service-policy   input Inbound

int   S0/0

service-policy output Outbound
