Better way to dedicate internet link for Skype other than PBR My current solution for dedicate internet link for specific applications (eg. skype) is to use PBR with static destination of Skype servers IP addresses. But unfortunately IP address may change/add, and we have to manually configure them in PBR. So I want to think for another way to do this solution. One I can think of is to use some DPI marking DSCP and have routers to do PBR by DSCP marked. But I am still not sure if it will accurate enough.

In Windows you could use Policy Based QoS to set DSCP matching on the application name (applied through group policy)

edit: document refers to Server 2008 but the feature seems to available on Windows 7 Desktop as well
