Class of Service vs. Quality of Service

Hello group,

We are in the beginning of a major network upgrade. We currently run network services on a NetVPN (ATT) network and are migrating to AVPN. As we move forward, we're going to be building in Class of Service based on available configurations. We currently use QoS to mange traffic on our routers. (I'm a bit new with some of this stuff, so pardon me if I mangle terms.) I am doing some research, but when you don't know, what you don't know..... So, I'm wondering if we'll need to 'blow away' our current configuration to accomodate the new CoS? Here's a code snippet of our current configuration:

Class map and policy map:

!

class-map match-any Business_Ingress

match access-group 130

class-map match-any Business_Data

match ip dscp af21

match access-group 130

class-map match-any ATM_Traffic

match access-group 140

class-map match-any Voice

match  dscp ef

match access-group name Voice-Traffic

class-map match-any Replication

match access-group 150

class-map match-any Voice_Ingress

match access-group name Voice-Traffic

!

!

policy-map Voice-Traffic

class Voice

  priority percent 15

class Business_Data

  bandwidth percent 64

class Replication

    police 7000000

class ATM_Traffic

  priority percent 5

class class-default

policy-map WAN_QOS

class class-default

  shape average 10000000

  service-policy Voice-Traffic

policy-map QOS_INGRESS_LAN

class Business_Ingress

  set ip dscp af21

class Voice_Ingress

  set ip dscp ef

If you are talking about outbound QOS pointed toward the wan, the first thing you need to do is understand what the wan provider will accept. You can come up with a very finely detailed 13 cos breakdown of all your traffic, but if the wan provider is only going to accept 5 classes, it doesn't really matter. Find out what Avpn will accept and tune your markings to those.

The next thing I would personally recommend is to keep it simple. Start with voice, then add mission critical business, then maybe video, then everything else. Start with a simple policy, mark the outbound to what the provider will accept, set priority queue for voice, insure your mission critical has a large enough reservation and you'll likely have 90% of your problem solved.
