Advanced QoS configuration

[Oneal1975]

Here is the basic network info:

6 remote sites with thin clients, VoIP phones, and some PC's

1 Central office

Database hosted in cloud environment

Thin clients at remote offices need to connect to central office via citrix

PC's at remote offices connect to the shares at Central office

PC's at remote offices connect to the hosted database

Central office connects to the hosted database

Thin clients connected to the central office citrix then route to the hosted database

Need to accomplish the following

Improve VoIP quality between sites

Gaurantee bandwidth and priority to hosted database connectionsduring times of WAN saturation for all locations

Gaurantee citrix connection to central office stays up and as fast as possible

Each remote location has 2 WAN connections, a 6 Mb and 2 Mb connection. 

The Central Location has a 50Mbps and 10Mbps connection

They are also using a PET topology between the offices.

Please let me know if you need any further information.

Thank you in advance for your help.

You need to further, and in detail, describe your logical and physical topologies.

QoS can be used to manage bandwidth, which should meet most or all of your service requirements, but for it to really work, it needs to manage all the bandwidth.

For example, if your WAN supports any kind of multipoint, i.e. where more than one other site has a path to another site, you can congest on egress to the destination site, but do you control that congestion point?

You can do a QoS as this :

class-map match-any TrafficoVoipCTRL
 match protocol skinny
 match access-group name TrafficoVoiceCtrl
 match access-group name TrafficoICM
 match protocol sip
class-map match-any TrafficoSQL
 match protocol sqlserver
 match protocol sqlnet
policy-map QosCentralToRemote

 class TrafficoSQL
  set ip dscp af21
  bandwidth percent 5
  random-detect

 class TrafficoVoipCTRL
  set ip dscp af31
  priority percent 20
