Configuring Service Policies
Defining IT service policies
With the IT service policy feature, you define services that you can use to achieve specific QoS standards. You can group ports, machines, and subnets under the heading of an IT service policy. By assigning a minimum and a maximum amount of bandwidth to this service (in an Application QoS policy), you treat this group of ports, machines, and subnets as one entity. This is simpler than creating many different services, each of which handles a single type of traffic.
You can use the WANJet appliance to define IT service policies and Application Quality of Service (QoS) policies for your various applications, and apply them to optimally allocate bandwidth. An IT service policy specifies a named group of ports, machines, and subnets. When you define an Application QoS policy, you can specify an IT service group as well as the bandwidth you want to allocate to particular applications, such as:
These individual classes of applications have very different network requirements. The challenge is to align the network services to the application's requirements from a performance perspective.
Adding, editing, or removing an IT service policy
You can add, edit, or remove an IT service policy from the IT Service Policy screen.
To add an IT service policy
- In the navigation pane, expand Optimization and click IT Service Policy.
The WANJet IT Service Policies screen opens. - Click the Add button.
The Add IT Service Policy popup screen opens. - In the Policy Name box, type a name for the policy.
- In the From box, type the IP address of the subnet that sends the data, for which you want to specify an IT service policy.
- In the Netmask box, type the full netmask of the subnet that sends the data, for which you want to specify an IT service policy.
- In the To box, specify the subnet that receives the data, for which you want to specify an IT service policy.
- In the Netmask box, type the full netmask of the subnet that receives the data, for which you want to specify an IT service Policy.
- You can specify a port in one of the following ways:
- From the Protocol list, select a protocol type for the ports that you specified.
- Click the OK button.
The Add IT Service Policy screen closes, and the WANJet IT Service Policies screen refreshes with the new IT service policy displayed. - Click the Save button to save the changes.
To edit or remove an IT service policy
- In the navigation pane, expand Optimization and click IT Service Policy.
The WANJet IT Service Policies screen opens. - Click the name of the IT service policy that you want to edit or remove.
The Edit IT Service Policies screen displays in a separate browser window. - Edit the policy settings, or click the Remove button to delete the policy.
The Edit IT Service Policies screen closes and the WANJet IT Service Policies screen refreshes with the new IT Service Policy displayed. - Click the Save button to save the changes.
Creating Application QoS policies
Application QoS policies help you to obtain better network performance by dedicating bandwidth to specific network traffic traveling between two WANJet appliances. At the same time, you can ensure that providing sufficient bandwidth to one or more data flows does not handicap the transmission of other data flows. Application QoS is a per endpoint setting that you can use to override the tuning page bandwidth setting in a multi-node network.
The Application QoS polices handle two types of services:
- Fundamental services
The basic protocols supported by your network, such as FTP, HTTP, HTTPS, Pop3, and so on. - IT service policies
Tailored services that include different types of traffic. If you want to create an Application QoS policy to handle tailored services, you need to have created or imported the IT service policy already.
(See Defining IT service policies .)
Before you create an Application QoS policy, you need to plan how you want to allocate bandwidth.
Adding, editing, or removing an Application QoS policy
You can add, edit, or remove an Application QoS policy from the screen, Manage the Application QoS Settings of a Remote WanJet.
To add an Application QoS policy to a remote WANJet appliance
- In the navigation pane, expand Optimization and click Application QoS.
The Application QoS screen opens. - In the table, click the IP address of the remote WANJet appliance to which you want to apply an Application QoS policy.
The Manage the Application QoS Settings of a Remote WANJet appliance popup screen opens. - In the Link Bandwidth box, type the bandwidth size of the link between the local WANJet and the remote WANJet, and from the Link Bandwidth list, select a unit (Kb/s or Mb/s).
- Click the Add button.
The Application QoS Policy popup screen opens. - In the Alias box, type a name for the policy.
- In the Bandwidth box, type the percentage of bandwidth that you want to guarantee that the policy can use. For example, if you specify 50%, the connections associated with the policy are guaranteed 50% of the available bandwidth if needed.
- In the Maximum box, type the maximum percentage that the policy can borrow from unused additional bandwidth. For example, if you specify 90%, the connections associated with the policy can use up to 90% of the additional bandwidth that is available.
- In the Services box, add the services or IT service policies to use for the Application QoS policy. For each service that you add:
- Repeat steps 4-8 to add as many other Application QoS policies as you need.
- Click the OK button.
The Manage the Application QoS Settings of a Remote WANJet appliance popup screen closes. - Click the Save button.
The Application QoS screen refreshes.
To edit or remove an Application QoS policy from a remote WANJet appliance
- In the navigation pane, expand Optimization and click Application QoS.
The Application QoS screen opens. - Click the link for the remote WANJet appliance for which you want to edit or remove an Application QoS policy.
The Manage the Application QoS Settings of a Remote WANJet appliance popup screen opens. - Click the link for the Application QoS policy that you want to edit or remove.
- Edit the settings to alter an existing policy, or click the Remove button to delete the policy.
- Click the OK button.
The Application QoS screen opens. - Click the Save button.
The Application QoS screen refreshes.
Managing WAN links
Using WAN links, you can add an Application QoS Policy to the traffic passing through the local WANJet appliance and going to a remote network, whether or not the remote network has a WANJet appliance installed. In this way, you can manage and manipulate the bandwidth size for all the traffic transferred through the local WANJet appliance, regardless of the traffic's processing mode.
Adding, editing, or removing WAN links
To add a new WAN link
- In the navigation pane, expand Optimization and click Application QoS.
The Application QoS screen opens. - Click the Add WAN Link button.

- In the Link Bandwidth box, type the size of the bandwidth between the local WANJet appliance and the WAN network.
- From the Link Bandwidth list, select a unit (Kb/s or Mb/s).
- Click the OK button.
The Manage the Application QoS Settings of a WAN Link screen closes, and the Application QoS screen refreshes with the new WAN link displayed. - Click the Save button to save the changes.
