Service Policy Configuration


IT service policies

You can use the WANJet appliance to define IT service policies and Application Quality of Service (QoS) policies for your various applications, and to 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:

  • Mission-critical applications
  • Video and voice streaming
  • Interactive video or voice
  • Data transfers
  • Web-based applications

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.

The IT Service Policy feature enables you to define services used 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 single type of traffic.

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

  1. In the navigation pane, expand Optimization and click IT Service Policy.
    The WANJet IT Service Policies screen displays.
  2. Click the Add button.
    The Add IT Service Policy screen displays in separate browser window.
  3. In the Policy Name box, type a name for the service.
  4. 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.
  5. In the Netmask box, type the full netmask (in dotted quad format) of the subnet that sends the data, for which you want to specify an IT service policy.
  6. In the To box, specify the subnet that receives the data, for which you want to specify an IT service policy.
  7. In the Netmask box, type the full netmask (in dotted quad format) of the subnet that receives the data, for which you want to specify an IT Service Policy.
  8. You can specify a port in one of the following ways:
    • From the Ports list, select a port.
    • In the From Port and To boxes, specify a range of ports.
  9. From the Protocol list, select a protocol type for the ports that you specified.
  10. 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.
  11. Click the Save button to save the changes.

To edit or remove an IT service policy

  1. In the navigation pane, expand Optimization and click IT Service Policy.
    The WANJet IT Service Policies screen displays.
  2. Click the name of the IT policy that you want to edit or remove.
    The Edit IT Service Policies screen displays in separate browser window.
  3. Edit the policy settings, or click the Remove button to delete the policy.
  4. The Edit IT Service Policies screen closes and the WANJet IT Service Policies screen refreshes with the new IT Service Policy displayed.
  5. Click the Save button to save the changes.

Application QoS Policy

The Application QoS Policy feature helps you obtain better network performance by dedicating bandwidth to specific network traffic. 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. The Application QoS Polices handle two types of services:

  • Fundamental services
    The basic protocols supported by your network.
  • IT service policies
    Tailored services that include different types of traffic.
    (See IT service policies .)

Adding, editing, or removing an Application QoS Policy

You can add, edit, or remove an Application QoS Policy from the Manage the Application QoS Settings of a Remote WanJet screen.

To add an Application QoS Policy to a remote WANJet appliance

  1. In the navigation pane, expand Optimization and click Application QoS.
    The Application QoS screen displays.
  2. From 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 screen displays in separate browser window.
  3. In the Link Bandwidth box, type the bandwidth size of the link between the local WANJet appliance and the remote WANJet appliance.
  4. From the Link Bandwidth list, select a unit (Kb/s or Mb/s).
  5. Click the OK button.
    The Application QoS Policy screen displays in a separate browser window.
  6. In the Alias box, type a name for the policy.
  7. In the Bandwidth box, type the minimum percentage of bandwidth that the policy should use.
  8. In the Maximum box, type the maximum percentage that the policy can use.The maximum amount of bandwidth is used only when there is plenty of link bandwidth available.
  9. From the Services menu, select the ports or IT service policies to use for the policy.
  10. From the adjacent service type list, select the associated protocol (TCP or UDP).
    • Note: You can configure a port for both TCP and UPD protocols. To do this, select the port, for example FTP, and select TCP. Then on a new line, select FTP again, and UDP. If you select VoIP, it uses only the UDP protocol. If you select an IT Service Policy from the menu, the adjacent service type menu disappears.
  11. Click the OK button.
    The Application QoS screen displays.
  12. Click the Save button.
    The Application QoS screen refreshes.

To edit or remove an Application QoS Policy from a remote WANJet appliance

  1. In the navigation pane, expand Optimization and click Application QoS.
    The Application QoS screen displays.
  2. 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 screen displays in separate browser window.
  3. Click the link for the Application QoS Policy that you want to edit or remove.
  4. Edit the settings or click the Remove button to delete the policy.
  5. Click the OK button.
    The Application QoS screen displays.
  6. Click the Save button.
    The Application QoS screen refreshes.

WAN Links

With the WAN Links feature, 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 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.
