Dscp marking windows 2008 r2

Trending Now. Home » Networking. First Log in to Windows 7 as an administrator. Right click Policy-based QoS and select Create new policy from the menu. Figure 1 Now you can apply the policy to an application or server URL.

Select Only applications with this executable name , type the name of the application to which you want the policy to apply and click Next. For simplicity, leave the default selections for any source and destination IP addresses and click Next. Figure 3 Now restart Windows 7.

ID values range from 0 to 7. When DSCP configuration registry keys are missing in the miniport registry, the following defaults are assigned:. To verify that all QoS and DSCP settings were correct, you can capture incoming and outgoing traffic by using the ibdump tool and see the DSCP value in the captured packets as displayed in the figure below. Quick Search. Hit enter to search. WinOF v5. For example, the following paths are listed by priority:.

If a user chooses to include all subdirectories and files following a URL path, this URL path will have a lower priority than it would have if the choice were not made.

The destination IP address has a lower priority than any of the four URL fields described previously. A Quintuple policy always has a higher precedence than any URL-based policy.

Based on the previous line-of-business application example, you can see that QoS for networks is an industry-wide set of standards and mechanisms for ensuring high-quality performance for mission-critical applications. By using QoS mechanisms, network administrators can use existing resources efficiently and ensure the required level of service without reactively expanding or over-provisioning their networks. Configuration of this combination makes for easy application of QoS policies to Group Policy Objects.

Windows includes a Policy-based QoS Wizard to help you:. Before you create a QoS policy, it is important that you understand the two key QoS controls that are used to manage network traffic:. Network routers use the DSCP value to classify network packets and to queue them appropriately. The number of queues and their prioritization behavior needs to be designed as part of your organization's QoS strategy.

For example, your organization may choose to have five queues: latency-sensitive traffic, control traffic, business-critical traffic, best-effort traffic, and bulk-data-transfer traffic. Along with DSCP values, throttling is another key control for managing network bandwidth. As mentioned earlier, you can use the Specify Throttle Rate setting to configure a QoS policy with a specific throttle rate for outbound traffic. By using throttling, a QoS policy limits the outgoing network traffic to a specified throttle rate.

Both DSCP marking and throttling can be used together to manage traffic effectively. QoS policy names must be unique. How policies are applied to servers and end users depends on where the QoS policy is stored in the Group Policy Object Editor:.

You typically use computer-based QoS policies for server computers. On the first page of the Policy-based QoS wizard, you can specify a policy name and configure how QoS controls outgoing network traffic. In Policy name , type a name for the QoS policy. The name must uniquely identify the policy. Optionally, use Specify Throttle Rate to enable traffic throttling and configure the throttle rate.

The throttle rate value must be greater than 1 and you can specify units of kilobytes per second KBps or megabytes per second MBps. In the second page of the Policy-based QoS wizard you can apply the policy to all applications, to a specific application as identified by its executable name, to a path and application name, or to the HTTP server applications that handle requests for a specific URL. All applications specifies that the traffic management settings on the first page of the Policy-based QoS wizard apply to all applications.

Only applications with this executable name specifies that the traffic management settings on the first page of the Policy-based QoS wizard are for a specific application. The executable file name and must end with the. Optionally, you can enter the application path. To specify an application path, include the path with the application name.

The path can include environment variables. Optionally, you can check Include subdirectories and files to perform matching on all subdirectories and files following a URL. In This QoS policy applies to , select either All applications or Only applications with this executable name. If you select Only applications with this executable name , specify an executable name ending with the.

If you select Only for the following source IP address or Only for the following destination IP address , you must type one of the following:. On the other hand, you can still customize the policy by specifying the destination IP address. This makes it possible for you to create different policies for different clients by using the same HTTP server applications. If you selected Only for the following IP destination address , specify an IPv4 or IPv6 address or prefix that corresponds to the type of address or prefix specified for the source address.

On the fourth page of the Policy-based QoS wizard, you can specify the types of traffic and the ports that are controlled by the settings on the first page of the wizard. You can specify:. In Specify the source port number , select From any source port or From this source port number. If you selected From this source port number , type a port number between 1 and Optionally, you can specify a port range, in the format of " Low : High ," where Low and High represent the lower bounds and upper bounds of the port range, inclusively.

Low and High each must be a number between 1 and No space is allowed between the colon : character and the numbers. In Specify the destination port number , select To any destination port or To this destination port number.

If you selected To this destination port number in the previous step, type a port number between 1 and Thanks for posting here. So the resolution is that we can set the Qos via group policy like what Ace mentioned:. Change the application to use qwave.
