Shaping Traffic on the Network Access Client
About Windows client traffic shaping
Used together, client traffic classifiers and client rate classes provide client-side traffic shaping features on Windows® network access client connections. You configure a client traffic classifier, which defines source and destination IP addresses or networks, and can also specify a protocol. The client traffic classifier is then associated with a client rate class, which defines base and peak rates for traffic to which it applies, and other traffic shaping features. A client traffic classifier is assigned in a network access resource.
Configuring client traffic shaping
- Create a client rate class.
- Create a client traffic classifier.When you create the client traffic classifier, you select the previously created client rate class.
Creating a client rate class
- On the Main tab, click .
- Click Create.The New Client Rate Class screen opens.
- In the Name field, type the name for the new client rate class.
- Select Basic or Advanced.The Advanced configuration allows you to configure the burst size, the rate class mode, and override the DSCP code.
- In the Base Rate field, type the base rate for the client rate class. Select the units for the peak rate from the list (bps, Kbps, Mbps, or Gbps).
- In the Ceiling Rate field, type the peak rate for the client rate class. Select the units for the ceiling rate from the list (bps, Kbps, Mbps, or Gbps).
- In the Burst Size field, type the amount of traffic that is allowed to reach the ceiling rate defined for the traffic rate class. You can select the units for this number from the list (bytes, Kilobytes, Megabytes, or Gigabytes).
- From the Service Type list, select the service type.
- From the Mode list, select the traffic shaping mode.
- (Optional) If you are using a differential services network, you can specify the DSCP value with which to mark this traffic by selecting the DSCP Override check box.In the field, type the number of the DSCP code with which to mark traffic.
- Click Finished.
Client rate class properties
Client rate class properties specify settings for client traffic control rates.
|Base Rate||Integer in bps, Kbps, Mbps, or Gbps||Specifies the base data rate defined for the client rate class.|
|Ceiling Rate||Integer in bps, Kbps, Mbps, or Gbps||Specifies the ceiling data rate defined for the client rate class.|
|Burst Size||Integer in bytes, Kilobytes, Megabytes, or Gigabytes||Specifies the amount of traffic that is allowed to reach the ceiling data rate defined for the client rate class.|
|Service Type||Best Effort, Controlled Load, or Guaranteed||
|Mode||Shape, Discard, or Borrow||
|DSCP||Enable/disable, integer for DSCP code||If you select Override, you can specify an optional DSCP code for the client rate class. DSCP is a way of classifying traffic for Quality of Service (QoS). Traffic is classified using six-bit values, and then routers on the network interpret the traffic priority based on their configurations and prioritize traffic for QoS accordingly.|
Creating a client traffic classifier
- On the Main tab, click .
- Click Create.The New client rate class screen opens.
- In the Name box, type a name for the client traffic classifier, and click Create.The Client Traffic Classifiers list screen opens.
- Click the name of the client traffic classifier you just created.
- Add rules for the appropriate interface.
Rule type Description Rules for Virtual Network Access Interface Add a rule to this section to apply the traffic shaping control only to traffic on the virtual network access interface. Rules for Local Physical Interfaces Add a rule to this section to apply the traffic shaping control only to traffic on the client computer's local physical interfaces. Rules for Virtual Network Access and Local Physical Interfaces Add a rule to this section to apply the traffic shaping control to traffic on both the virtual Network Access interface and the client's local physical interfaces.
Adding a client traffic classifier entry
- On the Main tab, click .
- Click the name of a client traffic classifier.
- Under the appropriate interface Rules area, click Add.The New Client Traffic Classifier Entry screen opens.
- Select Basic or Advanced.Advanced mode allows you to configure a source address and source ports for the client traffic control entry.
- Select a Client Rate Class entry.
- Specify any settings you require for the client traffic classifier entry.Note that currently you can only specify an IPv4 address for a client traffic classifier host entry.
- When you have finished configuring the client traffic classifier entry, click Finished.The configuration screen for the client traffic classifier appears again.
Client traffic classifier entry properties
Configure properties for the client traffic classifier to determine how traffic is classified for traffic shaping on Windows® clients.
|Basic/Advanced||Basic or Advanced (list item)||Advanced allows you to configure a source address and source ports.|
|Client Rate Class||List item||A client rate class defines the client traffic shaping rates and properties for a client traffic control configuration. Because client traffic classifier entries define address pairs and protocols on which client rate classes operate, a client rate class must be created before you can use a client traffic classifier entry.|
|Protocol||UDP, TCP, or All Protocols.||The protocol to which this client traffic classifier entry applies.|
|Destination Address||Selection and manual entries||The destination address to which the client traffic classifier entry applies.
|Destination Port||Number or list item||The destination port to which the client traffic classifier entry applies. You can type the port number, or select from the list of predefined application ports.|
|Source Address||Selection and manual entries||The source address to which the client traffic classifier entry applies.
|Source Port||Number or list item||The source port to which the client traffic classifier entry applies. You can type the port number, or select from the list of predefined application ports.|
