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.Client traffic classifiers support IPv4 addresses only.
Configuring client traffic shaping
Client rate shaping allows you to shape
client-side traffic from Windows client systems, based on traffic parameters.
Client traffic classifiers works on UPLOAD
TRAFFIC ONLY.
- 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.
Together, the client rate class and client
traffic classifier work to provide client-side traffic control to Windows clients to
which the traffic control is applied.
Select the client traffic classifier in the
Network Settings
configuration of a network access resource. The client traffic classifier is then
applied to Windows clients, for client-side traffic on the VPN tunnels defined by that
network access resource.Creating a client
rate class
Create a client rate class to define the traffic
shaping rules that you can apply to virtual and physical interfaces on a network access
tunnel.
- On the Main tab, click.
- ClickCreate.The New Client Rate Class screen opens.
- In theNamefield, type the name for the new client rate class.
- SelectBasicorAdvanced.The Advanced configuration allows you to configure the burst size, the rate class mode, and override the DSCP code.
- In theBase Ratefield, type the base rate for the client rate class. Select the units for the peak rate from the list (bps,Kbps,Mbps, orGbps).
- In theCeiling Ratefield, type the peak rate for the client rate class. Select the units for the ceiling rate from the list (bps,Kbps,Mbps, orGbps).
- In theBurst Sizefield, 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, orGigabytes).
- From theService Typelist, select the service type.
- From theModelist, 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 DSCPOverridecheck box.In the field, type the number of the DSCP code with which to mark traffic.
- ClickFinished.
The client rate class is created.
Select this client rate class in a client traffic
classifier to apply it to Windows client-side traffic.
Client rate class properties
Client rate class properties specify settings for client traffic control
rates.
Setting | Value | Description |
---|---|---|
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
You must create at least one client rate class before you create a client traffic classifier.
You select client rate classes to define rules in the client traffic classifier.
Create a client traffic classifier to define traffic control rules for the virtual and
physical network interfaces on a network access tunnel.
- On theMaintab, click .
- ClickCreate.The New client rate class screen opens.
- In theNamebox, type a name for the client traffic classifier, and clickCreate.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 typeDescriptionRules for Virtual Network Access InterfaceAdd a rule to this section to apply the traffic shaping control only to traffic on the virtual network access interface.Rules for Local Physical InterfacesAdd 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 InterfacesAdd 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
You add entries to an existing client traffic classifier. You must first create a
client traffic classifier, and at least one client rate class.
Client traffic classifiers define client traffic
control for virtual and physical network interfaces on the client systems.
- On the Main tab, click.
- Click the name of a client traffic classifier.
- Under the appropriate interfaceRulesarea, clickAdd.The New Client Traffic Classifier Entry screen opens.
- SelectBasicorAdvanced.Advancedmode allows you to configure a source address and source ports for the client traffic control entry.
- Select aClient Rate Classentry.
- 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, clickFinished.The configuration screen for the client traffic classifier appears again.
The client traffic classifier is updated with the client traffic classifier entry in
the
Rules
area you specified.
Client traffic classifier entry properties
Configure properties for the client traffic classifier to determine how traffic is classified
for traffic shaping on Windows clients.
Property | Values | Description |
---|---|---|
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. |
