Defining Connectivity Options
About connectivity
profiles and Network Access
A connectivity profile defines connectivity and client settings for a
Network Access session.
A connectivity profile contains:
- Compression settings for network access connections and application tunnels
- Citrix client settings
- Virtual servers and DNS-location awareness settings for BIG-IP Edge Client® for Windows, Mac, and Linux
- Password caching settings for BIG-IP Edge Client for Windows, Mac, and mobile clients
- Settings for mobile clients
A connectivity profile is also associated with customizable client
download packages for Edge Client for Windows and Edge Client for Mac.
Create a connectivity profile foraccess tunnels and
clients
You create a connectivity profile to
configure client connections for a network access tunnel, application access tunnel, and
clients.
- On the Main tab, click .A list of connectivity profiles displays.
- ClickAdd.The Create New Connectivity Profile popup screen opens and displays General Settings.
- Type aProfile Namefor the connectivity profile.
- Select aParent Profilefrom the list.APM provides a default profile,connectivity.
- From the Compression Settings folder, clickNetwork Accessand make changes to the network access compression settings.The settings specify available compression codecs for server-to-client connections.The default settings are displayed in the right pane.
- From the Compression Settings folder, clickApp Tunneland make changes to the application tunnel compression settings.The settings specify available compression codecs for server-to-client connections. By default, compression is enabled, but no codecs are selected in the Available Codecs area.The default settings are displayed in the right pane.
- ClickOK.The popup screen closes, and the Connectivity Profile List displays.
To provide functionality with a connectivity profile, you
must add the connectivity profile and an access profile to a virtual server.
About connectivity
profile compression settings
Compression settings specify the available compression codecs for
server-to-client connections. The server compares the available compression types configured in
the connectivity profile with the available compression types on the client, and chooses the most
effective mutual compression setting.
Connectivity profile general settings
You can configure the following general settings in a connectivity profile.
Profile setting |
Value |
Description |
|---|---|---|
Profile Name |
Text. |
Text specifying name of the connectivity profile. |
Parent Profile |
A connectivity profile, selected from a list. |
A profile inherits settings from its parent profile. |
FEC Profile |
A forward error correcting (FEC) profile, selected from a list. |
A FEC profile applies to a network access tunnel.
FEC profiles might not be available on all BIG-IP systems. |
Description |
Text. |
Text description of the connectivity profile. |
Connectivity profile network access compression settings
You can configure the following network access compression settings in a connectivity
profile.
Setting |
Value |
Description |
|---|---|---|
Compression Buffer Size |
Number of bytes. The default is 4096 . |
Specifies the size of the output buffers containing compressed data. |
gzip Compression Level |
A preset, or a value between 1 and
9 . |
Specifies the degree to which the system compresses the content. Higher compression
levels cause the compression process to be slower and the result to be more compressed. The
default compression level is 6 - Optimal Compression (Recommended) ,
which provides a balance between level of compression and CPU processing time. You can also
select compression level 1 - Least Compression (Fastest) , the lowest
amount of compression, which requires the least processing time, or 9 - Most
Compression (Slowest) , the highest level of compression, which requires the most
processing time. You can also select a number between 1 and
9 . |
gzip Memory Level |
1 -256 kb. |
Specifies the number of kilobytes of memory that the system uses for internal
compression buffers when compressing data. You can select a value between
1 and 256 . |
gzip Window Size |
1 -128 kb. |
Specifies the number of kilobytes in the window size that the system uses when
compressing data. You can select a value between 1 and
128 . |
CPU Saver |
Selected or cleared. |
Specifies, when enabled, that the system monitors the percentage of CPU usage and
adjusts compression rates automatically when the CPU usage reaches either the
High value or the Low Value. |
High |
Percentage |
Specifies the percentage of CPU usage at which the system starts automatically
decreasing the amount of content being compressed, as well as the amount of compression which
the system is applying. |
Low |
Percentage |
Specifies the percentage of CPU usage at which the system resumes content compression
at the user-defined rates. |
Connectivity profile application tunnel compression settings
You can configure the following application tunnel compression settings in a connectivity
profile.
Setting |
Value |
Description |
|---|---|---|
Compression |
Enable or Disable |
Specifies the available compression codecs for server-to-client connections. The
server compares the available compression types configured here, with the available compression
types on the client, and chooses the most effective mutual compression setting. |
Adaptive Compression |
Enable or Disable |
Specifies whether to enable to disable adaptive compression between the client and the
server. |
Deflate Level |
From 1 to 9 |
Specifies a compression level for deflate compression. Higher numbers compress more,
at the cost of more processing time. |
lzo |
Enable or Disable |
Specifies LZO compression. LZO compression offers a balance between CPU resources and
compression ratio, compressing more than Deflate compression, but with less CPU resources than
Bzip2. |
deflate |
Enable or Disable |
Specifies deflate compression. Deflate compression uses the least CPU resources, but
compresses the least effectively. |
bzip2 |
Enable or Disable |
Specifies Bzip2 compression. Bzip2 compression uses the most CPU resources, but
compresses the most effectively. |
