A connectivity profile defines connectivity and client settings for a Network Access session.
A connectivity profile contains:
A connectivity profile is also associated with customizable client download packages for Edge Client for Windows and Edge Client for Mac.
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.
You can configure the following general settings in a connectivity profile.
|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.
Note: FEC profiles might not be available on all BIG-IP® systems.
|Description||Text.||Text description of the connectivity profile.|
You can configure the following network access compression settings in a connectivity profile.
|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.|
You can configure the following application tunnel compression settings in a connectivity profile.
|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.|
