Field Summary

static int	MIN_DOWNLOAD_BYTES_PER_SEC
static int	MIN_UPLOAD_BYTES_PER_SEC
static int	RATE_UNLIMITED
static int	START_DOWNLOAD_RATE_MAX
static int	START_UPLOAD_RATE_MAX

Method Summary

static int	calculateMinDownload(int maxBytesPerSec)
static int	calculateMinUpload(int maxBytesPerSec) Rule: Min value is alway 10% of max, but not below 5k.
static int	checkForMinDownloadValue(int rateBytesPerSec)
static int	checkForMinUploadValue(int rateBytesPerSec) No limit should go below 5k bytes/sec.
static SpeedManagerLimitEstimate	filterEstimate(SpeedManagerLimitEstimate estimate, int startValue) Early in the search process the ping-mapper can give estimates that are too low due to a lack of information.
static int	filterLimit(int bytesPerSec, int startValue)

Method Detail

checkForMinUploadValue

public static int checkForMinUploadValue(int rateBytesPerSec)

No limit should go below 5k bytes/sec.

Parameters:

rateBytesPerSec - -

Returns:

- "bytes/sec" rate.

checkForMinDownloadValue

public static int checkForMinDownloadValue(int rateBytesPerSec)

calculateMinUpload

public static int calculateMinUpload(int maxBytesPerSec)

Rule: Min value is alway 10% of max, but not below 5k.

Parameters:

maxBytesPerSec - -

Returns:

- minRate.

calculateMinDownload

public static int calculateMinDownload(int maxBytesPerSec)

filterEstimate

public static SpeedManagerLimitEstimate filterEstimate(SpeedManagerLimitEstimate estimate,
                                                       int startValue)

Early in the search process the ping-mapper can give estimates that are too low due to a lack of information. The starting upload and download limits is 60K/30K should not go below the starting value a slow DSL lines should.

Parameters:

estimate - - download rate estimate.

startValue - - starting upload/download value.

Returns:

-

filterLimit

public static int filterLimit(int bytesPerSec,
                              int startValue)
