| 13 | 9 | Greg Burri | |_.Name|_.Value |_.Unit|_.Explanation/Comments| |
| 14 | 14 | Greg Burri | | _ChunkSize_ | 33554432 | [Byte] | (32 MB) | |
| 15 | | _LanSpeed_ | 52428800 | [Byte/s] | (50 MB/s) | |
||
| 16 | 1 | Greg Burri | | _TimeRecheckChunkFactorv | 4 | - | If the time to download a chunk exceeds _TimeRecheckChunkFactor_ * ChunkSize / LanSpeed then the peers are rescanned to choose a better one (better download rate). For example : 4 * 32 / 50 = 2.6 second | |
| 17 | 13 | Greg Burri | | _SwitchToAnotherPeerFactor_ | 1.5 | - | During the recheck of the peers to choose a better one the other download rate must be above the current * _SwitchToAnotherPeerFactor_ | |
| 18 | 14 | Greg Burri | | _DownloadRateValidTime_ | 1500 / _LanSpeed_ = 300 s | [s] | (5 min). The download rate of a peer is valid this time after its last update. After that it's equals to the maximum. | |
| 19 | | _TimeBetweenChunksUpdate_ | 500 / _LanSpeed_ = 10 s | [s] | Each 10 s a daemon will scan the __ first chunks from the first queued downloads to know which peer has which chunk. | |
