Of course, other - * procedures are possible, and may work better for particular environments. - * - * - * FILLING THE RATE TABLE - * - * Given a particular initial rate and mode, as determined by the rate - * scaling algorithm described below, the Linux driver uses the following - * formula to fill the rs_table[LINK_QUAL_MAX_RETRY_NUM] rate table in the - * Link Quality command: - * - * - * 1) If using High-throughput (HT) (SISO or MIMO) initial rate: - * a) Use this same initial rate for first 3 entries. - * b) Find next lower available rate using same mode (SISO or MIMO), - * use for next 3 entries. If no lower rate available, switch to - * legacy mode (no HT40 channel, no MIMO, no short guard interval). - * c) If using MIMO, set command's mimo_delimiter to number of entries - * using MIMO (3 or 6). - * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, - * no MIMO, no short guard interval), at the next lower bit rate - * (e.g. if second HT bit rate was 54, try 48 legacy), and follow - * legacy procedure for remaining table entries. - * - * 2) If using legacy initial rate: - * a) Use the initial rate for only one entry. - * b) For each following entry, reduce the rate to next lower available - * rate, until reaching the lowest available rate. - * c) When reducing rate, also switch antenna selection. - * d) Once lowest available rate is reached, repeat this rate until - * rate table is filled (16 entries), switching antenna each entry. - * - * - * ACCUMULATING HISTORY - * - * The rate scaling algorithm for agn devices, as implemented in Linux driver, - * uses two sets of frame Tx success history: One for the current/active - * modulation mode, and one for a speculative/search mode that is being - * attempted. If the speculative mode turns out to be more effective (i.e. - * actual transfer rate is better), then the driver continues to use the - * speculative mode as the new current active mode. - * - * Each history set contains, separately for each possible rate, data for a - * sliding window of the 62 most recent tx attempts at that rate. The data - * includes a shifting bitmap of success(1)/failure(0), and sums of successful - * and attempted frames, from which the driver can additionally calculate a - * success ratio (success / attempted) and number of failures - * (attempted - success), and control the size of the window (attempted). - * The driver uses the bit map to remove successes from the success sum, as - * the oldest tx attempts fall out of the window. - * - * When the agn device makes multiple tx attempts for a given frame, each - * attempt might be at a different rate, and have different modulation - * characteristics (e.g. antenna, fat channel, short guard interval), as set - * up in the rate scaling table in the Link Quality command. The driver must - * determine which rate table entry was used for each tx attempt, to determine - * which rate-specific history to update, and record only those attempts that - * match the modulation characteristics of the history set. - * - * When using block-ack (aggregation), all frames are transmitted at the same - * rate, since there is no per-attempt acknowledgment from the destination - * station. The Tx response struct iwl_tx_resp indicates the Tx rate in - * rate_n_flags field. After receiving a block-ack, the driver can update - * history for the entire block all at once. - * - * - * FINDING BEST STARTING RATE: - * - * When working with a selected initial modulation mode (see below), the - * driver attempts to find a best initial rate. The initial rate is the - * first entry in the Link Quality command's rate table. - * - * 1) Calculate actual throughput (success ratio * expected throughput, see - * table below) for current initial rate. Do this only if enough frames - * have been attempted to make the value meaningful: at least 6 failed - * tx attempts, or at least 8 successes. If not enough, don't try rate - * scaling yet. - * - * 2) Find available rates adjacent to current initial rate. Available means: - * a) supported by hardware && - * b) supported by association && - * c) within any constraints selected by user - * - * 3) Gather measured throughputs for adjacent rates. These might not have - * enough history to calculate a throughput. That's okay, we might try - * using one of them anyway! - * - * 4) Try decreasing rate if, for current rate: - * a) success ratio is < 15% || - * b) lower adjacent rate has better measured throughput || - * c) higher adjacent rate has worse throughput, and lower is unmeasured - * - * As a sanity check, if decrease was determined above, leave rate - * unchanged if: - * a) lower rate unavailable - * b) success ratio at current rate > 85% (very good) - * c) current measured throughput is better than expected throughput - * of lower rate (under perfect 100% tx conditions, see table below) - * - * 5) Try increasing rate if, for current rate: - * a) success ratio is < 15% || - * b) both adjacent rates' throughputs are unmeasured (try it!) || - * b) higher adjacent rate has better measured throughput || - * c) lower adjacent rate has worse throughput, and higher is unmeasured - * - * As a sanity check, if increase was determined above, leave rate - * unchanged if: - * a) success ratio at current rate < 70%. This is not particularly - * good performance; higher rate is sure to have poorer success. - * - * 6) Re-evaluate the rate after each tx frame. If working with block- - * acknowledge, history and statistics may be calculated for the entire - * block (including prior history that fits within the history windows), - * before re-evaluation. - * - * FINDING BEST STARTING MODULATION MODE: - * - * After working with a modulation mode for a "while" (and doing rate scaling), - * the driver searches for a new initial mode in an attempt to improve - * throughput. The "while" is measured by numbers of attempted frames: - * - * For legacy mode, search for new mode after: - * 480 successful frames, or 160 failed frames - * For high-throughput modes (SISO or MIMO), search for new mode after: - * 4500 successful frames, or 400 failed frames - * - * Mode switch possibilities are (3 for each mode): - * - * For legacy: - * Change antenna, try SISO (if HT association), try MIMO (if HT association) - * For SISO: - * Change antenna, try MIMO, try shortened guard interval (SGI) - * For MIMO: - * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) - * - * When trying a new mode, use the same bit rate as the old/current mode when - * trying antenna switches and shortened guard interval. When switching to - * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate - * for which the expected throughput (under perfect conditions) is about the - * same or slightly better than the actual measured throughput delivered by - * the old/current mode. - * - * Actual throughput can be estimated by multiplying the expected throughput - * by the success ratio (successful / attempted tx frames). Frame size is - * not considered in this calculation; it assumes that frame size will average - * out to be fairly consistent over several samples. The following are - * metric values for expected throughput assuming 100% success ratio. - * Only G band has support for CCK rates: - * - * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 - * - * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 - * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 - * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 - * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 - * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 - * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 - * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 - * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 - * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 - * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 - * - * After the new mode has been tried for a short while (minimum of 6 failed - * frames or 8 successful frames), compare success ratio and actual throughput - * estimate of the new mode with the old.
