polling rate 中文意思是什麼
-
3 standard adopted in ethernet designates 368 bits minimum data field size in mac fraae, filling bits will be loaded if data length is shorter than 368 bits, which causes extra spending. on the contrary, the naxiaub process data length in iec 61375 - 1 is only 256 bits. ( 2 ) actual ethernet rate may be lombps, loombps, looombps, which is far higher than 1vl consequently it is likely that csma / cd fulfill functions of mvb polling strategy
3標準指定的mac幀最短數據域長是368位，不夠時應裝入填充比特，造成不必要的開銷，而iec61375 - 1規定的最短過程數據僅為16位，最長不過256位； （ 2 ）由於歸一化速率為1mbps ，而實際的ethernet傳輸速率遠遠高於1mbps 。
