| 8. | 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标准指定的mac帧最短数据域长是368位，不够时应装入填充比特，造成不必要的开销，而iec61375 - 1规定的最短过程数据仅为16位，最长不过256位； ( 2 )由于归一化速率为1mbps ，而实际的ethernet传输速率远远高于1mbps 。 |
