系统内冗余或重复数据的度量,表明存储和潜在性能问题效率低下。
1 RR = 0.5 SR
1 SR = 2 RR
例子:
将15 冗余比率转换为信号冗余:
15 RR = 7.5 SR
| 冗余比率 | 信号冗余 |
|---|---|
| 0.01 RR | 0.005 SR |
| 0.1 RR | 0.05 SR |
| 1 RR | 0.5 SR |
| 2 RR | 1 SR |
| 3 RR | 1.5 SR |
| 5 RR | 2.5 SR |
| 10 RR | 5 SR |
| 20 RR | 10 SR |
| 30 RR | 15 SR |
| 40 RR | 20 SR |
| 50 RR | 25 SR |
| 60 RR | 30 SR |
| 70 RR | 35 SR |
| 80 RR | 40 SR |
| 90 RR | 45 SR |
| 100 RR | 50 SR |
| 250 RR | 125 SR |
| 500 RR | 250 SR |
| 750 RR | 375 SR |
| 1000 RR | 500 SR |
| 10000 RR | 5,000 SR |
