你的Internet连接速度究竟有多快呢?不同类型的连接总是承诺不同的连接速率,但是这些承诺是否真实地反映了我们的实际情况呢?网络拥堵经常会使实际速率低于标称的数值。电缆调制解调器有时能够取得较高的传输速率,但是这取决于仅有有限的几个邻居在共享这条线路。如果我们改成DSL会怎样呢?
How fast is your Internet connection? Different types of connections always promise different connection rates, but do these commitments truly reflect our realities? Network congestion often causes actual rates to fall below a nominal value . Cable modems can sometimes achieve higher transfer rates, but this depends on having only a limited number of neighbors sharing the line. What if we change to DSL?
