Question

请教一道计算机题目：

6. Suppose an application generates chunks of 40 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will be overhead and what percentage will be application data?

Answer 1

25% for TCP overhead, 25% for IP overhead and 50% for application data. Because each chunk contains 20 bytes IP header and 20 bytes TCP header with 40 bytes of date.

Answer 2

假定一种应用产生数据的40字节的厚片每msec 20,在一个TCP部分然后一IP datagram中把每一厚片封入内部,每一datagram的百分比将是头顶上的和百分比将是应用数据的?
