大家好,這是我最近這2天碰到的一個題目。
Consider a short, 15- meter link. Over which a sender can transmit at a rate of 160bps in both directions. Suppose that packet containing data are 200kbits long, and packets containing only control are 100 bits long. Assume that N parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 200kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. Would parallel downloads via parallel instances of non-persistent HTTP make sense in the case? Now consider persistent HTPP. Do you expect significant gains over the non-persistent case? Justify and explain your answer.
題目方面我看的不是很明白,麻煩請各位大哥大姊替我解答一下,希望可以簡單敘述一下題目內容,並且幫忙解題一下 !! 感謝大家。
