※ 引述《tedmax100 (tedmax)》之銘言:
: A secret agency simultaneously monitors 150 cellular phone conversations and
: multiplexes the data onto a network with a bandwidth of 5 MB/sec and an
: overhead latency of 150 μs per 1 KB message.
: Calculate the transmission time per message and determine whether there is
: sufficient bandwidth to support this application.
: Assume that the phone conversation data consists of 2 bytes sampled
: at a rate of 4 KHz.
: 想問問這題 這問題是有兩個答案嗎? 計算每個訊息的傳遞時間 跟 定義頻寬嗎?
: 請問怎解@@"
: 第一個時間 是 4KHz*2byets*150 conversations = 1200Kbytes ?
: 接著要怎下去
----------------------------------------------------------------------------
接著算出
Trasmission time per 1KB
=transmission time + overhead latency time
最後算出
Total time required to monitor (sec)!!
