存储转发是网络传输的一种形式，其问题是不确定在每个节点上的延迟时间。克服该问题最有效的方式是（ ）。
- A.设计更有效的网络缓冲区分配算法
- B.设置更大的缓冲区
- C.提高传输介质的传输能力
- D.减少分组的长度
正确答案及解析
正确答案
解析
本题考查的知识点为交换方式、拥塞控制方面的基本知识。
首先来看选项A，设计更有效的网络缓冲区分配算法对于解决延迟问题效果不明显。
然后看选项B，设置更大的缓冲区可能反而导致延迟时间的增加。
接着看选项C，提高传输介质的传输能力，会使得接收到分组后能迅速地从输出介质上传送出去，是减少延迟的最有效措施的方法。所以此题选C。
选项D的话，减少分组的长度是不能解决延迟问题的。
