Each machine supporting TCP has a TCP transport entity, either a library procedure, a user process, or part of the kernel. In all case, it manages TCP streams and () to the IP layer.A TCP () accepts user data streams from local process, breaks them into pieces not exceeding 64KB, and sends each piece as a separate IP () . When datagrams containing TCP data arrive at a machine, they are given to the TCP entity, which reconstructs the original byte streams.The IP layer gives no guarantee that datagrams will be delivered properly, so it is up to TCP to time out and () them as need be. Datagrams do arrive may well do so in the wrong order,it is also up to TCP to () them into messages in the proper sequence.A.connectionB.fileC.entityD.destination
选项
A.connection
B.file
C.entity
D.destination
答案
C
解析
么是部分内核。任何情况下,他都负责管理TCP流和IP层的接口。一个TCP实体从当前进程接收用户数据流,并将这些数据分割为不超过64KB的数据块,并将每个数据块当成一个个分割的数据报。当包含TCP数据的数据报到达一台主机时,他们被看成TCP实体,这些实体会按原来字节流进行重建。在IP层不能保证数据报的传输是正确的,因此等传输超过TCP时间后,就会要求重传。这些数据报到达的次序可能不是原先的那样,这就需要TCP实体将这些数据报重新排序还原为原先的、正确的信息。
