1、A transport layer protocol usually has several responsibilities ． One is to create a process-to-process communication;UDP uses (71)numbers to accomplish this ． Another Responsibility is to provide control mechanisms at the  transpt level．UDP does this task at a very minimal level ． There is no flow control mechanism and there Is no(72) for received packet． UDP,however ,does provide error control to some extent．If UDP detects an error in the received packet,it will silently drop it．The transport layer also provides a connection mechanism for the processes．The(73)must be able to send streams of data to the transport layer．It is the responsibility of the transport layer at (74)station to make the connection with the receiver．chop the stream into transportable units,number them,and send them one by one．It is theresponsibility of th transorort layer at the receiving end to wait until all the different units  belong to th same process have arrived,check and pass those that are(75) free ,and deliver them to the receiving process as a stream．
