nternational Transport Transport plays an important part in international business because goods produced have to be delivered to the buyers abroad, and the delivery of goods is to be made possible by transport services. Goods are carried by several means of transport on road or rail, by sea or air. And in recent years, combined transport which is a road-sea-rail carriage appeared. With the expansion of international trade, the container service has become popular. The use of containers provides a , highly effective form of transport . by road, rail and sea, Basically , orabout 98% of world trade is carried out by sea transport.Besides transport by sea, road, or rail, nowadays in order to speed up delivery, carriage by air international has also become popular. Transport plays an important part in international business because goods produced have to be sent to everywhere in the world.

In optical channel transport unit overhead (OTU OH), what are general communication channels 1 and 2(GCC1/GCC2) used for?()
A transport layer protocol has several responsibilities, One is to create a process-to-process (program-to-program) communication; TCP uses port (1) to accomplish this. Another responsibility of a transport layer protocol is to create a (2) and error-control mechanism at the transport level. TCP uses a sliding (3) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (4) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (5) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver. 空白(3)处应选择()

When the system upon which a transport entity is running fails and subsequently restarts,the(21) information of all active connections is lost. The affected connections become half-open, as the side that did not fail does not yet realize the problem.The still active side of a half-open connections can close the connection using a(22)timer. This timer measures the time the transport machine will continue to await an (23) of a transmitted segment after the segment has been retransmitted the maximum number of times.When the timer (24),the transport entity assumes that either the other transport entity or the intervening network has failed. As a result, the timer closes the connection, and signals an abnormal close to the TS user. In the event that a transport entity fails and quickly restarts, half-open connections can be terminated more quickly by the use of the RST segment, the failed side returns an RST i to every segment i that it receives. When the RST i reaches the other side, it must be checked for validity based on the (25) number i, as the RST could be in response to an old segment. If the reset is valid, the transport entity performs an abnormal termination. 空白处(23)应选择()
