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. The use of containers gives a very helpful method of transport.

• B、 A single join interface can be defined and associated with a given OTV overlay.
• C、 Multiple overlays can also share the same join interface.
• D、 Join interface can be a loopback interface.
• E、 The join interface is a Layer 3 entity that can be defined as a physical interface but not as a logical one.
