阅读下面的短文，回答问题 [When an IP packet arrives at a router, generally the router loo

ks at the destination address of the packet, and forwards the packet to one of its network interfaces. The forwarding decision is usually done by looking up the destination address from another data structure called a forwarding table. The forwarding table is created by the router using the routing table and possible routing policies existing in the router. The router then creates a table where it lists which networks are accessible through which of the router’s network interfaces. An IP router looks at every IP packet individually and does the forwarding decision on a packet-by-packet basis. If something changes in the router’s routing table, a packet can take a different route from a preceding packet even if it has the same destination.] From the paragraph above，we can see that the router （） a forwarding table according to the routing table and possible routing policies existing in the router. When an IP packet arrives at a router, the （） part of packet is normally checked by the router. An IP router checks every IP Packet individually and makes the forwarding decision based on （）.

A．is generating B．generate C．is generated D．generates A．forwarding table B．network interfaces C．routing policies D．destination address A．the destination address and network interfaces B．forwarding table and network interfaces C．the destination address and forward table D．routing policies and routing table

Essay 2 Transportation Decision Transportation decision consists of the following parts:

Essay 2 Transportation Decision

Transportation decision consists of the following parts:

1.Selection of the mode is determined by the consideration of distance,cargo weights,linkage,timing and other requirements.Generally speaking,rail has high fixed cost and the relatively low variable cost.It can move heavy,large quantity of cargo in the long distance.But,rail is disadvantaged because of the longer transit time and less frequent service than motor.

Motor carriers such as truck companies offer door-to-door service,that is,the cargo can be shipped from the shipper’s warehouse to theconsignee’s.Trucking fixed cost is the lowest of any carrier,because the equipment is fairly cheap and themotor carriers do not have to invest in the roads on which they run their operations.However,their variable costs are very high.Its expenses include two major components:firstly,the pick-up and delivery costs;secondly,there are gas or fuel costs,labor expenses and toll roads fees to be paid to highway and toll road operators.Therefore,motor transport is good for cargo with small quantity to be shipped within shortvdistances.

Water is the predominant choice of transportation as it has the capacity to take greatest quantity,travel longest distance with lowest cost.Transport by sea accounts for 80% of international trade.The major expenses for water are expenses associated with investment and maintenance of the ships and terminals.For example, a 100000- ton container ship costs US$ 200 million.Terminal associated costs include harbor fees and the cost for loading and unloading the goods.

Transport by air has the highest cost but it is fast with the lowest ratio of loss and damage. If you need to deliver an urgent order,there is little choice but by air.

2.Transport service provider is selected for its experiences,equipment,services and prices.Competitive in the transport industry usually drives the prices down and motivates for better services A company also chooses its transport service provider because of its long-standing business relationship with certain shipping companies.

3.The alternative routing and scheduling is specific for motor only because railway and water have strict route and timetable.

Motor has special advantage in terms of flexibility.It has the ability to load goods at greater frequency,travel through different routes and making deliveries to different locations.

Questions:

56.How is the transportation mode selected？ ()

A.By suppliers.

B.By customers.

C.By consideration of distance,weight,linkage and other requirements.

D.By government requirements.

第11题

4G is one of those terms that keep coming back through marketing brochures for what the la

test technologies happen to be in the cellphone market. Every carrier claims to have true 4G, and has been claiming that for years, regardless of what they actually use. The reason was simple because the real 4G specification, expected to be drafted by the International Telecommunication Union, was no where to be found. In fact, the ITU took way longer than being expected to come up with a decision, likely because of massive lobbying campaigns. After all, which company wants to have to redesign its entire network just to be able to keep saying they are 4G？ Now however, they ITU has decided itself.What does this mean for carriers and users？ First，let’s see what 4G really is. As expected, LTE is central to the ITU strategy,but more precisely,the organization went with LTE-Advanced,which is a stricter version of traditional LTE. To qualify as 4G，a network has to provide 100Mbps connections over wireless,and 1 Gbps over wired. The whole network has to be fully IPv6 compliant. Frequencies have to be variable over 40MHz to avoid interference. Finally, global roaming has to be seamless, along with transitions between wirless and wired connections. This is a real step forward, and a good decision, which ensures that real 4G services will meet a good level of services. Technically, LTE-Advanced is just one of two new standard that are now under the umbrella called IMT-Advanced. The other one is WiMAX 2 which is a further refinement of the WimMAX protocol. Based on the paragraph above，to qualify as 4G, a network has to satisfy （） criteria. The transitions between wireless and wired connections have to be （）. LTE-Advanced is a standard belonging to （）.

A．two B．three C．four D．five A．limited B．possible C．seamless D．deployed A．WiMAX B．WiMAX 2 C．IPv6 D．IMT-Advanced
