● The metric assigned to each network depends on the type of protocol. Some simple protocol, like RIP, treats each network as equals. The （71） of passing through each network is the same; it is one （72） count. So if a packet passes through 10 network to reach the destination, the total cost is 10 hop counts. Other protocols, such as OSPF, allow the administrator to assign a cost for passing through a network based on the type of service required. A （73） through a network can have different costs (metrics). For example, if maximum （74） is the desired type of service, a satellite link has a lower metric than a fiber-optic line. On the other hand, if minimum （75） is the desired type of service, a fiber-optic line has a lower metric than a satellite line. OSPF allow each router to have several routing table based on the required type of service.

问答题Practice 2 A: What is important when...? Choosing a business-training course ●Fees ●Size of group ●Subjects covered B: What is important when...? Choosing a magazine to buy regularly ●Contents ●Cost ●Printing quality正确答案： 【参考范例】
If you choose A:
When choosing a business-training course, first of all I’d like to see if our company could afford the expenses. If the business training course is too costly, the company will have to reconsider the value and effect of that course.
In addition, the size of the goup shoud also be considered. If I were the decision-maker, I would select a small-sized group. Size of group will determine the quality of training to a great extent. A small group will provide each trainee with more opportunities.
Subjects covered also need to be noticed. If the training course covers a wide range of subjects, it will be instructive for the trainees in different aspects, since the more subjects are covered, the more knowledge they will gain.
If you choose B:
When choosing a magazine to buy regularly, contents are the first thing to consider. It is for sure people will look at what’s in a magazine before they decide to buy it. To a large extent, the quality of a magazine depends on its contents.
Another factor is the cost. The cost of a magazine will stir up warm response from the market. If the cost is relatively lower than that of the same category, as a rule, readers would prefer the cheaper one.
In addition, printing quality is the face of a magazine. Generally, copperplate printing is widely applied to high grade magazines, for low cost plain paper would downgrade their images.解析： 暂无解析 -
