托福听力lecture的结构1. Lecture有结构托福听力的lecture基本上都是总分总的结构,即「引入话题——展开讨论——教授总结」,下面分点论述:1)引入话题其实托福听力lecture里面讲课的教授就跟大家碰到过的老师一样,有的喜欢直入主题,有的喜欢拉七杂八。
总的说来,lecture话题的引入方式有三种:•开门见山:啥也不扯,一言不合就开车,比如TPO1 Lecture2:Ok, let’s get started. Great. Today I want to talk abouta way in which we are able to determine how old a pieceof land, or some other geologic feature is –datingtechniques.•课程回顾:回顾上堂课的内容,然后再切入本堂课的内容;一般来说本次是上次的细化或者与上次的对比。
比如TPO5Lecture2:Last week, we covered some arguments against going back to the Moon. But there are compelling reasons in favor of another Moon landing too, um…not the least of which is trying to pinpoint the moon’s age.••啰哩吧嗦:有的教授实在是特别啰嗦,比如TPO2 Lecture2:Hi, everyone. Good to see you all today.【你也好啊】Actually,I expected the population to be a lot lower today. Ittypically runs between 50 and 60 percent on the day theresearch paper is due.【来的人多不好么,说明你受欢迎啊】Um, I was hoping to have your exams back today【啊,要放榜啦】, but, uh, the situation was that I went away forthe weekend, and I was supposed to get in yesterday at five, and I expected to fully complete all the exams by midnightor so, which is the time that I usually go to bed, but myflight was delayed, and I ended up not getting in untilone o’clock in the morning【你飞机晚点关我什么事啊】.Anyway, I’ll do my b est to have them finished by the nexttime we meet【开始上课吧,please】. OK. In the last class,we started talking about...【终于开始了…】不论是用哪一种引入方式,话题总是要出来的。
3.21 Consider the M/M/1/m system which is the same as M/M/1 except that there can be no more than m customers in the system and customers arriving when the system is full are lost. Show that the steady-state occupancy probabilities are given by()m n p m n n ≤≤--=+0,111ρρρ证明:方法1, 直接使用系统状态变化的马氏链去计算方法2,可以使用截断马氏链的结果去做3.55 Consider the feedback model of a CPU and I/O device of Example 3.19 with the difference that the CPU consists of m identical parallel processors. The service time of a job at each parallel processor is exponentially distributed with mean 1/μ1. Derive the stationary distribution of the system.Solution:3.57 Consider the network in Fig 3.39. There are four sessions: ACE, ADE, BCEF, and BDEF sending Poisson traffic at rates 100, 200, 500, and 600 packets/min, respectively. Packet lengths are exponentially distributed with mean 1000 bits. All transmission lines have capacity 50 kbits/sec, and there is a propagation delay of 2 msec on each line. Using the Kleinrock independence approximation, find the average number of packets in the system, the average delay per packet (regardless of session), and the average delay per packet of each session.Figure 3.39Solution :参考P211, section 3.6.1详细过程略。

SampleJob Problems for GraduatesCollege graduates find it increasingly difficult to get a rewarding job. One reason perhaps is that many colleges and universities fail to adapt their courses to the development of economy. Second, there is an oversupply of graduates in certain specialties. What should be done to solve this problem? To begin with, the colleges should get students out of the ivory tower and have their courses meet the needs of industry and business so as to suit the on-going development of the national economy. Second, the government should provide college graduates with more opportunities to develop new skills. The third solution, I think, is to adopt strong measures of birth control because the greater the population, the less the opportunity for everyone to get a job. 作文模式Model 1: Problem-solutionWriting 12005年Directions: Write an essay of 160-200 words based on the following drawing. In your essay,you should first describe the drawing,then interpret its meaning and give your comment on it.1. 养老“足球赛”Model CompositionA “Football Match” of Taking Care of ParentsAs is illustrated in the cartoon, the four children are playing a “football match”, however, the “ball” is their old father. While the eldest son kicks his father out, his younger brothers and sister are serving as “goalkeepers”, trying to keep their father out of their “goals”.There is no denying that this picture reveals a common yet serious problem in our country. In the first place, many young people are enjoying a comfortable life, but they regard their parents as burdens. In the second place, their parents have grown so physically weak that they cannot support themselves. If their children don‟t take care of them, they will be reduced to utter poverty. Last but not least, to be kind to one‟s p arents is the height of virtue in our tradition.As far as I am concerned, we should do something to prevent such an evil phenomenon from happening again. To begin with, all the society should condemn such a wrongdoing and these children should be pun ished by law. What‟s more, every citizen must realize it is our duty to support our parents when they are old. Only with the joint efforts can we hope to solve thisproblem.Writing 2 Our Right Attitudes Toward AnimalsY our essay should meet the requirements below:1)Describe the cartoon and deduce the purpose of the drawer of the cartoon;2)State the negative effects of eating wild animals; and3)Give your suggestion as to how to solve the problem.As is depicted in the cartoon, both the cat and snake are on the table, with tears in their eyes, waiting to be eaten by humans. Through this picture, the drawer condemns the eating of wild animals and calls for our sympathy for and protection of them.Eating wild animals gives rise to a lot of negative effects. In the first place, as many wild animals carry viruses or parasites, when we eat them,the viruses or parasites enter our bodies,thus causing a lot of illnesses. The severe acute respiratory syndrome is a case in point. It was reported that the virus derived from a “delicious” animal and the disease has claimed thousands of lives throughout the world and brought great damages to p eople‟s properties. In the second place, since animals are an indispensable part of our environment,the extinction of some animals may disturb the natural balance. Last but not least, eating wild animals is cruel. After all, wild animals are our close friends.Since eating animals causes so many harms,we should work together to put an end to the problem. On the one hand,the government should make stricter laws to prohibit people from eating wild animals,just as our government has been doing. On the other hand, all the people should realize the harms of eating wild animals and refrain from doing so. Only through these measures can we hope to solve the problem.Writing 3There is a discussion in the newspaper about the employment problems of college graduates. According to a recent survey, many graduates will be unable to find a job. Y ou should write a letter to the newspaper to1)Explain the statistics in the table;2)Give the reasons for the phenomenon,and3)Propose your suggestions as to how to solve the problem.Employment Problems of College GraduatesAs is demonstrated in the table, more and more college graduates are out of a job in our country,which is a serious problem to our economic development and social security as well as a hindrance to our building a “harmonious society”. It is estimated that in 2005, there will be 1,000,000 unemployed graduates, more than twice the number in 2002.There are several reasons for this phenomenon. In the first place, as the enrollment of college students has grown by more than 30% annually since 1998, more and more students are thrown into the labor market. However, our annual GDP growth has been about 8%. Therefore, the supply of labor exceeds the demand, hence a shortage of positions. In the second place, many graduates do not want to work in medium-sized and small cities or towns where they are most needed. Instead, too many of them crowd in big cities like Beijing, Shanghai or Guangzhou. Last but not least, the knowledge of many students is out of date. As a result they cannot meet the requirements of the factories and companies.Serious as the problem seems, we can come up with some measures to deal with it. On onehand, the government should develop our national economy more rapidly, creating more job opportunities. On the other hand, the college students must be realistic in choosing jobs. It is reported in the newspaper that many graduates went to the West of our country to pursue their career in 2003. With the joint efforts of all of us, the unemployment problem will surely be solved soon.Writing 4 2000年Y our essay should meet the requirements below:1) Describe the pictures.2) Deduce the purpose of the drawer of the pictures.3) Suggest counter-measures.As is shown in the pictures, we can see clearly that with the increase of commercial fishing, the number of fish sharply decreased. In one picture, there were various kinds of fish and only one fishing-boat in 1900. On the contrary, in 1995 there was only one fish, but many fishing-boats.The purpose of this picture is to show us that due attention has to be paid to the decrease of ocean resources. Owing to over fishing, the number of fish has obviously dropped. If we let this situation go as it is, we won…t know where fish is in the future. By that time, our environment will suffer a great destruction.Therefore, it is imperative for us to take drastic measures. For one thing, we should appeal to our authorities to make strict laws to control commercial fishing. For another, we should enhance the awareness of people that the ocean resources are vital to our survival. Only in this way can we protect our ocean resources. Also, I believe that we human beings can overcome this difficulty, and we will have a bright future.Writing 5The Harmfulness of Smoking1)Describe the cartoon;2)State the harms of smoking;3)Give your suggestions as to how to solve the problem.As is shown in the cartoon, when the man is enjoying the cigarette, the smoke becomes a monster which will devour him. This picture tells us vividly that smoking is harmful to people.The harmfulness of smoking can be illustrated in three aspects. To begin with, smoking does harm to people‟s health. It is common k nowledge that many deadly diseases derive from smoking. Take my neighbor, Lao Wang, as an example. He has been smoking cigarettes for nearly 30 years and during the recent check-up, doctors told him that he suffers from lung cancer. His days are numbered. Much as he likes smoking, he decides to give it up to stop the illness worsening. In addition, smoking costs a lot of money. It is estimated that tens of billions of yuan is spent on cigarettes every year in our country, which is a huge waste. Last but not least, smoking may cause fire. Do you still remember the big fire in the Northeast of our country which caused serious damages to people‟s lives and properties?Serious as the problem seems, we can come up with some ways to deal with it. For one thing, the government should make stricter rules to prohibit smoking in public places, imposing higher fines on smokers. For another, all the smokers should give up smoking for the sake of themselves and those around them.Writing 6 1998年Y our essay should meet the requirements below:1) Write out the messages conveyed by the cartoon.2) Give your comments.Model Composition lThe past several years have witnessed a phenomenon that a variety of promises have been arising from all walks of life. Regrettably, quite a lot of promises are sheer nonsense, just as the hen in the given cartoon commits herself to laying eggs which are round without any angles and corners and have shells, egg whites and yolks.Odd and funny as they sound, such false promises can be seen and heard everywhere in our country. Administration departments claim to perform their tasks effectively and fairly without taking any bribes; manufacturing units guarantee to turn out products of good quality; commercial enterprises swear to provide genuine commodities and enthusiastic services. Can you find anything new and substantial other than their obligations,duties and jobs in these so-called promises? I guess your answer will be negative. As a matter of fact, their intention to make such commitments is nothing but to put on civilized outer clothing to please or deceive the public.I dare say that our society is suffering corruption and cheat which are causing damage to society both materially and morally. But the hen and her like should know that by dishonest words no one could survive the intense competition in the market economy. They should remember the old saying,"Honesty is the best policy".Model Composition 2Here is an interesting cartoon: With her head held high, maybe singing, a hen stands proudly in the center of the picture with a notice in her hand, which says that she promises to lay eggs that are like any normal egg. It…s so ridiculous that we can…t help laughing. But after that there must be something for us to think.Recently, many promises have come up in many walks of life, especially in the service departments. They promise that they will provide you with warm smile service and good products. At first you are moved nearly to thank them. But if you think twice, you may wonder if those should be their duties. It goes without saying that factories should produce goods of quality; department stores should serve customers politely; buses should arrive on time, and so forth, because all of these are their responsibilities. But why should they promise what are their due jobs? One reason may be that they want to correct their past mistakes under the planned economic system. Another reason is that they intend to improve their images and please the customers.In my opinion, trying to be better is worth welcoming, but making empty and false promises is unacceptable. If factories, companies, stores and administrations do their jobs well rather than talk nonsense, our society will be more prosperous.Writing 7Homework1) Give your understanding of the symbolic meaning of the picture;2) State the harms of the phenomenon;3) Tell how to solve the problem.As can be clearly seen from the cartoon, the mahjong pieces occupy most part of the desk, while a book, an exercise book and a pencil box lie at the corner. This picture vividly tells us how poor the condition is for the child to study.This phenomenon gives rise to a lot of negative effects. In the first place, while the parentsare playing mahjong, they make a lot of noise, which disturbs the child‟s study. How can a child concentrate on his study in such a poor condition? In the second place, the child will have no place to study if his parents spend all day playing mahjong. However, time is crucial for him to acquire the knowledge, because “Practice makes perfect”. Last but not least, the child will learn to play mahjong from his parents. Just as the old saying goes, “Like father, like son”, so the child will abandon his study and be a gambler like his parents.Serious as it seems, we can think of some measures to deal with the problem. To begin with, the government should make stricter rul es to prohibit parents from playing mahjong. What‟s more, the parents should give up playing mahjong for their child‟s sake.Writing 8 How Can Laid-off Workers Find New Jobs?1.很多下岗工人很难找到新的工作。

CHARPER 12a. Describe what step-by-step procedure might be involved inside the network in making a telephone connection.Solution:1. The telephone number specifies an "address" where the receiver is located.e.g. 025 - the area code ( geographical region); 8349 - telephone office ;2480- theparticular location of receiver.2. Telephone number dialed, route determination , circuit established.3. A ringing tone of incoming call at destination;The setting up of telephone calls is discussed in Chapter 4.Reference : P8 Figure 1.5 the three phase of a telephone connection2b. Now consider a personal communication service that provides a user with a personal telephone number. When the number is dialed, the network establishes a connection to wherever the user is located at the given time. What functions must the network now perform in order to implement this service?Solution:personal telephone number is not tied to a specific location, instead associated withan equipment. Fixed location telephone number cannot establish a connection towherever the user is located at the given time.Reference: a cell phone. GSM.3. Explain how the telephone network might modify the way calls are handled to provide the following services:a. Call Display: the number and/or name of the calling party is listed on a screen before thecall is answered.Solution: Along with the request for connection setup, the system sends identifying information regarding the originator's phone.5. Suppose that network addresses are scarce, and are assigned, so that they are not globally unique; in particular suppose that the same block of addresses may be assigned to different organizations. How can the organizations make use of these addresses? Can users from two such organizations communicate with each other?Solution:1. unique address within the same organization, but no unique address across multipleorganizations.2. establish gateways to connect between their internal users and users in other networks.Globally gateway unique address across multiple organizations..10. Discuss the similarities between the following national transportation networks and a communications network. Is the transportation system more similar to a telephone network or to a packet network?Solution:Comparison: connection oriented or connectionless.Application: people and goods.14. The propagation delay is the time that is required for the energy of a signal to propagate from one point to another.a. Find the propagation delay for a signal traversing the following networksb. How many bits are in transit during the propagation delay in the above cases, if bits areentering the above networks at the following transmission speeds: 10,000 bits/second; 1 megabit/second; 100 megabits/second; 10 gigabits/second.Reference: delay-bandwidth product.15. IETF, RFC, internet Draft , Proposed Standard, Draft Standard, and StandardCHAPTER23. What difference does it make to the network layer if the underlying data link layer provides a connection-oriented service versus a connectionless service?Solution:1. connection-oriented: network layer setup connection before transfer of information. Framesare transferred correctly and in sequence by the data link layer, the network layer can then assume that the packets it sends to its neighbor traverse an error-free pipe.2. connectionless: Each frame is sent in unconfirmed manner (without acknowledgments orretransmissions). Network layer cannot make assumptions about the sequencing orcorrectness of the packets it exchanges with its neighbors.4. Suppose transmission channels become virtually error-free. Is the data link layer still needed?Solution:Framing, Flow control, MAC.5. Why is the transport layer not present inside the network?Solution:1. Providing functions compensation for the upper layer of end-system. In TCP/IP, IP - onlybest effort service. But TCP - reliable service required by applications2. connections establishment and error control on an end-to-end basis / at the edge ofnetwork.3. Allow multiple processes in the end systems to share a network service.10. Give two features that the data link layer and transport layer have in common. Give two features in which they differ. Hint: Compare what can go wrong to the PDUs that are handled by these layers.Solution:In common: recovery from errors; flow control; multiplexing.Difference:1. across the network vs. connected directly; so other different feature induced.2. framing vs. block/ byte stream.3. MAC11a. Can a connection-oriented, reliable message transfer service be provided across a connectionless packet network? Explain.Solution:e.g. transport layer →logical connection →by setting up state information →e.g. packetsequence number →provide transmission with error free, no duplication, in order.e.g. TCP/IP22. How does the network layer in a connection-oriented packet-switching network differ from the network layer in a connectionless packet-switching network?Solution:24. Suppose we need a communication service to transmit real-time voice over the Internet. What features of TCP and what features of UDP are appropriate?Solution:TCPAdvantage: connection-oriented service for real-time voice stream.Disadvantage: reliable service with retransmissions results in packet delay and jitter that can not be tolerated by real-time traffic.UDPFeature: Provides connectionless service and delivers packets quickly. On retransmission, but some degree of packet loss can be tolerated by voice.28. What is the difference between a physical address, a network address, and a domain name?Solution:See PPT or textbook.Which is used in the data link layer?Which is the logical address?Which is the name easier to remember?33. Suppose a computer is moved from one department to another. Does the physical address need to change? Does the IP address need to change? Does it make a difference if the computeris a laptop?Solution:Key: Globally unique NIC card, IP address→sub-network id and host id.CHAPTER 411.

STS-1 51.84Mbps; STS-3 155.52Mpbs; STS-12 622.08Mbps; STS-48 2.5Gpbs; STS-19210Gbps.25. Compare the operation of a multiplexer, an add-drop multiplexer, a switch, and a digital crossconnect.Solution:1. multiplexer, add-drop multiplexer reference to PPT or textbook2. switch-N inputs ×N outputs. (1) Each input to a switch contains a number ofmultiplexed connections. (2)These connections can be demultiplexed and routed to different output ports where they are aggregated prior to exiting the switch. (3)switches are configured using signaling3. digital cross-connect is similar to a switch except that it is semi-permanent, usuallyconfigured by network operators rather than signaling processes. Their configuration is also done on a larger time scale (days or weeks). Digital cross-connects provide a basic network topology on which routing can be applied.27. Consider the multistage switch in Figure 4.35 with N = 16, n = 4, k = 2.a. What is the maximum number of connections that can be supported at any given time?Repeat for k = 4 and k = 10.Solution:For N = 16, n = 4 and k = 2, we have the following switch architecture:(1)Find the bottleneck. k<2n-1 8connection at a time(2)If k=4, k<2n-1, unblocking if rearrangement the connection pattern every time a newconnection request is made. But blocking in other situation. 16×16(3) if k=10, k>2n-1, without blocking.b. For a given set of input-output pairs, is there more than one way to arrange theconnections over the multistage switch?Solution: k ways →number of mid-stage switch29. Consider the multistage switch in Figure 4.35 with N = 32. Compare the number of crosspoints required by a nonblocking switch with n = 16, n = 8, n = 4, and n = 2.Solution:non-blocking →k = 2n – 1;total number of crosspoints →2Nk + k(N/n)2.49. Explain where the following fit in the OSI reference model:Solutions:a. A 4 kHz analog connection across the telephone network.Physical Layer: analog signal exists only in the physical layer.b. A 33.6 kbps modem connection across the telephone network.Data-Link Layer: modem uses framing, flow-control, and error correction, MAC.c. A 64 kbps digital connection across the telephone network.Physical Layer: 64 kbps signal is analogous to the 4 kHz signal used over the twisted pair.CHAPTER 51. Explain the difference between connectionless unacknowledged service and connectionless acknowledged service. How do the protocols that provide these services differ?Solution:(1) acknowledged connectionless service: reliable delivery for upper layer; Application forsensitive to loss; underlying layer is inherently unreliable with high BER.(2)Unacknowledged connectionless service: simpler and faster communication; Applicationfor inherently reliable networks or higher layers that can tolerate information loss or higher layers built-in error recovery mechanisms.10. Discuss the merits of the end-to-end vs. hop-by-hop approaches to providing a constant transfer delay for information transferred from a sending end system to a receiving end system.Solution:Jitter in networks has two primary sources – variation in queuing delay and variation inpropagation delay.Hop-by-hop approaches can be used to deal with queuing delay variation, and end-to-end approaches are required to deal wit h path-length variation.23. see textbook P30640. P31852. Perform the bit stuffing procedure for the following binary sequence:1101111111011111110101 →11011111011011111011010153. Perform bit de-stuffing for the following sequence:11101111101111100111110 →111011111-11111-011111-54. Consider the PPP byte stuffing method. What are the contents of the following received sequence of bytes after byte destuffing:0x7D 0x5E 0xFE 0x24 0x7D 0x5D 0x7D 0x5D 0x62 0x7D 0x5E →0x7E 0xFE 0x24 0x7D 0x7D 0x62 0x7E68.For this question, one must just keep in mind that all frames always contain the address of the secondary station.Only C is right!CHAPTER 631. Use HDLC and Ethernet to identify three similarities and three differences between medium access control and data link control protocols. Is HDLC operating as a LAN when it is used in normal response mode and multipoint configuration?Similarities: Both medium access control and data link protocols deal with the transfer ofblocks of information across a “single hop” which can consist of a point-to-point line, amultipoint line, or a shared medium.…… look up in textbookDifferences: The main functionality of the MAC protocols is to coordinate the access ofmultiple nodes to a shared transmission medium. To do so, the MAC protocols implement contention resolution procedures.The data link layer protocols implement error control and flow control functions to provide reliable transmission. The MAC protocols do not implement these functions.The data link layer protocols such as HDLC are concerned with providing connection-oriented, connectionless, and acknowledged connectionless packet transfer services to the network layer. The MAC protocols only provide connectionless packet transfer.The data link control protocol often handles packet transfer only over a point-to-point link between two nodes, where medium access control is not required. However, themultipoint-to-point configuration is an exception. When HDLC operates in normal response mode, it in fact is implementing polling to control access to the medium.36. Suppose that 80 percent of the traffic generated in the LAN is for stations in the LAN, and 20 percent is for stations outside the LAN. Is an Ethernet Hub preferable to an Ethernet switch? Does the answer change if the percentages are reversed?The difference between a hub and a switch is that in the hub frame are broadcast to all lines, while in a switch, frames are forwarded to another collision domain only if the destination is in that domain.……42. Use IEEE 802.3 and IEEE 802.11 to discuss three differences between wired and wireless LANs.Error rate: high error rate due to interference and noiseStation mobility: stations ~ mobile and portable; dynamic traffic routing and service handoff ~ since the station moves from one service area to another.Collision detection: hidden station problemSecurity: wireless LAN ~ encryptionPower consumption: battery ~ limited power capacity ~ power efficient.47. Why is error control (ARQ and retransmission) included in the MAC layer in IEEE 802.11 and not in IEEE 802.3?reference to solution 42Chapter 77.3. Suppose a service provider uses connectionless operation to run its network internally. Explain how the provider can offer customers reliableconnection-oriented network service.1. establish logical connections before transportation2. packet sequence number →retransmit lost packets, delete duplicate packets, andrearrange out-of-order packet7.23. Consider the operation of a packet switch in a connectionless network. Whatis the source of the load on the processor? What can be done if the processor becomesthe system bottleneck?。
