About bidirectional 1:1 T-MPLS path protection, which of the following are correct? ()

A. In 1:1 mode, protection connection is specific to each work connection; the protected work service is transmitted by work or protection connection.

B.Whether work connection or protection connection is selected depends on some certain type of mechanism. To avoid single point failure, work connection and protection connection should take separate routes.

C.During the switching, APS is needed for negotiating two sides of the connection. Bidirectional 1:1 T-MPLS path protection should be revertive type.

D.1：1 T-MPLS path protection is bidirectional switching type. That is to say, connections in both affected or non-affected directions are switched to protection paths.

A new era is upon us. Call it what you will: the service economy, the information age, the

knowledge society. It all translates to a fundamental change in the way we work. Already we're partly there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the breadth of the economic transformation can't be measured by numbers alone, because it also gives rise to a radical new way of thinking about the nature of work itself. Long-held notions about jobs and careers, the skills needed to succeed, even the relation between individuals and employers--all these are being challenged. We only have to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip, would transform. our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow's achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more vital, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information services will be predominant. It will be the way you do your job.

A characteristic of the information age is that ______.

A．most of the job opportunities can now be found in the service industry

B．manufacturing industries are steadily increasing

C．people find it harder and harder to earn a living by working in factories

D．the service industry is relying more and more on the female work force

What is a Port City？The port city provides a fascinating and rich understanding of the mov

What is a Port City？

The port city provides a fascinating and rich understanding of the movement of people and goods around the world. We understand a port as a centre of land-sea exchange, and as a major source of livelihood and a major force for cultural mixing. But do ports all produce a range of common urban characteristics which justify classifying port cities together under a single generic label？ Do they have enough in common to warrant distinguishing them from other kinds of cities？

Ports and harbours

A port must be distinguished from a harbour. They are two very different things. Most ports have poor harbour, and many fine harbours see few ships. Harbour is a physical concept, a shelter for ships; port is an economic concept, a centre of land-sea exchange which requires good access to a hinterland (内地，腹地) even more than a sea-linked foreland. It is landward access, which is productive of goods for export and which demands imports, that is critical. Poor harbours can be improved with breakwaters (防浪堤) and dredging if there is a demand for a part. Madras and Colombo are examples of harbours expensively improved by enlarging, dredging and building breakwaters.

Once a port city, and always a port city

Port cities become industrial, financial and service centres and political capitals because of their water connections and the urban concentration which arises there and later draws to it railways, highways and air mutes. Water transport means cheap access, the chief basis of all port cities. Many of the world's biggest cities, for example, London, New York, Shanghai, Istanbul, Buenos Aires, Tokyo, Jakarta, Calcutta, Philadelphia and San Francisco began as ports, that is, with land-sea exchange as their major function—but they have since grown disproportionately in other respects so that their port functions are no longer dominant. They remain different kinds of places from non-port cities and their port functions account for that difference.

A truly international environment

Port functions, more than anything else, make a city cosmopolitan (世界性的). A port city is open to the world. In it races, cultures, and ideas, as well as goods from a variety of places, jostle (竞争), mix and enrich each other and the life of the city: The smell of the sea and harbour, the sound of boat whistles or the moving tides are symbols a of their multiple links with a wide world, samples of which are present in microcosm (微观世界) within their own urban areas.

Reasons for the decline of ports

Sea ports have been transformed by the advent of powered vessels, whose size and draught (船的吃水深度) have increased. Many formerly important ports have become economically and physically less accessible as a result. By-passed by most of their former enriching flow of exchange, they have become cultural and economic backwaters or have acquired the character of museums of the past. Examples of these are Charleston, Salem, Bristol, Plymouth, Surat, Galle, Melaka, Soochow, and a long list of earlier prominent port cities in Southeast Asia, Africa and Latin America.

Relative significance of trade and service industry

Much domestic port trade has not been recorded. What evidence we have suggests that domestic trade was greater at all periods than external trade. Shanghai, for example, did most of its trade with other Chinese ports and inland cities. Calcutta traded mainly with other parts of India and so on. Most of any city's population is engaged in providing goods and services for the city itself. Trade outside the city is its basic function. But each basic worker requires food, housing, clothing and other such services. Estimates of the ratio of basic to service workers range from 1:4 to 1:8.
