Chapter 1088 Internet Communication Development and Construction Strategy
Of course, the start of operation of the computer center and the use of large computers will also give birth to the rapid development of another new field in Nanshan.That is Internet technology. Actually, it cannot be said that way, because the Internet is not yet popular in China. What Jiang Chen and the others want to build and develop is just a set of local area networks within the entire Nanshan.No, it should be said to be more extensive than a LAN, and it should be called a metropolitan area network.To put it bluntly, it is the network system within a city.Although Nanshan is not too big at present, its huge development potential makes Jiang Chen and the others have to make long-term considerations.

The so-called metropolitan area network is a computer communication network established within a city, referred to as MAN, which belongs to broadband local area network.Its typical application is broadband metropolitan area network, which is a high bandwidth, multi multi-function, multi-service access multimedia communication network.The broadband metropolitan area network can meet the increasingly vigorous demand for high-speed and high-quality data communication services of government agencies, financial insurance, universities, middle and primary schools, companies and enterprises, especially the fast-growing Internet user group's demand for broadband high-speed Internet access.Local area network and larger wide area network usually serve a unit or system, while metropolitan area network serves an entire city or a region.

For Jiang Chen’s Western Industrial Company, B17 Factory, Xingmin Company, and related enterprises in the high-tech experimental zone, as well as various institutions in Nanshan, this MAN will be an important engine for their future development. Of course Yes, Jiang Chen naturally knows the huge development potential of the Internet, so he is so eager to develop the internal LAN in this region.Perhaps, under his golden finger, this place will become a center for the development of our domestic Internet in the future, driving the development of the entire domestic Internet technology and industry.And the rapid development of the Internet can also enable Western Industrial Company, B17 Factory, Xingmin Company, and related enterprises in the high-tech experimental zone to take this opportunity to carry out fundamental industrial upgrades and make them enter a new stage of development stage.Conversely, the development of these enterprises has also promoted the development and progress of the Internet.

Under the previous construction, especially Jiang Chen's vigorous development, the entire Nanshan has now formed a complete telephone network system.In fact, this set of telephone network was originally developed by Jiang Chen and his western industrial company. At that time, Jiang Chen and his company built a network covering the entire company in order to solve the connection between various factories and departments in the company's industrial park and improve communication efficiency. The internal telephone network of the factory area.Later, because of the remarkable effect, B17 factory also followed up this construction plan, and built an internal telephone network covering the whole factory inside B17 factory.Later, Xingmin also built such an internal telephone network.

Due to development needs, under Jiang Chen's organization and coordination, Jiang Chen and the others integrated the internal networks of several companies through the telecommunications company and related technical personnel, forming a huge internal telephone network system.Afterwards, the employee community, various villages, towns, and institutions in Nanshan, including various enterprises in the high-tech experimental zone, also joined this network, thus forming an internal telephone network covering the entire Nanshan area. system.For this reason, Jiang Chen and the others teamed up with the telecommunications department to set up a special internal network telecommunications management department in Nanshan, which is responsible for managing the telephone network system in the entire Nanshan area.

Of course, because it is an internal telephone network, all telephone network systems operated by external telecommunications are still different.For example, the cost of internal calls in the entire Nanshan area is very cheap. The current cost per minute is only [-] cents, which is far lower than the cost of external calls.However, if you call to the outside world, the cost will be the same as the outside world. This is a good agreement between Jiang Chen and the telecommunications department.Of course, the reason why the telecommunications side made such a big concession is that, on the one hand, most of the funds for the construction of the telephone network in the Nanshan area were funded by Nanshan itself, and of course, it was mainly borne by Jiang Chen and the others themselves.

On the other hand, Jiang Chen and the telecommunications department are cooperating in other areas.For example, Jiang Chen and the telecommunications department are currently trying to set up a wireless communication base station in the Nanshan area to experiment with related technologies in wireless telephony.Of course, in this basket of cooperation with the telecommunications sector, there are still many cooperation contents, such as using the successful research of advanced electronic components and micro-integrated circuits in the laboratories of Jiang Chen and his company, and trying to develop our country's first The wireless phone comes out.This kind of phone has been popularized in the Baodao area of ​​Xiangjiang, and it has also appeared in Shenzhu and even Yangcheng in the south and is used by a few people.This kind of wireless phone is called "big brother" in the local dialect, and we are more accepting, and it is also the name we call it most often "mobile phone".

Although mobile phones are now available in China, and the construction and promotion of wireless communication base stations are also beginning, all the relevant equipment currently used comes from abroad.In order not to be controlled by others, to avoid relevant foreign exchange outflows, but also to reduce fees and related costs, we must master relevant technologies in this field.However, through dismantling and researching the relevant base station equipment of mobile phones of many foreign mobile phone brands, coupled with Jiang Chen's deliberate "guidance", the research on this aspect of the target has made great progress, and the experimental base station samples and mobile phone samples It has come out and is in the process of testing and experimenting intensely.

With this set of completed telephone network system, Jiang Chen and the others can use this set of ready-made network system to carry out metropolitan area network modification.However, to Jiang Chen's disappointment, the previous telephone network lines, especially the main trunk lines and main branch lines, did not meet the technical requirements of the metropolitan area network.Therefore, it can only be replaced by a large twisted pair cable suitable for network data communication transmission.Of course, Jiang Chen originally planned to replace it with a more advanced optical fiber communication cable.However, during this period, there was no mature optical fiber communication cable technology for commercial operation, either domestically or internationally.After the optical fiber communication technology matures, corresponding upgrades will be carried out.

Of course, the transformation of the network lines is only the first step, and the next step is the construction of the network switch system, which is also a complex and huge project.Its specific function is like a traffic light on the road, diverting and diverting data information.And in this huge network, there are countless crossroads like this, so naturally, many network switches are needed to divert and guide the traffic.And these are not all problems, such as the relationship between switches, the relationship between superiors and subordinates, and the speed problems caused by switches. These series of problems need to be studied and solved.And because the network system is relatively large, more switches are used, which forced Jiang Chen and the others to give up importing from abroad and adopt the road of independent research and development.Of course, this plan has also aroused the interest of many enterprises and individuals, and actively invested in various projects.This includes the young Huawei company, and Mr. Ren supported by iron-blooded tough guys.
