Political Consultative Conference, said the computer is free to perform their duties need to send

With the "members of the Office platform," the proposal may be submitted year round active inter-State affairs

CPPCC members this year will no longer be issued laptop recovery hot lead, the CPPCC session, the secretariat and technical support group leader, director of the CPPCC National Committee General Office of the Information Center has an exclusive interview, Zhang Shan, to respond to this matter. Zhang Shan said that this was a regular member to perform their duties, the need for normalization.

Procurement of about 10 million yuan

According to "Guangzhou Daily" reported the CPPCC National Committee member Zhang Xiaomei recently revealed in the micro-Bo, "when reporting to each member received a new computer, and unlike last year, this year no longer need to return the computer after use, this should actually be more. "

"At that time the staff tells me that this one does not have recovered this year. Because last year to recover, so I just feel a bit surprised." Xiao-Mei Zhang told reporters. She is also micro-Bo wrote, "last year to return the computer does not make sense to have a computer too lazy to re-familiar with the new computer a few days without the hair he will not use your end of the meeting is indeed recovered thousands of computers is a waste. Members made the computer network and electronic office will promote awareness. "

CPPCC notebook users do not recall caused great concern. Some Internet users is estimated that the costs of procurement by 5,000 yuan each to project, more than 2000 computers need about 10 million yuan. However, some netizens said that the statements were not recovered after the convenience of members is to work, "20 years ago meeting fat pen, 20 years after the meeting made computer" is the same reason.

If do not need to be returned to the computer

Zhang, said that by early this year, members of the CPPCC National Committee established a network of office platform, which is a service-oriented work of the CPPCC National Committee members of the platform. In addition to the plenary session can be provided to members of the office of information services, after the closing plenary session, members can still be dispensed by the identity of digital certificate, all-weather access to "members of the Office platform," to achieve the file transfer, read and download, daily information CPPCC browsing, and work-related information query, the discussion among members and exchange functions. More importantly, the members of the perennial proposals submitted through the Internet, conference speeches, research reports and offer advice and suggestions, reflecting the popular feelings, so that the general members meeting is no longer a "member" and thereby members to perform the functions of a regular, normal , might be "all weather" to give full play the main role in the plenary session for further inter-active work of members of political participation. Therefore, after this time, members can be held by the computer back to work, perform their functions for the inter-sessional work, and continue to use the meeting in the series. "If the members of the allotment without meeting the computer, the computer can be returned, we will further fully to play the role of these computers." Zhang Shan said.

Zhang Shan introduced the great efforts to strengthen the information construction work of the CPPCC, the CPPCC is to promote the scientific work necessary requirement. In recent years, the CPPCC National Committee Office information technology breakthrough has been made, received solid results. The members of the applications, the second plenary session in the last year the implementation of electronic reading, based on three meetings this year to perform their duties in full swing application. As the afternoon of March 7, in 5430 the proposal in 1903 by members of the Office platform, online submission, addressing the General Assembly in 758, there are 485 members of the Office platform through the Internet, there are 56 social conditions and public opinion, 26 work proposal is submitted by members of the online office platform.

Rooted in the free soil-FastCGI

Linux as a representative of free software, to bring the IT industry, infinite space for development. Linux, transparency, both to the developer or the application of staff have a full room, in order to Linux operating systems and platforms, more features are being constantly developed. Like Server Push, FastCGI, EPERL, PHP3, and many new features, such freedom is in the soil of Linux to the full development.
The performance of a website, mainly in the following areas: system response time, processing time, user waiting time and system output load, considering the economic factors but also with technology costs. To improve the performance of the site, without changing the hardware and network architecture based on the technical content of the concentrate so good procedure. At present, Server Push (push technology) and FastCGI two new technologies do not increase in the cost basis can make your site the best performance. This article details FastCGI technology.

What is FastCGI

To show that if you want to use FastCGI, you should Linux-operating system services build FastCGI Apache module, you can go to www.fastcgi.com to download the latest module, download the module will be compiled detailed description .

Over the years, CGI has become a server-side application development, the de facto standard, although the emergence of ASP technology to enable server-side application development easier, but ASP still limitations to the current Unix / Linux as the operating system and use Apache to serve The server refused to process the vast majority of its door, CGI is still singing the server-side application development in the main event. Over time, many of the server under the heavy burden of CGI is now insufficient.

Let us see how the CGI work in it: when the client requests the server CGI application, a process server to handle user requests, after the end of the process. When the load is very low, CGI can work well, but the site of a large variety of different types of requests occur at any time, in the client request load is high, the server process setup and initialization time used a web site performance bottlenecks. In particular, such as application and database connection, initialize longer used.

When the FastCGI technical stand out often, this problem has been well resolved. FastCGI is active at a request from the server to provide services. FastCGI is a server running a "campaign of procedures" to handle server requests the application program's. FastCGI is always active, this is of benefit, it does not start in dealing with requests O'clock Xin Jin Cheng, and on the initial application of overhead. server-side can use PERL, C, C + + or JAVA and other languages to write one based FastCGI application to constantly deal with server application request. particularly for Server Push this connection, the server Otherwise intermittent response to user requests, we must continue to allow the server application is running to support the application request.

The advantages of FastCGI


We know, CGI can not be used as cache memory, because it run once for each request an application, and quit after the completion of the task. The FastCGI can be effectively used as cache memory to greatly improve its performance to process the request. Separate FastCGI applications and CGI than, perhaps not a good use of cache, and once FastCGI is designed to be multi-threaded, it can handle multiple requests to run concurrent application process, so that the process of multiple threads can share memory and access the same cache.

Another major advantage of FastCGI is that it can use a distributed network system to complete large-scale systems integration. A website to complete the user's interaction requirements, at least with e-mail, BBS and chat rooms these three functions, taking into account data security and database capacity and other factors, very few sites have all the data on the same host on. We all know that, because the process of environmental reasons, the server can call the machine CGI application, which hosts the distributed system to bring more limitations. The FastCGI applications do not get the CGI environment from a process variable, but in the FastCGI application and the server to create a "full duplex" connection, transmission of environmental information, STDIN, STDOUT and STDERR. So that we can place the FastCGI application in another host, using TCP / IP protocol and the main server remote connections. In the main server FastCGI application can request the same as the local machine to respond. The advantages are:

1. Can expand the size of network system

2. Can reduce the load on the same server

3. More servers can share the same FastCGI application.

How to write FastCGI applications

Let us first look at how the running FastCGI:

As you can see, like, FastCGI in dealing with a request to continue to run, so that the new request comes immediately to process the request. So FastCGI programs typically include the initialization code and packaging process of the main section of the response cycle, of course, after initialization, the main program loop to run continuously waiting for the arrival of the request. Only in the FastCGI application is withdrawn when the cycle until the end of the system.

Another advantage of FastCGI is shifted from the CGI FastCGI is simple, let's look at a traditional CGI:

Example 1: NUMBER.CGI

#! / Usr / bin / perl

# Variables

my $ End = 10;

my $ i;

# Content Header

print "Content-type: text / html; CHARSET = gb2312n";

# Main loop

for ($ i = 0; $ i <$ End; $ i + +)

(Print "$ i
;)

exit 0;

The CGI in the browser page on each line from 1 to 10 of a digital display.

Let us look at how to use FastCGI to write this program:

Example 2: NUMBER.FCGI

#! / Usr / bin / perl

# In order to use FastCGI package, need to add the following statement:

Use FCGI;

# Initialize the initialization section of the same section and CGI.

# Variables

my $ End = 10;

my $ i;

while (FCGIaccpet ()> = 0) (

# Content Header

print "Content-Type: multipart / x-mixed-replace; boundary = BOUNDARYnn";

# Because each request must have the appropriate Content-Type header in response, so we put it as a response to the main loop code.

# Main loop

for ($ i = 0; $ i <$ End; $ i + +)

(Print "$ i
;)

)

exit 0;

Because FastCGI and server applications, like running, so only the end of the signal received when the FastCGI only exit, otherwise it has been run.

Although the shift from the CGI FastCGI is very easy, but in practical examples of we have to note, if the original could cause the CGI program in the main code does not loop running code, you must modify it, that is Some variables, re-initialize the array. FastCGI application must ensure that in dealing with any request, any existing state can impact on subsequent requests. In addition, the programmers writing CGI programs, the modular design allows the main program running on those who do not frequently use the function modules relative "independence", and only when needed to be transferred to run, so you can speed up the main program operation. but turned FastCGI application process to be considered as a paragraph in the completion of related functions, in order to reduce the process to run when the number generated, and procedures between the various functional blocks can fully shared cache.

Beijing-Shenyang Expressway: Breaking the "separatism," the first

Middleware in the Beijing-Shenyang project application, for our inter-provincial highway network management is of great significance.

In our increasingly dense network of road transport today, the construction of highway is no longer any news, but in October 20, 2003, Beijing-Shenyang highway officially opened on interconnection charges when many of the media on the incident the unprecedented magnitude of pages to full coverage. What attracted them to a road so concerned about?

658 km on the road of four "mother"

As a heavy industry base in Northeast China and the connection between the capital, Beijing, an important transportation route, Beijing-Shenyang expressway opened to traffic in 2000, through Xianghe, Hebei Province, Tianjin Baodi, Hebei, Tangshan, Qinhuangdao, from Liaoning, Jinzhou, length 658.7 km.

658 km is not long, however, been different roads into the beginning of the investment units "cut" to 5, paragraph into Beijing, Langfang section, in Tianjin, Hebei and Liaoning Shenyang Baoshan segment Hill section, each by different owners to charge management. More intensive in the pay site to Shanhaiguan section of Beijing, 298 km of expressways total of four mainline toll stations, the average distance is only 74.5 kilometers, of which the shortest distance is only 15.8 km toll station.

Charges direct result of intensive site so that delayed the passage of time passing vehicles. It has been for a survey, from Shenyang, Beijing-Shenyang Expressway to go to Beijing to go through three port charges, parking access card, and paid a total of 6 times. Car is low, through the charging port to be delayed 23 minutes; case of vehicles, you need to spent 56 minutes, or even longer, high-speed into the fast, slow, motorists grumbling!

In fact, this not only to high-speed Beijing-Shenyang so. As the investment system, management system, and many other reasons, our highways are basically sub-building, the way a company, decentralized management. Highway Mileage in China and gradually increasing through the case of a network, the management of this sub-state separatism, on the one hand seriously affected the unity of the road network; the other hand, increased management costs. If some parts of the same route more than a joint venture co-exist, independent of each other, segment fees, resulting in the main line station to set off close, affecting smooth.

To break the drawbacks of a decentralized management highway, in October 2000, the Ministry of Communications issued a "provisional toll highway network technical requirements", and was held in November 2000 after high-speed Beijing-Shenyang four provinces of the departments concerned to study the coordination hope to conduct the first high-speed Beijing-Shenyang Expressway inter-provincial interconnection fee pilot, early in March 2003, all charges on Beijing-Shenyang Expressway Network programs 11 issue of consensus.

After the Beijing-Shenyang highway network in accordance with the "full range of networking, partition settlement," the implementation of the retention of Xianghe, Shanhaiguan two main line stations, Baodi, Hebei, and Shenyang West Point station was withdrawn in building the main line toll Shanhaiguan and 10000, a stand two points each on behalf of the issuer. The key is that the proposed scheme in Beijing to set up networking Shanhaiguan section of a profit-sharing fee settlement center, the charges section of the balance sheet included in Liaoning Liaoning Provincial Expressway Toll profit-sharing system, that is, only the owner on the highway pay a fee, as to how or by transport within the department resolved.

Middleware surface

As the networking system transformed by the Drive, charging station, charging sub-center, clearing house four system components, Drive through the original records will be on communications systems on a distributed system, import on a database. Between all levels of an independent to do this, the original records, statements to the center after the settlement. In addition, the higher command and configuration information needed by the command and communication system configuration information will be issued one level to the next level of the system, deployed to each Drive.

Beijing-Shenyang Expressway Toll therefore adopted highway network is different from other provinces charge current technical route, using cross-platform "data exchange communication middleware" technology, in the use of the existing toll collection system in civil engineering, piping and equipment based on , on the part of the Drive devices and equipment for road charging management reform, and to retain full use of existing mechanical and electrical systems software and hardware facilities, to maximize the protection and use of various sections of the investment the owners have to save the cost of the reconstruction project associated fees to technology in exchange for benefits.

In this process, the Wei guarantee both the security and reliable operation of the module, middleware of middleware products and development of the Chang Shang set out three requirements: First, the system stability and reliable sources of Chuan Shu; Second, both Tai concurrent systems Yao data processing and large data capacity of long transmission; Third, taking into account the significance of Beijing-Shenyang expressway and future management model, requires a system development cycle is short, and has high flexibility, scalability and manageability.

Contractor in the project - Beijing Public Kefei Da Traffic Engineering Development Co., Ltd. anxiously looking vision, TongTech's messaging middleware product TongLINK / Q gradually IBM and BEA and other international manufacturers fierce competition. According to TongTech Heqing Niu, deputy general manager, said: "Highway Toll System requires 7 脳 24-hour operation, requiring network communication module to ensure the smooth operation of payment system. Our more mature messaging middleware products, in the telecommunications and finance have years of experience, followed by refinement to the transport sector, we also have high-speed, Jilin, Guangdong high-speed and many other success stories, especially in Jilin high-speed, in charge of China's highway network application middleware in the first 1, has a strong representative of significance. "

180 days into highly efficient and stable network system

Beijing-Shenyang expressway network project from design to completion of charging only a short period of 6 months, head of Su Xiaoming said - "It is because of messaging middleware as the application provides an easy interface, shielding the complexity of network programming, so big improve the speed of the application system development, but also a reliable, stable and efficient network services. "

TongTech TongLINK / Q for the application provides an easy to use, efficient and reliable platform for distributed development and operation. Using TongLINK / Q can be easily and rapidly design and develop reliable and efficient with the needs of distributed applications. It also provides a distributed application management platform, it adopted the name of service and application management, provides management and monitoring of distributed applications. TongLINK / Q system to the physical network node to determine each point (network and access equipment), and through the node configuration to build the relationship between these nodes to form the logical tree or mesh network communication structure. Since each node in the logical network different positions, in order to be more easy to control these nodes, thus giving different types of each node to form a different node levels. This is entirely similar to our current executive-level classification processing, image and easy to use.

In this 180-day project implementation, the East through messaging middleware to be deployed to each transfer node, the total center of charges on sub-centers and toll stations. Various toll stations and the total center Yutian directly connected, through the middleware original records in all toll lanes on the hair directly to the main center Tamada, and the record copy to the sub-centers at all levels. Middleware between the underlying systems and applications, by calling the transmission interface message transmission, so the network problems on the screen below the middleware layer, the application can be more work to go into business processes .

In addition, the data transmission network system, the large amount of cash, and have inter-provincial coordination, harmonization split features, the system needs to ensure that the transmission of data can be subject to all kinds of unexpected failures (such as network disconnection, machine off electricity failure), can still be a reliable message transmission. Using TongLINK / Q build the underlying data transmission platform, data can be transmitted through the establishment of each node in the message queue for reliable storage and delivery, if there is downtime or network failure, etc., the data can be restored in the system and network reliable transmission of data makes the interconnection charges can not lose, no powerhouse sent to the destination.

As high-speed Beijing-Shenyang Tianjin-Tangshan Economic Zone is located in the special geographical reasons, plus the after transformation Xianghe station has become the largest country highway toll station, all the time up there a lot of data concurrency, which requires system has the ability to handle large concurrent data.

Heqing Niu, said deputy general manager, in the initial design process has been full consideration to this point, Sui Zhao Beijing-Shenyang highway traffic volume of Buduanzengjia, Shoufeixitong Yao Liang of its business would be corresponding increases, mainframe handling capacity may be difficult to meet the business processing requirements. Based on the East through messaging middleware TongLINK / Q interconnection fee system without affecting the normal operation of the system under the premise of dynamic add, delete sub-center fees, toll station node; dynamically modify service process scheduling strategy, adding new services, etc. improve the system flexibility and scalability.

September 20, 2003, the expressway from Beijing to Shenyang, the official opening of full interconnection charges, Beijing-Shenyang high-speed implementation of the "smart card." This was the opening of the first inter-provincial highway network charges, which marked China's inter-regional expressway from the inter-provincial city to the sub-management integrated management changes.

Beijing-Shenyang expressway network toll projects have been built, broke the separate management of highway management style, improve traffic efficiency and reduce operating costs. FENG Zheng-lin, as Deputy Minister of Communications pointed out that in the future, the Ministry of Communications will focus, Beijing, Tianjin and Yangtze River Delta national trunk road network charges, the eastern provinces to try to achieve in the province during 2005 all of the objectives Highway Toll .

"In the Beijing-Shenyang high-speed project, we have gradually assumed Hebei, Jiangxi, Beijing, Sichuan, networking and a series of highway toll project." Niu said Heqing vice president. The field of middleware in the domestic transport market, have occupied the top spot in the East through. In addition to highway outside the East through the Ministry of Transportation Maritime Administration also bear the "Water Safety monitoring information system" construction, and is prepared to traffic in the city of ITS, Metro AFC System and other traffic areas around attack.
