XML encounters performance bottleneck "weight loss" will increase transmission speed?

CNET Technology Information Network January 14th International Report XML technology has become a nearly common information sharing method of the Internet, but people are increasingly aware that the interests of XML bring a price: low performance.

This issue is undergoing efforts to accelerate XML data traffic. Supporters said that the smaller XML can accelerate the speed of all online activity, including data exchange between Internet services to mobile phone, but the industry has not yet agreed to agree.

The problem is: According to the current XML standard, all information will be stored as a text format, which means an XML document such as an order or web page, which is easy to be easily seen or by a computer via a text editor or an XML editor. Read.

Performance issues come from "spleen" of XML to create large files. Part of the reason is that the XML format requires each element in the document to be identified by the label in the text format. In addition, XML-based protocols called web services also generate a large number of XML traffic. Jeff, the technical director of Leader Technology, said XML files not only lengthy, but it also sends actual data and waste a lot of storage space.

The preferred option to help solve the XML performance problem is a technique called binary XML, which uses a new format that compresses XML data. Sun has launched a binary XML technology FAST INFOSET Project, which is responsible for the "Global Network Alliance" "Global Network Alliance", which is responsible for XML, has set up a special working group to consider binary XML standards.

From the surface, it is reasonable way to compress the XML document using different file formats. It seems to address the problem of low performance, but this concept makes many people worry that this will lead to incompatible XML versions. XML Joint Inventor, SUN Software Group official Breta said that if I am a world dictator, I will block the binary XML, I am convinced that people who support it will also find other solutions. These people think they are correct, think they are not stupid, this may be right. We expect them to work well with standard agencies to provide free open source software.

Fast Infoset Project recommends that an XML document should be compressed into a binary format in order to improve the file transfer speed on the Internet. Sun has chosen a compression format that has been subjected to the telecommunications industry. SUN engineers participating in Fast Infoset Project believe that binary coding is required because it can greatly improve performance. In the initial test, they found that the performance of the application of binary XML has increased by 2, 3 times.

The goal of Fast Infoset Project is to stimulate the interest of developers and eventually create a standard binary format. The consumer electronics manufacturers represented by Canon also support binary XML. They believe that if there is no binary XML technology, large files such as downloading images are required to download images on devices such as mobile phones.

The main concerns of binary XML are compatibility. A number of different binary formats for specific purposes may occur on the market. Bray is skeptical about the concept of non-text format XML. He said that the fact has proven that XML in text format has many benefits. If this simple way is not used, it may cause compatibility issues. The compatibility experience gained through XML is really great, why do you want to lose compatibility insurance?

Bray pointed out that in addition to binary XML, there are other methods to accelerate the transmission of XML documents. He said that the progress of equipment handling capacity and network has greatly improved XML transmission speed, although XML's performance is still very interested in the performance of battery capacity restrictions on battery capacity.

IBM Information Management Group General Manager Janet said that an alternative to binary XML is to grow through the speed of XML traffic through a fast speed. She said, at 5, 6 years ago, people think that the Internet is too slow, not suitable for business activities, but these issues are ultimately resolved. She pointed out that I think the growing XML traffic is not a problem, we can solve this problem. Market Research Manufacturers Zapthink also expressed concerns about binary XML, the most prominent is the possibility of dedicated implementation. The company's analysts pointed out that XML messages are related to several different soft, hardware parts, such as security systems, all of which require two binary XML standards in any format. The company's analyst dragon said that binary XML may be limited to a few applications, such as the need for the highest performance.

Jeff supports binary XML, but he warned that it needs to be standardized. He said that the number of transactions containing XML will continue to grow rapidly, so we can't fall behind this problem. But if you don't realize the standardization of binary XML, I will not support it.
