China Telecom 1 billion 300 million yuan net built close said CN2 very high price

July 18th, China Telecom set up test group design and equipment group closed, Zhang Quanxin plans to build a IP backbone network. August, in the name of the integration of Chinanet network to start the initial test equipment.

In October 19th this year, the China Telecom internal inspection briefing as its epic project CN2 secret conference once heard this news: in some high-end routers provider for CN2, there are two suppliers of equipment appeared basic problems unforgivable, the maintenance department of China Telecom to refuse to accept, and CN2 also shelved for more than a month. The industry have speculated that the grand masterpiece of China Telecom will be shelved?

Question

However, the day before came further news, China Telecom have been responsible for the operation and maintenance of CN2 in some provinces and cities in the acceptance of the contract signed. The industry is also suspected of more geological origin: China Telecom in order to worry about the launch of a new business and swallow a quality network?

"The main project communications industry newspaper" the reporter then call the China Telecom CN2 is responsible for one of Xu Jianfeng, although he is not much, but with certainty to reporters that CN2 does not have any problems, all questioned process will be in the second half of this year the white in the world, 1 billion 300 million yuan built a CN2 in the international are commendable network, the cost is very high.

A few days ago, insiders told reporters that the acceptance of the CN2 project is signed in the provinces, which in the first round of the headquarters of the telecommunications representative of the acceptance of the only four provinces. Jiangsu, Fujian and Hunan are built by CISCO, Guangdong is built by Juniper, two in the high-end router competitors first received diamond cuts diamond China Telecom "Pass" license.

Initially, according to the region divided into six packages CN2 by four manufacturers to carve: Central China swept by CISCO (second pack and sixth pack), the Southern China region was swept Juniper (first and third bales), northeast and Northern Shanghai are responsible by Bell Al Carter and HUAWEI. The remaining two vendors are responsible for the package has recently signed a contract for acceptance. Insiders said, CN2 all the acceptance of a week ago has all over.

Address problem is not a problem?

In fact, CN2 can be described as extraordinary significance for China Telecom. Among them, the role of IPv6 unusual, and this has become the most questionable question CN2.

According to the reporter, at the November 28th acceptance meeting, a mainstream router vendors do not even support IPv6 devices, which even the most basic idea seems far from CN2. Xu Jianfeng believes that this is not the problem of suppliers, but suppliers to meet the most junior Telecom CN2 envisaged. After the listing of the China Telecom needs a cost-effective, but also to adapt to the changing network, so CN2 is not just for the future, but on-demand customization. Therefore, although CN2 suppliers are able to provide more high technology level of equipment, but the China Telecom in the procurement has been careful steps, and not all at once with the highest level of technology products.

Xu believes that IPv6 will use 6PE (MPLSIPv6), that is, in the early stages of network construction will be large-scale use of dual stack mode, which is in line with the development trend.

Technical experts pointed out that if the use of double stack, there is the biggest problem of routing table capacity and routing table capacity expansion, and at this point, with the old rookie in the high-end router on have the absolute right to speak in many tests. Xu said that China Telecom for 6PE mode, the current CN2 has been supported, and the results and performance are commendable.

Telecommunications experts told reporters that the backbone network using 6PE is the most economical and most in accordance with international practice, and the biggest breakthrough is in the metropolitan area network and access network."

However, the real investment is large metropolitan area network and access network, China Telecom insiders said, after the completion of the CN2, the follow-up investment has begun, the metropolitan area network optimization has started this year. Metro investment is determined by the provinces, is expected to basically completed 3 years, the transformation of the structure is the 3 year, the function is to enhance the 5 year.

After CN2

Xu Jianfeng does not evade, in the acceptance of the meeting did summarize some of the problems, but there is no big problem affecting business."

It is reported that one of the CN2 on the VPN business, soft exchange load, 3G bearer, Vnet and other applications are not a problem. The IPTV multicast problem is fully meet the design requirements, switching time is very short, packet loss is also very small.

Through a long period of preparation, more than 5 months of testing and optimization, CN2 designers believe that although there are some problems, but through the design adjustment can be overcome. Xu Jianfeng said, such as large-scale CN2 network, in the next 2 years, or to continue to optimize, in order to enrich its performance, the current telecommunications has been proposed in the interior of nearly more than and 50 optimization and improvement recommendations."

It is understood that the China Telecom has now soft switch full swing, DC1 (1 level exchange) 31 provincial capital city, Zhejiang, Guangdong, the level of Shaanxi, Ningxia, Guangdong and other regions are in full swing, 31 of the capital city of Zhejiang and Guangdong have been preliminary acceptance, has been loaded into the CN2.

However, there are China Telecom insiders told reporters that important work is still behind, the management of the network and even publicity will be decided to play a full role in the CN2 more important thing. Twelve thousand and fifty-five
