The third conference room of Chongguang Communication is located on the fifth floor, with a usable area of nearly 200 square meters, equipped with a large-screen projector, and ten large whiteboards are erected for erase and writing.

Hu Yiting had already pulled out five whiteboards at this time, writing densely and speaking with a dry mouth.

"Does anyone have any questions?" Hu Yiting asked for the third time, and this time everyone finally looked at each other, and no one had any doubts.

In the three-day technical seminar, Hu Yiting analyzed the core technology and technology evolution route of the next-generation STP signaling machine clearly, and the 32 engineers who participated in the meeting no longer had any doubts, and they also admired Hu Yiting.

At present, in the STP signaling machine market, the C1 bureau located in the eight major cities, that is, the equipment used by the regional central bureau is occupied by Alcatel, Ericsson, Lucent, Bell telephone without exception, the C2 bureau provincial central bureau and the C3 regional central bureau are the same, C4 city center bureau has a small part of domestic equipment, the performance is average, C5 county and township bureau is the main battlefield of domestic signaling equipment.

Hu Yiting knew that Huachuang also began to enter STP signaling equipment in 96 years, because he made a lot of money on the program-controlled machine, and after accumulating funds, Qin Zhenfei was ambitious to expand Huachuang's territory, and naturally he would not let go of STP signaling equipment, but Huachuang's early products were technically very ordinary, not to mention that they were not better than foreign countries, but they had no advantage over the things made by Telecom's own subordinate research institutes。

Until 1997, Hua Chuang's CC08 program-controlled telephone exchange won the second prize of the National Science and Technology Progress Award, the main R & D personnel in the Great Hall of the People by the party and state leaders to meet, Qin Zhenfei found an opportunity, and finally Hua Chuang's STP equipment project to the beginning of the test, began to be in Hua Chuang's most familiar C5 bureau one by one sales, and gradually opened up sales, but the sale has not been good, until the mobile separation from telecommunications, the need to purchase a large number of signaling network equipment, Hua Chuang found a breakthrough, and then after more than ten years of continuous technology accumulation and improvement, it finally got better and better to the high-end, won half of the domestic STP equipment。

Hu Yiting can't wait so long, his vision is very high, and his goal is to PK the products of world-class manufacturers, rather than counting on selling more than ten or twenty units a year in the C4C5 bureau like Qin Zhenfei did at the beginning, and gradually improve the technology to open up the market.

After China's post and telecommunications system gradually evolved from No. 1 signaling to No. 7 signaling, it was faced with the need to gradually establish a signaling network in addition to the telephone network.

The traditional No. 1 signaling, as a path-attached signaling, transmits the signaling along with the channel, which not only has a slow transmission speed, but also has a small amount of information, which is not conducive to the development of various new services in the telecommunications service industry.

Later, the No. 2 signaling was gradually developed internationally, and the No. 2 signaling used dial-up pulse to send signaling, but it was not put into use because it had no special advantages over the No. 1 signaling and required additional equipment.

Then CCITT, that is, the International Telegraph and Telephone Advisory Committee, came up with the No. 3 signaling, the No. 4 signaling and the No. 5 signaling, the No. 3 signaling is a single-audio in-band signaling, the No. 4 signaling is a dual-audio in-band signaling, and the No. 5 signaling uses the combination of two frequencies in the six voice frequencies to transmit various signaling, that is, the in-band dual-tone multi-frequency signaling, but it is not well promoted in the world, and is only applied in the capitals or commercial centers of a few developed countries.

Later, the revolutionary product of program-controlled telephone exchange was born, and the number of telephone users around the world began to surge, in order to apply the development of digital program-controlled exchange, the International Telegraph and Telephone Advisory Committee (CCITT) Finally, in 1968, the No. 6 signaling was proposed, which is a common road signaling, the message length is fixed at 28 bits, and some large cities in western developed countries have adopted this kind of signaling, but China is still on the move, until 1980, CCITT evolved the No. 6 signaling to the No. 7 signaling system, which is a mature high-quality signaling system, and China decided to make a leap forward, from the No. 1 signaling directly to the No. 7 signaling transition.

It can be said that our country's choice is very rational, and there is no blind follow-up, otherwise the equipment replacement from generation to generation will cost countless wronged silver, and the direct transition from the No. 1 signaling to the No. 7 signaling gives us a late-mover advantage and a lot of detours, but in fact, it is also a helpless move, after all, the country does not have so much money to follow the trend.

No. 7 signaling requires telecom operators to set up a special signaling network in addition to the telephone network for the transmission of all signaling, so that it can not interfere with the transmission of large amounts of information quickly, safely and reliably. Once a problem occurs in the signaling network, such as the failure of a signaling equipment will cause the entire link to be paralyzed, thousands of users will not be able to make normal calls and access the Internet.

Fast, safe, reliable, large data volume, no interference, the five advantages determine that it is wise for China to jump from the first signaling to the seventh signaling, and later it turns out that the seventh signaling may be used by the earth's human beings until the sky is old, and it is possible to use it for another hundred years.

In the field of telecommunications equipment, high-end STP equipment bears the heavy responsibility of the command, so the technical difficulty is large, and the reliability requirements of almost never shutting down are almost perverted, so the value of millions of dollars, the company that can make achievements in this field is enough to be proud of its products, which is equivalent to having a beautiful business card in the international telecommunications industry.

Hu Yiting's choice of technical solutions comes from the design of Huachuang 02, but the main idea and technical evolution choose Cisco's products, from his heart, he still does not want to block the way of Huachuang, and hopes to form a healthy competition with Huachuang in the future.

In the technical scheme that Hu Yiting came up with, the core is MPLS technology, which is a multi-protocol label switching standard protocol proposed by Cisco in 1997 and formulated by the IETF Internet Engineering Task Force, which uses Layer 2.5 switching technology to combine Layer 3 technology (such as IP routing, etc.) with Layer 2 technology (such as ATM, Frame relay, etc.), so that it can provide both point-to-point transmission and multi-point transmission on the same network, which can not only provide Internet services, but also provide low-latency and low-congestion real-time switching services with high security and high quality assurance.

In this way, Chongguang can attack Cisco, the boss of network router products, while entering STP equipment, Hu Yiting trembled with excitement at the thought of coming up with an idea from Cisco a year in advance, making a mature system solution, and even making a device prototype and software platform.

It is important to know that the technical evolution route of Cisco's multi-functional products is also clear and clear, that is, to integrate the signaling exchange of traditional phone services and the integrated service digital network to achieve unified management of the integrated platform solution, combined with equipment for sales, and provide turnkey projects for telecom operators.

After listening to Hu Yiting's three-day technical report day and night, and after conducting detailed technical discussions and explanations of the difficulties, the 32 core engineers of Chongguang Communication who participated in the meeting were very excited, forgot their fatigue under the stimulation of black coffee, and began to collectively discuss how to allocate the research and development tasks of various technologies.

Hu Yiting asked Zhu Jun to make a co-ordination and gather the current key forces of Chongguang Communications, including the transfer of backbone engineers from the Puhai Branch and the Shenzhen Branch, to concentrate on the Hushan base for closed development.

"Work hard for 60 days and come up with a product prototype!" Hu Yiting said proudly.
