Yang Jie said with a smile: "President Chen, in addition, we also welcome Ziguang University to come to Tanzhou City to open a branch, I know that your school in Pengcheng High-tech Zone joint venture research institute has also achieved fruitful results over the years, now Tanzhou City has become a gathering area of many high-tech clusters, there is a great demand for high-level R&D personnel, if Ziguang University can open a branch there as a local talent training base and high-tech company incubator would be great." ”

Chen Deming glanced at Yang Jie and said with a smile: "Since it was Yang Dong's kind invitation, I will have a meeting to discuss it after I go back." ”

He knows that Tanzhou City has formed a financial industry chain with dozens of venture capital companies, fund companies, science and technology small loan companies, science and technology guarantee companies, and financial leasing companies as the core, especially Huaxing Venture Capital Company, founded by Guanghua Bank, is the largest professional investment platform, with tens of billions of funds invested every year, and a large number of listed technology companies have been incubated.

Moreover, the Tanzhou municipal government has also created a large investment platform, and other investment platforms have invested tens of billions of dollars in these emerging high-tech companies every year, and these blowout high-tech companies have also brought hundreds of billions of industrial value to the Central Plains Province.

Now the Central Plains Province has become the region with the highest density of high-tech companies, and there are faint signs of catching up with the United States' Silicon Valley.

Central Plains Province has become a major province of science and technology, that is, in the past five or six years, the rapid changes make people feel a little dizzying.

And all this is inseparable from Huaxing Group and Hexi Science and Technology Corridor.

At present, several cities near Tanzhou City in Central Plains Province have copied the model of the Hexi Science and Technology Corridor, and also established a high-tech zone, but it is not a simple copy, but there is a bias and difference, basically creating a high-tech industrial circle, providing various supports for several pillar industries in the Central Plains Province.

The current Tanzhou City can really be said to be rich, and the scale of the city is constantly expanding, and the population is about to exceed 10 million, Chen Deming is naturally willing to go to Tanzhou City to open a branch.

Zhou Hongzhou looked at Yang Jie in front of him, and he was also quite emotional in his heart, who would have thought that this young man would have founded a world-class international enterprise in less than ten years, and completely changed the pattern of many domestic industries.

Now the Chinese Academy of Sciences has set up a research and development institution in Tanzhou City to serve the companies and enterprises gathered there, and it has also benefited a lot.

"By the way, the southbound interface protocol standard meeting held in Yanjing will be held tomorrow, this agreement is led by Huaxing Group Company, I heard that this new network architecture is your idea, you have to say more dry goods at the meeting!"

Zhou Hongzhou said to Yang Jie with a smile.

"Forget it, I'm just providing an idea, and the specific things are done by these technical experts in the company, so let them say more. ”

Yang Jie waved his hand and said.

The southbound interface protocol describes the interaction information between the controller and the switch, this set of technology originated from the Ethane research project on network security and management at Stanford University in the previous life, and the first official version was released at the end of 09 and went through the evolution process of 1.1, 1.2, 1.3 and 1.4 versions, and the most used and supported versions in the previous life were 1.0 and 1.3.

Before Yang Jie's rebirth, Huatai Company also carried out a lot of application exploration of this new network architecture, and there are also a large number of patent standards in this network architecture standard organization.

After Yang Jie's rebirth, he naturally let the company's technical experts study and explore the SDN network architecture, and released the official version of the southbound interface protocol the year before last, and also formed a southbound interface protocol standards organization association with many universities and enterprises in China, which is updated and maintained by this association, and the Chinese Academy of Sciences is also one of the members of this organization association.

SDN's new network architecture is an architecture that separates control and forwarding, separating the control logic from the network equipment and handing it over to the central controller for centralized and unified control to achieve flexible deployment of network services, and the southbound interface protocol serves as the standard interface for communication between the controller and the switch.

The proposal of this southbound interface protocol has made it easier to study the new network system, so the release of this protocol version has attracted the attention of the academic community and many communication technology companies, and many universities and enterprises have joined this association.

The previous network technology has always evolved in a passive way, and the improvement of the network is mainly focused on the improvement of the performance of these network devices themselves, and each time in order to improve the network, the equipment must be upgraded, and the deployment and change technology of the network is becoming more and more complex.

The virtualization of network equipment optimizes the network architecture within a certain range and scale, simplifies the network design, and supports the large-scale Layer 2 diffusion computing of virtual machines under virtualization conditions by eliminating loop factors.

The emergence of this concept and technology of defining the network through software has given the network a greater degree of flexibility.

This architecture separates the control plane and opens it to users, allowing high-end users to program, quickly adjust according to their own needs, and respond quickly to changes in applications and traffic, without relying entirely on long-term software and hardware upgrades from equipment vendors.

Yang Jie's initial purpose of letting the company develop this is also to eliminate the difficulty of centralized management of various equipment in the internal factory of Huaxing Group.

At the beginning, the source of equipment purchased by Huaxing Group was very mixed, because of different hardware and private software from suppliers, the network itself was relatively closed, and it could only operate with computing equipment through standard interoperability protocols.

The functions and configurations of different devices vary greatly, which also makes network changes complex and workload-intensive, and because of heterogeneous devices, management compatibility is very poor, and the modification or evolution of network functions will involve the upgrade and update of the entire network.

To this end, Huaxing Group has developed such a set of standard network hardware and software supporting southbound interface protocols, and has also found software for these equipment manufacturers to make their devices support this protocol.

This new network architecture hardware device is not a traditional switching mode, but a stream table for data forwarding and processing, which is very similar to the current switch use of TCAM to classify and control data flows, each network in the network is controlled by the rules in the flow table, can achieve extremely fine granularity.

The southbound interface protocol defines a common data plane description language, and the southbound interface agent software on the device accepts control forwarding instructions to the device by establishing a secure encrypted communication tunnel with the southbound interface controller. All flow table instructions are defined as standard specifications and are reliably delivered through the cryptographic protocol between the controller and the proxy.

Huaxing Group has also developed TCAM meter equipment and network chips, but now this set of equipment is not perfect, used to replace other networks also need many domestic R & D institutions to improve this set of standards, at this stage to replace the existing mobile communication network There is still a long way to go.

This new network architecture redefines the way network equipment is provisioned, but this definition makes the network not a smooth upgrade and evolution, but a disruptive update, and the existing network cannot be upgraded through southbound interfaces, but needs to be completely replaced.

However, several domestic communication operators such as Huaxia Telecom, Huaxia Mobile, and Huaxia Unicom also saw the huge commercial benefits of this southbound interface protocol standard, and immediately joined this standard organization, and required domestic and foreign equipment to support this protocol standard.

Because the source of equipment from these companies was very complex, the cost of upgrading the network was very large, and a large number of devices in the previous network were scattered and independent, and the management and compatibility were very poor.

Now, with the southbound interface protocol standard, the design, deployment, O&M, and management of the network can be completed at one control point, and the differences in the underlying network are eliminated due to the decoupling architecture.

Now, these telecom operators only need to design and program the software according to their business needs, and then load it at the network control point, so that the whole network can quickly upgrade new network functions, without having to operate each NE node independently, which is the most important thing for these telecom operators.
