Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Based on the entire information network architecture of the State Grid Corporation in the embodiment of the present invention, the business data packets will automatically select the best route according to different data flow destinations, so that the business data can be shunted as soon as possible, and network congestion can be fundamentally avoided; at the same time, the national The backbone network of the power grid company flexibly adjusts the network topology in all directions as needed, laying a good architectural foundation for future business expansion, structural adjustment, and long-term evolution capabilities of the backbone network.

Before realizing the embodiment of the present invention, it is first necessary to carry out research on the current situation of the company's information network architecture, analyze the differences between the current situation of the network architecture and the company's informatization development and business development needs, combine the analysis of the company's future informatization development business flow, carry out business classification, and Research and analyze the data flow direction and bandwidth requirements of various services, and then investigate the nodes of the underlying link according to the company's transmission bearer network, and carry out the adjustment of the information network architecture after fully considering the above aspects. Specifically, the following will be described by way of example in conjunction with the network architecture and data flow schematic diagram shown in Figure 1. Each circle in Figure 1 represents a network node. Of course, there may be other network nodes between these network nodes:

First of all, according to the full research on the business development direction and the underlying transmission link resources, determine the core nodes and backbone nodes of the entire network. In the network architecture shown in Figure 1, Beijing Xidan Headquarters, Beijing Disaster Recovery Center, Xi'an Disaster Recovery Center, and Shanghai Disaster Recovery Center are the core nodes, the first convergence point of provincial companies in Central China, the second convergence point of provincial companies in Central China, The first node and the second node are backbone nodes, wherein the first convergence point and the second convergence point can be deployed in different cities in the same province, the first convergence point and the first node can be deployed together, the second convergence point and The second nodes can be deployed together.

Then, the function (bearer service) of each core node is defined. According to the company's future business development plan, it is assumed here that disaster recovery replication services will eventually flow to the three disaster recovery centers, video services will eventually flow to the headquarters, and comprehensive office services will eventually flow to the headquarters data center (not shown in the figure).

Finally, plan the interconnection mode and link bandwidth between core nodes and backbone nodes. It is initially designed as a high-bandwidth, triangular ring structure redundant architecture between core nodes. Fully consider the multiple business applications and multi-directionality of the core nodes, design the high bandwidth between core nodes and the reliable network architecture of the double triangle ring, and adopt the word-shaped double uplink structure to ensure the reliability of the backbone nodes.

Referring to FIG. 2 , it is a schematic flowchart of a method for controlling the flow of business data provided by Embodiment 1 of the present invention. The steps for implementing the method include:

Step 201: Determine the final destination of the first business data of the first provincial company in the network architecture, the network architecture includes each provincial company node in each area, at least one disaster recovery center node and the headquarters node, the final The destination is the first disaster recovery center node or the headquarters node corresponding to the first provincial company node.

Step 202: Determine multiple paths of the first service data from the first provincial company node to the final destination.

Step 203: Select a first path with the least network bandwidth pressure from the determined multiple paths, and control the first service data to flow to the final destination through the first path.

In order to understand Embodiment 1 of the present invention more conveniently, below in conjunction with Fig. 1, introduce Embodiment 1 of the present invention by way of example, assume Fig. 1 that the provincial company in the central China region is Henan Provincial Company (i.e. the first provincial company):

In Figure 1, it is assumed that the Shanghai Disaster Recovery Center is responsible for receiving business data (such as video business data, or disaster recovery business data or other business data) uploaded by provincial companies in Central China and East China. Beijing Disaster Recovery Center, Xi'an Disaster Recovery Center and Beijing Xidan Headquarters also has the business data of provincial companies in certain preset areas that it is responsible for receiving. When the provincial company in the central China region in the figure is a Henan provincial company in the central China region, the final flow destination of the business data of the Henan provincial company (ie, the destination address of the data flow) is determined according to the type of business data and the preset flow direction. After the final destination of the company's business data in Henan Province is determined, the various business data of the company in Henan Province will be uploaded to the determined final destination through the company's node in Henan Province (that is, the first gathering point of the company in Henan Province). When it is the Shanghai disaster recovery center, since there may be multiple network paths for data transmission between the first aggregation point of the Henan provincial company and the Shanghai disaster recovery center, it is necessary to use the first aggregation point of the Henan provincial company as the source to calculate from Henan The path from the first convergence point of the provincial company to the Shanghai disaster recovery center node is used to determine the network paths between the two. In order to reduce the bandwidth pressure of the entire network, try to select a path with the least network bandwidth pressure from these network paths. And make the business data of the company in Henan flow from the first gathering point of the company in Henan to the disaster recovery center in Shanghai through the selected path.

Referring to FIG. 3 , it is a schematic flowchart of a method for controlling the flow of business data provided by Embodiment 2 of the present invention. The steps for implementing the method include:

Step 301: Determine the final destination of the first business data of the first provincial company in the network architecture. The network architecture includes each provincial company node, at least one disaster recovery center node and headquarters node in each area. The final The destination is the first disaster recovery center node or the headquarters node corresponding to the first provincial company node.

Step 302: Determine whether the node of the first provincial company is faulty, if yes, execute step 305, if not, execute step 303.

Step 303: If the first provincial company node is not faulty, determine multiple paths for the first service data from the first provincial company node to the final destination.

Step 304: Select a first path with the least network bandwidth pressure from the determined multiple paths, and control the flow of the first service data to the final destination through the first path, and the process ends.

For a more convenient understanding of Embodiment 2 of the present invention, Embodiment 2 of the present invention is still introduced below in conjunction with FIG. 1 by way of example. Here, it is still assumed that the provincial company in the central China region of FIG. 1 is a Henan Provincial Company (i.e. the first provincial company) :

When it is determined that the final destination of the company's business data in Henan Province is the Shanghai Disaster Recovery Center, various business data of the company in Henan Province will be uploaded to the Shanghai Disaster Recovery Center through the company's node in Henan Province (that is, the first gathering point of the company in Henan Province). But before that, it is necessary to determine whether the first aggregation point of the Henan Provincial Company is working normally, that is, whether data transmission can be performed normally. A first path is selected from the plurality of network paths to transmit service data.

In step 304, a first path with the least network bandwidth pressure is selected from multiple paths in the following manner, also in conjunction with Figure 1 and assuming that the first provincial company is a Henan provincial company, and for the Henan provincial company’s first Multiple paths from the convergence point to the Shanghai disaster recovery center node, calculate the COST value of each path (the COST value refers to the cost of reaching the destination address indicated by a certain route, which can be set manually or automatically, in the embodiment of the present invention By manually setting), compare the COST values corresponding to each path, select the path corresponding to the minimum COST value as the optimal path, and finally transmit the business data through the optimal path. However, when the selected optimal path When the optimal path fails or is abnormal, it will automatically compare again and select the suboptimal path for data transmission. Based on the above content, the function of selecting the first path in step 304 is specifically implemented in the following manner:

Determine the COST values corresponding to the multiple paths respectively;

Selecting a path corresponding to the minimum COST value from the plurality of paths;

If the selected path is normal, using the selected path as the first path;

If the selected path fails, select a path corresponding to the minimum COST value from other normal paths as the first path.

Step 305: In the embodiment of the present invention, the network architecture further includes affiliated data aggregation nodes corresponding to each provincial company node. If the first provincial company node fails, multiple paths for the first service data from the affiliated data convergence node corresponding to the first provincial company node to the final destination are determined.

Step 306: Select a second path with the least network bandwidth pressure from the determined multiple paths, and control the flow of the first service data to the final destination through the second path, and the process ends.

In Fig. 1, if the first provincial company is a Henan provincial company, the affiliated data convergence node corresponding to the Henan provincial company node (i.e. the first gathering point of the Henan provincial company) is the second gathering point of the Henan provincial company, when the Henan provincial company When the first convergence point fails to transmit data normally, the business data of the Henan provincial company, such as video business data, will converge to the second convergence point of the Henan provincial company through the first node and the second node at the bottom of Figure 1. It can be seen that the first node and the second node at the bottom of Figure 1, the first convergence point of the Henan Provincial Company, and the second convergence point of the Henan Provincial Company form a double-uplink structure, which ensures the reliable operation of the backbone nodes. sex.

When the first convergence point of the Henan Provincial Company fails and the final destination of the Henan Provincial Company's business data is determined, the various business data of the Henan Provincial Company will pass through the affiliated data convergence node corresponding to the Henan Provincial Company node (that is, the second convergence point) to the determined final destination. When the final destination is the Shanghai disaster recovery center, there may be multiple network paths for data transmission between the second convergence point of the Henan Provincial Company and the Shanghai disaster recovery center. Therefore, it is necessary to calculate the path from the second aggregation point of the Henan Provincial Company to the Shanghai disaster recovery center node using the second aggregation point of the Henan Provincial Company as the source to determine the network paths between the two. In order to reduce the bandwidth pressure of the entire network, Try to select a path with the least network bandwidth pressure from these network paths, and make the business data of Henan Provincial Company flow from the selected path of the second convergence point of Henan Provincial Company to the Shanghai Disaster Recovery Center.

In step 306, a second path with the least network bandwidth pressure is selected from multiple paths in the following manner, also in conjunction with Figure 1 and assuming that the first provincial company is a Henan provincial company, and the second path from the Henan provincial company Multiple paths from the convergence point to the Shanghai disaster recovery center node, calculate the COST value of each path (the COST value refers to the cost of reaching the destination address indicated by a certain route, which can be set manually or automatically, in the embodiment of the present invention By manually setting), compare the COST values corresponding to each path, select the path corresponding to the minimum COST value as the optimal path, and finally transmit the business data through the optimal path. However, when the selected optimal path When the optimal path fails or is abnormal, it will automatically compare again and select the suboptimal path for data transmission. Based on the above content, the function of selecting the second path in step 306 is specifically implemented in the following manner:

Determine the COST values corresponding to the multiple paths respectively;

Selecting a path corresponding to the minimum COST value from the plurality of paths;

If the selected path is normal, using the selected path as a second path;

If the selected path fails, select a path corresponding to the minimum COST value from other normal paths as the second path.

Furthermore, in order to prevent the failure of the disaster recovery center from receiving and storing business data normally, multiple disaster recovery centers with different priorities can be configured for each provincial company node. The flow direction includes Shanghai disaster recovery center and Xi'an disaster recovery center, and the priority of Shanghai disaster recovery center is higher than that of Xi'an disaster recovery center. It is the Shanghai Disaster Recovery Center; otherwise, the current final destination of the first gathering point of companies in Henan Province is the Xi'an Disaster Recovery Center. Therefore, in Embodiment 1 and Embodiment 2 of the present invention, since the disaster recovery center node corresponding to the first provincial company node includes a plurality of disaster recovery center nodes with different priorities; therefore in step 201 and step 301, the The first disaster recovery center node corresponding to the first provincial company node is the disaster recovery center node that works normally and has the highest priority among the plurality of disaster recovery center nodes with different priorities.

The method for controlling the flow of business data provided by the embodiment of the present invention is based on the improved network architecture, by determining the final destination of the first business data of the first provincial company in the network architecture, and then determining the origin of the first business data from the multiple paths from the node of the first provincial company to the final destination, and select a first path with the least network bandwidth pressure from the determined multiple paths, so as to control the flow of the first business data through the first path The final flow goes to ground. It can be seen that business data packets can automatically select the best route from multiple paths according to different data flows to the destination, so that business data can be shunted as early as possible, and network congestion can be fundamentally avoided.

In addition, the network of the present invention has high robustness, eliminates the potential failure of a single device and a single link, and meets the disaster recovery requirements that when a node of the data communication backbone network fails, the services of other nodes other than this node are not affected.

In addition, the network structure of the present invention is clearly layered, and the function positioning of core layer nodes and backbone layer nodes is clear. In terms of business support capabilities, the interconnection bandwidth can meet the company's information and communication business needs in the next five years. In terms of equipment performance selection, the performance of the selected equipment meets the business and bandwidth expansion capacity requirements of the power grid company in the next 10 years, and the difference in equipment performance between core nodes and backbone nodes is considered. The overall functional structure and business flow of the network are clear and reasonable, and it is easy to implement network deployment and strategy planning. The network topology should facilitate the management and maintenance of the operation of the data communication backbone network.
