[0058] A call data recording method provided by the present application will be described in detail below with reference to the accompanying drawings.

[0059] The term "and / or" in this paper is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone.

[0060] The terms "first", "second", and the like in the description of the present application and in the claims of the present application are used to distinguish different objects, or to distinguish different treatments of the same object, and are not used to describe a specific order of the objects.

[0061] In addition, the terms "comprise" and "have" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0062] It should be noted that in the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of "exemplary" or "for example" is intended to present relevant concepts in a concrete manner.

[0063] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, "first", "second" and the like are used to distinguish the same or similar items with basically the same function and role, and those skilled in the art can understand that "first", "second" and the like are not limited in number and execution order.

[0064] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0065] "East number west calculation", namely the east number west calculation project, refers to the construction of a new type of computing power network system integrating data centers, cloud computing and big data, which orderly guides the east computing power demand to the west, optimizes the construction layout of data centers, and promotes the coordinated development of the east and west, aiming to solve the problem of uneven distribution of computing power resources in the east and west of China. Specifically, "east number" refers to the huge amount of data in the eastern region, and "west calculation" refers to the relatively surplus computing power resources in the western region. Although the eastern region has a large number of data centers, the digital economy develops rapidly and has a large demand for computing power, resulting in a shortage of computing power resources; while the western region has abundant energy and land resources, and has the potential to build data centers.

[0066] With the implementation of the East Numerical West Algorithm project and the continuous development of computing power network, computing power resources have become the key to future industrial development. Users in the eastern region need to send a large amount of data to the computing power hub node in the western region, and the data will be sent from the eastern region to the western region through the backbone network. How to fully utilize the limited bandwidth resources of the backbone network, and efficiently transmit the massive data provided by the eastern computing power business to the western region under the premise of ensuring smooth operation of the network has become a problem to be solved.

[0067] The prior art only considers the allocation, scheduling and computing power routing of computing power resources, and uses a transmission link with small load to distribute data to a relatively idle computing power hub node, without considering the impact of massive data transmission on the bandwidth of the operator backbone network. For example, data is sent to other devices within the same communication network that can communicate with each other, or data is sent to the western region through a non-shortest path (minimum routing hop count) through different paths (routes), without considering the problem of network utilization busy and idle, and the imbalance of uplink and downlink utilization on the metropolitan area network, affecting data transmission efficiency.

[0068] To solve the above technical problems, the present application provides a data transmission method applied to a cache node connected with a core router (CR) device, the idea of which is to receive target service data to be processed in a first region; the target service data is data that needs to be transmitted to a computing power node in a second region for processing; store the target service data; and send the target service data if a preset transmission condition is met. As can be seen, the present application introduces a cache node for temporarily storing target service data that needs to be transmitted across regions, and determines whether to send the target service data according to the preset transmission condition. In this way, the target service data can be temporarily stored in an unfavorable data transmission condition, and the target service data can be sent in a transmission condition, fully considering the data transmission demand in different situations, and the efficiency of data transmission can be improved.

[0069] The data transmission method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0070] Figure 1 The network architecture of the urban broadband core network is shown in FIG. 1, which includes: Figure 1

[0071] The backbone network refers to a high-speed network trunk line connecting multiple cities or regions. In the East Numerical West Algorithm project, the backbone network plays a key role, as it is responsible for connecting data-intensive areas in the east and computing power resources in the west, ensuring efficient and fast data transmission.

[0072] ​Core router (CR), also known as backbone router, is a very important device in network architecture, which is responsible for processing and forwarding a large number of data packets to ensure smooth flow of information.

[0073] Content Delivery Network (CDN) mainly provides acceleration services for video content, which can cache content on servers closer to users, reducing the distance and time of data transmission, thereby speeding up the loading speed of content.

[0074] Broadband Network Gateway (BNG) is responsible for the access management of broadband users. BNG includes User Plane (UP) device and Control Plane (CP) device. Among them, CP device is mainly responsible for user authentication, authorization, address allocation and other management functions, while UP device is mainly responsible for processing user data traffic forwarding, including traffic reception, forwarding and state maintenance tasks.

[0075] Aggregation switch is located between access layer switch and core layer switch. It is mainly responsible for aggregating access layer traffic, transmitting, forwarding and switching data packets, and performing local routing, filtering, traffic balancing, QoS priority management and security mechanisms according to traffic requirements.

[0076] Optical Line Terminal (OLT) is responsible for connecting with core network and providing optical signals for user side Optical Network Unit (ONU).

[0077] Optical Network Unit (ONU) is a user side device, usually placed at the user end such as home or office, with multiple Ethernet ports that can support multiple user devices to access simultaneously.

[0078] Among them, ONU is connected with OLT or aggregation switch, OLT and aggregation switch are connected with UP, UP is connected with CR, CR is connected with backbone network, CDN is connected with CR, and CP is connected with UP.

[0079] For urban broadband core network, terminal users access operator ONU device through optical modem, aggregate and access to OLT device in the cell, and then connect to UP device in the region (according to the number of cells in the region, access through aggregation switch or directly). UP device is connected to CR device, which is connected to backbone network or accesses local city CDN resources through CR device.

[0080] The application introduces a cache node in the above network architecture, which is used to implement the data transmission method provided by the embodiments of the application. In some embodiments, the cache node includes a memory for storing a large amount of computing power business data involved in the east-data-west-computing scenario, and the cache node further includes a processor for preprocessing the computing power business data or determining whether to send the computing power business data by judging whether a preset transmission condition is met.

[0081] Figure 2 A network architecture diagram is provided for the embodiments of the application. As shown in Figure 2 , the cache node is connected with a core router CR.

[0082] It should be noted that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0083] The data transmission method provided by the embodiments of the application will be described in detail below.

[0084] Figure 3 A flowchart of a data transmission method is provided for the embodiments of the application, which is applied to a cache node as shown in Figure 2 , as shown in Figure 3 , the method comprises:

[0085] S101: receiving target business data to be processed in a first region.

[0086] Among them, the target business data is data that needs to be transmitted to a computing power node in a second region for processing.

[0087] Illustratively, the first region is a region with relatively high demand for computing power due to rapid economic development and large amount of data generation; the second region is a region with rich energy resources and low operating cost, which is suitable for developing data centers and providing computing power services.

[0088] In some embodiments, the target business can be a computing power business, for example, a business that consumes a large amount of computing power resources and has no specific requirements for latency.

[0089] S102: storing the target business data.

[0090] Illustratively, the target business data can be stored in the memory space of the cache node; or the cache node includes a memory, and the target business data can be stored in the memory of the cache node.

[0091] S103: transmitting the target service data when the preset transmission condition is met.

[0092] In some embodiments, the preset transmission condition is determined based on a requirement on a network state parameter, for example, a bandwidth utilization ratio.

[0093] It can be understood that setting the preset transmission condition can ensure that the network used for transmitting data is in an ideal state when the target service data is transmitted, thereby ensuring that the process of transmitting the target service data is stable and unblocked, and realizing efficient information flow.

[0094] In some embodiments, the data transmission method further includes preprocessing the target service data. Based on this, the above step S103 can also be implemented as: transmitting the preprocessed target service data.

[0095] For example, the principal component analysis (PCA) technology can be used to reduce the dimension of high-dimensional data, thereby reducing the computational complexity and extracting the most important features. Or the data is grouped by a clustering algorithm, and similar data points are classified together to facilitate further analysis and learning tasks.

[0096] In some embodiments, the storage node is also used to store data in a content delivery network (CDN) device. For example, video data and the like.

[0097] In some embodiments, the storage node can be established based on the original CDN node.

[0098] It can be understood that the cache node provided by the embodiments of the present application can be used to store data in the CDN, or the cache node can be established based on the original CDN node, realizing storage device sharing, maximizing the use of network bandwidth (uplink and downlink bandwidth), and saving the construction cost of the operator network.

[0099] In summary, the data transmission method provided by the embodiments of the present application has at least the following beneficial effects: by introducing the cache node, the target service data that needs to be transmitted across regions is temporarily stored, and whether to transmit the target service data is determined according to the preset transmission condition. In this way, the target service data can be temporarily stored in the case that the data transmission is not favorable, and the target service data is transmitted in the case that the transmission condition is met. The data transmission demand in different situations is fully considered, and the efficiency of data transmission can be improved.

[0100] Next, the implementation of step S103 is described in combination with different application scenarios.

[0101] As a possible implementation, the data transmission method provided by the application is applied to a cache node in a first region, and the cache node in the first region is connected with a CR device in the first region. Step S103 can be specifically implemented as: in the case that a first preset transmission condition is met, sequentially sending the target service data to the computing node in the second region through the CR device in the first region and the backbone network device.

[0102] The first preset transmission condition includes: a bandwidth utilization rate between the CR device in the first region and the backbone network device is less than or equal to a first preset threshold; and a bandwidth utilization rate between the backbone network device and the computing node in the second region is less than or equal to a second preset threshold.

[0103] The first preset threshold and the second preset threshold can be equal or not equal, and the application does not limit this. For example, the first preset threshold is 50%, and the second preset threshold is 50%.

[0104] It can be understood that in the case that the first preset transmission condition is met, the network between the CR device in the first region and the backbone network device, and the network between the backbone network device and the computing node in the second region, are in a relatively idle state and have the ability to transmit a large amount of data. Therefore, sending the target service data in the case that the first preset transmission condition is met can ensure the efficiency and stability of data transmission.

[0105] As another possible implementation, the data transmission method provided by the application is applied to a cache node in a first region, and the cache node in the first region is connected with a CR device in the first region. Step S103 can be specifically implemented as: in the case that a second preset transmission condition is met, sequentially sending the target service data to the cache node in the second region through the CR device in the first region, the backbone network device and the CR device in the second region, so that the cache node in the second region stores the target service data.

[0106] The second preset transmission condition includes: the bandwidth utilization rate between the CR device in the first region and the backbone network device is less than or equal to the first preset threshold, and the bandwidth utilization rate between the backbone network device and the computing node in the second region is greater than the second preset threshold.

[0107] It can be understood that, in the case of meeting the second preset transmission condition, the network between the CR device of the first region and the backbone network device is in a relatively idle state, having the ability to transmit a large amount of data from the first region to the second region, but the network between the backbone network and the computing power node of the second region is in a relatively busy state, not having the ability to transmit a large amount of data, so that the target service data needs to be sent to the cache node of the second region. Such a transmission strategy can ensure the timeliness of data transmission and avoid the risk of transmission delay or data loss caused by network congestion.

[0112] Among them, the second preset threshold value and the third preset threshold value can be equal, or the second preset threshold value and the third preset threshold value can not be equal, which is not limited by the application. For example, the second preset threshold value is 50%, and the third preset threshold value is 50%.

[0113] It can be understood that, in the case of meeting the third preset transmission condition, the network between the CR device of the second region and the backbone network device, and the network between the backbone network device and the computing power node of the second region, are in a relatively idle state, and have the ability to transmit a large amount of data, at this time, the target service data stored in the cache node of the second region can be sent to the computing power node of the second region, so that the computing power node of the second region processes the target service data, which can ensure the continuity and efficiency of data processing, and at the same time, the idle resources of the network are utilized, and the delay and waiting time in the data processing process are reduced.
