[0058] A call bill 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 article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0060] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0061] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. 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 may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0062] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[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, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0064] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0065] "East Data West Computing" refers to the East Data West Computing Project, which refers to the orderly guidance of the computing power demand in the east to the west through the construction of a new computing power network system integrating data centers, cloud computing, and big data, optimizing the layout of data center construction, and promoting the coordinated linkage between the east and the west, aiming to solve the problem of uneven distribution of computing power resources in the east and west of China. Specifically, "East Data" refers to the huge amount of data in the eastern region, and "West Computing" refers to the relatively surplus computing power resources in the western region. Although the eastern region has dense data center construction, the digital economy is developing rapidly, and the demand for computing power is large, 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-West Computing Project and the continuous development of computing power networks, computing power resources have become the key to future industrial development. Users in the eastern region need to send large amounts of data to computing power hub nodes in the western region, and the data will be sent from the eastern region to the west through the backbone network. How to make full use of the limited bandwidth resources of the backbone network and efficiently transmit the massive data provided by the eastern computing power business to the west while ensuring the smooth operation of the network has become a problem that needs to be solved urgently.

[0067] The existing technology only considers the allocation, scheduling and routing of computing resources, and uses transmission links with less load to distribute data to relatively idle computing hub nodes, without considering the impact of massive data transmission on the backbone network bandwidth of operators. For example, sending data to other devices in the same communication network that can communicate with each other, or sending data to the western region through different paths (routes) through non-shortest paths (minimum routing hops), without considering the problem of network utilization when it is busy and idle, and the problem of unbalanced uplink and downlink utilization in the metropolitan area network, which affects the efficiency of data transmission.

[0068] In response to the above technical problems, the present application provides a data transmission method, which is applied to a cache node, and the cache node is connected to a core router (CR) device. The idea is to: receive the target business data to be processed in the first area; the target business data is the data that needs to be transmitted to the computing power node in the second area for processing; store the target business data; and send the target business data when the preset transmission conditions are met. It can be seen that the present application introduces a cache node to temporarily store the target business data that needs to be transmitted across regions, and determines whether to send the target business data according to the preset transmission conditions. In this way, the target business data can be temporarily stored when it is not conducive to data transmission, and the target business data can be sent when the transmission conditions are met. This fully considers the data transmission requirements in different situations and can improve the efficiency of data transmission.

[0069] The data transmission method provided in the embodiments of the present application is described in detail below in conjunction with the accompanying drawings.

[0070] Figure 1 The network architecture diagram of the urban broadband core network is shown in Figure 2. Figure 1 As shown, the network includes:

[0071] Backbone network refers to the high-speed network trunk lines that connect multiple cities or regions. In the "East Data West Computing" project, the role of backbone network is particularly critical. It is responsible for connecting the data-intensive areas in the east and the computing resources in the west to ensure that data can be transmitted efficiently and quickly.

[0072] A core router (CR), also known as a backbone router, is a very critical device in the network architecture. It is responsible for processing and forwarding a large number of data packets to ensure the smooth flow of information.

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

[0074] Broadband Network Gateway (BNG) is responsible for access management of broadband users. BNG includes: User Plane (UP) equipment and Control Plane (CP) equipment. Among them, CP equipment is mainly responsible for user authentication, authorization, address allocation and other management functions, while UP equipment is mainly responsible for processing user data traffic forwarding, including traffic reception, forwarding and status 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 exchanging data packets, and performing local routing, filtering, traffic balancing, QoS priority management and security mechanism processing according to traffic requirements.

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

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

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

[0079] For the urban broadband core network, end users access the operator's ONU equipment through optical modems, which are then aggregated and connected to the community's OLT equipment, and then connected to the UP equipment in the area (depending on the number of cells in the area, access is made after aggregation through an aggregation switch or direct access), the UP equipment is connected to the CR equipment, and through the CR equipment, it is connected to the backbone network or accesses the local city's CDN resources.

[0080] The present application introduces a cache node in the above network architecture to implement the data transmission method provided in the embodiments of the present application. In some embodiments, the cache node includes a memory for storing a large amount of computing power business data involved in the East-West computing scenario, and the cache node also includes a processor for pre-processing the computing power business data, or determining whether to send the computing power business data by judging whether the preset transmission conditions are met.

[0081] Figure 2 A schematic diagram of a network architecture provided in an embodiment of the present application. Figure 2 As shown, the cache node is connected to the 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 intended 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. It is known to those skilled in the art 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 following is a detailed introduction to the data transmission method provided in the embodiment of the present application.

[0084] Figure 3 A flowchart of a data transmission method provided in an embodiment of the present application is applied to Figure 2 The cache nodes shown are Figure 3 As shown, the method includes:

[0085] S101: Receive target service data to be processed in a first area.

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

[0087] For example, the first region is a region with rapid economic development, large data generation, and relatively high demand for computing power; the second region is a region with abundant energy and low operating costs, and has the ability to develop data centers and provide computing services.

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

[0089] S102: Store target business data.

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

[0091] S103: When the preset transmission conditions are met, the target service data is sent.

[0092] In some embodiments, the preset transmission condition is determined based on the requirement for the network status parameter. For example, the network status parameter may be bandwidth utilization, etc.

[0093] It can be understood that setting preset transmission conditions can ensure that the network used to transmit data is in an ideal state when sending target business data, thereby ensuring that the process of transmitting target business data is stable and unimpeded, and achieving efficient information flow.

[0094] In some embodiments, 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: sending the preprocessed target service data.

[0095] Exemplarily, preprocessing the target business data includes preprocessing the unsupervised learning computing business data to optimize the data processing process and improve the subsequent computing efficiency. For example, the principal component analysis (PCA) technology can be used to reduce the dimensionality of high-dimensional data, thereby reducing the computational complexity and extracting the most important features. Or the data can be grouped through a clustering algorithm to group similar data points 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, such as video data.

[0097] In some embodiments, the above storage nodes can be established based on existing CDN nodes.

[0098] It can be understood that the cache node provided in the embodiment of the present application can be used by users to store data in the CDN, or the cache node can be established based on the original CDN node to achieve storage device sharing, maximize the use of network bandwidth (uplink and downlink bandwidth), and save operator network construction costs.

[0099] In summary, the data transmission method provided by the embodiment of the present application has at least the following beneficial effects: the present application introduces a cache node to temporarily store target business data that needs to be transmitted across regions, and determines whether to send the target business data based on preset transmission conditions. In this way, the target business data can be temporarily stored when it is not conducive to data transmission, and the target business data can be sent when the transmission conditions are met. This fully considers the data transmission requirements in different situations and can improve the efficiency of data transmission.

[0100] The implementation of step S103 is described below in combination with different application scenarios.

[0101] As a possible implementation method, the data transmission method provided in the present application is applied to the cache node of the first area, and the cache node of the first area is connected to the CR device of the first area; the above step S103 can be specifically implemented as follows: when the first preset transmission condition is met, the target business data is sent to the computing power node of the second area through the CR device and the backbone network device of the first area in turn.

[0102] Among them, the first preset transmission condition includes: the bandwidth utilization between the CR device in the first area and the backbone network device is less than or equal to the first preset threshold; the bandwidth utilization between the backbone network device and the computing power node in the second area is less than or equal to the second preset threshold.

[0103] Among them, the first preset threshold and the second preset threshold may be equal, or the first preset threshold and the second preset threshold may be unequal, which is not limited in the present application. Exemplarily, the first preset threshold is 50% and the second preset threshold is 50%.

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

[0105] As another possible implementation method, the data transmission method provided in the present application is applied to the cache node of the first area, and the cache node of the first area is connected to the CR device of the first area; the above step S103 can be specifically implemented as follows: when the second preset transmission condition is met, the target business data is sent to the cache node of the second area through the CR device of the first area, the backbone network device and the CR device of the second area in sequence, so that the cache node of the second area stores the target business data.

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

[0107] It is understandable that, when the second preset transmission condition is met, the network between the CR equipment and the backbone network equipment in the first area is in a relatively idle state, and has the ability to transmit a large amount of data from the first area to the second area, but the network between the backbone network and the computing power nodes in the second area is in a relatively busy state and does not have the ability to transmit a large amount of data, so the target business data needs to be sent to the cache node in the second area. Such a transmission strategy can ensure the timeliness of data transmission and avoid the risks of transmission delays or data loss that may be caused by network busyness.

[0108] As another possible implementation method, the data transmission method provided in the present application is applied to the cache node of the first area, and the cache node of the first area is connected to the CR device of the first area; the above step S103 can be specifically implemented as follows: when the current time is within the first preset time period, the target business data is sent to the computing power node of the second area through the CR device and the backbone network device of the first area.

[0109] Among them, the first preset time period represents the idle time period of the backbone network. The specific time period is determined according to the actual network conditions in different areas. Exemplarily, the first preset time period can be from 23:00 on the same day to 7:00 on the next day.

[0110] As another possible implementation method, the data transmission method provided in the present application is applied to the cache node of the second area, and the cache node of the second area is connected to the CR device of the second area; the above step S103 can be specifically implemented as follows: when the third preset transmission condition is met, the target business data is sent to the computing power node of the second area through the CR device and the backbone network device of the second area in turn.

[0111] Among them, the third preset transmission condition includes: the bandwidth utilization between the CR device in the second area and the backbone network device is less than or equal to the third preset threshold; the bandwidth utilization between the backbone network device and the computing power node in the second area is less than or equal to the second preset threshold.

[0112] Among them, the second preset threshold and the third preset threshold may be equal, or the second preset threshold and the third preset threshold may be unequal, which is not limited in the present application. Exemplarily, the second preset threshold is 50% and the third preset threshold is 50%.

[0113] It can be understood that when the third preset transmission condition is met, the network between the CR device and the backbone network device in the second area, as well as the network between the backbone network device and the computing power node in the second area, are both in a relatively idle state and have the ability to transmit large amounts of data. At this time, the target business data stored in the cache node in the second area can be sent to the computing power node in the second area, so that the computing power node in the second area processes the target business data, thereby ensuring the continuity and efficiency of data processing, while utilizing the idle resources of the network to reduce delays and waiting time in the data processing process.

[0118] As a possible implementation method, the above step S202 can be specifically implemented as follows: when the first preset transmission condition is met, the target business data is sent to the computing power node in the second area through the backbone network device.

[0119] Among them, the first preset transmission condition includes: the bandwidth utilization between the CR device in the first area and the backbone network device is less than or equal to the first preset threshold, and the bandwidth utilization between the backbone network device and the computing power node in the second area is less than or equal to the second preset threshold.

[0120] As another possible implementation method, the above step S202 can be specifically implemented as follows: when the second preset condition is met, the target business data is sent to the cache node of the second area through the backbone network device and the CR device of the second area in sequence, so that the cache node of the second area stores the target business data.

[0121] Among them, the second preset transmission condition includes: the bandwidth utilization between the CR device in the first area and the backbone network device is less than or equal to the first preset threshold, and the bandwidth utilization between the backbone network device and the computing power node in the second area is greater than the second preset threshold.

[0122] S203: When the preset transmission condition is not met, determine a target cache node, and send the target service data to the target cache node for storage.

[0123] The target cache node is used to store target business data and send the target business data when a preset transmission condition is met.

[0125] S301: Obtain bandwidth utilization between a CR device in a first area and a CR device in a second area, storage utilization of a first cache node, and storage utilization of a second cache node.

[0126] The first cache node is connected to the CR device in the first area, and the second cache node is connected to the CR device in the second area.

[0127] In some embodiments, the CR device in the first area obtains the storage utilization of the second cache node through the CR device in the second area.

[0128] S302: Determine a target cache node from the first cache node and the second cache node based on the bandwidth utilization between the CR device in the first area and the CR device in the second area, the storage utilization of the first cache node and the storage utilization of the second cache node.

[0129] The target cache node is used to store target business data and send the target business data when a preset transmission condition is met.

[0130] As a possible implementation, Figure 6 As shown, the above step S302 can be implemented as S3021: when the bandwidth utilization between the CR device in the first area and the CR device in the second area is less than or equal to a preset threshold, determine the cache node with lower storage utilization in the first cache node and the second cache node as the target cache node.

[0131] As another possible implementation, Figure 6 As shown, the above step S302 can also be implemented as S3022: when the bandwidth utilization between the CR device in the first area and the CR device in the second area is greater than a preset threshold, determine the first cache node as the target cache node. Exemplarily, the preset threshold of the bandwidth utilization between the CR device in the first area and the CR device in the second area can be 70%.

[0132] In some embodiments, when the target cache node is the second cache node, the CR device in the first area sends the target service data to the second cache node through the CR device in the second area.

[0139] S4021. Determine a target UP device based at least on an uplink bandwidth utilization rate between the network access device and the UP device.

[0140] In some embodiments, when the uplink bandwidth utilization between the network access device and the first UP device currently in use is greater than a fourth preset threshold, a UP device whose uplink bandwidth utilization between the network access device and the network access device is less than or equal to a fifth preset threshold is selected from multiple UP devices as the target UP device.

[0141] Exemplarily, the fourth preset threshold may be 70%, and the fifth preset threshold may be 30%.

[0142] As another possible implementation, the present application selects a UP device having the smallest uplink bandwidth utilization between the CR device and a plurality of UP devices as the target UP device.

[0143] In other embodiments, when the uplink bandwidth utilization between the network access device and the first UP device currently in use is less than or equal to a fourth preset threshold, the uplink bandwidth utilization between the first UP device and the CR device is determined; when the uplink bandwidth utilization between the first UP device and the CR device is greater than a sixth preset threshold, a UP device whose uplink bandwidth utilization between the CR device and the CR device is less than or equal to the fourth preset threshold is selected from multiple UP devices as the target UP device.

[0144] Exemplarily, the fourth preset threshold may be 70%, and the sixth preset threshold may be 20%.

[0146] As another possible implementation, the present application selects a UP device having the smallest uplink bandwidth utilization between the CR device and a plurality of UP devices as the target UP device.

At the same time, by dynamically selecting UP devices, the method can adapt to different changes in network conditions, thereby enhancing the flexibility and adaptability of the method.

[0148] S4022: Determine a target CR device based on the uplink bandwidth utilization between the target UP device and the CR device.

[0149] Exemplarily, among a plurality of CR devices included in the city bandwidth core network, the CR device having the smallest uplink bandwidth utilization rate with the target UP device is used as the target CR device.

[0150] S403: Control the target UP device to transmit the target service data to the target CR device through the target uplink, so that the target CR device sends the target service data to the target cache node.

[0151] The target cache node is used to store target business data and send the target business data when preset transmission conditions are met.

[0152] In some embodiments, controlling the target UP device to transmit the target service data to the target CR device via the target uplink includes: controlling the target UP device to receive the target service data from the network access device, and controlling the target UP device to send the target service data to the target CR device.

[0154] The following is an introduction to a data transmission method of an embodiment of the present application based on a specific embodiment, and the method includes the following steps:

[0155] S1: A terminal user in the first area sends target service data to a network access device.

[0156] S2: The CP device in the first area determines a target uplink between the network access device and the CR device for the target service data to be processed based on the uplink bandwidth utilization.

[0157] Specifically, the target UP device is determined based on the uplink bandwidth utilization between the network access device and the UP device; the target CR device is determined based on the uplink bandwidth utilization between the target UP device and the CR device.
