[0041] Computing power has become a new focus of global strategic competition and an important engine for the development of the national economy. The computing power level of countries around the world is positively correlated with economic development. With the development of 5th generation mobile networks (5G), edge computing, artificial intelligence and other technologies, the process of digital transformation in various fields is gradually accelerating. With the in-depth development of the technological revolution and industrial reform, an era of computing power as the core productivity is accelerating, and computing power has become the cornerstone of social digital transformation. As the main artery connecting users, data and computing power, the transmission network is increasingly integrated with computing power networks. Currently, major operators are accelerating the layout of computing power networks, continuously exploring the evolution of cloud network integration to computing network integration, coordinating the deep integration of data centers, cloud computing, edge computing and networks, and building an intelligent computing power ecosystem centered on computing network integration, to gain a differentiated advantage in the computing power era.

[0042] With the rapid development of cloud network business and continuous innovation in applications, cloud network integration is entering a period of vigorous development, but it still faces the following challenges in connection, experience, operation and security.

[0043] First, multi-cloud access and connection follow-up. The network needs to have wide coverage and agile access capabilities to meet customers' demand for quickly obtaining content on demand, while cloud and network work together to achieve simultaneous start and stop of cloud and network business, and to adjust on demand based on customer needs.

[0044] Second, deterministic experience is a necessity, and experience follows. Experience network requires the network to provide multiple slices based on different service level agreement (SLA) demands such as bandwidth and latency of business, and to adjust flexibly on demand to achieve one network carrying thousands of industries. Cloud network business should have quality measurement capability, and cloud network business should be visible and measurable, with fault positioning and delimitation, and business optimization capability.

[0045] Third, the integrated service capability of full online. Cloud network convergence can provide application selection, online service, and fast connection between end customers and content, and provide firewall (FW) / distributed denial of service (DDOS) / deep packet inspection (DPI) protection value-added services, and improve customer business perception.

[0046] Fourth, integrated security solutions. Future cloud network convergence solutions not only ensure the security of cloud and network, but also provide security services for users in cloud network scenarios, from network to business, to build a three-dimensional security guarantee.

[0047] According to the above, with the development of MEC, AI and other technologies, the network needs to provide more intelligent services for the efficient collaboration of cloud, edge and end computing power. Computing and network will be deeply integrated. However, the traditional network cannot provide a unified and reliable transmission scheme for different levels of business and cannot realize flexible scheduling of business.

[0048] In order to solve the problem that the prior art cannot provide a unified and reliable transmission scheme for different levels of business and cannot realize flexible scheduling of business, the present application provides a business transmission system as shown in Figure 2 The system includes a scheduling platform, a mobile edge computing (MEC) server, a computing power node and a terminal. The MEC server and the computing power node are used to process the business of the terminal. The terminal and the MEC server are connected through multiple transmission channels. The MEC server and the computing power node are connected through multiple transmission networks.

[0049] Among them, the scheduling platform arranges and optimizes the business of the terminal through the algorithm network. The scheduling platform faces various products and provides algorithm network resource autonomous scheduling service. The terminal can propose requirements to the scheduling platform according to different product types through a one-stop service platform portal. The scheduling platform can determine the business computing power requirement and bandwidth requirement of the terminal. The scheduling platform can determine the network node of the business according to the business computing power requirement of the terminal and the available computing power resource of the MEC. After determining the network node of the business, the scheduling platform can determine at least one of the transmission channel and the transmission network of the business according to the network node of the business, the bandwidth requirement of the business and the preset bandwidth threshold.

[0050] The plurality of MEC servers can provide their own available computing resources to the scheduling platform, and when the network node of the service is scheduled to the MEC server, the MEC server calculates the service and feeds back the calculation result; for the service entering the MEC server for calculation, the scheduling platform can select optical transport network (OTN) access network, passive optical network (PON) access network, 5G access network and other types of differentiated access network for the service according to the bandwidth requirement of the service. It can be understood that: for high-quality algorithm network services, the bandwidth delay requirement is relatively high, and the OTN access network is used to access the MEC server, and then the end-to-end hard channel connection is realized; for low-cost algorithm network services, which are sensitive to price, the PON access network can be used to access the MEC server; at the same time, for services without wired resources nearby, the 5G access network can be used to access the MEC server, and an end-to-end 5G slice channel is provided for access at any time and any place.

[0051] If the MEC server cannot meet the computing power requirement of the service, the service enters the computing power node for calculation, when the bandwidth requirement of the service is greater than or equal to a preset bandwidth threshold, the service uses flexible Ethernet (FlexE) hard slice technology to transmit through the intelligent metropolitan area network and the second backbone network when the service enters the computing power node from the MEC server; wherein the second backbone network is a cloud backbone network in the embodiment of the application; the intelligent metropolitan area network and the cloud backbone network are connected through the core device of the intelligent metropolitan area network.

[0052] When the bandwidth requirement of the service is less than the preset bandwidth threshold, the service does not provide a slice channel through the IP metropolitan area network and the first backbone network when the service enters the computing power node from the MEC server; wherein the first backbone network includes a 169 backbone network, a 163 backbone network and a CMNET network; the IP metropolitan area network and the first backbone network are connected through the core device of the IP metropolitan area network.

[0053] The computing power node includes a public computing power pool and an industry computing power pool, the public computing power pool refers to a computing power pool calculated according to public computing power resources and platforms; the industry computing power pool refers to a computing power pool calculated according to exclusive and dedicated computing power resources and platforms. For some services with large calculation amount but for public service type, they enter the public computing power pool for calculation, and for some services with large calculation amount but for special service type, they enter the industry computing power pool for calculation.

[0054] Based on the above technical solution, this application constructs a service transmission system. A terminal submits a service request, and the scheduling platform determines the bandwidth and computing power requirements of the service, as well as the available computing power resources from the MEC server. Based on the service's computing power requirements and the MEC server's available computing power resources, the network node for the service is determined, enabling flexible scheduling of service transmission and providing optimal service to the terminal. Furthermore, during the scheduling process, the scheduling platform can flexibly match the corresponding transmission channel and transmission network according to the service's bandwidth requirements, achieving integrated cloud-network-edge capabilities of "one network connecting multiple clouds, one-click network adjustment of the cloud."

[0055] The above describes the service transmission system provided in the embodiments of this application.

[0056] The following describes the service transmission method provided in the embodiments of this application.

[0057] like Figure 3 The diagram shown is a flowchart of a service transmission method provided in this application. The service transmission method provided in this application can be applied to, for example... Figure 2 In the service transmission system shown, the service transmission device can determine whether the network node processing the service is an MEC server or a computing power node based on the service's computing power requirements and the available computing power resources of the acquired MEC server. Then, based on the service's bandwidth requirements, preset bandwidth thresholds, and the network node processing the service, it can determine at least one of the following: the transmission channel and the transmission network. When the service's network node is an MEC server, only the transmission channel needs to be determined. If the service's network node is a computing power node, both the transmission channel and the transmission network need to be determined, thereby enabling flexible scheduling of different services.

[0058] The following provides a detailed description of the service transmission method provided in the embodiments of this application, such as... Figure 3 As shown, the service transmission method can be implemented through the following S301-S304.

[0059] S301, The service transmission device determines the computing power and bandwidth requirements of the service.

[0060] In one possible implementation, a service can also be understood as a service request from a terminal. The service transmission device can determine the computing power and bandwidth requirements of the terminal's service request based on the service request.

[0061] For example, a bank A and a large supermarket B propose a business service request, and the computing power requirements of the bank A and the large supermarket B include virtual CPU (vCPU) computing resource requirements, memory resource requirements, storage area network (SAN) resource requirements, block storage resource requirements, network attached storage (NAS) resource requirements, and object storage service (OBS) resource requirements.

[0062] The business transmission device determines that the bandwidth requirement of the business service request of the bank A is 1.4G, and determines that the vCPU computing resource requirement of the bank A is a core, the memory resource requirement is b GB, the SAN resource requirement is c TB, the block storage resource requirement is d TB, the NAS storage resource requirement is e TB, and the OBS resource requirement is f TB.

[0063] The business transmission device determines that the bandwidth requirement of the business service request of the large supermarket B is 0.8G, and determines that the vCPU computing resource requirement of the large supermarket B is m core, the memory resource requirement is n GB, the SAN resource requirement is o TB, the block storage resource requirement is p TB, the NAS storage resource requirement is q TB, and the OBS resource requirement is r TB.

[0064] S302, the business transmission device acquires the available computing power resources of the MEC server.

[0065] For example, the business transmission device acquires the available computing power resources of the MEC server, which can be understood as that the MEC server sends the remaining allocable computing power resources to the business transmission device, and the remaining allocable computing power resources of the MEC server include vCPU computing resource requirements, memory resource requirements, SAN resource requirements, block storage resource requirements, NAS storage resource requirements, and OBS resource requirements; wherein the allocable vCPU computing resource requirement of the MEC server is g core, the allocable memory resource requirement of the MEC server is h GB, the allocable SAN resource requirement of the MEC server is e TB, the allocable block storage resource requirement of the MEC server is j TB, the allocable NAS storage resource requirement of the MEC server is k TB, and the allocable OBS resource requirement of the MEC server is l TB.

[0066] S303, the business transmission device determines the network node for processing the business according to the computing power requirements of the business and the available computing power resources of the MEC server.

[0067] The network node is one of the MEC server or the computing power node.

[0068] In one possible implementation, the service transmission device compares the computing power requirement of the terminal service request with the available computing power resource of the MEC server, determines whether the available computing power resource of the MEC server can meet the computing power requirement of the terminal service request, and further determines the network node of the terminal service request to be the MEC server or the computing power node.

[0069] For example, the service transmission device compares the computing power requirement of a large supermarket B with the available resource of the MEC server, determines that the available computing power resource of the MEC server can meet the computing power requirement of the large supermarket B, and further determines the network node of the service of the large supermarket B to be the MEC server.

[0070] The service transmission device compares the computing power requirement of a bank A with the available resource of the MEC server, determines that the available computing power resource of the MEC server cannot meet the computing power requirement of the bank A, and further determines the network node of the service of the bank A to be the computing power node.

[0071] S304. The service transmission device determines at least one of a transmission channel and a transmission network for transmitting the service according to a bandwidth requirement of the service, a preset bandwidth threshold, and a network node for processing the service.

[0072] In one possible implementation, the service transmission device compares the bandwidth requirement of the terminal service request with the preset bandwidth threshold of the service transmission device, determines whether the bandwidth requirement of the terminal service request exceeds the preset bandwidth threshold of the service transmission device, and further determines at least one of the transmission channel and the transmission network for transmitting the terminal service request according to the network node for processing the terminal service request. It is worth noting that if the network node for processing the terminal service request is the MEC server, only the transmission channel for transmitting the terminal service request needs to be determined; if the network node for processing the terminal service request is the computing power node, both the transmission channel and the transmission network for transmitting the terminal service request need to be determined.

[0073] The technical solutions provided by the above embodiments bring at least the following beneficial effects: the service transmission method provided in this application allows the service transmission device to determine whether the network node processing the service is an MEC server or a computing power node based on the service's computing power requirements and the available computing power resources of the acquired MEC server. Then, based on the service's bandwidth requirements, a preset bandwidth threshold, and the network node processing the service, it determines at least one of the transmission channel and transmission network for transmitting the service. When the network node of the service is an MEC server, only the transmission channel for transmitting the service needs to be determined. If the network node of the service is a computing power node, both the transmission channel and the transmission network need to be determined. This achieves the purpose that traditional networks cannot achieve, providing a unified and reliable transmission scheme for different levels of services and enabling flexible service scheduling.

[0074] The following will describe in detail the service transmission method provided in the embodiments of this application with reference to specific examples. This method is applied in a service transmission device.

[0075] Combination Figure 3 ,like Figure 4 As shown, in S303, the network nodes for processing services are determined based on the computing power requirements of the business and the available computing power resources of the MEC server. This can be achieved through the following steps:

[0076] S401. When the available computing power resources of the MEC server meet the computing power requirements of the service, the service transmission device determines the network node for processing the service as the MEC server.

[0077] Based on the examples in S301 and S302 above, the service transmission device determines the computing power requirements of a large supermarket B and the available computing power resources of the MEC server.

[0078] Optionally, the service transmission device determines the network node of a large supermarket B based on the computing power requirements of the large supermarket B determined in S301 and the available computing power resources of the MEC server determined in S302, and the determination must satisfy the following formula:

[0079] IF(AND(mg>=0, nh>=0, oi>=0, pj>=0, qk>=0, rl>=0), "Requirements met");

[0080] At this point, the values ​​of the computing resource requirements, memory resource requirements, SAN resource requirements, block storage resource requirements, NAS storage resource requirements, and OBS resource requirements of a large supermarket B, minus the corresponding computing resource requirements, memory resource requirements, SAN resource requirements, block storage resource requirements, NAS storage resource requirements, and OBS resource requirements of the MEC server, are all greater than or equal to zero. Therefore, the available computing power resources of the MEC server can meet the computing power requirements of the large supermarket B, and the network node of the large supermarket B is the MEC server. (The parameter definitions in this step refer to the parameter definitions in S301 and S302 above, and will not be repeated here).

[0081] S402. If the available computing power resources of the MEC server are insufficient to meet the computing power requirements of the service, the network node that processes the service shall be designated as the computing power node.

[0082] Based on the examples in S301 and S302 above, the service transmission device determines the computing power requirements of a certain bank A and the available computing power resources of the MEC server.

[0083] Optionally, the service transmission device determines the network node of bank A based on the computing power requirements of bank A as determined in S301 and the available computing power resources of the MEC server as determined in S302, and the determination must satisfy the following formula:

[0084] IF(AND(ag>=0, bh<0, ci>=0, dj>=0, ek>=0, fl>=0), "Demand not met");

[0085] At this point, if the computing resource requirements, memory resource requirements, SAN resource requirements, block storage resource requirements, NAS storage resource requirements, and OBS resource requirements of bank A are subtracted from the corresponding computing resource requirements, memory resource requirements, SAN resource requirements, block storage resource requirements, NAS storage resource requirements, and OBS resource requirements of the MEC server, respectively, and the memory resource requirements of bank A after subtracting the memory resource requirements of the MEC server are less than zero, then the available computing power resources of the MEC server cannot meet the computing power requirements of bank A. Therefore, the network node of bank A is designated as the computing power node. (The parameter definitions in this step refer to the parameter definitions in S301 and S302 above, and will not be repeated here.)

[0086] Based on the above technical solution, the service transmission method provided in this application embodiment allows the service transmission device to obtain the computing power requirements of the service and the available computing power resources of the MEC, thereby determining whether the available computing power resources of the MEC can meet the computing power requirements of the service, realizing flexible scheduling of different services, and avoiding the waste of computing power and insufficient computing power.

[0087] The implementation of the step embodiment of determining the network node for processing the service is described in detail above.

[0088] In the following, the service transmission device how to determine the computing node of the service as a public computing pool or an industry computing pool will be described in detail in combination with specific embodiments.

[0089] As shown in Figure 5 , how to determine the computing node of the service as a public computing pool or an industry computing pool is specifically implemented by steps S501-S502, which will be described in detail below:

[0090] S501, the service transmission device determines the computing node for processing the service as a public computing pool when the service is a public service type service.

[0091] Among them, the public computing pool refers to a computing pool for operation according to public computing resources and platforms.

[0092] For example, the network node of a large shopping mall is a computing node, and the service request of the large shopping mall is a public service type service, so the service of the large shopping mall enters the public computing pool for calculation.

[0093] S502, the service transmission device determines the computing node for processing the service as an industry computing pool when the service is a special service type service.

[0094] Among them, the industry computing pool refers to a computing pool for operation according to exclusive computing resources and platforms.

[0095] For example, the network node of a certain bank A is a computing node, and the service request of the certain bank A is a special service type service, so the service of the certain bank A enters the industry computing pool for calculation.

[0096] The present application divides the computing node into a public computing pool and an industry computing pool, realizes the special service of the service, and distinguishes some special service from ordinary service to avoid mutual interference.

[0097] The above describes in detail how the service transmission device determines the computing node of the service as a public computing pool or an industry computing pool.

[0098] In the following, the service transmission device how to determine the computing node of the service as a public computing pool or an industry computing pool will be described in detail in combination with specific embodiments.

[0099] As shown in Figure 6 , how to determine the computing node of the service as a public computing pool or an industry computing pool is specifically implemented by steps S501-S502, which will be described in detail below:

[0100] S601, the service transmission device determines to transmit the service according to the transmission channel when the network node is a MEC server.

[0101] If the bandwidth requirement of the service is greater than or equal to the preset bandwidth threshold, the transmission channel for transmitting the service is determined to be an OTN access network.

[0102] If the bandwidth requirement of the service is less than the preset bandwidth threshold, the transmission channel for transmitting the service is determined to be a PON access network.

[0103] In combination with the examples in S301 and S303, the bandwidth requirement of the service request of a large supermarket B is 0.8G. At this time, the preset bandwidth threshold is 1G, and the bandwidth requirement of the service request of the large supermarket B is 0.8G. According to the comparison, it is determined in S303 that the network node of the large supermarket B is a MEC server, so only the transmission channel of the large supermarket B needs to be determined. Specifically, when the bandwidth requirement of the service is less than the preset bandwidth threshold, the transmission channel of the service adopts a PON access network.

[0104] It can be understood that there is still a third case at this time, the network node of a service D is a MEC server, but the bandwidth requirement of the service D is greater than or equal to the preset bandwidth threshold, so the transmission channel of the service D is an OTN access network.

[0105] S602, the service transmission device determines to transmit the service according to the transmission channel and the transmission network when the network node is a computing power node.

[0106] If the bandwidth requirement of the service is greater than or equal to the preset bandwidth threshold, the transmission channel for transmitting the service is determined to be an OTN access network, and the transmission network is an intelligent metropolitan area network and a second backbone network.

[0107] If the bandwidth requirement of the service is less than the preset bandwidth threshold, the transmission channel for transmitting the service is determined to be a PON access network, and the transmission network is an IP metropolitan area network and a first backbone network.

[0108] In combination with the examples in S301 and S303, the preset bandwidth threshold in the service transmission device is 1G, and the bandwidth requirement of the service request of a bank A is 1.4G. At this time, the preset bandwidth threshold is 1G, and the bandwidth requirement of the service request of the bank A is 1.4G. According to the comparison, it is determined in S303 that the network node of the bank A is a computing power node, so the transmission channel and the transmission network of the bank A need to be determined. Specifically, when the bandwidth requirement of the service is greater than or equal to the preset bandwidth threshold, the transmission channel of the service adopts an OTN access network, and the transmission network adopts an intelligent metropolitan area network and a second backbone network for transmission. The second backbone network is a cloud backbone network in the embodiment of the application; and the intelligent metropolitan area network and the cloud backbone network are connected through the core device of the intelligent metropolitan area network.

[0109] Understandably, a fourth scenario still exists: a network node for service C is a computing node, but the bandwidth requirement of service C is less than a preset bandwidth threshold. In this case, the transmission channel for service C is a PON access network, and the transmission network consists of an IP metropolitan area network and a first backbone network. The first backbone network includes the 169 backbone network, the 163 backbone network, and the CMNET network; the IP metropolitan area network and the first backbone network are interconnected through core equipment of the intelligent metropolitan area network.

[0110] Understandably, there is still a fifth scenario: for services without nearby wired resources, a 5G access network can be used to access the MEC server, and an end-to-end 5G slicing channel can be provided for access anytime, anywhere.

[0111] Based on the above technical solutions, the service transmission method provided in this application embodiment determines at least one of the service transmission channel and transmission network through the service bandwidth requirements, preset bandwidth thresholds and service network nodes, and then realizes ubiquitous high-speed access through the transmission channel. It provides OTN access network, PON access network and 5G access network according to the service requirements, and is software and hardware isolated from conventional services. For services that need to enter the computing power node for calculation, it provides flexible and high-speed basic support through the transmission network.

[0112] This application embodiment can divide the service transmission device into functional modules or functional units according to the above method examples. For example, each function can be divided into a separate functional module or functional unit, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or in software functional modules or functional units. The module or unit division in this application embodiment is illustrative and represents only one logical functional division; other division methods may be used in actual implementation.
