[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations; and the acquisition, storage, processing, transmission, etc. of data must comply with relevant laws and regulations.

[0058] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0059] When using cloud dedicated lines to transmit financial information to the cloud resource pool, a fixed transmission protocol is usually used to transmit the information to the cloud resource pool. This means that the transmission link in the cloud resource pool needs to match the fixed transmission protocol. However, when the transmitted information needs to use another transmission protocol, it may not be possible to find a suitable transmission link to transmit the information to the cloud resource pool, which limits the information transmission scenario and leads to low reliability of information transmission.

[0060] In view of this, the present application provides an information transmission method, which can be applied in the application environment shown in Figure 1. The information transmission system includes a software-defined network (SDN) cloud controller 102, an information source 104, and a cloud resource pool set 106 connected to the information source 104, and the cloud resource pool set 106 includes multiple cloud resource pools.

[0061] Specifically, the SDN cloud controller 102 obtains an information transmission request sent by the information source 104, and determines multiple cloud resource pools connected to the information source, each of which is deployed with a candidate transmission link; parses the information transmission request, obtains the target information that the information source expects to transmit, and based on the information transmission protocol used when transmitting the target information, determines from each candidate transmission link a target transmission link that matches the target information, a target gateway is deployed on the target transmission link, and then controls the target transmission link to transmit the target information based on the target gateway.

[0062] In one embodiment, as shown in FIG. 2 , an information transmission method is provided, which is described by taking the method applied to a software defined network (SDN) cloud controller as an example, and includes the following steps:

[0063] S202, obtaining an information transmission request sent by an information source, and determining multiple cloud resource pools connected to the information source, each cloud resource pool being deployed with a candidate transmission link.

[0064] The information source refers to the sender of the target information, and the form of the information source is not limited. For example, the information source can refer to the Internet Data Center (IDC) of the market center, or it can refer to various business systems.

[0065] A candidate transmission link refers to a link in the cloud resource pool used to transmit target information. The number of candidate transmission links can be one or more. When the candidate transmission links are different, the devices deployed on the candidate transmission links are different. For example, each candidate transmission link includes a first transmission link and a second transmission link. If a multicast gateway is deployed on the first transmission link, the target information can be transmitted to multiple receiving devices in the cloud resource pool through the first transmission link; if a unicast gateway is deployed on the second transmission link, the target information can be transmitted to a specific receiving device in the cloud resource pool through the first transmission link.

[0066] The devices deployed in the cloud resource pool can communicate with each other through the Internet Group Management Protocol (IGMP), for example, they can communicate through IGMPv2, or they can communicate through IGMPv2, or they can communicate in other ways corresponding to other protocols. There is no limit to the way to determine the multiple cloud resource pools connected to the information source. For example, based on the mapping relationship between the information source identifier and the cloud resource pool identifier, the multiple cloud resource pools connected to the information source can be determined.

[0067] S204, parsing the information transmission request to obtain the target information that the information source expects to transmit.

[0068] Wherein, the information transmission request includes target information, and the target information that the information source expects to transmit can be obtained by parsing the information transmission request. The target information can refer to business information related to financial business, including but not limited to: securities data, stock data, futures data, etc.

[0069] S206, based on the information transmission protocol used when transmitting the target information, determine a target transmission link matching the target information from each candidate transmission link, where the target transmission link includes a target gateway.

[0070] Among them, the information transmission protocol represents the protocol used to transmit the target information. For example, the information transmission protocol includes but is not limited to: a source specific multicast (SSM) protocol based on protocol independent multicast (PIM), that is, a PIM-SSM protocol, and a sparse mode (SM) protocol based on PIM, that is, a PIM-SM protocol, and a dense mode (DM) protocol based on PIM, that is, a PIM-DM protocol, etc.

[0071] A target gateway is deployed on the target transmission link. The form of the target gateway is not limited. For example, the target gateway may include a unicast gateway, a multicast gateway, and the like.

[0072] Therein, based on the information transmission protocol used when transmitting the target information, there is no limitation on the method of determining the target transmission link matching the target information from the candidate transmission links, which is described below with examples in combination with possible implementation methods.

[0073] In one embodiment, when the information transmission protocol used in target information transmission includes a dense protocol based on protocol-independent multicast, a candidate transmission link among the candidate transmission links that matches the dense protocol is determined as a target transmission link that matches the target information.

[0074] S208, controlling the target transmission link to transmit the target information based on the target gateway.

[0075] There is no limitation on the method of transmitting the target information based on the target gateway controlling the target transmission link, and several of the methods are described below by way of example.

[0076] In one embodiment, the target gateway stores multicast group information matching the target transmission link, and based on the multicast group information, controls the target transmission link to transmit the target information to the receiving device corresponding to the multicast group information. The multicast group information refers to information related to the receiving device of the target information, and the multicast group information includes but is not limited to: the name of the receiving device, the identification of the receiving device, the physical location of the receiving device, the port of the receiving device receiving information, etc. The receiving device is also deployed in the cloud resource pool corresponding to the target transmission link. The form of the receiving device is not limited, for example, the receiving device can refer to a virtual machine, a server, etc.

[0077] In one embodiment, a device gateway corresponding to a target transmission link is determined, and multicast group information is obtained from the device gateway based on the target gateway, and the target transmission link is controlled to transmit the target information to a receiving device matching the multicast group information.

[0078] The device gateway and the receiving device matching the multicast group information are deployed in the cloud resource pool corresponding to the target transmission link, and the device gateway and the receiving device can communicate through the cloud gateway. The device gateway corresponding to the target transmission link can be determined based on the mapping relationship between the transmission link and the device gateway. The device gateway and the target gateway can communicate based on the Internet Group Management Protocol IGMP. The device gateway stores the multicast group information, and the number of the device gateway and the receiving device information can be one or more.

[0079] It should be understood that in order to meet actual needs, the number of receiving devices for information transmitted on the transmission links in the cloud resource pool may be increased or decreased. For example, it may be possible to regularly or periodically query whether there are any new receiving devices.

[0080] In one embodiment, when the target gateway sends a query message to the downstream network segment, the newly added device information matching the query message is intercepted; the multicast group information is updated based on the newly added device information. In some cases, the query message can be sent to the downstream network segment regularly or periodically. Thus, through the method of timed polling query, the dynamic changes of the entire IGMP network can be converted into a static multicast source and passed to the PIM through the SDN cloud controller to inform the target gateway.

[0081] Among them, the SDN cloud controller can report to the cloud controller, which is used to intercept the newly added device information matching the query message. The query message is used to inquire whether there is a newly added receiving device, and the newly added device information refers to the information related to the newly added receiving device. Therefore, when the newly added device information matching the query message is intercepted, the target information can be transmitted to the original receiving device and the newly added receiving device based on the updated multicast group information, thereby improving the accuracy of information transmission.

[0082] In some cases, when receiving the success information fed back by the receiving device corresponding to the target information, the receiving time of the success information is recorded, and the success information is used to indicate that the receiving device successfully receives the target information. The number of receiving devices corresponding to the target information is not limited, for example, it can be one or more.

[0083] In some cases, the receiving device corresponding to the target information includes a first device. When the success information fed back by the first device is not received and the number of times the success information is not received reaches a preset number of times, the target gateway is instructed to delete the information corresponding to the first device in the multicast group information, or the device gateway is instructed to delete the information corresponding to the first device in the multicast group information.

[0084] In some cases, upon receiving a withdrawal request from the first device, the target gateway is instructed to delete the information corresponding to the first device in the multicast group information, or the device gateway is instructed to delete the information corresponding to the first device in the multicast group information. The withdrawal request is used to indicate that the first device actively withdraws from the multicast group corresponding to the target information.

[0085] Further, in one embodiment, when the receiving device receives a query request from a query terminal, the receiving device may output information matching the query request to the query terminal based on the stored information. The query terminal may send the query request to the receiving device based on an Elastic Load Balance mechanism.

[0086] For example, taking the receiving device as a virtual machine and the information stored in the receiving device as futures data, the user can submit a query request to the virtual machine through the query terminal, so that the virtual machine can determine the futures data that the user wants to query from the stored futures data, and output the futures data that the user wants to query through the query terminal to meet the user's query needs.

[0087] In one embodiment, the number of target transmission links may be multiple, and the multiple target transmission links include a first target link and a second target link. Specifically, in response to a query request for information in a cloud resource pool corresponding to a first target link, if a failure is detected in the cloud resource pool corresponding to the first target link, a query result matching the query request is output based on information stored in the cloud resource pool corresponding to the second target link. Thus, the high availability of the cloud resource pool can be improved.

[0088] Based on the content shown in FIG2, by obtaining the information transmission request sent by the information source and determining multiple cloud resource pools connected to the information source, each cloud resource pool is deployed with a candidate transmission link, parsing the information transmission request, obtaining the target information that the information source expects to transmit, and based on the information transmission protocol used when transmitting the target information, determining the target transmission link that matches the target information from the candidate transmission links in each cloud resource pool, the target transmission link is deployed with a target gateway, and the target transmission link can be controlled to transmit the target information based on the target gateway. Thus, by configuring multiple cloud resource pools and the information transmission protocols corresponding to the candidate transmission links in each cloud resource pool, the situation where a suitable transmission link cannot be matched due to the information transmission protocol used by the transmitted information can be avoided, the information transmission scenario is expanded, and the reliability of information transmission can be improved.

[0089] In one embodiment, based on the information transmission protocol used when transmitting the target information, an implementation method of determining a target transmission link matching the target information from each candidate transmission link (i.e., S206) may include the following steps as shown in FIG. 3:

[0090] S302, when the information transmission protocol used in target information transmission includes a designated source multicast protocol based on protocol-independent multicast, determine a candidate transmission link that matches the designated source multicast protocol from each candidate transmission link, and determine a target transmission link that matches the target information based on the determined candidate transmission link.

[0091] There is no limitation on the method of determining the candidate transmission link that matches the designated source multicast protocol from the candidate transmission links, and several of the methods are described below with examples.

[0092] In one embodiment, for each candidate transmission link, an information transmission protocol used by historical information transmitted by the candidate transmission link is determined; when the information transmission protocol used by the historical information is a specified source multicast protocol, the candidate transmission link corresponding to the historical information is determined as a candidate transmission link among the candidate transmission links that matches the specified source multicast protocol.

[0093] In one embodiment, a switch is deployed on each candidate transmission link, and the configuration parameters of the uplink port of each switch are obtained. When the configuration parameters match the preset parameters corresponding to the specified source multicast protocol, the candidate transmission link where the configuration parameters are located is determined as the candidate transmission link that matches the specified source multicast protocol among the candidate transmission links.

[0094] The implementation method of determining the target transmission link matching the target information based on the determined candidate transmission links is not limited. For example, the target transmission link matching the target information can be determined from the determined candidate transmission links based on the expected transmission mode of the target information.

[0095] In some cases, when the desired transmission mode of the target information is unicast, the candidate transmission links including the first unicast gateway among the determined candidate transmission links are determined as the target transmission links matching the target information; the target gateway includes the first unicast gateway.

[0096] The SDN cloud controller includes a dedicated line controller, which is used to transmit target information to a switch on a target transmission link, and the switch is used to send target information to a first unicast gateway, that is, a switch and a first unicast gateway are sequentially deployed on the target transmission link. The switch and the first unicast gateway can communicate based on the IGMP protocol, or based on a virtual eXtensible Local Area Network (VXLAN), or in other ways.

[0097] In one embodiment, a device gateway corresponding to a target transmission link is determined, and multicast group information is obtained from the device gateway based on a first unicast gateway, and then the target transmission link is controlled to transmit the target information to a receiving device matching the multicast group information, wherein the receiving device is also deployed in a cloud resource pool corresponding to the target transmission link.

[0098] In other cases, when the desired transmission mode of the target information is a multicast mode, the candidate transmission link including the first multicast gateway in the determined candidate transmission links is determined as the target transmission link matching the target information; the target gateway includes the first multicast gateway. The switch on the target transmission link is used to send the target information to the first multicast gateway, that is, the switch and the first multicast gateway are sequentially deployed on the target transmission link.

[0099] In one embodiment, a device gateway corresponding to a target transmission link is determined, multicast group information is obtained from the device gateway based on a first multicast gateway, and then the target transmission link is controlled to transmit the target information to a receiving device matching the multicast group information.

[0100] S304, when the information transmission protocol used in target information transmission includes a sparse protocol based on protocol-independent multicast, determine a candidate transmission link matching the sparse protocol among the candidate transmission links as a target transmission link matching the target information.

[0101] There is no limitation on the manner of determining the candidate transmission link that matches the designated source multicast protocol among the candidate transmission links, and several of the manners are described below by way of example.

[0102] In one embodiment, for each candidate transmission link, the information transmission protocol used by the historical information transmitted by the candidate transmission link is determined; when the information transmission protocol used by the historical information is a sparse protocol, the candidate transmission link corresponding to the historical information is determined as the candidate transmission link that matches the sparse protocol among the candidate transmission links.

[0103] In one embodiment, a switch is deployed on each candidate transmission link, and the configuration parameters of the uplink port of each switch are obtained. When the configuration parameters match the preset parameters corresponding to the sparse protocol, the candidate transmission link where the configuration parameters are located is determined as the candidate transmission link that matches the sparse protocol among the candidate transmission links.

[0104] Based on the method shown in FIG3 , by configuring the designated source multicast protocol based on protocol-independent multicast and the sparse protocol based on protocol-independent multicast to transmit information to the cloud resource pool, the information transmission scenario can be expanded and the reliability of information transmission can be improved.

[0105] In one embodiment, when the information transmission protocol used for target information transmission includes a sparse protocol, the candidate transmission links including the second unicast gateway and the second multicast gateway in each candidate transmission link are determined as target transmission links matching the target information; the target gateway includes the second multicast gateway.

[0106] The switch on the target transmission link is used to send the target information to the second unicast gateway, and the second unicast gateway is used to transmit the target information to the second multicast gateway. That is to say, the switch, the second unicast gateway and the second multicast gateway are sequentially deployed on the target transmission link. Therefore, when the information transmission protocol is different, the type and number of gateways deployed on the transmission link are different. Therefore, based on the information transmission protocol used when the target information is transmitted, the transmission link suitable for the target information transmission can be matched, which can improve the stability of information transmission.

[0107] Further, in one embodiment, a device gateway corresponding to the target transmission link is determined, multicast group information is obtained from the device gateway based on the second multicast gateway, and then the target transmission link is controlled to transmit the target information to a receiving device matching the multicast group information.

[0108] In combination with the above content, in one embodiment, as shown in FIG4 , a method for information transmission is provided, taking the method applied to an SDN cloud controller as an example, the method includes the following steps:

[0109] S402, obtaining an information transmission request sent by an information source, and determining multiple cloud resource pools connected to the information source, each cloud resource pool being deployed with a candidate transmission link; and each candidate transmission link being deployed with a switch.

[0110] S404, parsing the information transmission request to obtain the target information that the information source expects to transmit.

[0111] S406, when the information transmission protocol used in target information transmission includes a designated source multicast protocol based on protocol-independent multicast, obtain configuration parameters of the uplink port of each switch.

[0112] S408: When the configuration parameter matches the preset parameter corresponding to the specified source multicast protocol, the candidate transmission link where the configuration parameter is located is determined as a candidate transmission link that matches the specified source multicast protocol among the candidate transmission links.

[0113] S410, when the expected transmission mode of the target information is unicast, determine the candidate transmission links including the first unicast gateway among the determined candidate transmission links as the target transmission links matching the target information; the target gateway includes the first unicast gateway.

[0114] Among them, the switch deployed on the target transmission link can send target information to the first unicast gateway based on VXLAN.

[0115] S412: When the desired transmission mode of the target information is multicast, determine the candidate transmission links including the first multicast gateway in the determined candidate transmission links as target transmission links matching the target information; the target gateway includes the first multicast gateway.

[0116] S414, when the information transmission protocol used in target information transmission includes a sparse protocol based on protocol-independent multicast, obtain configuration parameters of the uplink port of each switch.

[0117] S416, when the configuration parameter matches the preset parameter corresponding to the sparse protocol, the candidate transmission link where the configuration parameter is located is determined as a candidate transmission link matching the sparse protocol.

[0118] S418: Determine the candidate transmission link that matches the sparse protocol as the target transmission link that matches the target information.

[0119] S420, determining a device gateway corresponding to the target transmission link, and acquiring multicast group information from the device gateway based on the target gateway, and controlling the target transmission link to transmit the target information to a receiving device matching the multicast group information.

[0120] Among them, the specific content of S402-S420 can be adapted to the description of the above content and will not be repeated here.

[0121] Based on the above content, it can be known that the present application can realize the multicast interconnection between the information source and the cloud resource pool based on the SDN cloud controller, and can control the addition and deletion of multicast group members (i.e., receiving devices) in the cloud resource pool. Moreover, since a PIM data dynamic protocol is established between the cloud resource pool and the information source, and the IGMP protocol is used in the cloud resource pool, the interaction between the IGMP protocol and the PIM protocol can be controlled and implemented by the SDN cloud controller, which achieves the purpose of multicast service separation and the purpose of flexibility and control. At the same time, it can avoid the situation where the multicast protocol in the cloud and the multicast protocol of the information source affect each other, such as the addition of multicast group members, the access of multicast sources (such as device gateways, etc.) to the cloud resource pool, etc. The multicast in the cloud and the multicast of the information source can be configured and controlled on the SDN control plane. Moreover, the traditional multicast protocol only supports VLAN multicast, while the present application uses a VXLAN network in the cloud resource pool and supports VXLAN multicast function.

[0122] Moreover, the method provided in this application can be deployed in cloud-based scenarios for securities, stocks, futures, and other brokerage firms. The financial enterprises corresponding to the information source can transmit relevant information to the cloud resource pool through the multicast protocol, and users can access the information on the cloud resource pool through the Internet. This can greatly shorten the cloud migration cycle for brokerage clients, and the dedicated multicast deployment is simple, flexible, and controllable, which has greatly promoted the development of financial-related businesses.
