Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numbers generally refer to like parts or elements.
Fig. 1 shows a schematic diagram of a message transmission system 100 according to an exemplary embodiment of the present invention. As shown in fig. 1, the message transmission system 100 is communicatively connected to the clients 111 to 113, and the connection manner between the message transmission system 100 and the clients shown in fig. 1 is only an example, and the number of clients connected to the message transmission system 100 is not limited by the present invention.
The message transmission system 100 includes a routing server 140 and a management server 130, a push server 160 and a data server 150 connected to the routing server 140. The communication servers 121 to 122 are also connected to the management server 130 through the push server 160. A plurality of communication servers may be deployed in the message transmission system 100, and the number of communication servers deployed in the message transmission system 100 is not limited by the present invention. Communication servers 121-122 may be implemented as SocketServer servers. The communication server, the push server 160, the routing server 140 and the data server 150 in the invention all support horizontal expansion, the push server 160 can be deployed as a push server cluster, the routing server 140 can be deployed as a routing server cluster, and the data server 150 can be deployed as a data server cluster, so as to meet the requirement that the message transmission system 100 sends message files to client lists in a large batch.
The management server 130 is implemented as a Zookeeper management server that manages the communication servers 121 and 122 connected to the push server 160. The communication connection established between the management server 130 and the push server 160 supports various communication protocols, including http, tcp, amqp, etc., and the present invention does not limit the type of the communication protocol used for the communication connection. The communication servers 121 and 122 are registered in the management server 130, and the push server 160 establishes a communication connection with the communication servers 121 and 122. The push server 160 and the communication servers 121 and 122 may establish a TCP connection as a kind of communication connection. The management server 130 generates a list of communication servers that establish a communication connection with the push server 160. When a new communication server comes online in the message transmission system 100, the management server 130 registers the newly-online communication server. When a communication server of the connected push server 160 is offline in the message transmission system 100, the management server 130 deletes the communication server from the communication server list.
Clients 111-113 send communication requests to routing server 140 when needed to establish a communication connection with message transmission system 100 in order to retrieve message files therefrom. According to one embodiment of the present invention, when users of clients 111-113 are watching a live broadcast, a communication connection needs to be established with messaging system 100 in common. The message file sent by the management server 130 to the clients 111 to 113 is a video file at this time, and the clients 111 to 113 receive the message file to present live content.
The routing server 140 may be implemented as a RouterServer server. Upon receiving the communication requests from the clients 111 to 113, the routing server 140 acquires the communication server list from the management server 130 and transmits the communication server list to the clients 111 to 113. The clients 111-113 may select one of the communication servers in the list of communication servers to establish a communication connection. The clients 111 to 113 select the communication servers 121 and 122 in accordance with a certain connection rule including a priority selection of a communication server geographically closest to the client, a priority selection of a communication server having the highest transmission speed with the communication server, and the like. After one communication server is selected by the clients 111 to 113, the selected communication server is transmitted to the routing server 140.
The routing server 140 receives a communication server selected by the client from the communication server list. The selected communication server establishes a communication connection with the clients 111 to 113. The communication servers 121 and 122 and the clients 111-113 only need to establish communication connection once, and long-time data transmission function can be completed until the communication servers are off-line or the clients 111-113 actively disconnect the communication connections with the communication servers 121 and 122. The routing server 140 constructs connection information for the clients 111 to 113 and the unification server that establish communication connection, and stores the connection information in the data server 150. The data server 150 may be implemented as a Redis cache server. The data server 150 stores the connection information of all communication servers in communication connection with the clients 111-113, so as to facilitate the subsequent inquiry of which communication server the clients 111-113 are connected to.
When the management server 130 needs to push a message file to the clients 111 to 113, the management server 130 transmits the message file to be pushed and the clients 111 to 113 that accept the message file to the push server 160. The message files correspond one-to-one to the clients 111 to 113 that receive the message files. The push server 160 may be implemented as a PushServer server. The push server 160 specifies a communication server to which the target clients 111 to 113 are connected, by the connection information stored in the data server 150, and transmits the message file to the clients 111 to 113 via the communication server. When the push server 160 determines the communication servers to which the target clients 111 to 113 are connected, the routing server 140 queries the data server 150 for connection information of the target clients 111 to 113, and determines the communication servers to which the target clients are connected based on the connection information. The routing server 140 accurately queries the data server 150 linked to the target clients 111-113, so that the push server 160 can be prevented from pushing the message file to all the communication servers 121 and 122 in a message broadcasting manner, and the message file can be efficiently pushed to the target clients 111-113.
The clients 111-113, the routing server 140, the management server 130, the communication servers 121 and 122, the push server 160, and the data server 150 in the present invention may all be implemented as one type of computing device. FIG. 2 illustrates a block diagram of a computing device 200, according to an exemplary embodiment of the invention. As shown in FIG. 2, in a basic configuration 202, computing device 200 typically includes system memory 206 and one or more processors 204. A memory bus 208 may be used for communication between the processor 204 and the system memory 206.
Depending on the desired configuration, the processor 204 may be any type of processing, including but not limited to: a microprocessor (μ P), a microcontroller (μ C), a digital information processor (DSP), or any combination thereof. The processor 204 may include one or more levels of cache, such as a level one cache 210 and a level two cache 212, a processor core 214, and registers 216. Example processor core 214 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 218 may be used with the processor 204, or in some implementations the memory controller 218 may be an internal part of the processor 204.
Depending on the desired configuration, system memory 206 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 206 may include an operating system 220, one or more programs 222, and program data 224. In some embodiments, the program 222 may be arranged to execute the instructions 223 of the method 300 according to the invention on an operating system by one or more processors 204 using the program data 224.
Computing device 200 may also include a storage interface bus 234. The storage interface bus 234 enables communication from the storage devices 232 (e.g., removable storage 236 and non-removable storage 238) to the basic configuration 202 via the bus/interface controller 230. At least a portion of the operating system 220, applications 222, and data 224 may be stored on removable storage 236 and/or non-removable storage 238, and loaded into system memory 206 via storage interface bus 234 and executed by the one or more processors 204 when the computing device 200 is powered on or the applications 222 are to be executed.
Computing device 200 may also include an interface bus 240 that facilitates communication from various interface devices (e.g., output devices 242, peripheral interfaces 244, and communication devices 246) to the basic configuration 202 via the bus/interface controller 230. The example output device 242 includes a graphics processing unit 248 and an audio processing unit 250. They may be configured to facilitate communication with various external devices, such as a display or speakers, via one or more a/V ports 252. Example peripheral interfaces 244 can include a serial interface controller 254 and a parallel interface controller 256, which can be configured to facilitate communications with external devices such as input devices (e.g., keyboard, mouse, pen, voice input device, touch input device) or other peripherals (e.g., printer, scanner, etc.) via one or more I/O ports 258. An example communication device 246 may include a network controller 260, which may be arranged to communicate with one or more other computing devices 262 over a network communication link via one or more communication ports 264.
A network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, in a modulated data signal, such as a carrier wave or other transport mechanism, and may include any information delivery media. A "modulated data signal" may be a signal that has one or more of its data set or its changes made in such a manner as to encode information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or private-wired network, and various wireless media such as acoustic, radio Frequency (RF), microwave, infrared (IR), or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
In a computing device 200 according to the present invention, the application 222 includes a plurality of program instructions that implement the message transmission method 300, which may instruct the processor 204 to perform some of the steps of the message transmission method 300 that are run in the computing device 200 of the present invention, such that some of the components in the computing device 200 implement the message transmission by performing the message transmission method 300 of the present invention.

May be implemented as a personal computer including both desktop and notebook computer configurations, and in some embodiments, computing device 200 is configured to perform message transmission method 300.
Fig. 3 shows a flow diagram of a message transmission method 300 according to an exemplary embodiment of the invention. The method 300 is suitable for execution in the computing device 200. As shown in fig. 3, the message transmission method 300 starts at step S310, and after receiving the communication request from the clients 111-113, the routing server 140 obtains the communication server list from the management server 130 and sends the communication server list to the clients 111-113.
The communication server list is generated by the management server 130. In the message transmission system 100, the communication servers 121 and 122 are required to be registered in the management server 130 for formal online operation, and a procedure for registering the communication servers 121 and 122 will be described below. Upon registration of the communication servers 121 and 122 in the management server 130, a communication connection of the push server 160 with one or more communication servers is established, and next a communication server list of communication connections with the push server 160 is generated in the management server 130, so that the clients 111 to 113 select a communication server to be connected therefrom. The communication servers 121 and 122 have to write configuration information of the communication servers 121 and 122 in the management server 130, including: identification ID, ip address, server port, registration time and expansion information.
According to an embodiment of the present invention, when the communication servers 121 and 122 are registered in the management server 130, a communication connection between the communication servers 121 and 122 and the push server 160 is first established. Taking the communication server 121 as an example, the following information is recorded in the management server 130:
ServerId (identification ID): 121, type: string;
serverp (ip address): 192.168.1.8, type: string;
prot (server port): 12, type: int;
registtertime (registration time): 2020.10.26, type: string;
extra (extension information): 0; type (2): concurrentHashMap < String, string >;
similarly, the above information of the communication server 122 is recorded in the management server 130. Subsequently, the management server 130 generates a communication server list including the communication servers 121 and 122 according to the configuration information of the communication servers 121 and 122.
When receiving a communication request from any one of the clients 111 to 113, the routing server 140 transmits the communication server list generated in the above-described step to the clients 111 to 113 that have transmitted the communication request. After receiving the communication server list, the clients 111 to 113 select one of the communication server list to establish a communication link.
Subsequently, step S320 is executed, and the routing server 140 receives one communication server selected by the clients 111 to 113 from the communication server list. Next, step S330 is executed to establish communication connection between the selected communication server and the clients 111 to 113. According to an embodiment of the present invention, client 111 and 112 select to establish a communication connection with communication server 121, and client 113 selects to establish a communication connection with communication server 122, then client 111 and 112 send the selected communication server 121 to routing server 140, and client 113 sends the selected communication server 122 to routing server 140. After receiving the above information, routing server 140 establishes communication connection between communication server 121 and clients 111 and 112, and communication server 122 establishes communication connection with client 113.
After the selected communication server establishes communication connection with the clients 111 to 113, the routing server 140 constructs connection information according to the identifiers of the clients 111 to 113 and the communication server, and the routing server 140 stores the connection information between the clients 111 to 113 and the communication server in the data server 150. The connection information includes the identification id of the clients 111 to 113 and the identification id of the server, and is stored in the data server 150 in the form of key value pairs. The id of the client 111-113 in the connection information is also matched with the client socket id and the connection source of the client. The connection source is the network route from which the clients 111-113 obtain the message document, i.e., from which web page the message document is obtained. The client socket Id is the socket instance identification number of the clients 111-113. The identification id of the server, the socket id of the client and the connection source of the client together form connection information with the identification id of the client. According to one embodiment of the present invention, the structure of the connection information includes:
field: userId (user ID), type: string;
value: object, type: the ONlineClientInfo.
Wherein the ONlineClientInfo comprises:
server ID (server ID), type: string;
clientSid (client socketId), type: string;
source (connection source), type: string;
according to an embodiment of the present invention, after the client 111 establishes a communication connection with the communication server 121, the connection information stored in the data server 150 by the client 111 and the communication server 121 is as follows:
field: userId (user ID): 111, type: string;
object, type: the ONlineClientInfo.
Wherein, the ONLineClientInfo comprises:
server Id (Server ID): 121, type: string;
clientSid (client socketId): 23, type: string;
source (connection source): www.dubai.com, type: string;
subsequently, step S340 is executed, and the management server 130 sends the message file and the target client corresponding to the message file to the push server 160. When the management server 130 wants to send the message files to the clients 111 to 113, it first sends the message files to the push server 160, together with the target clients that receive the message files, where one message file corresponds to each target client. The message file to be transmitted by the management server 130 is not limited to be stored in the management server 130, and the management server 130 may be connected to another content server to acquire the message file from the content server and distribute the message file.
Finally, step S350 is executed, in which the push server 160 determines the communication server to which the target client is connected, and transmits the message file to the clients 111 to 113 via the communication server. When the push server 160 determines the communication server to which the target client is connected, firstly, the push server 160 determines the identifier of the target client, and secondly, the routing server 140 obtains the connection information of the target client from the data server 150 according to the identifier of the target client. Finally, the push server 160 analyzes the connection information to obtain the communication server connected to the target client.
According to an embodiment of the present invention, the management server 130 sends the message file to the client 111, and then sends the message file and the client 111 to the push server 160. The push server 160 determines that the target client identification of the message file is 111. The routing server 140 obtains the connection information of the target client from the data server 150 according to the identifier 111 as follows:
field: userId (user ID): 111, type: string;
value: object, type: the ONlineClientInfo.
Wherein, the ONLineClientInfo comprises:
server Id (Server ID): 121, type: string;
clientSid (client socketId): 23, type: string;
source (connection source): www.dubai.com, type: string;
the routing server 140 obtains the communication server to which the target client is connected as the communication server 121 according to the connection information. The message file is delivered to the client 111 by the communication server 121.
According to an embodiment of the present invention, when a communication server in the message transmission system 100 is offline, the communication server may need to go online due to business expansion, or the communication servers 121 and 122 may fail to provide services continuously due to failure. Thus, the routing server 140 monitors the communication server list of the management server 130. The routing server 140 acquires a communication server list at a predetermined frequency from the management server 130. The predetermined frequency may be set according to the calculation requirements, may be set to obtain every day, or may be set to obtain every day of the month, etc. The routing server 140 determines whether the communication server list transmits a change after receiving the communication server list, and transmits the changed communication server list to the clients 111 to 113 if the communication server list transmits a change, so that the clients 111 to 113 reselect a communication server to be connected. When the communication servers 121 and 122 in the message transmission system 100 go offline, the management server 130 deletes the communication server that is offline from the communication server list, generating a new communication server list. The clients 111-113 originally connected with the offline communication server can select other communication servers from the new communication server list to establish communication connection and acquire the message file.
The message transmission method is suitable for being executed in a message transmission system, the routing server sends a list of communication servers connected with the management server to the client when the client needs to be in communication connection with the system, and the client can select one communication server in the list to be connected. When the management server needs to send the message file to the client, the push server in communication connection with the management server determines which communication server the client is connected to, and directly sends the message file to the client through the communication server, so that the message file can be quickly sent to a target client, and the speed of the client for obtaining the file from the management server is improved.
