Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The scheme of the embodiment of the invention is suitable for a communication system, and the communication system comprises at least two network nodes: the system comprises at least one client and at least one server, wherein the at least one client comprises a first client; the first client acquires a first message to be sent to the server, sends the first message to at least one network node except the first client in the at least two network nodes, and the first message is relayed in the at least two network nodes until the first server in the at least one server stops the relay transmission of the first message in the at least two network nodes when receiving the first message. The relay transmission means that the network node receives the first message and forwards the first message. Because the message is transmitted among the network nodes in a manner similar to diffusion, the message can not be loaded to the server at the same time, and the server crash caused by the fact that the message is loaded to the server at the same time is avoided.
Referring to fig. 1, fig. 1 is a schematic flow chart of a message transmission method according to an embodiment of the present invention, which is particularly applied to a monitoring system with a C/S architecture, where the monitoring system includes at least two network nodes, where the at least two network nodes include at least one client and at least one server, and the method includes:
s101, a first client acquires a first message to be sent.
In this embodiment, the first client may be any one of the at least one client. Specifically, the manner in which the first client acquires the first message to be sent to the server is as follows:
the first client acquires data which is generated in the first client and needs to be monitored, wherein the data includes but is not limited to user data, optionally, the data acquired by the first client includes but is not limited to video data, audio data and the like, smoke concentration in air, mileage and speed data of a vehicle which is driven in real time and the like, and the first client encapsulates the acquired data into a first message.
And secondly, first messages received by the first client from other network nodes in the monitoring system.
S102: the first client selects at least one network node from the at least two network nodes and sends the first message to the selected at least one network node, wherein the first message is relayed among the at least two network nodes.
In the embodiment of the application, in order to prevent the problem that the server is jammed or crashed because the acquired data is loaded to the server by each client side at the same time, a new message transmission method is adopted. The first client randomly selects at least one node for sending the first message in one propagation period, and in the next propagation period, each node in the at least one node randomly selects at least one node again to relay sending. Optionally, the selection manner of each node in selecting at least one node may be to select a node within a preset range of the node as the at least one node.
Referring to fig. 2, fig. 2 is a schematic diagram of a message transmission method according to an embodiment of the present invention, where the schematic diagram mainly specifically describes relay transmission according to an embodiment of the present invention. Fig. 2 includes 5 network nodes, which is exemplified by taking a node 1 as a first client, where the node 2 acquires a first message, the node 1 selects a node 2 and a node 3, and sends the first message to the node 2 and the node 3, respectively, in a first propagation period, after receiving the first message, the node 2 may select a node 3 and a node 4, and send the first message to the node 3 and the node 4, respectively, in a second propagation period, and similarly, after receiving the first message, the node 3 may select a node 4 and a node 5, and send the first message to the node 4 and the node 5, respectively, in the second propagation period, and so on, the first message is relayed among a plurality of nodes.
S103: stopping the relayed transmission of the first message in the at least two network nodes until the first server of the at least one server receives the first message.
Referring to fig. 3, fig. 3 is a schematic diagram of a message transmission method according to an embodiment of the present invention, in a process of relay transmission of a first message, a client 1 shown in fig. 3 selects a client 2 and a first server to send the first message, where the clients 1 and 2 and the first server in fig. 3 are nodes in fig. 2, and the first server receives the first message, and stops the relay transmission of the first message between the nodes. For example, after receiving the first message, the first server sends a broadcast message to a plurality of network nodes in the monitoring system, where the broadcast message includes a message identifier of the first message, and the broadcast message is used to instruct to stop relaying the first message among the at least two network nodes. After each network node receives the broadcast message, the forwarding of the first message is stopped.
In one implementation, the first client receives a broadcast message from the first server. If the first client receives the first message again, the first client stops forwarding the first message according to the broadcast message, and because the first client can acquire the data generated in the first client and required to be monitored, and package the data into the first message, and can also receive the first message from other network nodes in the monitoring system, the first client can be any one of the at least one client, that is, any one of the at least one client can receive the broadcast message, and if the client receives the broadcast message, the first message is not forwarded any more.
Specifically, in the relay transmission process of the first message in the network node, until the first server receives the first message, the monitoring system may have both a network node that receives the first message and a network node that does not receive the first message, and when the first client receives the broadcast message from the first server, if the first client receives the first message, the forwarding of the first message is stopped according to the broadcast message.
By stopping the relay transmission of the first message in the at least two network nodes after the first message is transmitted to the first server, the unnecessary continuous transmission of the first message in the network nodes is avoided, and meanwhile, the broadcast message carries information with the information quantity far smaller than that of the first message, the broadcast message indicates the stop transmission of the first message, thereby reducing the meaningless resource overhead and reducing the network load.
In an implementation manner, if only one server is included in the at least one server, the server is a first server, and until the first server receives the first message, the relay transmission of the first message in the at least two network nodes is stopped.
In an implementation manner, the at least one server includes a server in a leader role and at least one server in a following role, and the server in the leader role is used for managing the server in the following role; the first server may be the server in the leader role or the server in the follower role.
Specifically, in this possible implementation, different implementation scenarios exist due to the different roles of the first server:
firstly, if the first server is a server with a leader role, because only one server with the leader role exists in at least one server, until the server with the leader role receives a first message, the relay transmission of the first message in the at least two network nodes is stopped, the first client receives a broadcast message from the server with the leader role, the broadcast message carries a message identifier of the first message, and the broadcast message is used for indicating that the relay transmission of the first message in the at least two network nodes is stopped.
Further, if the server in the at least one server receives the broadcast message, the forwarding of the first message is also stopped.
And if the first server is a role following server, stopping relay transmission of the first message in the at least two network nodes until any role following server receives the first message, and receiving a broadcast message from the first server by the first client, wherein the first server is any role following server which receives the first message, the broadcast message carries a message identifier of the first message, and the broadcast message is used for indicating that relay transmission of the first message in the at least two network nodes is stopped.
Further, if the server in the at least one server receives the broadcast message, the forwarding of the first message is also stopped.
If the first server is a server serving as a leader role or a server serving as a follower role, that is, the first server may be any server in the at least one server, that is, after receiving the first message, any server in the system stops the relay transmission of the first message in the at least two network nodes, and the first client receives a broadcast message from the first server, where the broadcast message carries a message identifier of the first message, and the broadcast message is used to indicate that the relay transmission of the first message in the at least two network nodes is stopped.
Through the flexible selection of the three implementation scenes, the purpose that the transmission between the network nodes is stopped after the first message is transmitted to the server can be achieved, the meaningless resource overhead is reduced to a great extent, and the network load is reduced.
Optionally, in an implementation manner, if the first server is the server that serves as the follow-up role, the method further includes:
the first client receives a broadcast message from a second server of the at least one server, wherein the broadcast message includes a message identifier of the first message, the broadcast message is used for instructing to stop relaying the first message in the at least two network nodes, and the second server is the server of the at least one server which is in the leader role. And if the first client receives the first message, the first client stops forwarding the first message according to the broadcast message. That is, after the server of the following role receives the first message, the server of the leader role sends out a broadcast message for instructing to stop relay transmission. The implementation scenario in this embodiment may also be used in combination with the implementation scenario in the previous embodiment, that is, after receiving the first message, any one of the servers stops the relay transmission of the first message in at least two network nodes.
As shown in fig. 4 and referring to fig. 4, fig. 4 is a schematic flowchart of another message transmission method provided in an embodiment of the present invention, which is particularly applied to a monitoring system with a C/S architecture, where the monitoring system includes a plurality of network nodes, and the plurality of network nodes include at least one client and at least one server, and the method includes:
s201 a first server receives a first message relayed transmission among the at least two network nodes.
The first server is a server in the at least one server, the relay transmission refers to that the network node receives the first message and forwards the first message, and with reference to fig. 5, as shown in fig. 5, the number of servers included in the monitoring system is only 1, the server is the first server, and by the relay transmission, the client 1 in fig. 5 sends the first message to the client 3 and the first server, and a specific implementation manner of the relay transmission refers to step S102, which is not described in detail herein.
S202, the first server sends a second message, and the second message is used for triggering the first message to stop relay transmission in the at least two network nodes; wherein the second message comprises a message identification of the first message.
As shown in fig. 5, in a possible implementation manner, a client 1 sends a first message to a client 3 and a first server in the figure, where the first server sends a broadcast message in the monitoring system after receiving the first message, where the broadcast message carries a message identifier of the first message, and the broadcast message is used to instruct to stop relay transmission of the first message in the at least two network nodes. As shown in fig. 5, the first server sends the broadcast message, and in the figure, the client 1 and the client 3 do not forward the first message any more after receiving the broadcast message.
In a possible implementation manner, the at least one server includes a server that serves as a leader role and at least one server that serves as a follower role, and the server that serves as the leader role is used to manage the server that serves as the follower role, and since the first server may be the server that serves as the leader role or the server that serves as the follower role, the following detailed description is made according to different scenarios generated by different roles of the first server:
scene one: if the first server is the server which is used as the leader role, the server which is used as the leader role does not send out the broadcast message until the server which is used as the leader role receives the first message, the relay transmission of the first message in at least two network nodes is stopped, and the server which is used as the leader role of the first server sends the first message to at least one server which is used as the follow role, so that the server which is used as the follow role backups and stores the first message. That is, the server in the role following function is used as a backup of the server in the role leading function, the server in the role leading function is a path for preferentially summarizing messages, and data in the server in the role leading function is earlier than data in the server in the role following function. The operation and maintenance personnel can use the data in the server with the leader role preferentially.
Scene two: if the first server is a server serving as a follow-up role, that is, the first server may be any one of at least one server serving as a follow-up role, that is, after receiving the first message, the server serving as any follow-up role sends a broadcast message to stop relay transmission of the first message in at least two network nodes, and the first server serving as a follow-up role directionally forwards the first message to the server serving as a leader role, so that the server serving as the leader role stores the first message in a backup manner to the at least one server serving as a follow-up role.
Scene three: if the first server is a server serving as a leader role or a server serving as a follow-up role, that is, the first server may be any one of the at least one server, that is, after receiving the first message, any one server in the system sends a broadcast message to stop relay transmission of the first message in the at least two network nodes, and if the server serving as the leader role receives the first message first, the server serving as the follow-up role sends the first message to at least one server serving as the follow-up role, so that the server serving as the follow-up role backs up and stores the first message; if the server of the following role receives the first message first, the server of the following role which receives the first message sends a broadcast message to stop relay transmission of the first message in at least two network nodes, and the first server of the following role directionally forwards the first message to the server of the leader role so that the server of the leader role backups and stores the first message to at least one server of the following role.
In this embodiment, the messages are transmitted in a diffused manner without loading all the messages to the server at the same time, so that the load, network congestion and instantaneous outbreak of high-load operation can be effectively balanced, the monitoring system can accommodate more clients, the capacity of the monitoring system is increased, and the need for premature splitting and deployment of multiple sets of monitoring systems of the same type is avoided.
As can be seen from the above, the server in the leader role serves as a path for preferentially summarizing messages, data in the path is the latest, and if the server in the leader role fails, a new leader role is determined from the at least one server serving as the follower role. The following is a detailed description of the determination process of the leader role:
in the embodiment of the application, when the server of the leader role fails, a new server of the leader role can be automatically elected, so that the continuous availability of the whole system is ensured.
If one server which is taken as a leader role and is included in at least one server in the system does not fail, a heartbeat message is periodically sent to at least one server which is taken as a follow role and is included in at least one server in the system, so that the server which is taken as the leader role does not fail is indicated to the server which is taken as the follow role. Each role-following server has its own clock, and if the role-following server does not receive the heartbeat message of the leader role within a preset time interval of the clock, the role-following server determines that the role-following server fails, switches to a candidate state, and sends voting messages to all other role-following servers to instruct the other role-following servers to vote to the candidate server. If the candidate has acquired most of the votes from all of the role-following servers, the candidate switches to the leader role's server and sends a broadcast message to all of the role-following servers indicating that the role-following servers are the new leader role's server.
In this embodiment, the server with the leader role is used as the server with the latest data, and the operation and maintenance staff preferentially use the data in the server with the leader role, and if there are other monitoring requirements, the operation and maintenance staff can also connect to other servers with the leader role.
Referring to fig. 5, an interaction flowchart of a message transmission method according to an embodiment of the present invention is shown, where as shown in the figure, the embodiment includes, but is not limited to, the following steps:
s301, the first client acquires a first message to be sent. S302, a first client selects at least one network node from at least two network nodes and sends a first message to the selected at least one network node, wherein the first message is relayed in the at least two network nodes. S303, the first server receives a first message relayed transmission among at least two network nodes.
