Description
Technical Field
The present invention relates to the field of shared computing technologies, and in particular, to a distributed node signaling transmission method and system, a shared computing node, and a signaling gateway.
Background
At present, intelligent equipment is rapidly developed, the number of the intelligent equipment is rapidly increased, and sharing calculation based on the intelligent equipment is also rapidly developed. A core technology of the shared computing is how to quickly and efficiently interact with intelligent equipment, issue commands and collect states. The intelligent device serves as a distributed node, and the technology is equivalent to how the distributed node performs efficient signaling transmission. The existing signaling transmission method is mainly that an application program on a distributed node periodically initiates a request to a server end to inquire whether a command needs to be executed. However, this method has two problems as follows:
(1) since the issuing of the command is a relatively low frequency operation, the return result of most of the requests initiated by the application program is null, i.e. no further operation is required. Furthermore, a plurality of applications are generally run on the distributed node, and each application requires signaling transmission, so a large number of useless requests can be initiated on a single node. This approach can be a significant waste of computing resources of the server.
(2) Because the network conditions of the distributed nodes are various and complex, the request can be initiated only by the distributed nodes, and cannot be initiated by the server, so that the distributed nodes are not flexible.

First embodiment
Referring to fig. 1, a first embodiment of the present invention provides a distributed node signaling transmission system.
In this embodiment, the distributed node signaling transmission system 1 includes a shared computing node 2, a signaling gateway 4, and a shared computing server 6.
The shared computing node 2 is an intelligent device, can contribute to storage, bandwidth and CPU resources, and undertakes computing tasks. The shared computing node 2 includes a local signaling proxy 20 and a plurality of applications 22. The local signaling proxy 20 is used to maintain a long connection with the signaling channel between the access server 40 in the signaling gateway 4. The application program 22 is a computing program running on the distributed shared computing node 2 for performing shared computing tasks using storage, bandwidth and CPU resources on the shared computing node 2. All applications 22 on each shared computing node 2 are collectively signaled by and receive signaling from the signaling channels described above. Because the signaling channel is long-connected, any signaling can be sent out immediately, reducing delay.
The signaling channel is a long-connection bidirectional signaling transmission channel established between the access server 40 and the local signaling proxy 20 based on a Remote Procedure Call (RPC) Protocol and a HyperText Transfer Protocol (HTTP). The local signaling proxy 20 is a client of the signaling channel and the access server 40 is a server of the signaling channel.
The signalling gateway 4 comprises an access server 40 and a signalling server 42. The access server 40 is configured to maintain a long connection with the signaling channel between the local signaling proxy 20, perform authentication and filtering when receiving the signaling of the shared computing node 2, transfer effective signaling to the signaling server 42, and send the signaling to the corresponding shared computing node 2 by using the signaling channel when receiving the signaling from the shared computing server 6 forwarded by the signaling server 42. The signaling server 42 is configured to receive the signaling from the access server 40 from the shared computing node 2, forward the signaling to the shared computing server 6, receive the signaling from the shared computing server 6, quickly locate the access server 40 to which the corresponding shared computing node 2 belongs, and forward the signaling through the access server 40.
The shared computing server 6 is a server side of the shared computing service, and is configured to send a signaling to the corresponding shared computing node 2 through the signaling server 42 and the signaling channel, and receive the signaling sent from the shared computing node 2 at the same time.
Further, the distributed node signaling transmission system 1 further includes a shared computation manager 8, configured to distribute shared computation tasks and maintain task states. The shared computation manager 8 includes a task manager 80 and a task state manager 82. The task manager 80 is used to distribute shared computing tasks to the shared computing nodes 2 via the signaling server 42 and the signaling channels described above. The task state manager 82 is configured to receive a task report from the shared computing node 2 from the signaling server 42, and maintain a task state.
The signaling server 42 is further configured to receive the shared computing task pushed by the task manager 80, quickly locate the access server 40 to which the corresponding shared computing node 2 belongs, and forward the task to the access server 40. The access server 40 is further configured to, after receiving the task forwarded by the signaling server 42, send the task to the corresponding shared computing node 2 by using the signaling channel.
The local signaling proxy 20 on the shared computing node 2 is also used to forward the task received from the signaling channel to the application 22. The application 22 is also configured to execute the received shared computing task and report the task status.
The access server 40 is further configured to receive the task status reported by the shared computing node 2 from the signaling channel, and transmit the task status to the signaling server 42.
The signaling server 42 is further configured to report the task status to the task status manager 82 after receiving the task status from the access server 40.
In addition, the access server 40 is further configured to report node status information to the signaling server 42 when the corresponding shared computing node 2 is on-line, off-line, and overtime. The signaling server 42 is further configured to maintain the node status of each shared computing node 2 according to the node status information reported by the access server 40.
It should be noted that in the distributed node signaling transmission system 1, there may be multiple access servers 40 deployed across regions, so that the signaling channel may implement single-point disaster recovery and cross-machine-room disaster recovery. The single-point disaster recovery means that when an access server 40 to which the shared computing node 2 is connected is abnormal, the shared computing node 2 can be immediately reconnected to the normal access server 40. The cross-room disaster tolerance means that each shared computing node 2 of each room uses an independent domain name when being connected with the access server 40, and the access server 40 finds the abnormal room through domain name polling and quickly connects to the shared computing node 2 of the normal room.
In addition, each shared computing node 2 may establish a plurality of the above signaling channels with a plurality of access servers 40 at the same time, monitor the quality of all the signaling channels, and immediately start a new signaling channel when it is checked that the current signaling channel is unstable. Or, the shared computing node 2 uses the signaling channel with the best quality to transmit the signaling according to the quality priority of each monitored signaling channel when sending the signaling each time.
