Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations (or steps) can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1 is a flow chart of a device connection processing method under a hybrid network according to an embodiment of the present invention. The technical scheme of the embodiment can be applied to the situation that equipment connection is carried out on the client and the response end under the hybrid network. As shown in fig. 1, the method for processing device connection under the hybrid network in the embodiment of the application may include the following steps:
s110, splitting an initial transmission link between the client and the response end into a code stream transmission link and a signaling transmission link.
Referring to fig. 2, a networking mode of a public network internet of things device is described, after an account is registered on an internet of things cloud service platform, a plurality of response end devices (such as internet of things monitoring devices) are accessed to the cloud service platform in a local area network through a router, and the response end devices are added under the account. After the client application logs in the cloud service platform account, the responding end equipment under the account can be checked, and the service operation is performed.
Referring to fig. 2, the cloud service platform may include a plurality of functional components such as a service server, a forwarding server, and a P2P server, where the forwarding server mainly provides a relay forwarding function, and when a client and a responding device cannot be directly connected or need relay forwarding, network link resources are allocated to the client and the responding device to implement connection; and the response end equipment sends the code stream signaling to the forwarding server, and the forwarding server forwards the code stream signaling to the client. The link established by the responding device and the client through the forwarding server is in a one-to-one relationship. The P2P server mainly provides a P2P tunnel connection function, and after the client acquires the P2P server connection information and the device connection information through the scheduling server, a tunnel is established between the client and the responding device through the P2P server, so that end-to-end connection is realized.
The client may also be referred to as a user end, and may also refer to an application program corresponding to a server, which provides local services for the client. For example, in a real-time streaming media forwarding, a client connects to a forwarding server, and enters a playing page to send a playing request according to a playing requirement of a user. Clients include, but are not limited to, APP, applet, web browser, etc.
The response end can refer to a reply to the request sent by the client, the client sends out the request according to the client requirement, and the response end sends out a corresponding response according to the requirement after receiving the request. For example, the client sends a play request according to the client requirement, and the response end forwards the play request to the play port for playing after receiving the play request.
Referring to fig. 2, when a client initiates a connection access service to a responding device through a cloud service, a cloud service platform service server returns network information required for establishing a forwarding or P2P tunnel connection with the responding device to the client. After receiving the information, the client initiates forwarding connection and/or P2P tunnel connection to the responding end equipment through the forwarding server and the P2P server. Alternatively, the established connection may comprise a tunnel connection and a forwarding connection, which may be implemented via TCP and UDP, respectively.
Referring to fig. 3, when a client establishes a connection service with a responder device, support of a client connection service C placed at the client and a responder connection service S placed at the responder device is generally required. Taking the example of establishing forwarding connection, after receiving network information (such as a connection port S1) required for establishing connection with a response end device sent by a cloud service platform, a client service layer establishes connection with a signaling port X1 of a client connection service C; the client connection service C establishes connection with a connection port S1 in a response end connection service C in a response end connection service S through a connection port C1 in the client connection service C, and the response end connection service S establishes connection with a signaling port X2 returned by a response end device business layer in a callback function in advance. The connection service establishment between the client and the responding device is completed.
Referring to fig. 3, after the connection between the client and the response end device is established successfully, when the client needs to perform the code stream service, the connection between the client and the client connection service C is established through the code stream port M1. The response end connection service S establishes connection with the response end equipment through the code stream port M2, an initial transmission link between the client end and the response end can be formed at the moment, and two ends of the initial transmission link are respectively bound with the client end code stream port M1 and the signaling port and the response end code stream port M2 and the signaling port. In this way, the response end device sends the coded video frequency code stream data through the code stream port M2, and the data forms a format suitable for transmission in a tunnel or a forwarding connection link through the response end connection service S. After data is transmitted to a connection port C1 of the client through a network, the client connection service C converts the data format, the video code stream data is divided into packets and then is transmitted to a service layer of the client through a code stream port M1 of the client, the service layer is displayed on an interface after being decoded and displayed, and the code stream data is transmitted between the client and a response end through an initial transmission link.
Referring to fig. 3, the connection between the client and the responding device is split between the signaling port and the code stream port, but the final transmission is converged on one transmission link. When the network fluctuates, video jamming or signaling accumulation can obviously occur; when serious, the client sends control signaling to the responding terminal equipment or the responding terminal equipment actively reports the service alarm information, and the information is accumulated in the connecting channel to wait for processing, so that the key signaling cannot take effect or the key alarm information cannot be reported in time, thereby reducing the service availability.
Referring to fig. 4, in order to solve the problem of the scheme in fig. 3, an initial transmission link between a client and a responding device may be split into a code stream transmission link and a signaling transmission link respectively established between the client and the responding device. Fig. 3 shows that both ends of an initial transmission link formed by the establishment of the client connection service C and the response connection service S bind the client code stream port and the signaling port, and bind the response code stream port and the signaling port, respectively. However, referring to fig. 4, after the initial transmission link is split into the code stream transmission link and the signaling transmission link, two ends of the signaling transmission link are respectively connected with the signaling port X1 of the client and the signaling port X2 of the response end in a binding manner, and two ends of the code stream transmission link are no longer connected with the signaling port X1 of the client and the signaling port X2 of the response end in a binding manner, but are only connected with the code stream port M1 of the client and the code stream port M2 of the response end in a binding manner. The code stream transmission link generated by splitting the initial transmission link may include one or at least two, and the signaling transmission link generated by splitting the initial transmission link may include one or at least two.
Signaling interaction between the client and the responding terminal equipment or signaling report such as an alarm event of the responding terminal equipment are transmitted through a signaling transmission link (as a dashed line box in fig. 4); particularly, some key signaling, such as reporting of a message of a key event or keep-alive heartbeat of equipment, can cause the condition that the equipment is disconnected, alarm message is missed and the like to influence service availability if the key signaling cannot be timely transmitted.
S120, the code stream transmission link is adopted to transmit the code stream data between the client and the response end.
The code stream may refer to the number of times that the communication port changes in level when transmitting data in 2 seconds, also called the code rate, and the more data is transmitted in unit time, the more information is contained. For example, a video stream with a large message size may be used.
S130, signaling interactive transmission is carried out between the client and the response end by adopting a signaling transmission link.
The signaling may refer to various signals transmitted by the network, some of which are not directly needed by the user and are used for specially controlling the circuit, and the signals are called signaling, and may refer to a request of a small-message-amount control message. The transmission of signaling requires transmission between different links of the communication network, including, but not limited to, base stations, mobile stations, and mobile control switching centers, etc.
The embodiment of the invention discloses a device connection processing method under a hybrid network, which splits an initial transmission link between a client and a response end according to a service model and a network condition, and respectively establishes a signaling transmission link and a code stream transmission link, wherein the establishment of the two links can flexibly adopt tunnel connection and forwarding connection according to service requirements and is established through TCP or UDP; a code stream transmission link is adopted to transmit code stream data between a client and a response end; and signaling interactive transmission is carried out between the client and the response end by adopting a signaling transmission link. The transmission of the key signaling is separated from the transmission of the video code stream data, so that the technical effect of avoiding influencing the transmission of the key signaling due to overlarge code stream data quantity is realized.

Of course, the client backup connection port in the client connection service is not limited to one client backup connection port in fig. 4, and may include at least two client backup connection ports, and likewise the response backup connection port in the response connection service is not limited to one response backup connection port in fig. 4, and may include at least two response backup connection ports, so that it is convenient to establish and generate multiple transmission links, and is not limited to one signaling transmission link and one barcode streaming transmission link.
S220, connecting the client spare connection port with the response end spare connection port, and respectively binding the client signaling port and the response end signaling port at the two ends of the connection to obtain a signaling transmission link.

The transmission of the code stream data may refer to outputting from a client primary code stream port M1 in the client connection service, transmitting the data to a connection port C1 through a message conversion unit CT, connecting the client connection port C1 with a connection port S1 of a response end device, and transmitting the code stream data to a code stream port M2 through the message conversion unit ST, thereby implementing code stream data transmission between the client and the response end by using a code stream transmission link.
The client code stream port and the response end code stream port in the code stream transmission link are connected through a tunnel, and are transmitted through a UDP protocol, so that the network resource consumption of the cloud server is reduced, and the connection success rate and the stability are improved.
S250, signaling interactive transmission is carried out between the client and the response end by adopting a signaling transmission link.
The signaling interactive transmission may be that the signaling is output from a main signaling port X1 of the client in the client connection service, the signaling is transmitted to a connection port C2 through a message conversion unit CT, the connection port C2 of the client is connected to a connection port S2 of the response end device, and the signaling is transmitted to the signaling port X2 through a message conversion unit ST, so that the signaling interactive transmission between the client and the response end is implemented by using a signaling transmission link.

Embodiments of the present invention may be further optimized on the basis of the foregoing embodiments, and may be combined with each of the alternatives of one or more of the foregoing embodiments. As shown in fig. 6, the method for processing device connection under a hybrid network according to the embodiment of the present invention may include the following steps:
and S310, after the client and the response end communicate through an initial transmission link, periodically detecting resource state information between the client and the response end.
Wherein, in the connection service C, a dispatching unit CD and a resource detecting unit CR are added; and in the connection service S, a scheduling unit SD and a resource detection unit SR are added. As depicted by the dashed lines in fig. 7, the resource detecting unit detects resource information of the client and the responding device, including network delay and congestion conditions, system resource consumption conditions, and the like. The scheduling unit is used for scheduling and establishing new connection according to the information fed back by the resource detection unit and combining with a preset strategy, and binding the related unit with the new connection.

After receiving the resource detection packet, the resource detection unit pre-configured in the response end connection service sends a detection packet reply message to the resource detection unit pre-configured in the client connection service; the probe packet reply message includes, but is not limited to, a probe packet identifier and a standby connection port of a response end in the response end connection service;
and the resource detection unit preconfigured in the client connection service determines resource state information between the client and the response end according to the packet receiving and transmitting conditions of the same detection packet.
And S320, if the resource state information is detected to find out that the resource is abnormal, enabling a client standby connection port in the client connection service and a response standby connection port in the response connection service to obtain a code stream transmission link and a signaling transmission link.
After the connection between the client and the responding device is established, the resource detection unit CR communicates with the resource detection unit SR through the connection port C1. After the first-test communication is completed, the resource detection unit CR and the resource unit S detect a plurality of parameters such as system cache, network delay, congestion, and the like. When detecting that an abnormality is found, the resource detecting unit CR transmits a message of the abnormality of the resource to the resource detecting unit SR.

when the network delay of the detection packet of the resource detection unit CR exceeds a preset threshold (assumed to be 1S), the network delay in the connection C1-S1 is considered to be larger, and an abnormal state is reached. The resource detection unit CR sends a message of resource abnormality to the resource detection unit SR;
the resource detection unit CR reports a message of resource abnormality to the dispatching unit CD, wherein the message contains information such as the type of the resource abnormality and a reserved connection port S2 of the connection service S;
the scheduling unit CD judges according to the type of resource abnormality, the current abnormality is that network congestion causes larger delay, and in order to ensure key signaling delivery and key information reporting, the message conversion unit CT is informed to monitor the reserved connection port C2 at the same time; notifying the resource detecting unit CR to detect the connection port C2;
meanwhile, the scheduling unit SD of the connection service S notifies the message conversion unit ST to monitor the connection port S2 at the same time according to the type of the resource abnormality. Notifying the resource detection unit SR to detect the connection port S2;
The connection service C establishes a connection to the connection port S2 of the connection service S through the connection port C2.
From this point on, the client establishes a new connection C2-S2 with the responding device, which may be connected differently than C1-S1. For example, C1-S1 may employ a tunnel connection, transported via UDP protocol; the C2-S2 may employ a forwarding connection for transmission over the TCP protocol. The resources are not occupied mutually, and the key signaling of C2-S2 and the network access for reporting the key information are ensured.
Optionally, the scheduling unit adopts different strategies according to different types of resource exceptions. The embodiment also provides a connection mode under the conditions that the message conversion unit has performance bottleneck and the network delay is larger. As shown in fig. 9: the scheduling unit CD combines a preset policy according to the anomaly type, and when a new connection is established, adds a message conversion unit CT2, and notifies the message conversion unit CT2 to monitor the connection port C2 and bind with the signaling port X1. Meanwhile, the notification message converting unit CT is unbinding from the signaling port X1. The resource detecting unit CR detects the connection ports C1 and C2 at the same time.
The scheduling unit SD combines the preset policy according to the anomaly type, and when a new connection is established, adds the message conversion unit ST2, and notifies the message conversion unit ST2 to monitor the connection port S2 and bind with the signaling port X2. The notification, notification message conversion unit ST unbundles with signaling port X. The resource detection unit SR detects the connection ports S1 and S2 at the same time.
S330, when the resource state information is detected and the abnormal recovery of the resource is found, reverse merging recovery is carried out from the code stream transmission link and the signaling transmission link to the initial transmission link according to the type of the abnormal recovery of the resource.
With the processing of the service and the change of the network condition, the system resource consumption of the connection C1-S1 between the client and the responding terminal equipment can change. When the system resource changes, the resource detecting unit CR reports the abnormal recovery information to the dispatching unit CD according to the real-time detection condition and combining with the preset threshold value, and simultaneously informs the resource detecting unit SR.
After receiving the abnormal recovery message of the resource detection unit CR, the scheduling unit CD performs reverse operation during connection splitting according to the type of resource recovery, and adaptively merges the connections.
For example, the connection splitting condition (as shown in fig. 9) when the message conversion unit has a performance bottleneck and the network delay is large is restored to the connection condition (as shown in fig. 7) that the message conversion unit has normal performance and the network delay is normal. The operation steps are as follows: the resource detection unit SR reports the abnormal type to the scheduling unit SD; the dispatching unit SD informs the message conversion unit ST to be bound with the signaling port X2; the scheduling unit SD clears the message conversion unit ST2 and recovers resources; the connection service C disconnects the connection port C2 from the connection port S2; the dispatching unit CD informs the message conversion unit CT to bind with the signaling port X1; the scheduling unit CD retrieves the message converting unit CT2 and retrieves the resources.
The embodiment of the invention discloses a device connection processing method under a hybrid network, which is characterized by periodically detecting resource state information between a client and a response end; when detecting the resource state information and finding out that the resource is abnormal, starting a client standby connection port in the client connection service and a response standby connection port in the response connection service to obtain a code stream transmission link and a signaling transmission link. The method solves the problem that the message conversion unit has performance bottleneck and larger network delay, ensures the network path for reporting key signaling and key information, realizes the connection between the self-adaptive adjustment application and the equipment, saves network resources and improves the usability of a service system.
