Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
The resource pool proxy server is a Virtual or physical device in the video Network, which can act as a proxy for the protocol conversion device, similar to a VPN (Virtual Private Network) in the video Network. In the prior art, a resource pool proxy server is usually in communication connection with protocol conversion equipment, and then dynamic virtual terminal number allocation can be performed among the using terminals corresponding to the plurality of protocol conversion equipment, that is, the virtual terminal number is adaptively allocated according to the communication demand of the actual using terminal, so that the problem that resources cannot be efficiently allocated when the protocol conversion equipment is used for allocating the virtual terminal number is solved.
However, in the above technology, the resource pool proxy servers are independent of each other, and the load of each resource pool proxy server is also limited. In practice, sometimes there are cases where one resource pool proxy server subscribes to multiple protocol conversion devices and manages excessive virtual terminal numbers, and the operation speed is slow due to the overload of the virtual terminal numbers, while another resource pool proxy server has a low load and is in an idle state, so that resources cannot be reasonably allocated, and the operation efficiency of the video networking system is low.
In addition, in the prior art, the resource pool proxy server is in communication connection with the core server of the video network, the resource request obtained by the resource pool proxy server is forwarded or transmitted through the core server of the video network, and the resource pool proxy server or the protocol conversion device must also be forwarded through the core server of the video network in order to return the response information or resource data for the resource request to the user, so that the operating pressure of the core server of the video network is too high.
In view of the above problem, referring to fig. 1, a flowchart of a first step of a method for sending request data according to an embodiment of the present invention is shown, where the method is applied to a video network, and the video network is communicatively connected to an ethernet network, where the video network includes a video network core server, a master resource pool proxy server in the ethernet network, a plurality of slave resource pool proxy servers communicatively connected to the master resource pool proxy server, and the video network core server is communicatively connected to the master resource pool proxy server and the plurality of slave resource pool proxy servers respectively; the method may specifically comprise the steps of:
step S101, the master resource pool proxy server receives synchronous data pushed by a plurality of slave resource pool proxy servers based on Ethernet or video network; the synchronization data comprises the current load information of the proxy server of the slave resource pool;
aiming at the technical problem, firstly, the embodiment of the invention carries out cluster deployment on a plurality of resource pool proxy servers, divides the servers in the cluster deployment into a main resource pool proxy server and a subordinate resource pool proxy server, establishes a master-slave structure between the main resource pool proxy server and the plurality of subordinate resource pool proxy servers, and the main resource pool proxy server is the core of the whole cluster. Meanwhile, the communication connection is directly established between the master resource pool proxy server and the slave resource pool proxy server through the Ethernet, so that two transmission paths are arranged between the master resource pool proxy server and the slave resource pool proxy server, namely the transmission path based on the video networking protocol or the transmission path based on the Ethernet protocol, and the operation pressure of the video networking core server can be relieved.
Therefore, the embodiment of the invention can adopt two paths of Ethernet or video network to receive the synchronous data pushed by the resource pool proxy server. Here, synchronizing data may include coordinating the current CPU load, network load, and memory load of the resource pool proxy server. Of course, the co-slave resource pool proxy server also pushes the synchronization data to the master resource pool proxy server based on two different paths of the ethernet or the video network.
As to which path the slave resource pool proxy server selects to push the synchronization data to the master resource pool proxy server, the selection may be made according to different situations, such as:
(1) the cooperative slave resource pool proxy server has a good current network and a low load, can set a timing push thread, does not need manual operation, and pushes synchronous data to the master resource pool proxy server based on the Ethernet at a certain interval so as to actively reflect the current load condition of the cooperative slave resource pool proxy server to the master resource pool proxy server. In the scheme, the video network is not suggested to be adopted to push the synchronous data to the main resource pool proxy server, and the regular push thread is frequently sent, so that excessive video network resources are easily occupied, and the running pressure of the video network is caused.
(2) The cooperative resource pool proxy server can also set a stepped synchronization threshold value for each load (such as CPU load, network load and memory load) of the cooperative resource pool proxy server, and when a certain load reaches the synchronization threshold value of the first stage, data is pushed to the main resource pool proxy server based on Ethernet or video network; after the load reaches the synchronization threshold value of the second stage, synchronous data is pushed to the main resource pool proxy server based on the Ethernet or the video network; certainly, when the total load (the sum of each load such as the CPU load, the network load, and the memory load) reaches a certain threshold, the synchronous data is actively pushed to the primary resource pool proxy server based on the ethernet or the video network.
(3) Of course, the cooperative resource pool proxy server pushes the synchronization data to the master resource pool proxy server, or the synchronization data may be returned according to a synchronization data request sent by the master resource pool proxy server. When a main resource pool proxy server sends a synchronous data request to a subordinate resource pool proxy server based on the video networking, the subordinate resource pool proxy server pushes synchronous data to the main resource pool proxy server based on the video networking; when the master resource pool proxy server sends a synchronous data request to the slave resource pool proxy server based on the Ethernet, the slave resource pool proxy server pushes synchronous data to the master resource pool proxy server based on the Ethernet.
For the implementation of the step S101, the data can be pushed by using the ethernet or the video network, and the data is pushed by using the ethernet, so that the steps of transparent transmission by using the core server of the video network are reduced, and the operation is faster. But based on the characteristics of the video network, synchronous data is pushed based on the video network, so that the method is safer, and a malicious third party can be prevented from acquiring the current load information of the proxy server of the slave resource pool and tampering related data.
In the embodiment of the invention, after the cooperative resource pool proxy server pushes the synchronous data to the main resource pool proxy server, the response data of the main resource pool proxy server does not need to be waited, so that the occupation of the cooperative resource pool proxy server or the video network system resource can be further reduced, and the operating pressure of the cooperative resource pool proxy server or the video network system resource is reduced.
Step S102, the master resource pool proxy server determines a target slave resource pool proxy server from a plurality of slave resource pool proxy servers according to the current load information of the slave resource pool proxy servers;
and a plurality of virtual terminal numbers are registered in the core server of the video network, and the virtual terminal numbers are used as authentication identifiers of the service object data in the video network after generating a binding relationship with the service object data. The resource pool proxy server is mainly used for managing and distributing the change condition of the resource state information of the protocol conversion equipment, and the protocol conversion equipment is used for accessing the monitoring resource in the internet into the video network.
Based on the above, the current load information of the proxy server of the slave resource pool synchronized in the embodiment of the present invention includes the number of virtual terminal numbers in the binding relationship currently stored by the proxy server of the slave resource pool; the number of the virtual terminal numbers reflects the current load occupation condition of the proxy server of the cooperative resource pool, and the larger the number is, the larger the load occupation quantity is; conversely, the smaller the number, the smaller the load occupation, and correspondingly, the more tasks the proxy server of the cooperative resource pool can allocate.
The specific implementation step of step S102 includes:
and the master resource pool proxy server determines a target slave resource pool proxy server from the plurality of slave resource pool proxy servers according to the virtual terminal numbers which are currently managed by the plurality of slave resource pool proxy servers and are in the binding relationship. In this embodiment of the present invention, one of the determined conditions of the target slave resource pool proxy server may be one of the multiple slave resource pool proxy servers, where the number of virtual terminal numbers in the currently managed processing binding relationship is the smallest.
Step S103, the main resource pool proxy server sends request data for acquiring service object data to the target slave resource pool proxy server based on Ethernet or video network.
In the embodiment of the invention, the system also comprises a user terminal which is in communication connection with the main resource pool proxy server; the request data for obtaining the business object data can come from a user terminal or other systems, wherein the system comprises other servers and terminals, the terminals are in communication connection with the other servers, and the other servers are in communication connection with a primary resource pool proxy server based on Ethernet or video network. For example, the other terminal may be a streaming server, and the terminal may be a mobile phone.
Preferably, the step S103 may specifically include the following sub-steps:
substep 1, the main resource pool proxy server receives request data for acquiring service object data sent by the user terminal based on Ethernet or video network;
in the embodiment of the present invention, the user terminal may be an integrated intelligent device with a camera, and the intelligent device may include, but is not limited to, a video network terminal and a kiosk. The user terminal can be configured with an android system and comprises a network interface module, a service processing module and a CPU module which are described in the following content 1.2 of the introduction part of the video networking, wherein the network interface module can be configured with a video networking network card, and the video networking network card is used for accessing the video networking through a video networking core server and receiving or sending data based on a video networking protocol through the video networking. Therefore, the main resource pool proxy server can receive request data sent by the user terminal based on the video networking.
In view of the technical problems of the present invention, the user terminal according to the embodiment of the present invention may further directly communicate with the primary resource pool proxy server based on the ethernet, and send request data to the primary resource pool proxy server through the ethernet, thereby further reducing the occupation of the video networking system and reducing the operating pressure of the video networking core server.
The transmission path through which the user terminal sends the request data to the main resource pool proxy server can be determined according to the operating pressure of the video networking system (video networking core server) and the resource occupation request, and can also be determined according to the security requirement of the user terminal on the requested service object data.
In general, if the security requirement of the user terminal on the request data and the requested service object data is not high, the request data can be directly sent to the primary resource pool proxy server based on the ethernet or the video network. Before a user terminal requests large-data-volume service object data, the user terminal sends a load query request to the video network core server, the video network core server feeds current load operation conditions back to the user terminal according to the load query request, and when the load of the video network core server is too high, the user terminal can directly send request data to a main resource pool proxy server based on the Ethernet. But when the confidentiality and the security of the request data by the user terminal are high, the request data can be sent to the main resource pool proxy server based on the video networking.
In the step, the data is requested in a mode of mutual cooperation through the Ethernet or the video network, so that the convenience and the efficiency of the data request can be greatly improved.
Because the requested service object data is located in the ethernet, a virtual terminal number in an idle state needs to be selected in advance from a core server of the video network to generate a binding relationship with the service object data in order to access the video network, the virtual terminal number and the service object data can be stored in a corresponding slave resource pool proxy server after generating the binding relationship, and then the slave resource pool proxy server can manage the virtual terminal and allocate the virtual terminal in different protocol conversion devices.
Therefore, in the embodiment of the present invention, the request data includes a target virtual terminal number in a binding relationship with the service object data;
and substep 2, the master resource pool proxy server sends a target virtual terminal number which generates a binding relationship with the service object data to the target slave resource pool proxy server based on the Ethernet or the video network.
And after receiving the target virtual terminal number, the target assistant resource pool proxy server inquires the target virtual terminal number for each protocol conversion device, then receives the service object data returned by the protocol conversion device, and then sends the service object data to the main resource pool proxy server.
Next, the master resource pool proxy server receives the business object data returned by the target slave resource pool proxy server for the request data based on an Ethernet or a video network; the service object data includes the target virtual terminal number.
In a preferred embodiment of the present invention, the master resource pool proxy server receives response data returned by the target slave resource pool proxy server for the request data based on ethernet or video network; the response data includes the business object data and the synchronization data. In specific implementation, after the target slave resource pool proxy server receives the service object data returned by the protocol conversion device, the synchronous data including the current load information of the slave resource pool proxy server and the service object data are packaged together, packaged into response data and returned to the master resource pool proxy server together, so that a circular feedback for requesting data allocation is formed for the master resource pool proxy server, the hardware pressure of the slave resource pool proxy server and the core server of the video network can be further reduced, the operation efficiency of the server deployed in a clustering manner is improved, and the current overall architecture has more cost performance.
For step S101 to step S103, the embodiment of the present invention is further described by using a specific example.
The protocol conversion device in the embodiment of the invention is a video network monitoring access server (also called a protocol conversion server), and the user terminal is a video network terminal.
Referring to fig. 2, a schematic diagram of an exemplary request for tuning flow according to the present invention is shown; in this example, one monitoring resource may be accessed by a plurality of cooperative transfer servers simultaneously based on the ethernet, and the plurality of cooperative transfer servers and the plurality of cooperative resource pool proxy servers establish communication connection based on the ethernet.
The protocol conversion server needs to access the monitoring resource of the monitoring A into the video network, then requests a virtual terminal number in an idle state from a video network core server, generates a binding relationship between the virtual terminal number and the identification mark of the monitoring resource, then sends the virtual terminal number generating the binding relationship and the identification mark of the monitoring resource to the video network core server for registration, and simultaneously stores the identification mark of the monitoring resource corresponding to the virtual terminal number, and then sends the virtual terminal number to a plurality of protocol slave resource pool proxy servers. Therefore, backup can be carried out among the cooperative resource pool proxy servers, and the problem that the audio and video data of the monitoring resource corresponding to the virtual terminal number managed by a certain cooperative resource pool proxy server cannot be called because the cooperative resource pool proxy server is full of load and cannot be used is solved. In the above configuration, the virtual terminal numbers managed between at least two slave resource pool proxy servers are partially the same.
Next, when receiving a stream-adjusting triggering operation for the monitoring resource of the monitoring A, the video network terminal generates stream-adjusting request data for the monitoring resource, then the video network terminal directly sends the stream-adjusting request data to the main resource pool proxy server based on the Ethernet, and the main resource pool proxy server analyzes the stream-adjusting request data after receiving the stream-adjusting request data to obtain a target virtual terminal number. And the master resource pool proxy server determines one with the target virtual terminal number and less number of currently managed virtual terminal numbers according to the currently stored virtual terminal numbers currently managed by the slave resource pool proxy servers, takes the slave resource pool proxy server as a target slave resource pool proxy server, and then sends a flow adjusting request to the target slave resource pool proxy server based on the Ethernet or the video network. After receiving the stream-adjusting request, the target assistant resource pool proxy server analyzes the stream-adjusting request to obtain a target virtual terminal number, then searches for the assistant transfer server storing the target virtual terminal number, sends the stream-adjusting request to one of the assistant transfer servers in a relatively idle state, then the assistant transfer server obtains audio and video data from the monitoring resource generating a binding relationship with the target virtual terminal number, and sends the obtained audio and video data to the target assistant resource pool proxy server based on the Ethernet.
Because the target assistant resource pool proxy server is also in communication connection with the video network core server based on the video network, after the target assistant resource pool proxy server obtains the audio and video data, the audio and video data can be selectively sent to the main resource pool proxy server based on the Ethernet or sent to the video network core server based on the video network. When the transmission quantity of the audio and video data is large, the video network core server or the main resource pool proxy server is occupied with excessive operation memory, therefore, a judgment program can be set in the target auxiliary resource pool proxy server, when the received business object data is judged to be the audio and video data type, the target auxiliary resource pool proxy server firstly sends a load query request to the video network core server or the main resource pool proxy server before sending the audio and video data to the video network core server or the main resource pool proxy server, the video network core server or the main resource pool proxy server feeds current load operation data back to the target auxiliary resource pool proxy server aiming at the load query request, and the target auxiliary resource pool proxy server carries data according to the current load of the video network core server or the main resource pool proxy server, and sending the audio and video data to the video networking core server or the main resource pool proxy server with smaller load operation data.
After the main resource pool proxy server receives the audio and video data, the audio and video data can be directly sent to the video networking terminal based on the Ethernet, or the audio and video data is firstly sent to a video networking core server, and then the audio and video networking core server forwards the audio and video data to the video networking terminal based on the video networking.
And after receiving the audio and video data, the video networking core server directly sends the audio and video data to the video networking terminal based on the video networking, and the video networking terminal decodes the audio and video data and presents the decoded audio and video data to a user so as to complete the whole stream adjusting process.
Referring to fig. 3, a flowchart illustrating steps of a second embodiment of a method for sending request data according to an embodiment of the present invention is shown, where the method is applied to a video network, and the video network is communicatively connected to an ethernet network, where the video network includes a video network core server, the ethernet network includes a master resource pool proxy server, and multiple slave resource pool proxy servers communicatively connected to the master resource pool proxy server; the video network core server is respectively in communication connection with the master resource pool proxy server and the plurality of slave resource pool proxy servers; the method may specifically comprise the steps of:

2. Video networking packet definition

As shown in the following table, the data packet of the access network mainly includes the following parts:
DA SA Reserved Payload CRC
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and its calculation method follows the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
DA SA Reserved label (R) Payload CRC
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
