The video networking technology has the flexibility, simplicity and low price of packet switching, and simultaneously has the quality and the safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.
Exchange technology (Switching Technology)
The video network adopts the two advantages of the asynchronization and the packet switching of the Ethernet, eliminates the Ethernet defect on the premise of full compatibility, has full-network end-to-end seamless connection, and is directly connected with the user terminal to directly bear the IP data packet. The user data does not need any format conversion in the whole network. The video networking is a higher-level form of Ethernet, is a real-time exchange platform, can realize real-time transmission of full-network large-scale high-definition video which cannot be realized by the current Internet, and pushes numerous network video applications to high definition and unification.
Server technology (Server Technology)
The server technology on the video networking and unified video platform is different from the server in the traditional sense, the streaming media transmission is based on connection-oriented basis, the data processing capability is irrelevant to the flow and the communication time, and a single network layer can contain signaling and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than that of data processing, and the efficiency is greatly improved by more than hundred times than that of a traditional server.
Accumulator technology (Storage Technology)
The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system for adapting to the ultra-large capacity and ultra-large flow media content, the program information in the server instruction is mapped to a specific hard disk space, the media content does not pass through the server any more, the media content is instantly and directly delivered to a user terminal, and the waiting time of the user is generally less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical motion of magnetic head seek of the hard disk, the resource consumption only accounts for 20% of the IP Internet of the same grade, but the concurrent flow which is 3 times greater than that of the traditional hard disk array is generated, and the comprehensive efficiency is improved by more than 10 times.

Service innovation technology (Service Innovation Technology)
The unified video platform fuses services with transmissions, whether a single user, private network users or a network aggregate, but automatically connects at a time. The user terminal, the set top box or the PC is directly connected to the unified video platform, so that various multimedia video services are obtained. The unified video platform adopts a menu type table allocation mode to replace the traditional complex application programming, and can realize complex application by using very few codes, thereby realizing 'infinite' new business innovation.
Networking of the video networking is as follows:
the video networking is a centrally controlled network structure, which may be of the tree network, star network, ring network, etc., but on the basis of this there is a need for a centralized control node in the network to control the whole network.
As shown in fig. 1, the view network is divided into an access network and a metropolitan area network.
The devices of the access network part can be mainly divided into 3 classes: node server, access switch, terminal (including various set-top boxes, code boards, memories, etc.). The node server is connected with an access switch, which can be connected with a plurality of terminals and can be connected with an Ethernet.
The node server is a node with a centralized control function in the access network, and can control the access switch and the terminal. The node server may be directly connected to the access switch or may be directly connected to the terminal.
Similarly, devices of the metropolitan area network portion can also be classified into 3 categories: metropolitan area server, node switch, node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.
The node server is the node server of the access network part, namely the node server belongs to the access network part and also belongs to the metropolitan area network part.
The metropolitan area server is a node with centralized control function in the metropolitan area network, and can control a node switch and a node server. The metropolitan area server may be directly connected to the node switch or directly connected to the node server.
Thus, the whole video network is a hierarchical centralized control network structure, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star, ring and the like.
The access network part can be vividly called as a unified video platform (part in a dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform can be interconnected and intercommunicated through metropolitan area and wide area video networking.

2. View networking data packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), source Address (SA), reserved bytes, payload (PDU), CRC.
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 data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), 256 possibilities are at most provided, the second byte to the sixth byte are metropolitan area network addresses, and the seventh and eighth bytes are access network addresses;
the Source Address (SA) is also composed of 8 bytes (bytes), defined identically to the Destination Address (DA);
the reserved bytes consist of 2 bytes;
the payload portion has different lengths according to the types of the different datagrams, and is 64 bytes if it is various protocol packets, and 32+1024=1056 bytes if it is a unicast packet, and is of course 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 the metropolitan area network is a pattern, there may be 2 or even more than 2 connections between two devices, i.e. there may be more than 2 connections between node switches and node servers, node switches and node switches, node switches and node servers. However, the metropolitan area network address of the metropolitan area network device is unique, and in order to accurately describe the connection relationship between metropolitan area network devices, parameters are introduced in the embodiment of the present invention: a tag to uniquely describe a metropolitan area network device.
The definition of label in this specification is similar to that of MPLS (Multi-Protocol Label Switch, multiprotocol label switching), and assuming that there are two connections between device a and device B, there are 2 labels for packets from device a to device B and 2 labels for packets from device B to device a. The label is split into label and label out, and assuming that the label (in label) of the packet entering the device a is 0x0000, the label (out label) of the packet when leaving the device a may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, that is, the address allocation and label allocation of the metropolitan area network are all led by the metropolitan area server, the node switch and the node server are all passively executed, which is different from the label allocation of the MPLS, which is the result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metropolitan area network mainly includes the following parts:
DA SA Reserved label (Label) Payload CRC
I.e. Destination Address (DA), source Address (SA), reserved bytes (Reserved), labels, payload (PDU), CRC. Wherein the format of the tag may be defined with reference to the following: the tag is 32 bits, with the high 16bit reservation, with only the low 16bit, and its position is between the reserved bytes and payload of the packet.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for responding to a call according to an embodiment of the present invention is applied to a streaming server, where the streaming server is communicatively connected to a push server, and may specifically include the following steps:
step 501, receiving a call request for a second client sent by a first client;
the streaming media server is used for managing the call service between the first client and the second client, after the first client and the second client log on the streaming media server, the call service can be carried out between the first client and the second client through the streaming media server, the call request is sent to the streaming media server, and the streaming media server forwards the call request to the opposite end, so that the call service connection between the two clients is established, and the audio and video call is realized. Under the condition that the client is not limited by the network, the client is ensured to stably operate, and is stably linked with the streaming media server, so that the communication is ensured not to be interrupted. When the switching network or network fluctuation occurs and the link with the server is disconnected, the link is re-linked, the communication with the streaming media server is restored, and the normal incoming call and outgoing call are ensured.
In a specific implementation, the first client may be used as a calling terminal, and the second client may be used as a called terminal, or of course, the first client may be used as a called terminal, and the second client may be used as a calling terminal.
When the first client needs to initiate a call to the second client, the first client may generate a call request for the second client, and send the call request for the second client to the streaming server. The streaming server may receive a call request sent by the first client for the second client.
The call request may be a request to initiate a call service, which may include an audio call service, a video call service, a conference service, and the like. The call request may carry an identification code of the source terminal (e.g., the first client) and an identification code of the destination terminal (e.g., the second client), where the identification codes are used to uniquely identify the clients.
Step 502, when the second client side drops, generating a push message according to the call request;
when the second client is disconnected, i.e. the link between the second client and the streaming media server is disconnected, a push message can be generated according to the call request.
Specifically, when the second client is logged in but loses a link with the service management server, or the second client is not opened or is not logged in. When the terminal device is on the screen for a long time or the application program of the second client runs in the background of the terminal device for a long time, because the application program of the second client does not enter the white list, the network of the second client is limited by the mobile phone system at this time, so that the second client loses the link with the service management server, or in the case that the second client is not started, the client is off line, and at this time, the streaming media server cannot establish the communication link between the first client and the second client according to the call request.
In the embodiment of the invention, in order to avoid that the second client cannot timely respond to the call request initiated by the first client, a push message can be generated according to the call request.
The push message may be a message for notifying the second client that there is a call request from the first client, and the push message may include an identification code corresponding to the first client, so that the second client may determine, from the push message, that it is the first client that initiates the call request.
Step 503, calling an interface of the push server, and pushing the push message to the target mobile device corresponding to the second client; the second client is used for receiving the push message through the target mobile device and responding to the call request according to the push message.
The push server may push the push message to the mobile device.
In the embodiment of the invention, the streaming media server can call the interface of the pushing server, and the pushing server determines the target mobile device corresponding to the second client according to the pushing message and pushes the pushing message to the target mobile device corresponding to the second client. The second client may thus receive the push message via the target mobile device to respond to the call request in accordance with the push message.
In a preferred embodiment of the present invention, the following sub-steps may be further included before the step 501:
receiving a login request sent by the second client; when the login request is judged to meet the preset condition, acquiring an account number identifier and an equipment code corresponding to the second client; binding the account number identification and the equipment code in a first preset data table.
In the embodiment of the invention, the streaming media server may receive a login request sent by the second client, where the login request is used to request to establish a communication link between the second client and the streaming media server.
After receiving the login request, it may be determined whether the login request meets a preset condition, where the preset condition may be a preset determination condition, for example, the preset condition is that the streaming server is logged in for the first time. Specifically, the streaming media server may count the frequency of the login service management of the client (including the first client, the second client, etc.), determine whether the second client is the first login streaming media server according to the counted frequency, and determine that the login request meets the preset condition when the second client is the first login streaming media server.
When the login request is judged to meet the preset condition, the account identifier and the equipment code corresponding to the second client side can be obtained. The account identifier may be a unique identifier for identifying the second client, and the account identifier may be distributed by the streaming media server or set by the user, where the user needs to determine the uniqueness of the account identifier when setting by the user. The device code may be a unique identification code of the mobile device running the second client, e.g. the device code is a MAC (Media Access Control Address ) address of the mobile device.
The first preset data table may be a preset data table in the streaming media server, and is used for storing account identifiers and device codes, and a binding relationship between the account identifiers and the device codes. In the embodiment of the invention, after the account identifier and the equipment code corresponding to the second client are acquired, the streaming media server can bind the account identifier and the equipment code after the first preset data table, namely, the binding relation between the acquired account identifier and the acquired equipment code is established.
In a preferred embodiment of the present invention, the method may further comprise the steps of:
and sending a registration message aiming at the account identification and the equipment code of the second client to the push server.
In the embodiment of the invention, the streaming media server can generate the registration message of the account identifier and the equipment code of the second client, and send the registration message of the account identifier and the equipment code of the second client to the push server.
In a preferred embodiment of the present invention, the step 502 may include the following sub-steps:
searching a target account number identification corresponding to the second client from a first preset data table according to the call request; and generating a push message comprising the target account number identification.
Specifically, the call request may carry an identification code of the second client, and the streaming media server may determine the second client to be called by extracting the identification code in the call request, and further, search a target account identifier corresponding to the second client from the first preset data table; a push message is generated that includes the identification of the target account number.
In a preferred embodiment of the present invention, the second client dropping includes at least one of:
the second client runs on the target mobile device in a background mode for more than a preset time period, or the target mobile device locks a screen for more than the preset time period; the second client is not logged in or started on the target mobile device.
In the embodiment of the invention, a call request sent by a first client for a second client is received through a streaming media server; when the second client side is disconnected, generating a push message according to the call request; and calling an interface of a pushing server to push the pushing message to the target mobile equipment corresponding to the second client. By introducing the push server, when the second client side drops, an interface of the push server is called to enable the push message to be generated to the target mobile device, so that the second client side can receive the push message through the target mobile device and respond to the call request according to the push message, and the situation that the call request initiated by the first client side cannot be responded in time when the second client side drops is avoided.
Referring to fig. 6, a flowchart illustrating steps of another method embodiment of responding to a call according to an embodiment of the present invention is applied to a push server, where the push server is communicatively connected to a streaming server, and may specifically include the following steps:
step 601, receiving a push message sent by the streaming media server; the push message comprises a target account number identifier;
in the embodiment of the invention, the push server can be in communication connection with the streaming media server, so that a push message generated by the streaming media server can be received, and the push message comprises the target account identifier.

in the embodiment of the invention, the push server can extract the target account identification in the push message.
Step 603, determining a target device code matched with the target account identifier from a second preset data table;
in the embodiment of the invention, after the target account number identification in the push message is extracted, the target device code matched with the target account number identification can be determined from the second preset data table.
The second preset data table may be a preset data table, and the second preset data table in the push server may have the same data structure as the first preset data table in the streaming media server, so that the same data may be stored in the second preset data table in the push server and the first preset data table in the streaming media server.
The second preset data table may store an account identifier, a device code, and a binding relationship between the account identifier and the device code. The device code with the binding relation with the target account number identification is the target device code by searching the device code with the binding relation with the target account number identification from the second preset data table.
Step 604, pushing the push message to the target mobile device corresponding to the target device code.
In the embodiment of the invention, the push server can push the push message to the target mobile device corresponding to the target device code.
