2. Video networking 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 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 is calculated in accordance with 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 metro network 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.

Based on the characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the point positions of all terminal equipment are shown on the map at the web client, and the user can dial the video telephone function by clicking the link at the terminal selected on the map.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for video call according to the present invention is shown, where the method is applied to a video network, where the video network includes a terminal device and a server, and the method specifically includes the following steps:

substep S12, receiving the terminal data returned by the server according to the downlink communication link configured for the terminal device;

and a substep S13 of calling map data and presenting the terminal device on the map data based on the terminal data.

When the terminal equipment is displayed on the map, terminal data related to the terminal equipment can be requested from the server, the server collects the terminal data and returns the terminal data to the terminal equipment after receiving the request, a web client on the terminal equipment arranges the terminal data based on the terminal data, and the terminal data is filled into the map data, so that each terminal equipment in the video network can be displayed on the map data.

In the embodiment of the present invention, after the terminal data of the terminal device is acquired from the server, the existing GIS (Geographic Information System) map data may be called, and the terminal data is rendered on the map data for display.

In this practical application, the video network is a network with a centralized control function, and includes a main control server and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is that a table is configured for a downlink communication link of a current service by notifying a switching device by the main control server, and then a data packet is transmitted based on the configured table.

Namely, the communication method in the video network includes:

the main control server configures a downlink communication link of the current service;

and transmitting the data packet of the current service sent by the source terminal to a target terminal (such as a video network terminal) according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: informing the switching equipment related to the downlink communication link of the current service to allocate a table;

further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

the main control server obtains the downlink communication link information of the current service according to a service request protocol packet initiated by a source terminal, wherein the downlink communication link information comprises the main control server participating in the current service and the downlink communication port information of an access switch;

the main control server sets a downlink port to which a data packet of the current service is directed in a data packet address table in the main control server according to the downlink communication port information of the main control server; sending a port configuration command to a corresponding access switch according to the downlink communication port information of the access switch;

the access switch sets the downstream port to which the data packet of the current service is directed in the data packet address table in the access switch according to the port configuration command.

For multicast communication services (such as video conference and video monitoring) in the access network, the step of the master server acquiring downlink communication link information of the current service may include the following sub-steps:

the method comprises the steps that a main control server obtains a service request protocol packet which is initiated by a target terminal and applies for multicast communication service, wherein the service request protocol packet comprises service type information, service content information and an access network address of the target terminal; wherein, the service content information comprises a service number;

the main control server extracts the access network address of the source terminal in a preset content-address mapping table according to the service number;

the main control server acquires a multicast address corresponding to a source terminal and distributes the multicast address to a target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

Step 502, according to the selection request of the user, determining the target terminal device on the map data.

For the video network user, the terminal device to be linked can be selected on the map, and the terminal device selected by the user is the target terminal device.

Step 503, invoking the server to perform a video call with the target terminal device.

After the target terminal equipment is determined on the map data, the video network user platform (web client) sends a video telephone request to the video network bottom layer special service (video network server), the video network bottom layer special service receives the request, then calls the terminal equipment and returns the terminal equipment to the video network user platform, and the video call between the web client and the target terminal equipment is established.

In a preferred embodiment of the present invention, the step 503 may include the following sub-steps:

substep S21, sending a videophone request to the server; the server is used for forwarding the video telephone request to a target terminal device and judging a call state according to a response message fed back by the target terminal device;

and a substep S22, performing a video call with the target terminal device through the server when the call status is yes to answer.

After a user of the video network determines a target terminal device on map data of a web client, a video telephone request is sent to a special service of the bottom layer of the video network, the video telephone request is forwarded to the target terminal device by the special service of the bottom layer of the video network, if the target terminal device agrees to answer or refuses to answer, a response message is fed back to the special service of the bottom layer of the video network, after the special service of the bottom layer of the video network is received, whether the target terminal agrees to answer or not is determined according to the response message, and if the answer is agreed, the web client can carry out video conversation with the target terminal through the special service of the bottom layer.

In a preferred embodiment of the present invention, the step 503 may further include the following sub-steps:

and a substep S23, receiving a message of refusing to answer, which is fed back by the server, when the call state is refusing to answer.

According to the foregoing, the user of the target terminal device can select to accept or reject, and if the user agrees to accept, the server feeds back a message that the target terminal device rejects the video call to the web client.

and a substep S24, if the server does not receive the response message fed back by the target terminal within a preset time, receiving a message of failed listening fed back by the server.

In practice, there is also a case that the target terminal device does not feedback the request of the videophone, and in order to avoid sending the request all the time, it may be set that after the preset time is reached, a message that the target terminal device agrees or rejects is not received, and then a message that the answering fails is fed back to the web terminal.

For the embodiment of the present invention based on the dedicated service at the bottom layer of the video network, a flow of data interaction between the video network user platform and other terminal devices (e.g., palm top, mobile terminal, monitor, etc.) is shown in fig. 6.

In order to make the embodiment of the present invention better understood by those skilled in the art, a specific example is used below to describe a process of linking terminals to perform a video call. Referring to fig. 7, a flow chart of determining a call state of a target terminal device according to the present invention is shown, and the specific process includes:

1. a user selects target terminal equipment at a web client;

2. calling the other side, namely the target terminal equipment, through the special service of the bottom layer of the video network;

3. the other party receives the call request and selects to approve the connection or refuse the connection;

4. and receiving a message of agreeing to connect (or disagreeing) fed back by the other party.

In the calling process, if the calling is not connected, the calling is continued until the user hangs up or the opposite party rejects. Of course, considering the situation that the possible party is not answered by the other party, it can be set that if no refusal or agreement message is received in the preset time, the call is determined to be failed, and the call is ended.

In the embodiment of the invention, in order to ensure the real-time performance of data, a websocket is selected for data communication. Wherein, Websocket: websocket is a protocol specification proposed by html 5. The websocket stipulates a communication specification, and a connection similar to tcp can be established between a client (browser) and a server (webserver) through a handshake mechanism, so that communication between the client and the server is facilitated.

Of course, other communication protocols may also be used, such as ajax data communication, ajax being an encapsulation of XMLHttpRequest (XHR) objects used to exchange data with the server in the background. The client sends a request to the server, and the server responds to the request of the client and returns data. Are short-circuited.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
