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 scheduling server receives the scheduling request sent by the client and forwards the scheduling request to the video network server according to the protocol of the video network, and the video network server selects the corresponding service server according to the load balance and informs the scheduling server of the access address of the service server so that the client can access the service server through the scheduling server.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for querying a service status of a video network according to the present invention is shown, where the method may be applied to a video network, and specifically may include:

step 501, a scheduling server obtains a status query request, where the status query request includes terminal identification information and service identification information.

Specifically, referring to fig. 6, a block diagram of a video networking service status query system according to the present invention is shown, wherein the video networking service status query system includes: a dispatch server 10, a video network server 20, a query request initiator 30 and a plurality of terminals 40.

Specifically, the dispatch server 10 is configured to receive a status query request sent by the query request initiator 30, convert data in the status query request into a video networking protocol data packet according to a video networking protocol, and send the video networking protocol data packet to the video networking server 20.

The video network server 20 is used for transmitting and processing files matched with the video network protocol, and in addition, when relevant video network services are carried out, a plurality of service servers exist, and the service servers can provide corresponding service services; when receiving a corresponding service request, the video network server 20 selects a service server with a load state meeting a preset condition from at least one service server, and notifies the scheduling server 10 of an access address of the service server, so that a service request initiating terminal can access the service server through the scheduling server 10.

The terminal 40 may have different terminal types or related scheduling software running in an application layer, and the terminal 40 may interact with the service server when requesting to obtain an access address of the service server to implement a related service.

In the embodiment of the present invention, the query request initiator 30 may be a terminal with different terminal types or related software running in an application layer, and the query request initiator 30 sends a status query request for the target terminal to the scheduling server 10, and extracts service status information of the corresponding service from a response returned by the scheduling server 10, so as to obtain information whether the target terminal is performing the corresponding service.

In this step, the status query request initiated by the query request initiator 30 may include terminal identification information and service identification information, where the terminal identification information is used to identify a target terminal requested by the query request initiator 30, as shown in fig. 6, the query request initiator 30 requests to query the service status information of the terminal 2, and therefore, the query request initiator 30 sets the terminal identification information of the terminal 2 in the status query request. The service identification information refers to the service specifically requested by the query request initiator 30, and it is assumed that the internet-of-view server 20 provides 0: release live broadcast, 1: watch live, 2: the three services 0, 1, and 2 of the video telephone may be service identification information corresponding to the three services, and the status query request may include one or more service identification information of the three services.

Step 502, after the scheduling server adds the terminal identification information and the service identification information to a video networking protocol data packet, the video networking protocol data packet is sent to a video networking server, and the video networking server forwards the video networking protocol data packet to a target terminal corresponding to the terminal identification information.

In the embodiment of the present invention, the video networking server implements processing and transmission of related data through a video networking protocol, and specifically, the scheduling server may convert the terminal identification information and the service identification information into corresponding codes according to the field number and length specified by the video networking protocol based on the requirements of the video networking protocol, and encapsulate the codes into a video networking protocol data packet, so that the video networking server implements processing and transmission of the data packet according to the functions defined by the codes.

For example, reference is made to table 1 below, which illustrates an example video networking protocol table of the present invention.

TABLE 1

Therefore, the scheduling server may further add a code 0x8405 and a code 0x1541 to the video networking protocol data packet on the basis of adding the terminal identification information and the service identification information corresponding to the type code to the video networking protocol data packet.

After the video networking server analyzes the video networking protocol data packet, the video networking server can realize transmission and processing of the video networking protocol data packet according to the code therein, for example, after the video networking server analyzes the code 0x8405, the video networking server can determine that the processing mode of the video networking protocol data packet is transparent transmission to the terminal, and then the video networking server can directly transmit the video networking protocol data packet to the corresponding target terminal without analyzing and processing other data in the video networking protocol data packet.

It should be noted that, in an implementation manner, the terminal identification information may include: the realization mode can correspondingly watch the live broadcast or video telephone service, and the two services can be realized only by at least two terminals, for example, in the video telephone service, a video telephone service initiator can be a source terminal, and a receiver can be a target terminal.

In another implementation, the terminal identification information may include only: the number of the source terminal, the realization mode can correspondingly release the live broadcast service, the service can be realized by 1 terminal, for example, in the release of the live broadcast service, the initiator of the live broadcast service can be the source terminal, and the receiver of the service is not concerned at this moment.

Step 503, after the target terminal adds the service state information to the video networking protocol data packet, the video networking protocol data packet is sent to a video networking server, and the video networking server forwards the video networking protocol data packet to the scheduling server.

In this step, when the video networking server transparently transmits the video networking protocol data packet to the target terminal, the target terminal may parse the video networking protocol data packet, acquire the service identification information corresponding to the type code, and generate corresponding service state information according to the service identification information corresponding to the type code, where the service state information may reflect whether the target terminal is performing a service corresponding to the service identification information. And after the target terminal adds the service state information to the video networking protocol data packet, the video networking protocol data packet is sent to a video networking server, and the video networking server transparently transmits the video networking protocol data packet to a scheduling server.

For example, assuming that the service identification information is 2 videophone service corresponding to type code, if the target terminal is currently performing the videophone service, service state information with a value other than 0 may be generated; if the target terminal does not currently perform the video telephone service, the service state information with the value of 0 can be generated.

Step 504, the scheduling server analyzes the service state information and the service identification information in the protocol data packet of the video networking, and adds the service state information and the service identification information to a response for the state query request.

In this step, the scheduling server parses the service status information and the service identification information in the protocol data packet of the video networking, and after the validity of the data is verified, the service status information and the service identification information are added to the response to the status query request.

After receiving the service state information and the service identification information in the response, the query request initiator may determine whether the target terminal is executing the service corresponding to the service identification information according to a value of 0 or non-0 of the service state information.

In summary, the method for querying a service status of a video network according to an embodiment of the present invention includes: the scheduling server acquires a state query request, wherein the state query request comprises terminal identification information and service identification information; after the dispatching server adds the terminal identification information and the service identification information to the video networking protocol data packet, the video networking protocol data packet is sent to a video networking server, and the video networking server forwards the video networking protocol data packet to a target terminal corresponding to the terminal identification information; after the target terminal adds the service state information to the video networking protocol data packet, the video networking protocol data packet is sent to a video networking server, and the video networking server forwards the video networking protocol data packet to a scheduling server; the invention can add the terminal identification information of the terminal to be inquired and the service identification information of the service to be inquired in the status inquiry request initiated by the inquiry request initiator, and the terminal identification information and the service identification information of the service to be inquired are added to the video network protocol data packet and transmitted to the target terminal according to the video network protocol regulation by the dispatching server, and the target terminal can return the service status information to the inquiry request initiator through the video network server and the dispatching server after adding the corresponding service status information to the video network protocol data packet according to the service identification information, so that the inquiry request initiator can obtain the value of the service status information, whether the target terminal executes the service corresponding to the service identification information is determined, the purpose of remotely inquiring the service state of the terminal is achieved, and the problem of scheduling state loss in the video networking system is solved.

Referring to fig. 7, a flow chart of the interaction steps of an embodiment of the method for querying the service status of the video networking of the present invention is shown, and the method comprises:

step 601, the scheduling server obtains a status query request, where the status query request includes terminal identification information and service identification information.

The step may specifically refer to the description of step 501, and is not described herein again.

Step 602, the scheduling server adds the terminal identification information, the management transparent transmission information, and the service identification information to the protocol data packet of the video networking.

In this step, for the service state query service, since the video networking server may only perform transparent transmission of the video networking protocol data packet, and does not perform operations such as data processing on the video networking protocol data packet, management transparent transmission information (code 0x8405) may be added to the video networking protocol data packet, so that the video networking server directly performs transparent transmission on the video networking protocol data packet according to the management transparent transmission information.

Step 603, the scheduling server stores the terminal identification information and the service identification information in the local of the scheduling server.

In the step, the scheduling server stores the terminal identification information and the service identification information in the local of the scheduling server, so that after receiving a new video networking protocol data packet returned by the target terminal, the terminal identification information and the service identification information in the new video networking protocol data packet are matched and checked with the local terminal identification information and the local service identification information stored in the scheduling server, and the purpose of verifying the data validity is achieved.

And step 604, the dispatching server sends the video networking protocol data packet to the video networking server.

Step 605, according to the management transparent transmission information, the video network server transmits the video network protocol data packet to the target terminal corresponding to the terminal identification information.

In this step, the scheduling server may add management transparent transmission information (code 0x8405) to the video networking protocol data packet, so that the video networking server directly performs transparent transmission on the video networking protocol data packet according to the management transparent transmission information.

Step 606, the target terminal adds the service state information corresponding to the service identification information to the video networking protocol data packet.

Optionally, in an implementation manner of the embodiment of the present invention, step 606 may specifically include:

substep 6061, when the local query of the target terminal finds that the service data corresponding to the service identification information exists, the target terminal adds the service state information with a non-zero value to the video networking protocol data packet.

Substep 6062, when the local query of the target terminal does not have the service data corresponding to the service identification information, the target terminal adds the service state information with a value of zero to the video networking protocol data packet.

Specifically, whether the target terminal is performing the service corresponding to the service identification information is determined, whether service data of the service corresponding to the service identification information exists may be queried in a memory of the target terminal, if so, the target terminal is determined to be performing the service corresponding to the service identification information, and if not, the target terminal is determined not to be performing the service corresponding to the service identification information.

It should be noted that, it is also possible to define that the service state information with a non-zero value is service data corresponding to the service identification information that is not locally queried by the target terminal, and the service state information with a zero value is service data corresponding to the service identification information that is locally queried by the target terminal.

Step 607, the target terminal sends the video networking protocol data packet to a video networking server.

Step 608, the video network server forwards the video network protocol data packet to the dispatch server.

In this step, since the management transparent transmission information (code 0x8405) exists in the video networking protocol data packet, the video networking server directly performs transparent transmission on the video networking protocol data packet according to the management transparent transmission information.

Step 609, the scheduling server analyzes and obtains the terminal identification information, the service state information and the service identification information in the video networking protocol data packet.

Step 610, when the analyzed terminal identification information and service status information match with the local terminal identification information and service identification information stored in the scheduling server, the scheduling server adds the service status information and the service identification information to a response for the status query request.

In the embodiment of the present invention, since the whole service state query service requires the cooperation between a plurality of terminals and a server, in the implementation process of one service state query service, the scheduling server needs to perform data inspection on the video networking protocol data packet sent to the target terminal by the scheduling server and the received video networking protocol data packet sent by the target terminal, so as to determine that the two video networking protocol data packets are for the service state query service.

Specifically, the scheduling server may match the analyzed terminal identification information and service status information with the local terminal identification information and service identification information stored in the scheduling server, and when the matching is confirmed, the scheduling server determines that the data is legal, and adds the service status information and the service identification information to the response to the status query request.
