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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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, the communication connection scheme provided by the embodiment of the invention follows the protocol of the video network, can control the video network terminal to establish communication connection through the video network conference management platform, and has the advantages of simple process and small limitation.
Example one
The communication connection method of the embodiment of the invention can be applied to the video network. The video network can comprise a video network conference management platform, a first video network terminal and a second video network terminal, wherein the video network conference management platform is bound with the first video network terminal. It should be noted that the video network may include a plurality of video network terminals, and the video network conference management platform may be bound to the plurality of video network terminals. In the embodiment of the present invention, a first video network terminal and a second video network terminal are taken as an example for description, the first video network terminal is a video network terminal of a calling party, the second video network terminal is a video network terminal of a called party, and each first video network terminal can be used as a first video network terminal and can also be used as a second video network terminal.
The video network terminal is a video network service landing device, an actual participant or a server of the video network service, and can be various conference set-top boxes, video telephone set-top boxes, operation trial set-top boxes and the like. After the video networking terminal is registered in the video networking server, the video networking server can perform normal video networking services, and after the video networking terminal is registered, the video networking server can allocate corresponding information such as a video networking number, a Media Access Control (MAC) address and the like for the video networking terminal.
Referring to fig. 5, a flowchart illustrating steps of a communication connection method according to a first embodiment of the present invention is shown.
The communication connection method of the embodiment of the invention can comprise the following steps:
The video networking conference management platform may provide a user interface.
In an optional implementation manner, an input box and a connection button may be provided in the user interface, when a user wants to establish a communication connection between the first video network terminal and the second video network terminal, the video network number of the first video network terminal and the video network number of the second video network terminal may be input in the input box, and then the connection button is clicked, so that the video network conference management platform may be triggered to generate a communication connection instruction.
In another optional implementation manner, the user interface may display the video networking number of the video networking terminal bound to the video networking conference management platform, or may display the video networking number of the video networking terminal that is not bound to the video networking conference management platform and a connection button, and when a user wants to establish communication connection between the first video networking terminal and the second video networking terminal, the user may select the video networking number of the first video networking terminal and the video networking number of the second video networking terminal, and then click the connection button, that is, the video networking conference management platform may be triggered to generate a communication connection instruction.
And after the video networking conference management platform generates the communication connection instruction, the communication connection instruction can be sent. The first video network terminal can receive the communication connection instruction. In the implementation, the video networking conference management platform encapsulates the communication connection instruction based on the video networking protocol to obtain the video networking protocol data packet encapsulated with the communication connection instruction. The video networking conference management platform sends a communication connection instruction based on video networking protocol encapsulation through the video networking, namely the video networking protocol data packet encapsulated with the communication connection instruction.
The communication connection instruction can carry information such as the video networking number of the first video networking terminal, the video networking number of the second video networking terminal, and an operation code representing the type of the instruction. And after the first video network terminal receives the communication connection instruction, analyzing the communication connection instruction and determining the instruction type of the communication connection instruction.
In an alternative embodiment, step 502 may include: the first video network terminal extracts an operation code representing the type of the instruction from the communication connection instruction; and acquiring the instruction type corresponding to the operation code representing the instruction type according to the corresponding relation between the preset operation code and the instruction type.
The corresponding relation between the operation code and the instruction type is preset, for example, the instruction type corresponding to the operation code 0001x is an instruction for indicating establishment of communication connection, the instruction type corresponding to the operation code 0002x is an instruction for indicating release of live broadcast, the instruction type corresponding to the operation code 0003x is an instruction for indicating watching of live broadcast, and the like. And the first video network terminal extracts the operation code from a field which is used for storing the operation code representing the instruction type in the communication connection instruction, and acquires the instruction type corresponding to the operation code according to the corresponding relation.
When the instruction type of the communication connection instruction is determined to be the instruction for indicating the establishment of communication connection, the first video network terminal acquires the video network number of the second video network terminal carried in the communication connection instruction, generates a communication connection request carrying the video network number of the second video network terminal, and of course, the communication connection request can also include the video network number of the first video network terminal. And after the communication connection request is generated, the first video network terminal sends the communication connection request.
In the implementation, the first video networking terminal encapsulates the communication connection request based on the video networking protocol to obtain the video networking protocol data packet encapsulated with the communication connection request. The first video network terminal sends a communication connection request based on video network protocol encapsulation through the video network, namely the video network protocol data packet encapsulated with the communication connection request.
And 505, after the first video network terminal receives the response of accepting the communication connection returned by the second video network terminal, the first video network terminal and the second video network terminal successfully establish the communication connection.
If the network condition is good and the current communication state of the second video network terminal is not communication, the second video network terminal can receive the communication connection request. The second terminal may choose to accept or reject after receiving the communication connection request.
If the second video network terminal accepts, the second video network terminal can generate a response of accepting the communication connection and return a response of accepting the communication connection.
