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:

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:

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, wherein an internet virtual terminal corresponding to the internet terminal, a video network virtual terminal corresponding to the video network terminal and a blank number management module are preset in the streaming media server; after receiving the query request of the video networking terminal, the streaming media server can acquire an idle number through the idle number management module, determine that the video networking virtual terminal corresponding to the idle number is a binding video networking virtual terminal, then bind the binding video networking virtual terminal with the video networking terminal, and modify the state of the idle number into an occupied state; then, by binding the video network virtual terminal and the internet virtual terminal, real-time services of the video network terminal and the internet terminal are established; the embodiment of the method binds the corresponding virtual terminal of the video network to the video network terminal in real time according to the query request of the video network terminal, if the real-time service is finished, the number corresponding to the virtual terminal of the video network is recovered by the empty number management module, and the state of the modified number is in an idle state, the bound virtual terminal of the video network can be redistributed in the next service, and the service requirement can be fully met by using the limited resources of the streaming media server through a dynamic multiplexing method.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a resource allocation method based on video networking according to the present invention is shown, where the method may be applied to a streaming server, where an internet virtual terminal corresponding to an internet terminal, a video networking virtual terminal corresponding to a video networking terminal, and a blank number management module are preset in the streaming server.

In the embodiment of the present invention, the internet terminal is a terminal using an internet protocol for communication, for example, a terminal communicating through a TCP/IP protocol, and specifically may be a PCTV, a computer terminal, a multimedia player, and the like, which is not limited in this embodiment of the present invention; the Internet virtual terminal is a virtual terminal which can communicate with the Internet terminal through an Internet protocol and is arranged in the streaming media server; the video network terminal is a terminal which uses a video network protocol for communication, and specifically can be a computer terminal, a multimedia player and the like which are accessed to the video network, and the embodiment of the invention does not limit the terminal; the video networking virtual terminal is a virtual terminal which can communicate with the video networking terminal through a video networking protocol and is arranged in the streaming media server; the null number management module is a virtual terminal of the video network for managing undistributed processing services.

The method specifically comprises the following steps:

step 501: and receiving the query request of the video network terminal.

In the embodiment of the invention, when the video network terminal wants to watch the Internet live broadcast or perform the services such as video telephone, conference and the like with the Internet terminal, the video network terminal can send an inquiry request to the streaming media server, and the inquiry request can be used for inquiring whether a video network virtual terminal capable of providing service exists in the streaming media server.

Step 506: and if the real-time service is finished, the number corresponding to the virtual terminal of the binding video network is recovered through the empty number management module, and the state of the number is modified into an idle state.

In the embodiment of the invention, if the real-time service of the video network terminal and the internet terminal is detected to be finished, the binding video network virtual terminal can be in a non-service state, so that the state of the number corresponding to the binding video network virtual terminal can be modified into an idle state, and the number is recovered through the idle number management module for the next use.

In a specific application, whether the real-time service of the video network terminal and the internet terminal is finished or not can be determined by detecting the occupation condition of the communication interface of the video network terminal and the internet terminal, for example, if the video network terminal is in the real-time service and is in communication with the communication interface B of the internet terminal through the communication interface a, and if the video network terminal is detected that the communication interface a of the video network terminal and the communication interface B of the internet terminal are not occupied within a preset time, the real-time service can be considered to be finished, wherein the preset time can be set according to an actual application scene. Accordingly, if the communication interface a of the video network terminal and the communication interface B of the internet terminal are occupied, the real-time service may be considered to be not ended.

In summary, the embodiment of the present invention can be applied to a streaming media server of a video network, in which an internet virtual terminal corresponding to an internet terminal, a video network virtual terminal corresponding to a video network terminal, and a blank number management module are preset in the streaming media server; after receiving the query request of the video networking terminal, the streaming media server can acquire an idle number through the idle number management module, determine that the video networking virtual terminal corresponding to the idle number is a binding video networking virtual terminal, then bind the binding video networking virtual terminal with the video networking terminal, and modify the state of the idle number into an occupied state; then, by binding the video network virtual terminal and the internet virtual terminal, real-time services of the video network terminal and the internet terminal are established; the embodiment of the method binds the corresponding virtual terminal of the video network to the video network terminal in real time according to the query request of the video network terminal, if the real-time service is finished, the number corresponding to the virtual terminal of the video network is recovered by the empty number management module, and the state of the modified number is in an idle state, the bound virtual terminal of the video network can be redistributed in the next service, and the service requirement can be fully met by using the limited resources of the streaming media server through a dynamic multiplexing method.

Preferably, step 609 may comprise:

and sending the video networking response information to the video networking terminal through the binding video networking virtual terminal.

In the embodiment of the invention, because the response information sent by the internet terminal can be identified by the internet, the streaming media server can convert the response information of the internet into the response information of the video network which can be identified by the video network according to the preset protocol, and then sends the response information of the video network to the video network terminal through the binding video network virtual terminal.
