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 various protocol packets are adopted, and is 32 + 1024 = 1056 bytes if a unicast data packet is adopted, and is of course not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

Packet definition for metropolitan area network

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 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 network access scheme of the mobile terminal provided by the embodiment of the invention follows the protocol of the video network, and the mobile terminal can access the internet through the video network under the condition of not being connected with the internet.

Example one

The network access method of the mobile terminal of the embodiment of the invention can be applied to video networking. In the video network, a video network terminal and a video network Modem are included. Wherein, the mobile terminal can include: tablet computers, cell phones, notebook computers, and the like. The video network terminal is a video network service landing device, an actual participant or a server of the video network service, the video network terminal can be various conference set-top boxes, video telephone set-top boxes, operation teaching set-top boxes, streaming media gateways, storage gateways, media synthesizers and the like, the video network terminal is registered on the video network server to perform normal service, and the video network server can be the node server. The video networking Modem can access two networks of the video networking and the Internet through the video networking convergence gateway, and the video networking Modem has the capacity of converging the video networking and the Internet data protocol, so that the video networking terminal needs to be manufactured into an intelligent network terminal capable of providing the mobile terminal to access the Internet by means of the video networking Modem and the wireless network card.

Referring to fig. 5, a schematic diagram of device interaction for network access of a mobile terminal according to a first embodiment of the present invention is shown. As can be seen from fig. 5, the video networking Modem may be connected to two networks, namely, the internet and the video networking, the video networking Modem and the video networking terminal may perform bidirectional interaction based on the video networking, and the video networking terminal and the mobile terminal may perform bidirectional interaction based on a WIFI (WIreless-FIdelity) hotspot.

Referring to fig. 6, a flowchart illustrating a step of a network access method of a mobile terminal according to a first embodiment of the present invention is shown.

The network access method of the mobile terminal of the embodiment of the invention can comprise the following steps:

step 601, the video network terminal receives the first data sent by the mobile terminal, and sends the first data to the video network Modem through the video network after performing first protocol conversion on the first data.

In the embodiment of the invention, as the mobile terminal can not access the internet, the mobile terminal can be set to access the internet through the video networking terminal and the video networking Modem.

The mobile terminal and the video network terminal can be connected through the WIFI hotspot. Therefore, the video network terminal can firstly open the WIFI hotspot of the video network terminal, and the mobile terminal can be connected with the WIFI hotspot on the video network terminal, so that a WIFI sharing network is established between the video network terminal and the mobile terminal.

When the mobile terminal has the requirement of accessing the internet, the corresponding first data can be sent to the video network terminal. For example, if the mobile terminal wants to perform a web page search, the first data may be web page information (including a web page address, etc.); if the mobile terminal wants to conduct instant chatting, the first data may be chatting information (including chatting contents, chatting objects, etc.). Specifically, the mobile terminal can send the first data to the video network terminal through the WIFI shared network. The first data may be specifically sent according to a Socket communication mode. Two programs on the network exchange data via a bidirectional communication link, one end of which is called a Socket. At least one pair of port numbers (sockets) is required to establish the network communication connection. Socket is essentially A Programming Interface (API), and encapsulates TCP/IP, which also provides an interface for programmers to use for network development, namely Socket programming interface. Sockets provide the capability for network communications. Socket, also commonly referred to as "Socket," is used to describe IP addresses and ports, and is a handle of a communication chain that can be used to implement communication between different virtual machines or different computers.

It should be noted that, in the embodiment of the present invention, the WIFI hotspot provided by the video network terminal may be a WIFI hotspot based on the video network, and therefore, a WIFI shared network based on the video network is established between the mobile terminal and the first video network terminal.

In specific implementation, the mobile terminal may encapsulate the first data into a first internet protocol data packet based on an internet protocol, and send the first internet protocol data packet to the video networking terminal through the WIFI shared network. The Internet Protocol may be TCP (Transmission Control Protocol), IP (Internet Protocol), UDP (User Datagram Protocol), ICMP (Internet Control Message Protocol), and the like.

In the embodiment of the invention, the video network terminal registers the MAC address of the virtual terminal node on the video network server, which is equivalent to that one video network terminal comprises a virtual terminal node and an entity video network terminal, the message types of the virtual terminal node and the server are loaded into a Linux kernel of the video network terminal through a netlink, and the virtual terminal node is responsible for interacting video network data with an internet data message with the video network Modem. Therefore, the process executed by the video networking terminal in the embodiment of the present invention may be specifically understood as a process executed by a virtual terminal node in a Linux kernel of the video networking terminal. The video network terminal can comprise a wlan interface and an eth interface, and a virtual terminal node of the video network terminal can interact with the mobile terminal through the wlan interface and interact with the video network Modem through the eth interface.

The mobile terminal sends the first data to the video network terminal (specifically to a virtual terminal node of the video network terminal), and the video network terminal sends the first data to the video network Modem after receiving the first data.

Because the video network terminal and the video network Modem are communicated through the video network, the video network terminal performs first protocol conversion on the first data and then sends the first data to the video network Modem through the video network. In a specific implementation, the video networking terminal converts the first internet protocol data packet into a first video networking protocol data packet encapsulating the first data based on the video networking protocol. Specifically, the video networking terminal decapsulates the first internet protocol data packet to obtain first data therein, and encapsulates the first data into a first video networking protocol data packet based on a video networking protocol. And after the video networking terminal packages the first video networking protocol data packet, the first video networking protocol data packet is sent to the video networking Modem through the video networking. Wherein, the video networking protocol can be a video networking V2V protocol.

In a preferred embodiment, the first video network protocol data packet may include first path information indicating a transmission path of the first video network protocol data packet in the video network. The first path information may comprise a source address and a destination address, wherein the source address may comprise a MAC address of the virtual end node and the destination address may comprise an IP address of the video networking Modem. Therefore, the video network terminal can send the first video network protocol data packet to the video network Modem through the video network according to the first path information through the virtual terminal node.

When a mobile terminal is connected with a video networking terminal WIFI hotspot, a transmitted first internet protocol data packet enters a virtual terminal node of the video networking terminal through a wlan interface, the virtual terminal node defines a data structure of an NF _ hook _ ops storage hook in a Linux kernel, the content of the structure body is registered in an NF _ hooks linked list, when the virtual terminal node operates to an NF _ INET _ POST _ ROUTING mounting point of an nat mechanism in iptables, a video networking message transmitting function is called, first data fragments in a data field area of the first internet protocol data packet are segmented, and each fragment is packaged into the first video networking protocol data packet together with a packet header of a video networking v2v protocol. And the virtual terminal node of the video networking terminal dials a video telephone with the video networking Modem, a communication tunnel is established, the video networking terminal finds the corresponding video networking Modem through the destination IP address index, and the first video networking protocol data packet which is packaged is sent to the video networking Modem.

Step 602, if the video networking Modem determines that the first data is internet data, performing second protocol conversion on the first data and then sending the first data to the internet device corresponding to the first data through the internet.

After receiving the first video networking protocol data packet, the video networking Modem analyzes the first video networking protocol data packet to obtain first data in the first video networking protocol data packet, and judges whether the first data is internet data.

For example, when the video network terminal performs the first protocol conversion on the first data in step 601, a type identifier may be added to the first data, where the type identifier is used to indicate that the first data is internet data. In a specific implementation, the video networking terminal may add the type identifier to a first video networking protocol data packet when the first data is encapsulated into the first video networking protocol data packet based on the video networking protocol. If the type identification exists after the analysis of the video networking Modem, the first data can be determined to be internet data according to the type identification.

If the video networking Modem judges that the first data are internet data, the video networking Modem transmits the first data to the internet because the first data are sent by the video networking terminal based on a video networking protocol, and the video networking Modem performs second protocol conversion on the first data and then transmits the first data to the internet equipment corresponding to the first data through the internet.

In a specific implementation, the video networking Modem converts the first video networking protocol data packet into a second internet protocol data packet which encapsulates the first data based on an internet protocol; and the video networking Modem transmits the second Internet protocol data packet to the Internet equipment corresponding to the first data through the Internet. Specifically, the video networking Modem decapsulates the first video networking protocol data packet to obtain first data therein, and encapsulates the first data into a second internet protocol data packet based on the inter-video networking protocol, that is, removes a video networking v2v protocol header and adds a corresponding IP protocol header. And after the video networking Modem packages the second Internet protocol data packet, the second Internet protocol data packet is sent to the Internet equipment corresponding to the first data through the Internet.

The video networking Modem can determine the Internet equipment corresponding to the first data according to the first data. For example, if the first data is web page information (including a web page address, etc.), the internet device corresponding to the first data may be a server corresponding to the web page address. If the first data is chat information (including chat content, chat objects and the like), the internet device corresponding to the first data may be a server corresponding to the chat tool, and the server forwards the first data to an internet device (such as a mobile phone, a tablet and the like) used by the chat object.

Step 603, the video networking Modem receives second data returned by the internet device for the first data, and sends the second data to the video networking terminal through the video networking after third protocol conversion is performed on the second data.

After the internet device corresponding to the first data receives the first data, the internet device may return second data for the first data. For example, if the first data is web page information (including web page addresses, etc.), the second data may be web page data corresponding to the web page addresses. If the first data is chat information (including chat content, chat objects and the like), the second data can be the chat content returned by the chat objects.

In a specific implementation, the internet device may encapsulate the second data into a third internet protocol data packet based on the internet protocol, and transmit the third internet protocol data packet to the video networking Modem through the internet. That is, the video networking Modem receives a third internet protocol data packet, which is returned by the internet device for the first data and encapsulates the second data based on the internet protocol.

The second data is returned by the internet equipment, and the video networking Modem transmits the second data to the video networking terminal, so that the video networking Modem performs third protocol conversion on the second data and then transmits the second data to the video networking terminal through the video networking.

In a specific implementation, the video networking Modem converts the third internet protocol packet into a second video networking protocol packet encapsulating the second data based on the video networking protocol. Specifically, the video networking Modem decapsulates the third internet protocol data to obtain second data therein, and encapsulates the second data into a second video networking protocol data packet based on the video networking protocol. And after the second video networking protocol data packet is obtained by the video networking Modem in a packaging mode, the second video networking protocol data packet is sent to the video networking terminal through the video networking.

In a preferred embodiment, the second video network protocol data packet may include second path information indicating a transmission path of the second video network protocol data packet in the video network. The second path information may comprise a source address and a destination address, wherein the source address may comprise an IP address of the video networking Modem and the destination address may comprise a MAC address of the virtual end node. Therefore, the video networking Modem can send the second video networking protocol data packet to the video networking terminal through the virtual terminal node through the video networking according to the second path information.

And step 604, if the video networking terminal determines that the second data is internet data, performing fourth protocol conversion on the second data and then sending the second data to the mobile terminal.

And after receiving the second video networking protocol data packet, the video networking terminal analyzes the second video networking protocol data packet to obtain second data in the second video networking protocol data packet, and judges whether the second data is internet data or not.

For example, when the video networking Modem performs the third protocol conversion on the second data in step 603, a type identifier may be added to the second data, where the type identifier is used to indicate that the second data is internet data. In a specific implementation, the video networking Modem may add the type identifier to a second video networking protocol data packet when the second data is encapsulated into the second video networking protocol data packet based on the video networking protocol. And if the type identification exists after the video networking terminal analyzes the data, determining that the second data is the internet data according to the type identification.

If the video network terminal judges that the second data is internet data, the video network terminal performs fourth protocol conversion on the second data and then sends the second data to the mobile terminal of the internet as the second data is sent by the video network Modem based on the video network protocol and the video network terminal sends the second data to the mobile terminal of the internet.

In a specific implementation, the video network terminal converts the second video network protocol data packet into a fourth internet protocol data packet which encapsulates second data based on an internet protocol; and the video networking terminal sends the fourth Internet protocol data packet to the mobile terminal. Specifically, the video networking terminal decapsulates the second video networking protocol data packet to obtain first data therein, and encapsulates the second data into a fourth internet protocol data packet based on the internet protocol. And after the video networking terminal packages the fourth Internet protocol data packet, the fourth Internet protocol data packet is sent to the mobile terminal through the WIFI shared network.

And after receiving the fourth internet protocol data packet, the mobile terminal analyzes the fourth internet protocol data packet to obtain second data, so that the mobile terminal can access the internet under the condition of not connecting with the internet. For example, if the second data is web page data corresponding to a web page website, the user of the mobile terminal may view the web page data, thereby obtaining the required content. If the second data is the chat content returned by the chat object, the user of the mobile terminal can know the reply of the chat object, and the instant chat with the chat object is realized.

In the embodiment of the invention, a network cable on a physical layer link layer can be used as a transmission carrier of a video network and an internet at the same time, an internet data packet is converted into a path of data of the video network through the video network cable and the internet cable accessed by a video network Modem and is transmitted to a video network terminal, the video network terminal filters and encapsulates the received video network data packet into internet data through a virtual terminal node of a Linux kernel layer, the internet data is forwarded to a wireless network card of the video network terminal through iptables and is transmitted to an accessed mobile terminal through a WIFI hotspot.

The technical scheme provides a virtual terminal node based on a video networking Modem at a video networking terminal for carrying out eth interface monitoring on a Linux kernel network layer, and a data packet is packaged and unpacked, so that the video networking and the Internet are perfectly combined, the defect that a traditional video networking terminal cannot surf the Internet is overcome by the function of surfing the Internet through the video networking terminal, and meanwhile, the mobile terminal is provided with Internet access service by sharing a WIFI hotspot through a wireless network card module accessed by the video networking terminal. The video networking terminal is mainly responsible for receiving internet data packaged into a video networking data packet by the video networking Modem, unpacking and restoring the internet data in the Linux kernel, sending the restored internet data to the mobile terminal shared by the internet or the WIFI hotspot, receiving the internet data packet responded by the mobile terminal, packaging the internet data packet in the Linux kernel again into the video networking data packet, and sending the video networking data packet to the video networking Modem.
