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.

Example one

The communication system of the embodiment of the invention can comprise a video networking terminal and a gateway device, wherein the video networking terminal is in a non-video networking environment. The non-video networking environment may be an Internet environment, such as an IP (Internet Protocol ) network.

The embodiment of the invention mainly solves the technical problem of how to realize the communication of the video networking terminal in the non-video networking environment. By arranging the gateway equipment, the gateway equipment can realize protocol conversion between the video networking protocol and the Internet protocol, thereby realizing the fusion of the video networking and the Internet.

The video network terminal can be various conference set-top boxes, video telephone set-top boxes, operation teaching set-top boxes and the like. The gateway device may be a VPN-Hub (Virtual Private Network-Hub, VHub for short), a CPE (Customer Premise Equipment), or the like.

Referring to fig. 5, a flowchart illustrating steps of a communication method according to a first embodiment of the present invention is shown.

The communication method of the embodiment of the invention can comprise the following steps:

step 501, if receiving a first video networking message sent by the video networking terminal, the gateway device adds first socket information to the first video networking message to obtain a first internet message, and sends the first internet message through the internet.

The gateway equipment is directly connected with the video networking terminal through a network cable, and the video networking terminal can send a first video networking message to the gateway equipment. Because the gateway device accesses the internet, the gateway device converts the first video network message into a first internet message, and then sends the first internet message out through the internet. Therefore, the purpose of sending the video networking message of the video networking terminal through the Internet is achieved.

In an alternative embodiment, the gateway device may communicate in the internet in a socket manner. Thus, the step of the gateway device converting the first video network message into the first internet message may comprise: and adding first socket information to the first video network message to obtain the first internet message. The first socket information may include an IP address and a port number of a target device to which the gateway device is to send the first internet packet, and the first internet packet may be transmitted to the target device as a payload in the first internet packet according to the IP address and the port number of the target device.

Step 502, if the gateway device receives a second internet message from the internet, deleting second socket information in the second internet message to obtain a second video networking message, and sending the second video networking message to the video networking terminal.

If the device in the internet wants to send the second internet message to the video network terminal, the device firstly sends the first internet message to the gateway device connected with the video network terminal based on the internet. If the gateway equipment receives a second internet message from the internet, the gateway equipment converts the second internet message into a second video network message and then sends the second video network message to the video network terminal. Therefore, the purpose of sending the video networking message carried in the Internet message from the Internet to the video networking terminal is achieved.

In an alternative embodiment, the device in the internet may send the second internet message to the gateway device through a socket. Thus, the step of the gateway device converting the second internet message to the second video network message may comprise: and deleting the second socket information in the second Internet message to obtain a second video networking message. The second socket information may include an IP address and a port number of the gateway device, and the device in the internet may transmit the second internet packet carrying the second video packet as a load to the gateway device according to the IP address and the port number of the gateway device.

In the embodiment of the invention, the protocol conversion between the Internet and the video network is carried out through the gateway equipment, so that the video network terminal in a non-video network environment can also communicate through the Internet, the limitation of the video network terminal is reduced, and the application range of the video network terminal is widened.

Example two

In the video network, various video network services are uniformly managed by a video network server. Various devices for carrying out the video network service are registered in the video network server to carry out normal service. After the successful registration, the video network server allocates information such as a video network number, a Media Access Control (MAC) address, and the like to the registered device. The internet of view server itself also has an internet of view MAC address.

In the embodiment of the invention, in order to enable the video network terminal to access the video network server in the internet environment, the first gateway equipment and the second gateway equipment are arranged between the video network terminal and the video network server. Referring to fig. 6, an architecture diagram of a communication system according to a second embodiment of the present invention is shown. As can be seen from fig. 6, the video networking terminal is connected to the first gateway device, the video networking server is connected to the second gateway device, and both the first gateway device and the second gateway device access the internet. The first gateway device may access the internet through a network cable. The second gateway equipment can access the Internet through the switch, and a firewall is arranged between the switch and the second gateway equipment. The first gateway device and the second gateway device communicate via the internet.

The video network terminal, the first gateway equipment and the second gateway equipment can be registered in a video network server, and the video network server distributes information such as a video network number and a video network MAC address for the registered video network terminal, first gateway equipment and second gateway equipment. The first gateway device is used as the gateway device of the client, and the second gateway device is used as the gateway device of the server.

Referring to fig. 7, a flowchart illustrating steps of a communication method according to a second embodiment of the present invention is shown.

step 701, if the first gateway device receives a first video networking message sent by the video networking terminal, adding first socket information to the first video networking message to obtain a first internet message, and sending the first internet message to the second gateway device through the internet.

The first gateway equipment is directly connected with the video networking terminal through a network cable, and the video networking terminal can send a first video networking message to the first gateway equipment. Since the first gateway device communicates with the second gateway device via the internet, the first gateway device converts the first video network packet into a first internet packet, and then sends the first internet packet to the second gateway device via the internet.

In an alternative embodiment, the first gateway device and the second gateway device may communicate with each other through a socket. Thus, the step of converting the first video network message to a first internet message may comprise: and adding first socket information to the first video network message to obtain the first internet message. The first socket information comprises an IP address and a port number of the second gateway device, and the first video network message can be transmitted to the second gateway device as a load according to the IP address and the port number of the second gateway device.

Step 702, if the second gateway device receives the first internet message, deleting the first socket information in the first internet message to obtain the first video network message, and sending the first video network message to the video network server.

The second gateway device may receive the first internet packet sent by the first gateway device via the internet. The second gateway device communicates with the video network server through the video network, so that the second gateway device also converts the first internet message into the first video network message again, and then sends the first video network message to the video network server through the video network.

In an alternative embodiment, the step of converting the first internet message into the first video internet message may comprise: and deleting the first socket information in the first internet message to obtain the first video internet message.

Steps

701 and 702 enable communication from the video network terminal to the video network server.

Step 703, if the second gateway device receives a second video networking message sent by the video networking server, adding second socket information to the second video networking message to obtain a second internet message, and sending the second internet message to the first gateway device through the internet.

The second gateway device may send the second video networking message to the video networking server. Since the second gateway device communicates with the first gateway device via the internet, the second gateway device converts the second video network packet into a second internet packet, and then sends the second internet packet to the first gateway device via the internet.

A first port listening thread may be created in the first gateway device, which may be used to listen to the first video networking port and the first internet port. The first gateway device may create a first port listening thread upon startup.

The first gateway equipment initializes the first port listening thread. The step of initializing may include: configuring an IP address and a port number of the second gateway device for the first Internet port; and configuring the MAC address and the port number of the video network terminal aiming at the first video network port. The first gateway device communicates with the second gateway device through the first internet port based on the internet, and thus configures an IP address and a port number of the second gateway device for the first internet port. The first gateway device communicates with the video network terminal through the first video network port, and therefore the video network MAC address and port number of the video network terminal are configured for the first video network port.

Step 802, the second gateway device creates a second port listening thread and initializes the second port listening thread.

The second gateway device includes two network ports, a second video networking port and a second internet port, respectively. The second gateway device communicates with the video networking server through a second video networking port and is connected to the internet through a second internet port.

A second port listening thread may be created in the second gateway device, which may be used to listen to the second video networking port and the second internet port. The second gateway device may create a second port listening thread upon startup.

And the second gateway equipment initializes the second port monitoring thread. The step of initializing may include: configuring, for the second video networking port, a video networking MAC address and port number of the video networking server. The second gateway device communicates with the first gateway device through a second internet port based on the internet, the first gateway device belongs to the client, and the second gateway device belongs to the server, so that the first gateway device is actively connected with the second gateway device, and the second gateway device does not need to configure the IP address and the port number of the first gateway device in advance. The second gateway device communicates with the video networking server through the second video networking port, thus configuring the video networking server's video networking MAC address and port number for the second video networking port.

The execution sequence of the

above steps

801 and 802 is not limited in the embodiment of the present invention.

Step 803, the first gateway device starts the first port monitoring thread, and monitors that the first video network port receives the video network messages, and the first internet port receives the internet messages.

The first gateway device may start the first port listening thread after creating the first port listening thread, may also start the first port listening thread after detecting connection with the video networking terminal, and so on. The first port monitoring thread can monitor whether the first video network port receives the video network message and whether the first internet port receives the internet message respectively.

Step 804, the second gateway device starts the second port monitoring thread, and monitors that the second video networking port receives the video networking message, and the second internet port receives the internet message.

The second gateway device may start the second port listening thread after creating the second port listening thread, may start the second port listening thread after detecting a connection with the video networking server, and so on. The second port listening thread may listen to whether the second video network port receives the video network packet and whether the second internet port receives the internet packet, respectively.

In the embodiment of the present invention, the execution sequence of the step 803 and the step 804 is not limited.

Step 805, if the first gateway device monitors that the first video networking port receives the first video networking message sent by the video networking terminal, the first gateway device adds first socket information to the first video networking message to obtain a first internet message, and sends the first internet message to the second gateway device through the first internet port based on the internet.

When the video network terminal wants to send data to the video network server, the data may be encapsulated into a first video network message based on a video network protocol, and the first video network message is sent to a first video network port of the first gateway device. The first video network message may carry a video network MAC address of the video network server, indicating that the first video network message is a video network message to be sent to the video network server.

After receiving the first video network message, the first video network port of the first gateway device puts the first video network message into a ring queue corresponding to the first port monitoring thread. If the first port monitoring thread monitors that the first video networking port receives the first video networking message sent by the video networking terminal, namely the first video networking message exists in the annular queue, the first video networking message is taken out of the annular queue, and first socket information is added to the first video networking message to obtain the first internet message. The first gateway device sends the first internet message to the second gateway device through the first internet port based on the internet.

Step 806, if the second gateway device monitors that the second internet port receives the first internet message, the second gateway device deletes the first socket information in the first internet message to obtain the first video network message, and sends the first video network message to the video network server through the second video network port.

And after receiving the first internet message, the second internet port of the second gateway equipment is put into the annular queue corresponding to the second port monitoring thread. And if the second port monitoring thread monitors that the second internet port receives the first internet message, namely the first internet message exists in the ring queue, the second port monitoring thread takes out the first internet message from the ring queue, deletes the first socket information in the first internet message, and obtains the first video network message. And the second gateway equipment sends the first video networking message to the video networking server through the second video networking port.

In an optional implementation manner, before the first video network message is sent to the video network server, the first video network message may be further analyzed, whether the first video network message carries a video network MAC address of the video network server is determined, and if the first video network message carries the video network MAC address of the video network server, it is determined that the first video network message is the video network message to be sent to the video network server. Therefore, when the first video networking message is judged to carry the video networking MAC address of the video networking server, the first video networking message is sent to the video networking server. Otherwise, filtering out the first video network message.

In step 807, if the second gateway device monitors that the second video networking port receives the second video networking message sent by the video networking server, the second gateway device adds second socket information to the second video networking message to obtain a second internet message, and sends the second internet message to the first gateway device through the second internet port based on the internet.

When the video network server wants to send data to the video network terminal, the data may be encapsulated into a second video network message based on the video network protocol, and the second video network message is sent to a second video network port of the second gateway device. The second video network message may carry the video network MAC address of the video network terminal, indicating that the second video network message is a video network message to be sent to the video network terminal.

And after receiving the second video network message, the second video network port of the second gateway device is placed into the ring queue corresponding to the second port monitoring thread. And if the second port monitoring thread monitors that the second video networking port receives a second video networking message sent by the video networking server, namely the second video networking message exists in the annular queue, the second video networking message is taken out of the annular queue, and second socket information is added to the second video networking message to obtain the second internet message. And the second gateway equipment transmits the second internet message to the first gateway equipment through the second internet port based on the internet.

Step 808, if the first gateway device monitors that the first internet port receives the second internet message, deleting the second socket information in the second internet message to obtain the second video networking message, and sending the second video networking message to the video networking terminal through the first video networking port.

And after receiving the second internet message, the first internet port of the first gateway equipment is placed into the annular queue corresponding to the first port monitoring thread. And if the first port monitoring thread monitors that the first internet port receives the second internet message, namely the second internet message exists in the annular queue, the first port monitoring thread takes out the second internet message from the annular queue, deletes the second socket information in the second internet message, and obtains the second video networking message. And the first gateway equipment sends the second video networking message to the video networking terminal through the first video networking port.

In an optional implementation manner, before the second video network message is sent to the video network terminal, the second video network message may be further analyzed, whether the second video network message carries the video network MAC address of the video network terminal is determined, and if the second video network message carries the video network MAC address of the video network terminal, it is determined that the second video network message is the video network message to be sent to the video network terminal. Therefore, when the second video network message is judged to carry the video network MAC address of the video network terminal, the second video network message is sent to the video network terminal. Otherwise, filtering out the second video network message.

Step 809, when the first gateway device is restarted, releasing the first port listening thread.

The first gateway device needs to be restarted when a problem occurs or the user reconfigures. The first port listening thread may be released upon restart.

Step 810, when the second gateway device is restarted, releasing the second port listening thread.

The second gateway device needs to be restarted after a problem occurs. The second port listening thread may be released upon restart.
