The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch or directly connected with the node server.

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.

Referring to fig. 5, a flowchart illustrating steps of a method for message processing according to an embodiment of the present invention may be applied to a video network server, and as shown in fig. 6, the video network server may include one or more video network physical interfaces 602 connected to a video network device 601, an internet physical interface 604 connected to an internet device 603, and a virtual interface 605, where one end of the virtual interface may be connected to the video network physical interface, and the other end of the virtual interface may be connected to the internet physical interface through a video network bridge module 606.

As an example, the video network physical interface may be a socket accessing a video network cable for receiving a video network message, the internet physical interface (IP interface) may be a socket accessing an internet network cable for receiving an internet message (IP message), and the virtual interface may be a video network tunnel virtual interface, as shown in fig. 7, and in the video network server, the conversion and transceiving between the video network message and the internet message may be implemented.

Specifically, the method can comprise the following steps:

step 501, the video networking server receives a video networking message sent by the video networking equipment aiming at the internet equipment through the video networking physical interface;

when the video network device sends a message to an internet device, the video network device may determine a physical address of the internet device, generate a video network message for the physical address, where the message may be a three-layer message, and then transmit the message to a video network server through a video network physical interface, so that the video network server receives the video network message.

Step 502, the video network server converts the video network message into an internet message and sends the internet message to the video network bridge module through the virtual interface;

as an example, the bridge-over-video module may include a MAC address table, through which a query of a MAC address may be performed, and a MAC (Media Access Control) address, also called a hardware address, may be used to define a location of the network device, and during a physical transmission process of a network bottom layer, data transmission identifies a host through the physical address.

When the video network server processes the video network message received from the video network physical interface, because the obtained parameter of the video network message has high coupling degree with the parameter of the video network server, if the converted message is directly forwarded, the video network server easily mistakenly regards the required message as the message of the video network server and does not forward the message.

In specific implementation, one or more virtual interfaces can be set in the video network server in advance, one virtual interface can be connected with one video network physical interface, and a message transmitted through the virtual interface can be simulated to be acquired from the virtual interface instead of the video network physical interface, so that the risk that the message is blocked and forwarded by the video network server is reduced, and the forwarding precision of the message is improved.

The message is directly forwarded to the Internet physical interface through the virtual interface without carrying out logic processing on the message content through the protocol stack again, so that transparent transmission of the message is realized, and the process of message transmission is simplified

After the video networking message is acquired through the video networking physical interface, the video networking message can be decoded to generate an internet message, and the internet message is sent to the virtual interface, so that the internet message with the virtual interface identifier is sent to the video networking bridge module through the virtual interface.

In an embodiment of the present invention, the step of converting the video network message into an internet message may include the following sub-steps:

Specifically, the protocol stack entry function may be a function for performing protocol conversion in the protocol stack.

A protocol stack, also called a protocol stack, is a specific software implementation of a computer network protocol suite. Because the communication protocols adopted by the video networking equipment and the internet equipment are different, in order to realize communication between the video networking equipment and the internet equipment, after receiving the video networking message, the video networking server can send the video networking message to the protocol stack so as to call the protocol stack entry function in the protocol stack and convert the video networking message into the internet message.

Step 503, the video network server sends the internet message to the internet physical interface through the video network bridge module, and sends the internet message to the internet device through the internet physical interface.

In practical application, the video network bridge module can associate the internet physical interface with the video network virtual interface, and after the internet message is sent to the video network bridge module, the video network server can search in the video network bridge module, determine the address of the internet physical interface of the internet device receiving the internet message, and send the internet message to the internet physical interface connected with the video network bridge module, so that the internet device receives the message.

In an embodiment of the present invention, the step of sending the internet message to the internet physical interface through the video-networking bridge module may include the following sub-steps:

substep 11, obtaining a target MAC address in the internet message, and traversing an MAC address table in the video bridge module;

in a specific implementation, the video networking bridge module may record MAC addresses of the video networking device or the internet device, and in the MAC address table, the MAC address of the video networking device may correspond to the virtual interface and the video networking physical interface, and the MAC address of the internet device may correspond to the internet physical interface.

For example, a MAC address table may be set in the video bridge module in advance to record a plurality of internet physical interfaces and MAC addresses of internet devices connected to the internet physical interfaces.

After the internet message is generated, the video network server can obtain a target MAC address in the message, determine the specific internet equipment for receiving the internet message, traverse the MAC address table and search the target MAC address.

And a substep 12, when the MAC address table includes the target MAC address, sending the internet message to an internet physical interface corresponding to the target MAC address.

When the MAC address table comprises the target MAC address, the Internet physical interface can be determined, and the Internet message acquired from the virtual interface is sent to the Internet physical interface.

In another embodiment of the present invention, the step of sending the internet message to the internet physical interface through the video bridge module may include the following sub-steps:

substep 21, obtaining a target MAC address in the internet message, and traversing an MAC address table in the video network bridge module;

substep 22, when the MAC address table does not include the target MAC address, learning the target MAC address to obtain the target MAC address;

after traversing the MAC address table in the video bridge module, if the target MAC address is not found, it may be determined that the video bridge module has not previously received the internet packet sent by the internet device corresponding to the target MAC address, and based on this, the target MAC address may be learned to obtain the target MAC address.

Specifically, the video network server may determine a virtual port for transmitting the internet packet, and then send a plurality of test packets including the target MAC address to all ports except the virtual port in the MAC address table.

After receiving the data packet, the target device corresponding to the target MAC address can respond to the test data packet and send a response message to the video network server, and after receiving the response message, the video network server can record the MAC address of the target device in the message, thereby completing the learning of the target MAC address.

When other devices except the target device receive the test data packet, the target MAC address in the test data packet is not consistent with the MAC address of the device itself, and the test data packet may be discarded without responding.

Alternatively, another method may be used to learn the destination MAC address. For example, the video network server may wait for a message uploaded by a target device corresponding to the target MAC address, and after receiving the message from the target MAC address, record the address in the MAC address table in the video network bridge module, thereby completing the learning of the target MAC address.

And a substep 23, after obtaining the target MAC address, sending the internet packet to an internet physical interface corresponding to the target MAC address.

When the MAC address table comprises the target MAC address, the Internet physical interface can be determined, and the video networking server can send the Internet message to the Internet equipment through the Internet physical interface.

In a specific application, as shown in fig. 7, after a video networking message is generated from a video networking device, the video networking message may be sent to a video networking server through a video networking interface, after the video networking message is received, the video networking server may decode the video networking message by using a protocol stack entry function to generate an internet message, and send the internet message to a video networking bridge module (the "video networking bridge module" in fig. 8) through a virtual interface for MAC table lookup, and when a target MAC address in the internet message is found in the MAC table, the internet message may be sent to an internet device through an internet interface associated with the video networking bridge module; when the target MAC address is not found in the MAC table, the target MAC address may be learned ("view bridge forwarding MAC table learning" in fig. 8), and after successfully learning the target MAC address, the learned target MAC address may be sent to the internet device through the internet interface associated with the view bridge module.

Referring to fig. 9, a flowchart illustrating steps of another message processing method according to an embodiment of the present invention is shown, and may be applied to a video network server, where the video network server may include one or more video network physical interfaces connected to a video network device, internet physical interfaces connected to an internet device, and a virtual interface, where one end of the virtual interface may be connected to the video network physical interface, and the other end of the virtual interface may be connected to the internet physical interface through a video network bridge module.

Specifically, the method can comprise the following steps:

step 901, the video networking server receives an internet message sent by the internet equipment aiming at the video networking equipment through the internet physical interface;

when the internet equipment sends a message to the video networking equipment, the message can be sent through the internet physical interface.

For example, the internet device may obtain a physical address of the video networking device, generate an internet message for the physical address, and transmit the internet message to the internet physical interface through the internet network cable after the internet message is generated, so that the video networking server receives the internet message through the internet physical interface.

Step 902, the video network server sends the internet message to the video network bridge module, and sends the internet message to the virtual interface through the video network bridge module;

as an example, the bridge of video networking module may include a MAC address table, and the video networking server may query the MAC address through the bridge of video networking module. The MAC (Media Access Control) address, also called a hardware address, may be used to define the location of the network device, and during the physical transmission process of the network bottom layer, the data transmission identifies the host through the physical address.

In practical application, the video network bridge module can associate the internet physical interface with the video network virtual interface, after receiving an internet message, the video network server can send the internet message to the video network bridge module, search the video network equipment address for receiving the internet message in the video network bridge module, determine the virtual interface, and send the internet message to the virtual interface.

In an embodiment of the present invention, the step of sending the internet message to the virtual interface through the video bridge module may include the following sub-steps:

substep 31, obtaining a target MAC address in the internet message, and traversing an MAC address table in the video bridge module;

in a specific implementation, a MAC address table may be set in the video bridge module in advance to record MAC addresses of one or more video devices, and video physical interfaces and virtual interfaces corresponding to the MAC addresses. For example, if the MAC address of an internet-of-view device is a and the corresponding physical and virtual interfaces are b and c, respectively, after the target MAC address is determined, the corresponding physical and virtual interfaces of the internet-of-view device can be determined.

And a substep 32, when the MAC address table includes the target MAC address, sending the internet packet to a virtual interface corresponding to the target MAC address.

When the target MAC address is included in the MAC address table, the virtual interface and the video network physical interface can be determined, and the video network server can send the Internet message to the virtual interface.

substep 41, obtaining a target MAC address in the internet message, and traversing a MAC address table in the video bridge module;

substep 42, when the MAC address table does not include the target MAC address, learning the target MAC address to obtain the target MAC address;

after traversing the MAC address table in the video bridge module, if the target MAC address is not found, it may be determined that the video bridge module has not received the video network packet sent by the video network device corresponding to the target MAC address before, and based on this, the target MAC address may be learned to obtain the target MAC address of the video network device.

And a substep 43, after obtaining the target MAC address, sending the internet packet to a virtual interface corresponding to the target MAC address.

Step 903, the video network server converts the internet message into a video network message according to the virtual interface;

because the communication protocols adopted by the video network equipment and the internet equipment are different, in order to realize the communication between the video network equipment and the internet equipment, after the internet message is sent to the virtual interface, the internet message can be converted into the video network message according to the video network physical interface mapped by the virtual interface.

In an embodiment of the present invention, the step of converting the internet packet into a video internet packet according to the virtual interface may include the following steps:

determining a packet sending function corresponding to the virtual interface; and converting the internet message into a video networking message through the packet sending function.

As an example, the packaging function may be a function for converting an internet message to an internet-of-view message.

Different virtual interfaces can be mapped to different video networking physical interfaces and physical addresses, in order to enable the internet message received by the virtual interfaces to be sent to the correct physical address, different packet sending functions can be set for the different virtual interfaces in advance, after the internet message is sent to the virtual interfaces, the video networking server can determine the packet sending function of the virtual interfaces and call the packet sending function to convert the internet message into the video networking message.

Step 904, the internet of vision server sends the internet of vision message to the physical interface of the internet of vision through the virtual interface, and sends the internet of vision message to the internet of vision equipment through the physical interface of the internet of vision.

As an example, the video networking physical interface may be a socket that accesses a video networking cable.

In a particular implementation, the video networking device may access the video networking through a video networking physical interface to communicate with other devices in the video networking. After generating the video networking message, the video networking server may send the video networking message to a video networking physical interface connected to the virtual interface via the virtual interface, so that the video networking message may be sent to the video networking device through the video networking physical interface.

In a specific application, as shown in fig. 7, after an internet message ("IP message" in fig. 7) is generated from an internet device, the internet message may be sent to a video bridge module ("video bridge module" in fig. 8) through an internet interface ("IP interface" in fig. 7), an MAC table lookup is performed, when a target MAC address in the internet message is found in the MAC table, a virtual interface associated with the video bridge module may be determined, a packet sending function corresponding to the virtual interface is called, the internet message is converted into the video message, and the video message is sent to the video bridge module through the virtual interface associated with the video bridge module; when the target MAC address is not found in the MAC table, the target MAC address may be learned ("MAC table learning forwarded by the video bridge" in fig. 8), and after the target MAC address is successfully learned, a virtual interface associated with the video bridge module is determined, a packet forwarding function corresponding to the virtual interface is called, the internet message is converted into a video network message, and the video network message is sent to the video network interface through the virtual interface associated with the video bridge module, so that the video network device receives the message.

In the embodiment of the invention, the internet message sent by the internet equipment aiming at the video network equipment is received through the internet physical interface, the internet message is sent to the video network bridge module, the internet message is sent to the virtual interface through the video network bridge module, the internet message is converted into the video network message according to the virtual interface, the video network message is sent to the video network physical interface through the virtual interface and is sent to the video network equipment through the video network physical interface, the video network message is directly sent from the virtual interface to the video network physical interface, the video network message does not need to pass through a protocol stack for many times, the processing steps in message conversion are reduced, and the system overhead is reduced.
