Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 2 and fig. 3, fig. 2 is a flowchart illustrating steps of an embodiment of a data forwarding method of the present invention, the method is applied to a video network router, fig. 3 is a schematic structural diagram of the video network router when in use, the video network router includes a video network port 31, a data forwarding module 32, a virtual switch module 35, at least one data service port 33, and at least one dedicated terminal port 36; the solid lines in fig. 3 represent the transmission paths of the video networking messages, and the dotted lines represent the transmission paths of the IP messages. The method specifically comprises the following steps:
In this embodiment, the video network port is a physical interface disposed on the video network router, and is used for connecting a video network link and establishing a connection with the video network. An internet of view router receives an internet of view message via an internet of view interface, and it is understood that the internet of view message is a data packet based on an internet of view protocol (e.g., V2V protocol), and the internet of view message may be composed of an internet of view protocol header + a data packet segment, wherein the data packet segment may be used to carry a video/audio message or an IP message, and the IP message is a data packet based on an internet protocol (e.g., TCP/IP network protocol).
In this embodiment, the video network packet carries a destination MAC Address (Media Access Control Address), which may also be referred to as a physical Address and a hardware Address, and is used to define a location of the terminal device in the network. In the physical transmission process of the network bottom layer, data transmission is realized by identifying a host through a MAC address. The destination MAC address may be the MAC address of the target terminal. And the video networking message sent to the target terminal needs to carry the destination MAC address.
The video network MAC corresponding table can be a preset MAC corresponding table of the video network port, and the incidence relation between the MAC address and the data service port is stored in the video network MAC corresponding table. And after receiving the video networking message, the video networking port extracts the destination MAC address carried by the video networking message and judges whether the destination MAC address of the video networking message is in a preset video networking MAC corresponding table or not.
And 203, if the destination MAC address of the video networking message is in the video networking MAC corresponding table, sending the video networking message to the data forwarding module.
In the embodiment of the invention, the data forwarding module is arranged in the video network router, and the video network port is connected with the data forwarding module, so that the video network message received by the video network port can be sent to the data forwarding module, and the data forwarding module can further process the video network message. When the destination MAC address of the video network message is in the video network MAC corresponding table, the video network message is used by the upper layer service of the video network router, and therefore the video network message is sent to the data forwarding module. It will be appreciated that the data message segment of the video network message is used to carry IP messages.
And step 204, the data forwarding module converts the video networking message into a corresponding IP message and then sends the IP message to a target data service port.
In the embodiment of the invention, the data forwarding module is connected with the data service port, and the data service port is a physical interface arranged on the video networking router and is used for being connected with the Internet terminal. The internet terminal is a terminal device in the internet, which communicates by using an internet protocol, and includes a PC (Personal Computer), a mobile terminal, and the like, and various applications can be run on the terminal device. Because the internet terminal can only receive and process the IP message. Therefore, the data forwarding module needs to convert the received video networking message into a corresponding IP message and send the IP message to the target data service port.
The data forwarding module is connected with all data service ports, and the video networking router is generally provided with at least one data service port, so that a target data service port needs to be determined from the at least one data service port. In a specific example, the step of converting, by the data forwarding module, the video networking packet into a corresponding IP packet and then sending the IP packet to a target data service port includes:
and the data forwarding module determines a target data service port according to the video network MAC corresponding table, converts the video network message into a corresponding IP message and then sends the IP message to the target data service port.
And the data forwarding module determines a target data service port from the plurality of data service ports according to the incidence relation between the MAC address and the data service port in the MAC corresponding table of the video network so as to directly send the converted IP message to the target data service port, thereby improving the accuracy and the efficiency of data transmission.
Further, the data forwarding module includes an IP protocol forwarding table, and the step of the data forwarding module converting the video network packet into a corresponding IP packet and then sending the IP packet to the target data service port includes:
the data forwarding module analyzes the video network message according to the IP protocol forwarding table to generate a corresponding target IP message;
and the data forwarding module sends the target IP message to the target data service port.
In the embodiment of the invention, the IP protocol forwarding table can be preset in the data forwarding module, and the IP protocol forwarding table is a data table comprising a protocol conversion function. Because the communication protocols adopted by the video network terminal and the internet terminal are different, in order to realize communication between the video network terminal and the internet terminal, after the data forwarding module receives the video network message, the video network message is analyzed according to the IP protocol forwarding table, and a corresponding target IP message is generated. The specific parsing process may be to remove a video networking protocol header of the video networking message, so as to obtain a corresponding target IP message.
Further, since the length of the IP packet is between 64-1514 bytes, and the maximum length of the datagram segments in the video network packet is 1024 bytes, when the length of the IP packet is greater than 1024 bytes, the video network packet needs to be fragmented and converted into the video network packet, that is, when a video network port receives one video network packet, the video network packet may be a fragmented packet. Therefore, the step of the data forwarding module analyzing the video network message according to the IP protocol forwarding table to generate a corresponding target IP message further includes:
the data forwarding module judges whether the video network message is a fragment message;
if so, the data forwarding module analyzes the video networking message according to the IP protocol forwarding table to generate a corresponding initial IP message;
the data forwarding module recombines the initial IP messages which are the fragment messages to form the target IP message.
In the embodiment of the invention, the head of the video networking protocol of the video networking message comprises a first field, a second field and a third field, wherein the first field is used for representing the identity serial number of the video networking message, belongs to the video networking fragment message obtained by packaging the same IP message and has the same identity serial number; the second field is used to indicate whether the video network packet is a fragment packet, for example, 0 may be used to indicate that the video network packet is not a fragment packet, and 1 is used to indicate that the video network packet is a fragment packet; the third field is used for indicating the number of the pieces to which the video network message belongs, for example, when the video network message belongs to the first piece of message of the fragment messages, the third field is 1; when the video network message belongs to the second message of the fragment messages, the third field is 2.
The data forwarding module can judge whether the video networking message is a fragment message according to the video networking protocol header of the received video networking message, if the video networking message is the fragment message, the video networking message is analyzed according to an IP protocol forwarding table to generate a corresponding initial IP message, and the initial IP message is put into a cache; then, the initial IP messages which are mutually fragmented messages are recombined to form a target IP message. Specifically, when two initial IP packets obtained by analyzing the video network packets with the same identity serial number are stored in the cache, the data forwarding module recombines the two initial IP packets to form a target IP packet according to the number of the initial IP packets. Otherwise, if the video networking message is not a fragment message, the video networking message is directly analyzed to obtain a corresponding target IP message.
In the embodiment of the invention, the virtual switch module is arranged in the video network router and is connected with the video network port, so that the video network message received by the video network port can be sent to the virtual switch module, and the virtual switch module can further process the video network message. When the destination MAC address of the video networking message is not in the video networking MAC mapping table, the video networking message is indicated to be used by the video networking terminal device, and the video networking message can be sent to the virtual switch module, so that the downstream port device performs video networking service.
In a specific implementation, since the video networking port is a physical interface and cannot be directly connected to the virtual switch module, as shown in fig. 3, a virtual interface 34 needs to be provided between the video networking port and the virtual switch module. The step of sending the video networking message to the virtual switch module if the destination MAC address of the video networking message is not in the video networking MAC correspondence table includes:
and if the destination MAC address of the video networking message is not in the video networking MAC corresponding table, sending the video networking message to the virtual switch module through the virtual interface.
Specifically, the video networking port modifies the source port of the video networking message into the virtual interface and sends the modified video networking message to the virtual switch module.
In the embodiment of the invention, the virtual switch module is connected with the special terminal port, and the special terminal port is a physical interface arranged on the video network router and is used for being connected with the video network terminal. The video network terminal is a terminal device in the video network, adopts a video network protocol to carry out communication, and comprises a video network camera, a video network monitoring access server, a streaming media gateway server and the like. Because the video network terminal can directly receive and process the video network message, the virtual switch module can directly send the received video network message to a target special terminal port in the special terminal ports.
In a specific example, the step of the virtual switch module sending the video networking packet to the destination dedicated terminal port includes:
when the destination MAC address of the video networking message is in the MAC address learning table, the virtual switch module determines a target special terminal port according to the MAC address learning table and sends the video networking message to the target special terminal port;
and when the destination MAC address of the video networking message is not in the MAC address learning table, the virtual switch module sends the video networking message to all special terminal ports connected with the virtual switch module.
In the embodiment of the invention, the association relation between the MAC address and the special terminal port is stored in the MAC address learning table of the virtual switch module; specifically, the virtual switch module learns a dedicated terminal port associated with the destination MAC address, and stores the association relationship between the destination MAC address and the dedicated terminal port in the MAC address learning table. After receiving the video networking message, the virtual switch module extracts a destination MAC address of the video networking message, judges whether the destination MAC address is in an MAC address learning table or not, determines a target special terminal port according to the association relation between the MAC address stored in the MAC address learning table and the special terminal port if the destination MAC address of the video networking message is in the MAC address learning table, and transmits the video networking message to the target special terminal port after determining the target special terminal port so as to facilitate the video networking service of a video networking terminal connected with the target special terminal port. On the contrary, if the destination MAC address of the video networking message is not in the MAC address learning table, the virtual switch module cannot determine the destination dedicated terminal port, and therefore the virtual switch module sends the video networking message in a broadcast manner, that is, the virtual switch module sends the video networking message to all the dedicated terminal ports connected to the virtual switch module.
Further, in an example, after the step of sending, by the virtual switch module, the video networking packet to all the dedicated terminal ports connected to the virtual switch module when the destination MAC address of the video networking packet is not in the MAC address learning table, the method further includes:
the virtual switch module receives a response message returned aiming at the video networking message, and the response message is sent out by the target special terminal port;
and the virtual switch module stores the association relation between the destination MAC address of the video networking message and the destination special terminal port into the MAC address learning table.
In a specific implementation, when the virtual switch module sends the video networking message in a broadcast manner, only the target dedicated terminal port returns a response message to the video networking message, and the response message includes a port number or an address of the target dedicated terminal port. The virtual switch module acquires the port number or address of the target special terminal port according to the received response message, establishes the incidence relation between the target MAC address of the video networking message and the target special terminal port, and stores the incidence relation into an MAC address learning table. When the virtual switch module receives the video networking message of the target MAC address again, the target special terminal port can be determined from the MAC address learning table, and the video networking message is forwarded in a unicast mode, namely, the video networking message is directly sent to the target special terminal port, so that the accuracy and the efficiency of data transmission are improved.

In the figure, the dotted line arrow part represents the transmission flow of the IP packet corresponding to the video network packet, and the solid line arrow part represents the transmission flow of the video network packet.
The embodiment of the invention is applied to a router of the video networking, and the router of the video networking comprises a video networking port, a data forwarding module, a virtual switch module, at least one data service port and at least one special terminal port; receiving the video networking message through the video networking port, and judging whether a target MAC address of the video networking message is in a video networking MAC corresponding table preset by the video networking port or not; if the destination MAC address of the video networking message is in the video networking MAC corresponding table, the video networking message is sent to a data forwarding module; the data forwarding module converts the video networking message into a corresponding IP message and then sends the IP message to a target data service port; if the destination MAC address of the video networking message is not in the video networking MAC corresponding table, the video networking message is sent to the virtual switch module; the virtual switch module sends the video networking message to a target special terminal port; in the embodiment of the invention, the video networking router integrates the data forwarding module and the virtual switch module, and the video networking message accessed by one video networking private line is applied to various video networking services, so that network nodes are reduced, and the management and maintenance difficulty of the video networking is reduced.

2. Video networking packet definition
2.1 Access network packet definition

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.
