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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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.

Based on the above characteristics of the video network, the data processing scheme provided by the embodiment of the invention follows the protocol of the video network, and simplifies the processing process of fusing IP network services into the video network.

An internet of view server and an internet of view gateway device are arranged in the internet of view. The video network server can be used as a master server to control various services in the video network. The video network gateway equipment is registered in the video network server, and can be accessed to the video network server after registration. The video networking gateway device may include at least one virtual terminal, and the registered video networking server may allocate information such as a Media Access Control (MAC) address and a video networking number to the virtual terminal in the video networking gateway device. The video networking gateway device may interact with the video networking server through a V2V interface. The video networking gateway device may be a video networking Modem.

A storage gateway and an Internet client are arranged in the Internet. If the storage gateway needs to be accessed into the video network, the storage gateway needs to be accessed through the video network gateway device, namely the storage gateway is connected with the video network gateway device, and the video network gateway device is connected with the video network server. However, the network nodes arranged in this way are more, and the data processing process is complex. Therefore, the embodiment of the invention integrates the video networking gateway component in the storage gateway, and the video networking gateway component can realize the corresponding functions of data forwarding and the like of the video networking gateway equipment, so that the video networking gateway equipment does not need to be arranged in a matching way. The video network gateway component of the storage gateway is registered in the video network server, and the video network server can be accessed after the registration. At least one virtual terminal can be included in the video networking gateway component, and the video networking server after registration can allocate information such as a video networking MAC address and a video networking number to the virtual terminal in the video networking gateway component. The video networking gateway component may interact with the video networking server through a V2V interface. The video networking gateway component can be a video networking Modem component. The internet client may be client software installed on a PC (personal computer), a mobile phone, a tablet computer, or the like, and is used for logging in the storage gateway and accessing data of the storage gateway. The storage gateway can be a network disk server and the like, and the network disk server is a video network data storage network disk system.

In an implementation, the following problems are to be solved: 1. and migrating the code of the video networking gateway equipment to the storage gateway. 2. And (4) adaptation and flow modification of a Linux protocol stack. 3. And the original service access logic of the storage gateway is compatible with the logic of data forwarding and the like of the video networking gateway equipment. In the embodiment of the invention, the storage gateway and the video networking gateway equipment both use a Linux operating system, and can realize the integration of programs. The related program of the video networking gateway equipment is installed and started on the storage gateway in an independent component mode, the related program is independent of the original application program of the storage gateway, and the reference of the video networking gateway equipment runs on the storage gateway in an application mode. Therefore, the corresponding functions of data forwarding and the like of the video networking gateway device can be integrated into the Linux kernel layer of the storage gateway to be used as a video networking gateway component.

Example one

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

The data processing method of the embodiment of the invention can comprise the following steps:

step 501, when receiving a first video network packet carrying a first IP data packet sent by the video network server, a video network gateway component performs protocol conversion on the first video network packet carrying the first IP data packet to obtain the first IP data packet.

The video networking gateway component and the video networking server are in bidirectional interaction based on a video networking protocol, and video networking messages are interacted between the video networking gateway component and the video networking server.

If the video network gateway component receives a first video network message which is sent by a video network server and bears a first IP data message, the video network gateway component can determine that the first IP data message borne in the first video network message needs to perform a subsequent IP service processing process. Therefore, the video network gateway component can perform protocol conversion on the first video network message carrying the first IP data message to obtain the first IP data message.

In an alternative embodiment, it is contemplated that the video network messages sent by the video network server to the video network gateway component may be video network messages carrying IP data messages, or may be other types of video network messages, such as video network protocol messages. Therefore, when the video network gateway component receives the first video network packet carrying the first IP data packet sent by the video network server, before performing protocol conversion on the first video network packet carrying the first IP data packet to obtain the first IP data packet, the method may further include: when receiving a first video networking message sent by the video networking server, the video networking gateway component judges whether the first video networking message is a first video networking message bearing a first IP data message; and if so, determining to receive a first video network message which is sent by the video network server and bears a first IP data message.

The IP data packet may include an IP header and a data segment. The video network message carrying the IP data message is a message transmitted in a video network link and consists of a video network packet header and a message carrying data segment. The video network packet header refers to the header of the video network message and contains information such as a video network MAC address and a video network protocol. The data section of the bearer message is a data area for bearing an IP data message in the video networking message.

In an optional implementation, the step of determining whether the first video network packet is a first video network packet carrying a first IP data packet may include: the video network gateway component extracts a field of a representation type from a video network packet header of the first video network message according to a preset video network packet header structure; and judging whether the type corresponding to the extracted field is the type of the IP data bearing message or not according to the corresponding relation between the preset field and the type, and if the type is the type of the IP data bearing message, determining that the first video network message is the first video network message bearing the first IP data message.

For example, a field with field number 0 in the video network packet header may be preset as a field for indicating the transmission direction, a field with field number 1 may be preset as a field for indicating the type, and so on. The corresponding relationship between the field representing the type and the type is preset, for example, when the field is set to be 0x0001, the corresponding type is a video networking protocol message type, when the field is set to be 0x0002, the corresponding type is a video networking service message type, when the field is set to be 0x0003, the corresponding type is a bearer IP data message type, and the like. Therefore, when receiving the first video network message, the video network gateway component extracts a field with a field number of 1 from the first video network message, for example, the extracted field is 0x0003, and obtains that the type corresponding to 0x0003 is the type of the bearer IP data message according to the correspondence between the field and the type, so that it can be determined that the type of the first video network message is the first video network message bearing the first IP data message.

The video networking gateway component may further include a gateway signaling layer, and if it is determined that the first video networking message is a video networking protocol message, such as a heartbeat message, the video networking gateway component may transmit the first video networking message to the gateway signaling layer for related processing.

Step 502, the video network gateway component transmits the first IP data packet to a protocol stack corresponding to the storage gateway.

The storage gateway corresponds to a protocol stack. The protocol stack is the sum of each layer protocol in the network, and the image reflects the process of file transmission in the network: from the upper layer protocol to the bottom layer protocol, and then from the bottom layer protocol to the upper layer protocol. After the first IP data packet is obtained through conversion, the video networking gateway component may transmit the first IP data packet to the Linux protocol stack corresponding to the storage gateway, so as to perform a subsequent processing process for the IP data packet. For example, if the IP data packet is a packet requesting to store data, the IP data packet is stored to a corresponding location; and if the IP data message is a message requesting to download the data, acquiring the data to be downloaded, returning the data to be downloaded, and the like.

Step 503, when intercepting the second IP data packet returned by the protocol stack corresponding to the storage gateway, the video networking gateway component performs protocol conversion on the second IP data packet to obtain a second video networking packet carrying the second IP data packet.

And if the protocol stack corresponding to the storage gateway returns the second IP data message, the video networking gateway component can intercept the second IP data message returned by the protocol stack corresponding to the storage gateway. The video network gateway component, if intercepting the second IP data packet, may determine that the second IP data packet is subsequently to be sent to the video network server. Therefore, the video network gateway component can perform protocol conversion on the second IP data packet to obtain a second video network packet carrying the second IP data packet.

Step 504, the video network gateway component sends the second video network message carrying the second IP data message to the video network server.

After the second video network message carrying the second IP data message is obtained through conversion, the video network gateway component may send the second video network message carrying the second IP data message to the video network server, so as to perform a subsequent processing procedure for the second video network message carrying the second IP data message. For example, the video network server sends a second video network packet carrying the second IP data packet to the video network gateway device connected to the internet client requesting the second IP data packet, and so on.

In the embodiment of the invention, the service of fusing the storage gateway in the video network can be realized through the video network gateway component, and the video network gateway component is integrated on the storage gateway, so that the storage gateway can interact with the video network server through the video network gateway component, and video network gateway equipment does not need to be separately arranged between the storage gateway and the video network server, thereby reducing the number of network nodes, simplifying the data processing process, having higher data security and saving the cost.

Example two

Referring to fig. 6, a flowchart illustrating steps of a data processing method according to a second embodiment of the present invention is shown.

step 601, when receiving a first IP data packet sent by the internet client, the video networking gateway device performs protocol conversion on the first IP data packet to obtain a first video networking packet bearing the first IP data packet.

The internet client and the video network gateway equipment perform bidirectional interaction based on an internet protocol, and the interaction between the internet client and the video network gateway equipment is an IP data message.

The internet client may generate a first IP datagram, for example, the first IP datagram may be a datagram requesting to store data or a datagram requesting to download data, and the internet client sends the first IP datagram to the internet gateway device through the internet.

The video network gateway device can determine that the first IP data message is to be sent to the video network server subsequently if receiving the first IP data message sent by the Internet client. Therefore, the video network gateway device can perform protocol conversion on the first IP data message to obtain a first video network message bearing the first IP data message.

The step of performing protocol conversion on the first IP data packet to obtain a first video network packet carrying the first IP data packet may include: the video network gateway equipment encapsulates the first IP data message and adds the first IP data message to a first bearer message data segment; and adding a first video network packet header to the first bearer message data segment to obtain a first video network message bearing the first IP data message. The first packet header may include, among other things, the video network MAC address (as a source address) of the virtual terminal in the video network gateway device for processing the first IP datagram, the video network MAC address (as a destination address) of the video network server, video network protocol information, and so on.

Step 602, the gateway device of the video network sends the first video network packet carrying the first IP data packet to the video network server.

The video network gateway device sends a first video network message bearing the first IP data message to a video network server through a video network by using a virtual terminal for processing the first IP data message.

Step 603, the video network server forwards the first video network packet carrying the first IP data packet to the video network gateway component according to the downlink communication link configured for the video network gateway component.

The corresponding relationship between the virtual terminal in the video network gateway component and the virtual terminal in the video network gateway device, such as the corresponding relationship between the video network MAC address and the port information, may be stored in the video network server. The video networking server may determine, from the correspondence, related information such as a video networking MAC address, port information, and the like of a virtual terminal used for processing the first IP data packet in the corresponding video networking gateway component according to the related information in the first video networking packet, such as the video networking MAC address of the virtual terminal used for processing the first IP data packet in the video networking gateway device.

The video network server can configure a downlink communication link for the video network gateway component according to the determined related information of the video network gateway component, and forward the first video network packet carrying the first IP data packet to the video network gateway component through the downlink communication link.

In practical applications, the video network is a network with a centralized control function, and includes a master control server (such as a video network server) and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is to configure a table by notifying a switching device of a downlink communication link for a current service by the master control server, and then perform packet transmission based on the configured table.

Namely, the communication method in the video network includes:

and the master control server configures the downlink communication link of the current service.

And transmitting the data packet of the current service sent by the source terminal to the target terminal according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: and informing the switching equipment related to the downlink communication link of the current service to allocate the table.

Further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As mentioned above, the video network includes an access network portion, in which the master server is a node server and the lower-level network devices include an access switch and a terminal.

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

and a substep S11, the main control server obtains the downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes the downlink communication port information of the main control server and the access switch participating in the current service.

In the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the main control server; and sending a port configuration command to the corresponding access switch according to the downlink communication port information of the access switch.

In sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For a multicast communication service (e.g., video conference) in the access network, the step of the master server obtaining downlink information of the current service may include the following sub-steps:

in sub-step S21, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, where the service request protocol packet includes service type information, service content information, and an access network address of the target terminal.

Wherein, the service content information includes a service number.

And a substep S22, the main control server extracts the access network address of the source terminal in a preset content-address mapping table according to the service number.

In the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

Step 604, when receiving a first video network packet carrying a first IP data packet sent by the video network server, the video network gateway component performs protocol conversion on the first video network packet carrying the first IP data packet to obtain the first IP data packet.

The step of performing protocol conversion on the first video network packet carrying the first IP data packet to obtain the first IP data packet may include: the video network gateway component decapsulates the first video network message carrying the first IP data message to obtain a first video network packet header and a first carrier message data segment; and acquiring the first IP data message from the first bearer message data segment.

Step 605, the video networking gateway component transmits the first IP data packet to the protocol stack corresponding to the storage gateway.

Step 606, when intercepting the second IP data packet returned by the protocol stack corresponding to the storage gateway, the video networking gateway component performs protocol conversion on the second IP data packet to obtain a second video networking packet bearing the second IP data packet.

The step of performing protocol conversion on the second IP data packet to obtain a second video network packet carrying the second IP data packet may include: the video networking gateway component encapsulates the second IP data message and adds the second IP data message to a second bearer message data segment; and the video network gateway component adds a second video network packet header to the second bearer message data segment to obtain a second video network message bearing the second IP data message.

The second packet header may include, among other things, the video network MAC address of the virtual terminal in the video network gateway component for processing the second IP datagram (as the source address), the video network MAC address of the video network server (as the destination address), the video network protocol information, and so on.

And the video network gateway component transmits a second video network message bearing the second IP data message to a video network server by using the virtual terminal for processing the second IP data message through the video network.

Step 608, the video network server forwards the second video network packet carrying the second IP data packet to the video network gateway device according to the downlink communication link configured for the video network gateway device.

The video network server may determine, from the correspondence, information such as a video network MAC address and port information of a virtual terminal used for processing the second IP data packet in the corresponding video network gateway device according to related information in the second video network packet, such as a video network MAC address of a virtual terminal used for processing the second IP data packet in the video network gateway component.

The video network server can configure a downlink communication link for the video network gateway device according to the determined related information of the video network gateway device, and forward a second video network packet carrying the second IP data packet to the video network gateway device through the downlink communication link.

Step 609, the video network gateway device performs protocol conversion on the second video network message carrying the second IP data message to obtain the second IP data message.

If the video network gateway device receives a second video network message carrying a second IP data message, the video network gateway device can determine that the second IP data message is to be sent to the Internet client subsequently. Therefore, the video network gateway device performs protocol conversion on the second video network message carrying the second IP data message to obtain the second IP data message.
