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 flow chart of steps of a data interaction method of an embodiment of the invention is shown.

The data interaction method is applied to a video network system, the video network system comprises a client and a server, wherein the client is provided with a first operating system, the server is provided with a second operating system, the client is a video network client, the server is a video network server, and the operating systems of the client and the server are different.

For the convenience of the reader to understand, the following embodiments take the first operating system as the Windows operating system and the second operating system as the Linux operating system as an example for description.

As shown in fig. 5, the method may include the steps of:

s601, the client sends a file system information request to the server through the video network;

wherein the file system information request includes identification information of a first file directory in a local file system of the server;

the client can request the connected server for the attribute information of the file items (including folders and/or files) belonging to a certain file directory (namely a first file directory) in the local file system of the server corresponding to the Linux operating system of the client through the video network.

The identification information for the first file directory may be information that is previously agreed to identify a certain file directory.

Optionally, S501, in response to the file system information request, the server sends the first file directory and the attribute information of the first file item directly subordinate to the first file directory to the client through a video network;

after receiving the file system information request, the server may send the first file directory corresponding to the identification information and the attribute information of the files and/or folders directly subordinate to the first file directory to the client through the video network.

The first file directory sent to the client may express a directory structure of a certain file directory requested by the client, and the attribute information of the file may include, but is not limited to, a file name, a file size, a file type, a last modification time, and the like; the attribute information of the folder may include, but is not limited to, a folder name, a folder size, and the like.

S602, the client receives the first file directory and the attribute information of the first file item directly subordinate to the first file directory, which are sent by the server through the video network;

s603, the client generates a virtual disk, generates a file view for the received first file directory and the attribute information of the first file item according to the file display mode of the first operating system, and displays the file view in the file management interface of the virtual disk.

In the embodiment of the present invention, in order to display the received attribute information of the first file directory and the file items directly subordinate to the first file directory in the file management interface of the client, a file view conforming to the Windows operating system may be generated by the client, for example, a virtual disk may be generated by the client, and a file view may be generated according to the file display mode of Windows for receiving the first file directory and the attribute information of the first file items, so that the file view includes the first file directory of the server and the attribute information of the first file items directly subordinate to the first file directory. And displaying the file view in a file management interface of the virtual F disk.

In this way, the client can display the first file directory of the file items stored on the server side and the attribute information of the plurality of files and/or folders directly subordinate to the first file directory in a file display manner supported by the local operating system.

For example, the file view is shown in fig. 6, the first file directory is a file directory named "economy", a plurality of first file items directly under the "economy" file directory are shown in the list of fig. 6 (here, a plurality of files such as "temp" folder, "temp 0" folder, "[ finance and economic eyes ] 20150202 dairy farmer …" file are included), and the file view also displays attribute information of each first file item, such as the last modification date, type, size, duration attribute.

S604, the client sends a first operation request for a target file item in the file view to the server through the video network;

optionally, in S604, the client may receive a first operation request for a target file item in the file view in the file management interface; then, the client sends the first operation request to the server through the video network.

The file management interface comprises a file view displayed according to a file display mode of the first operating system;

the file view comprises a first file directory of the server and attribute information of a first file item directly subordinate to the first file directory;

wherein the first operation request comprises attribute information of the target file item, the first file directory and operation information of the target file item, and the target file item is a file item selected from the first file item or a file item requested to be newly created under the first file directory;

for example, the first operation request expresses an operation request for a certain target file item in the file view as shown in fig. 6.

For example, the user double-clicks the "temp" folder, and then triggers the first operation request, which indicates that the contents of the "temp" folder are referred to. Then the first operation request may carry: attribute information of the "temp" folder (e.g., folder name — temp), a directory to which the "temp" folder belongs (i.e., a first file directory, herein, a folder directory named "economy"), and operation information for the "temp" folder (herein, query operation information).

The operation information is also different with different access types, the access type of the first operation request can be newly created, deleted, modified and inquired, and the corresponding operation information is newly created operation information, deleted operation information, modified operation information and inquired operation information.

Therefore, when the access type is deletion, modification or inquiry, the target file item is a file item selected from the first file items displayed by the file view; and when the access type is new, the target file item is a file item requested to be newly created under the first file directory in the file view by the user.

When the access type of the first operation request is new, the attribute information of the target file item is the attribute of the target file item requested to be new (for example, a folder named as "test" is newly created under the economic folder, and the attribute comprises type-folder and name- "test").

When the access type of the first operation request is modification, the modification operation information may include modified content of an object of the target file item (the object may be an attribute of the target file item or a file content of the target file item). For example, if the name of the "temp" folder shown in fig. 6 is modified and the user triggers modification to "temp 1", the modification operation information includes "temp 1".

Optionally, after S604, the method according to the embodiment of the present invention may further include:

s502, the server receives the first operation request, and operates the target file item according to the attribute information and the operation information in the first file directory locally based on the second operating system to generate an operation result;

s503, the server sends the operation result to the client through the video network.

In the Linux operating system on the server side, when a certain file item is accessed, a code instruction needs to be input by a user to trigger the access of the file item, so after the server receives the first operation request, the target file item with the attribute information in the directory can be operated according to the operation information based on the "economic" directory of the Linux operating system on the server side according to the information carried in the first operation request, and an operation result is generated.

S605, the client receives an operation result of the server after the server operates the target file item in a first file directory local to the server based on the first operation request;

s606, the client displays the operation result corresponding to the target file item in the file view according to the operation result.

Alternatively, the user may, in one embodiment,

when the operation information is new operation information, the server may create a target file item with attribute information (i.e., attribute information of the target file item carried by the first operation request) under the first file directory in a manner of inputting a code instruction, and then the operation result is the attribute information of the target file item that has been created;

for example, a folder named "test" is newly created under the "economy" directory in the storage space on the server side, and the operation result is the attribute information of the "test" folder.

When the operation information is deletion operation information, the operation result is null data;

when the operation information is deletion operation information, the server may delete a target file item having the attribute information (i.e., the attribute information of the target file item carried by the first operation request) under the first file directory in a manner of inputting a code instruction, and then the operation result is a deletion result, i.e., null data;

when the operation information is modification operation information, the operation result comprises the modified attribute information of the target file item, wherein when the type of the target file item is a file, the operation result further comprises the modified file content of the target file item;

when the operation information is query operation information, if the type of the target file item is a file, the operation result is the file content of the target file item, and if the type of the target file item is a folder, the operation result is attribute information of a third file item in the server directly subordinate to the target file item.

For example, if the user requests to open a "temp" folder in the file view shown in fig. 6, the corresponding operation result is the attribute information of the file and/or folder actually stored in the "economic" folder- "temp" folder on the server side.

As another example, the user requests to open an MP4 file named "[ finance and economics eyes ] 20150202 dairy farmer …" in the file view shown in fig. 6, the operation result is that the server side actually stores audio and video data (corresponding to the file content of the target file item) of an MP4 file named "[ finance and economics eyes ] 20150202 dairy farmer …" under the "economics" folder.

Wherein, the client side can display the operation result of the target file item requested to be operated in the file view shown in fig. 6.

For example, if the first operation request indicates that a "temp" folder in an "economic" folder is opened, in this step, the attribute information of the third file item stored in the "temp" folder under the "economic" folder, which is received from the server, may be displayed, for example, as shown in fig. 7, the third file item includes a "111" folder and a "222" folder.

In the embodiment of the invention, the client can send the attribute information of the first file directory in the server and the first file item directly subordinate to the first file directory, displayed in a file view mode in a local file management interface of the client, when the client wants to directly access the file data of the server through the video network, the operation can be carried out on each file item in the file view, or a new file item is created to trigger a first operation request for a target file item in the file view, and after receiving the first operation request, the target file items stored in the server side and under the first file directory can be actually operated by the server according to the first operation request, and the operation result is returned to the client through the video network, so that the client can directly display the operation result in the file view. For a user at a client side, the user accesses file data at a server side connected remotely just like accessing a local disk, and can show a file directory at the server side and attribute information of a file item in a file view supported by a local operating system, so that the convenience of the user for accessing data at the server side of the operating system different from the client side is improved.

Taking the server as a linux operating system and the client as a Windows operating system as an example, the client can access file data of the server through the internet of view like accessing its own local disk (e.g., C disk, D disk) under a Windows system.

Optionally, in any embodiment of the present invention, when a client and a server in the video network perform data or signaling interaction through the video network, taking the example that the a-side sends data 1 to the B-side, the a-side encapsulates the data 1 according to a preset storage protocol, encapsulates the data 1 into a data packet a1 capable of accessing a file system of the server, then encapsulates the data packet a1 according to the video network protocol (a video network packet header may be added to a header of the data packet a1 in a specific encapsulation manner), generates a data packet a2, and then sends the data packet a2 to the B-side through the video network.

After receiving the data packet a2, the B-side may decapsulate the data packet a2 according to the video networking protocol (e.g., remove the video networking header) to obtain the loaded data, and generate a data packet a 1; then, the B-side decapsulates the packet a1 according to a preset storage protocol, to obtain data 1 in the packet a 1.

The A end can be a client end of the video network, and the B end is a server of the video network; or the A terminal is a server of the video network, and the B terminal is a client of the video network.

The preset storage protocol is related to an operating system and a file system of the server, and the preset storage protocol is a protocol which can directly access the file system of the server under a second operating system. The predetermined storage protocol may be an internet protocol or a video networking protocol.

In an example, when the operating System of the server is a Linux operating System, the predetermined storage protocol is an iscsi (internet Small Computer System interface) protocol that the file System of the Linux supports access. The ISCSI protocol is an internet-based storage technology.

The data interaction between the A terminal and the B terminal and the process of analyzing the received data are realized through the processes. It should be understood by those skilled in the art that the interaction manner of data such as request/data/signaling between the client and the server according to the embodiment of the present invention is as described in the foregoing embodiment, and therefore, for the interaction process for a certain data, the detailed description of the encapsulation and decapsulation processes of the data packet is omitted, and only the data is generally described by sending/receiving the data through the video network.

Optionally, before S601, the method according to the embodiment of the present invention may further include:

and establishing connection between the client and the server, and executing an interaction process between the client and the server after the client and the server establish connection.

Specifically, for example, the client invokes an interface to initiate a connection request, which includes parameters such as an address of a server requesting the connection, and the connection request may be the above-mentioned preset storage protocol, and then the connection request of the preset storage protocol is encapsulated as an internet protocol packet and sent to the server, and the server approves the connection, while the client and the server are connected.

Optionally, after S602, the method according to the embodiment of the present invention may further include:

s607, the client locally saves the received first file directory and the attribute information of the first file item directly subordinate to the first file directory.

The client locally stores the first file directory on the server side and the attribute information of the first file item directly subordinate to the first file directory, so that the client can conveniently and directly obtain the first file directory and the attribute information of the first file item from the local after starting the client next time, the attribute information of each first file item is displayed on the local file management interface according to the first file directory, the first file directory and the attribute information of the first file item do not need to be obtained from the server again, repeated acquisition of data is avoided, and the generation efficiency of an access interface of the client side to the data of the server is improved.

The execution sequence of S607 and S603 is not limited in the present invention.

Optionally, after S607 and after S502, the method according to the embodiment of the present invention may further include:

s504, the server sends the second file directory of the operated target file item in the server and the attribute information of the operated target file item to the client through the video network;

after the server operates the target file item in the local first file directory and generates the operation result, the server may send the operation result to the client, and may also send the second file directory (equivalent to the latest directory information of the target file item after the operation) of the operated target file item on the server side and the attribute information of the operated target file item (equivalent to the latest attribute information of the target file item after the operation) to the client.

Wherein, because the operation information is different, the directory information of the operated target file item may be changed or not, if the directory information is not changed, the second file directory is consistent with the first file directory; if the directory information is changed, the second file directory is different from the first file directory.

The operation result, the second file directory and the attribute information of the operated target file item may be sent to the client together or may be executed separately, and the execution sequence of S503 and S504 is not limited in the present invention.

S608, the client updates the first file directory stored locally according to the second file directory;

for example, a first file directory saved on the client side is updated.

For example, if the operation information is new operation information, such as a new folder, and a "test" folder is created under the "economic" folder, the second file directory of the target file item (i.e., the "test" folder) after the server operation is the "economic" folder- "test" folder, and therefore, the client needs to update the first file directory ("economic" folder) and add the subdirectory of the "economic" folder (i.e., the "test" folder).

For example, the operation information is deletion operation information, such as a delete folder, the server deletes the "temp" folder under the "economic" folder, and the second file directory of the operated target file item (i.e., the "temp" folder) is empty, so that the client needs to update the first file directory (the "economic" folder), specifically, delete the "test" folder directly subordinate to and under the "economic" folder.

For example, the operation information is modification operation information, for example, a folder is modified, the server modifies the name of a "temp" folder under an "economic" folder to "temp 3", and the second file directory of the operated target file item (i.e., the "temp 3" folder) is the "economic" folder > "temp 3" folder, so that the client needs to update the first file directory (the "economic" folder), specifically, the name of a subfolder "temp" under the "economic" folder directly subordinate to the first file directory is updated to "temp 3".

For example, the operation information is query operation information, for example, a certain folder is queried, the server queries the content in the "temp" folder under the "economic" folder, and specifically queries the "111" folder and the "222" folder, then the second file directories of the operated target file items (i.e., the "111" folder and the "222" folder) are the "economic" folder- "temp" folder- "111" folder, and the economic "folder-" temp "folder-" 222 "folder, respectively, so that the client needs to update the first file directory (" economic "folder), specifically, two subdirectories are added to the subfolder" temp "under the directly subordinate and the" economic "folder, that is, the" 111 "folder and the" 222 "folder.

And S609, the client updates the attribute information of the first file item stored locally according to the operated attribute information of the target file item.

For example, the attribute information of the first file item saved in S607 is updated.

Wherein, both S608 and S609 are executed after S504, and the execution sequence between S608 and S609 is not limited in the present invention.

In addition, S605 is executed after S503, and S606 is executed after S605, and the execution order between S503 and S504 is not limited in the present invention.

Wherein, no matter the type of the target file item is a file or a folder, if the target file item is a file item selected from the first file item, the attribute information of the target file item after the operation is used to update the attribute information of the target file item before the operation, which is locally saved; if the target file item is a file item requested to be newly created in the first file directory, then when updating, the attribute information of the newly added target file item is added to the attribute information of the locally stored first file item.

In the embodiment of the present invention, although the file view on the client side displays the file directory on the server side and the information of the file items under the file directory without actually storing the file, after the client side triggers the first operation request to the file view, the client side may receive, from the server, the second file directory to which the target file item operated by the server belongs in the server and the attribute information of the target file item after the operation, update the first file directory locally stored by using the second file directory for the change of the file directory caused by the first operation request, and update the attribute information of the first file item locally stored by using the attribute information of the target file item after the operation for the change of the attribute information of the file caused by the first operation request, so that the file directory stored on the client side and the attribute information of each file item in the file directory are both the same as the file directory stored on the server side and the attribute information of each file item on the server side The file directory of the file which is actually stored and the attribute information of the file are synchronized, and the local directory and the attribute information of the file are synchronized each time the client accesses the file on the server side, so that the condition of data access error when the client accesses the server file next time is avoided.

Optionally, after S601, the method according to the embodiment of the present invention may further include:

s505, the server responds to the file system information request, and sends the plurality of first subfiles of the first file directory and the attribute information of the second file items indirectly subordinate to the first file directory to the client through a video network;

the execution sequence of S505 and S501 is not limited in the present invention, and both can be executed simultaneously, sent to the client as a set of data, or executed independently. Whether the server performs S501 alone or S505 and S501, respectively, is configurable.

Taking the first file directory as an economic folder as an example, in S501, the server side returns attribute information of the first file item directly stored in the economic folder by the server side; in S505, the server may further send the plurality of subfiles in the "economic" folder and the attribute information of the plurality of second file items indirectly subordinate to the "economic" folder to the client.

Wherein the attribute information of the second file items indirectly belonging to the economic folder is the attribute information of the second file items belonging to the subfiles.

Optionally, after S505, the method according to the embodiment of the present invention may further include:

s610, the client locally saves the received multiple first sub-file directories of the first file directory and the attribute information of the second file item indirectly subordinate to the first file directory.

In the embodiment of the present invention, when the client performs a query operation on a certain first file item (here, the type is a folder) in the file view, the client may query attribute information of a file item under a target file item that a user needs to query from the first file directory stored locally and the plurality of first subfiles thereof, without sending a request to the server side, thereby improving data access efficiency of the client side.

The present invention does not limit the execution order of S505 and S501. However, S610 is executed after S505, and S602 is executed after S501, so the present invention does not limit the execution sequence between S610 and S602.

Optionally, after the client receives the first operation request, the method according to the embodiment of the present invention may further include:

if a target file item in the first operation request is a file item selected from the first file items, the type of the target file item is a folder, and the operation information is query operation information, the client searches whether a target first file subdirectory matched with the target file item exists in the plurality of first file subdirectories according to the first operation request;

for example, as shown in fig. 7, if the "111" folder and the "222" folder which belong to "temp" are already saved locally before the client receives the first operation request, if the first operation request of this time is to open the "temp" folder under the "economic" folder, the client may query whether there are "temp" file subdirectories (including the "111" folder and the "222" folder) which belong to the "economic" folder in the locally saved plurality of file subdirectories under the "economic" folder;

if so, the client displays the target first file subdirectory and the attribute information of a target second file item directly subordinate to the target first file subdirectory in a mode of opening the target file item in the file view;

wherein, as shown in FIG. 7, the "temp" file subdirectory (i.e., "New volume (F:) > economic > temp") and the attribute information (here including name, modification date, type, size) of the target second file item (i.e., "111" folder and "222" folder) directly subordinate to the "temp" file subdirectory can be displayed in such a manner that the "temp" folder is opened.

If not, the client side executes the step of sending the first operation request to the server through the video network to obtain the '111' folder and the '222' folder and the attribute information thereof from the server side.

In the embodiment of the invention, when the client acquires the file system information of the server, the client acquires the first file directory and the plurality of first sub-file directories of the first file directory, and attribute information of a first file item directly subordinate to the first file directory, and attribute information of a second file item indirectly subordinate to the first file directory, and a local save is performed, when the client displays a file view based on the first file directory, when the client receives a first operation request for a target file item in the file view, it may first be queried locally whether there is a target file item (here the type is folder) or a file directory to which it belongs that needs to be queried, if the file directory exists, the file directory under the target file can be displayed without being acquired from the server side, and the response speed of the capacity to the operation request of the client is improved.

Then, when the client receives the first file operation request triggered by the target file item in the displayed file view shown in fig. 7 again, the processing manner of the embodiment of the present invention is similar to the processing manner of the file view shown in fig. 6 in the foregoing embodiment, and the processing manner of the first file operation request triggered by the target file item is similar to that of the file view shown in fig. 6, and details are not repeated here.
