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:

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:

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.

The application provides a method for cooperatively processing files, which is applied to a whiteboard server in a video network. Fig. 5 is a flowchart illustrating a method for collaboratively processing a file according to an embodiment of the present application. Referring to fig. 5, the method for co-processing files of the present application may include the steps of:

step S11: receiving a first file sent by a first video network terminal, and loading the first file into a whiteboard room, wherein the whiteboard room is created for the first video network terminal by the whiteboard server in advance.

In this embodiment, a plurality of video network terminals are connected to the whiteboard server. Electronic whiteboard is all installed to each video network terminal, and electronic whiteboard means electronic whiteboard software, or other application software that have electronic whiteboard function, and through this type of software, the user can edit all kinds of files on the video network terminal, and wherein the file can be: OFFICE files, PDF files, picture files, etc.

In general, a user may independently edit a first file by using an electronic whiteboard, and when the user needs to share the first file to other users and collaboratively process the first file with the other users, the user needs to apply for creating a whiteboard room from a whiteboard server, where the whiteboard room is used to manage a process in which the whiteboard server collaboratively processes the first file by using a plurality of video networking terminals.

The first video network terminal actively shares the file so as to be watched by other video network terminals or edit the file, and the file shared by the first video network terminal is the first file. After the whiteboard room is successfully created, the whiteboard server loads the first file into the whiteboard room for users of other video network terminals to view or edit, and all users in the whiteboard room can view or edit the activated files in the whiteboard room but cannot view or edit the files which are not loaded into the whiteboard room.

Step S12: and periodically acquiring first ink information generated by each video network terminal in the whiteboard room aiming at the first file, wherein the video network terminals comprise a first video network terminal and a second video network terminal, and the second video network terminal is different from the first video network terminal.

When the first video network terminal loads the first file into the whiteboard room, all the second video network terminals can not only view the first file, but also edit the first file.

The first ink information refers to information generated when the first file is edited, for example, when the first file is a WORD file, the first ink information may be comments made to the WORD file, parameters generated when the style of the document is adjusted, parameters generated when the format of the text is adjusted, and the like. Each video network terminal can edit the first file through an electronic whiteboard installed on the video network terminal, and generates first ink information. The whiteboard server acquires first ink information generated by all video network terminals in the whiteboard room in a T period. Illustratively, the time when the whiteboard server last acquires the first ink information is T0, the time when the whiteboard server currently acquires the first ink information is T1, and the difference between T0 and T1 is T, all the first ink information acquired by the whiteboard server at the time T1 is the sum of the first ink information generated by each video network terminal in the time period of T0-T1.

In a period of time, one video network terminal can generate a plurality of pieces of first ink information, and the video network terminals are not influenced mutually when generating the first ink information.

Step S13: and sorting the first ink mark information.

Specifically, step S13 may include:

and summarizing the first ink information according to the time stamp carried by the first ink information sent by each video network terminal.

The time when each video network terminal generates the first ink information can be different, and the first ink information is sorted according to the sequence of the time stamps of each piece of the first ink information, so that errors can be prevented when each video network terminal updates the first file on the electronic whiteboard.

The time stamp of the first ink information is marked by the electronic whiteboard. For example: the first video network terminal inserts a picture into the first file, the electronic whiteboard firstly generates a piece of first ink information, and the adopted format can be as follows: xxxyyyyzzz, where XXX is an event corresponding to the action of inserting a picture, YYY is information of the event, such as the size, position, and parameters of the picture, ZZZ is a timestamp, and the electronic whiteboard uses the current time of the first network-of-view terminal as the timestamp.

After acquiring first ink information generated by each video network terminal in a whiteboard room in a certain period, the whiteboard server sorts and arranges all the first ink information according to the sequence of the time corresponding to the timestamp of each piece of first ink information.

Step S14: and sending the sorted first ink mark information to each video network terminal in the whiteboard room, so that the video network terminals edit the first file on the basis of the sorted first ink mark information.

Specifically, step S14 may include:

The whiteboard server synchronizes the first ink mark information after arrangement to each video network terminal in the whiteboard room in a thread synchronization mode, each video network terminal updates the first file on the electronic whiteboard of the whiteboard by using the first ink mark information after arrangement to obtain the updated new first file, so that each video network terminal in the whiteboard room can continuously edit the new first file, and the cooperative processing of the first file is realized through the plurality of video network terminals.

The following describes a process of cooperatively processing a first file by a plurality of video network terminals, taking a first video network terminal in a whiteboard room as a and a second video network terminal as B, C, D as an example. During the period of time T0-T1 (the difference between T0 and T1 is a period), a inserts a picture X into the first file at time T1 to generate first ink information MES1, B adds an annotation Y to the first file at time T2 to generate first ink information MES2, C thickens the text of paragraph Z in the first file at time T3 to generate first ink information MES3, D does not edit the first file and does not generate first ink information, wherein T1, T2 and T3 are located between T0-T1. At time T1, the whiteboard server obtains A, B, C, D all first ink information generated during the period T0-T1, including: MES1, MES2 and MES3, MES1, MES2 and MES3 are sorted according to the chronological order of t1, t2 and t3 and then synchronized to A, B, C, D. A. B, C, D, respectively using the sorted MES1, MES2 and MES3 to update the original first file on the electronic whiteboard, specifically, reading the MES1, MES2 and MES3 in sequence according to the time sequence of t1, t2 and t3, editing the original first file, and obtaining a new first file, for example: t1, t2 and t3 are sorted according to time sequence to be t2, t1 and t3, when updating, MES2 is read first, an annotation Y is added in the original first file, MES1 is read, a picture X is inserted in the original first file, MES3 is read finally, and characters of a paragraph Z in the original first file are thickened. The new first file contains both the annotation Y added to the a inserted picture X, B and the text of paragraph Z bold with C. In other words, A, B, C, D sees the same new first file on its own electronic whiteboard after the update is complete. By analogy, the whiteboard server periodically acquires A, B, C, D first ink information generated by each whiteboard server, and updates the first ink information to A, B, C, D after arrangement, so that cooperative processing of A, B, C, D four video network terminals on the first file is realized.

Fig. 6 is a flowchart illustrating a method for joining a second video network terminal according to an embodiment of the present application. Referring to fig. 6, optionally, after the first file is loaded into the whiteboard room, the method for collaboratively processing the file of the present application further includes the following steps:

step S21: and receiving a request for entering the whiteboard room initiated by the second video network terminal.

Step S22: verifying whether the second video network terminal has the permission to enter the whiteboard room according to the request;

step S23: and if the second video network terminal has the permission of entering the whiteboard room, adding the second video network terminal into the whiteboard room, and sending the latest first file to the second video network terminal, wherein the latest first file is obtained by updating the sorted first ink information.

And the second video network terminal in the whiteboard room has the authority to operate the first file. If the second video network terminal needs to acquire the permission for operating the first file, a request for entering the whiteboard room needs to be actively sent to the whiteboard server, and after the whiteboard server verifies that the second video network terminal initiating the request has the permission for entering the whiteboard room, the latest first file is sent to the second video network terminal, so that the second video network terminal can collaborate with other video network terminals in the whiteboard room to edit the latest first file.

The method and the system provide a channel for the second video network terminal to enter the whiteboard server actively, convenience is increased for the plurality of video network terminals to collaboratively edit the first file, and meanwhile, a permission verification link is set for the second video network terminal to enter a whiteboard room, so that safety in a file processing process is guaranteed.

Fig. 7 is a flowchart illustrating another method for joining a second video network terminal according to an embodiment of the present application. Referring to fig. 7, optionally, after the first file is loaded into the whiteboard room, the method for collaboratively processing the file according to the present application may further include the following steps:

step S31: receiving an invitation list sent by the first video network terminal;

step S32: extracting a second video network terminal in the invitation list, and verifying whether the second video network terminal has the permission to enter the whiteboard room;

step S33: and if the second video network terminal has the permission of entering the whiteboard room, adding the second video network terminal into the whiteboard room, and sending the latest first file to the second video network terminal, wherein the latest first file is obtained by updating the sorted first ink information.
