2. Video networking packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
| DA | SA | Reserved | Payload | CRC |
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
| DA | SA | Reserved | label (R) | Payload | CRC |
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a directory verification method according to the present invention is shown, which may specifically include the following steps:
the sharing of directories and resources is often required among a plurality of national standard domains, and when one national standard domain initiates a signaling of a sharing request to another national standard domain, the requested national standard domain needs to respond according to the national standard. For example, in the internet of Vision (VIP) Xinjiang project, the internet of Vision (VIP) platform is used as a basic docking platform for docking monitoring resources to platforms such as astronavigation technology, aerospace Changfeng, England, Haokangwei and the like, and the platform is used as an independent national standard domain and is often required to be shared with other national standard domains.
In the embodiment of the invention, when the video networking platform sends the target file to other national standard domains, the target file can be captured through the preset plug-in, the target file can be an intermediate file where a directory and resources shared among the national standard domains are located, and the preset plug-in can be a Wireshark plug-in for analyzing signaling under a video networking protocol.
in a specific implementation, after the target file is obtained, the embodiment of the present invention may cut the target file, and cut the complete target file into a plurality of file blocks, where each file block corresponds to one data packet, so that a plurality of data packets may be obtained through cutting.
in a specific implementation, the plurality of data packets may be parsed to obtain useful fields, where the useful fields may include a Parent ID as the first identifier, a Device ID as the second identifier, a Name of the child resource, and the like.
In an embodiment of the present invention, step 503 may include the following sub-steps:
analyzing the plurality of data packets to obtain an Sip protocol packet; and analyzing the Sip protocol packet to obtain a useful field.
In a specific implementation, after a plurality of data packets are obtained, each data packet may be analyzed to obtain an Sip protocol packet, and then useful fields are obtained through analysis from the Sip protocol packet.
In this embodiment of the present invention, the analyzing the plurality of data packets to obtain the Sip protocol packet may include:
and analyzing the plurality of data packets, judging whether the data packets obtained by analysis are Sip protocol packets, if so, retaining the Sip protocol packets, and if not, discarding the data packets obtained by analysis.
Sip (session Initiation protocol) is a signaling control protocol of an application layer. For creating, modifying and releasing sessions of one or more participants. These sessions may be Internet multimedia conferences, IP telephony or multimedia distribution. The participants of the session may communicate by Multicast (Multicast), mesh Unicast (Unicast), or a mixture of both.
In a specific implementation, after receiving a plurality of data packets, the plurality of data packets may be analyzed to obtain analyzed data packets. At this time, it is necessary to determine whether the obtained analyzed packet is an Sip packet, if so, the Sip packet is retained, and if not, the analyzed packet is discarded.
In the embodiment of the present invention, when it is determined that the parsed data packet is an Sip protocol packet, it is further required to determine whether the Sip protocol packet is a fragment packet, and if so, the fragment packet is retained, and the fragment packet is assembled into a complete Sip protocol packet.
In a specific implementation, when the Sip protocol packet obtained through analysis is a fragment packet, the data in the fragment packet is incomplete, and the fragment packet cannot be directly used at this time, so that the obtained fragment packet can be saved, and after the fragment packets are collected, all the fragment packets are assembled into a complete Sip protocol packet.
in a specific implementation, after the useful field is obtained, the directory tree can be constructed according to the useful field.
In the embodiment of the present invention, the directory may include a child directory and a parent directory, and the useful field may include a first identifier and a second identifier, the first identifier being used for identifying the parent directory, and the second identifier being used for identifying the child directory. Step 504 may thus include the following steps:
and constructing a complete directory tree according to the corresponding relation between the second identifier of the child directory and the first identifier of the parent directory.
In a specific implementation, a complete directory tree may be constructed according to a corresponding equal relationship between the first identifier and the second identifier. Each child resource has both a child directory and a parent directory. Each level directory is a parent directory of the next level directory. For example, the area of the Uygur autonomous region in Xinjiang province is the City state of the Banyin GuoMeng, the area of the Yan Meng city is Yan, the subdirectory of the area of the Uygur autonomous region in Xinjiang province is the father directory of the area of the Yao GuoMeng city, and the subdirectory of the area of the Yan Guoqi city is the father directory of the area of the Yan Guoqi city. At this time, the second identifier corresponding to the sub-directory of the new-jiang Uygur autonomous region is the same as the first identifier corresponding to the parent directory of the Yakulen autonomous State, and the second identifier corresponding to the sub-directory of the Yakulen autonomous State is the same as the first identifier corresponding to the parent directory of the Yanqi county. For another example, Yan Qi county has three schools including the first school, the second school and the third school, and since the three schools all belong to one administrative level, the three schools belong to three different sub-directories under the same parent directory, and thus the three schools have the same parent directory. Based on the correspondence between the child directory and the parent directory, a complete directory tree can be constructed.
In another example of the present invention, the Sip protocol package may be parsed based on a target file captured by Wireshark, an organization directory and resources are extracted, and the constructed organization directory tree is displayed based on a Qt framework, which includes the following detailed steps: 1. inputting a target file captured by Wireshark, wherein the format is Pgapng; reading the file in the Pcap suffix format according to bytes, wherein the head of the data block format is 0x060000 for identifying a valid database, the next four bytes are valid data lengths, extracting the valid data, and converting the valid data into an Xml format of a plaintext according to the Utf-8 format, wherein the Xml is the data in the required Sip protocol packet. Analyzing the data in Xml to obtain the structure of organization directory or resource, putting the structure into the classified collection, taking out all organization directories in the collection, and constructing a complete directory tree according to the relationship that the Parent ID of the child directory is equal to the Device ID of the Parent directory
In a specific implementation, after a complete directory tree is constructed according to the target data, the integrity of the directory data can be checked according to the directory tree.
In the embodiment of the invention, the directory tree can be matched with the directory data of the video networking platform, and the integrity of the directory data can be checked.
In the specific implementation, the directory tree can be matched with the directory data sent by the video networking platform, if the matching is complete, the fact that the directory data sent by the video networking is complete is proved, and the responsibility is not on the video networking platform side. The embodiment of the invention can effectively check whether the directory response format and the content are correct or not, and effectively determine the responsibility attribution party.
