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.
Based on the above characteristics of the video network, the link detection method applied to the video network is provided in the embodiment of the invention.
Example one
Referring to fig. 5, a flowchart illustrating steps of a link detection method according to a first embodiment of the present invention is shown, where the method may be applied in a video network, and specifically includes the following steps:
step 501: the conference management system sends a conference initiating instruction.
The test equipment can log in a specific website in the browser to start the conference management system, and the conference can be controlled through the conference management system. The conference initiating instruction comprises identification information of each video network terminal participating in the conference.
Step 502: and each video networking terminal responds to the conference initiating instruction to start the conference.
The conference initiating instruction sequentially passes through the video networking master control server and the video networking server in the video networking system to reach the video networking terminals participating in the conference. And after receiving the conference initiating instruction, each video network terminal responds to the instruction to join the conference. It should be noted that, if one or more video network terminals do not respond to the conference initiating instruction, the conference management system may default to not participate in the conference.
Step 503: the conference management system sets a conference speaking party.
After the conference is started, the conference management system can select one video networking terminal from the video networking terminals in the conference as a conference speaking party, and correspondingly, the selected video networking terminal user carries out conference speaking.
Step 504: and in the speaking process of the conference speaking party, the video network master control server detects the link state between each video network terminal and the conference speaking party.
The link is formed by all nodes on the data through video network, and each link comprises a plurality of nodes. The video network master control server can determine whether the nodes are abnormal by detecting whether data streams sent by a speaking party exist in each node in the link, and the state of each node in the link can reflect the link state of the whole link.
Step 505: and the video networking master control server respectively sends the link state corresponding to each link to the conference management system.
The link state of each link can be determined through step 504, the link state of each link can be displayed in a preset interface after being reported to the conference management system, and a tester can determine the link with the abnormality through the link state of each link displayed in the conference management system, and can more accurately determine which node in the link has the abnormality. After the abnormal node is determined, the method can take measures pertinently to avoid the node from continuing to be in an abnormal state. The abnormal nodes can be recovered to be normal by processing the abnormal nodes, and the video network terminals can successfully receive the conference content output by the conference speaker in the conference.
It should be noted that the link detection method provided in the embodiment of the present invention is not only suitable for detecting a link in a video networking conference, but also suitable for detecting a link involved in a video telephone or a live broadcast watching process.
According to the link detection method provided by the embodiment of the invention, after the conference is started, in the process of speaking by the conference speaking party, the video networking master control server detects the link states between each video networking terminal and the conference speaking party, and respectively sends the link states corresponding to each link to the conference management system, and the conference management system can timely acquire the video networking terminals which cannot successfully receive the conference content and the link states corresponding to the video networking terminals through the link states corresponding to each link, so that the abnormal links are recovered to be normal by adopting corresponding solving measures, the video networking terminals are prevented from always receiving the conference content, and the conference participating experience of users of the video networking terminals can be improved.
Example two
Referring to fig. 6, a flowchart illustrating steps of a link detection method according to a second embodiment of the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:
step 601: the conference management system sends a conference initiating instruction.
The conference initiating instruction comprises identification information of each video network terminal participating in the conference.
Step 602: and the video network master control server receives the conference initiating instruction and forwards the conference initiating instruction to the video network server.
In the video networking system, the video networking server performs information interaction with each video networking terminal, so that a conference initiating instruction needs to be sent to the video networking server and then forwarded to each video networking terminal.
Step 603: and the video networking server respectively sends the conference initiating instruction to the video networking terminals corresponding to the identification information of each video networking terminal.
After the video network terminal corresponding to the identification information of each video network terminal successfully receives the conference initiating instruction, if other services are not processed currently, the video network terminal can respond to the received conference initiating instruction and join the conference. Correspondingly, if the video networking terminal receives the conference initiating instruction, the information for indicating the current busy state can be returned to the conference management system when other services are processed currently, and the conference management system can determine that the video networking terminal cannot participate in the conference due to the busy state through the information.
Step 604: and each video networking terminal responds to the conference initiating instruction to start the conference.
One way in which the preferred video networking terminal opens the conference in response to the conference initiation instruction is as follows:
firstly, each video network terminal respectively returns a conference response message;
secondly, the video network server receives a conference response message returned by each video network terminal;
the conference response message is a message fed back after the video networking terminal joins the conference. If the video networking terminal cannot participate in the conference due to the fact that the business is busy, information for indicating that the current business is busy is returned to the conference management system.
And finally, the video network server sends the conference response message returned by each video network terminal to the conference management system through the video network master control server.
Step 605: the conference management system sets a conference speaking party.
The tester can select any video network terminal participating in the conference as a conference speaking party in the conference management system interface, and correspondingly, the selected video network terminal user makes conference speaking.
Step 606: and in the speaking process of the conference speaking party, the video network master control server detects the link state between each video network terminal and the conference speaking party.
One way to preferably detect the link status between the terminal of the video network and the conference speaker is as follows:
aiming at a link between each video network terminal and a conference speaking party, a video network master control server respectively detects data streams of each node contained in the link; determining whether each node receives data sent by a conference speaking party; and generating the link state of the link according to the determination result corresponding to each node.
In the actual detection process, if the node receives data sent by a conference speaking party, the node is determined to be normal, otherwise, the node is determined to have abnormality. After the status of each node in a link is determined, the link status of the link may be generated, and the link status may reflect the status of each node in the link.
Step 607: and the video networking master control server respectively sends the link state corresponding to each link to the conference management system.
The video network master control server sends the link state of each link to the conference management system, and testers can acquire the link state of each link through the conference management system.
