The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.
The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

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 a task processing method of a video network according to an embodiment of the present invention is shown, which may specifically include the following steps:
step 501, a network management data collection center receives a video networking task sent by a network management server aiming at a certain video networking server.
In the video network, a plurality of local video networks are divided, that is, various video network terminals, video network servers, peripheral devices and the like are connected with each other to form a computer communication network within a local geographic range (such as Shanghai region, Xinjiang region and the like).
In the embodiment of the invention, a network management server and a plurality of video network servers are deployed in the video network.
The network management server may be a server for managing video networking devices in a video networking whole network, and is generally deployed in headquarters (e.g., beijing).
The video network server is a local video network server, which refers to a server configured for a certain local video network, manages data and equipment of the local video network, and performs service processing of video network management, and service areas among the video network servers are not coincident.
As shown in fig. 6, the network management server is configured with an associated network management data collection center, and each of the network management servers is configured with an associated network management data collector.
By changing the data acquisition layer of the network management into a distributed structure consisting of a network management data acquisition center and network management data acquisition devices, each network management data acquisition device can perform parallel control and management on the video networking server one by one, so that the performance pressure of the data acquisition layer of the network management on the server is distributed to each network management data acquisition device.
It should be noted that the network management server and the network management data acquisition center may be deployed in the same device, or may be deployed in independent devices, which is not limited in this embodiment of the present invention.
The user logs in the network management client, provides a visual operation interface for the user, generates a task request aiming at a certain video network server according to the operation of the user and a Transmission Control Protocol (TCP) Protocol, and sends a service request to the network management server.

In the embodiment of the invention, the registration information (such as collector ID) of the network management data collector is stored in a database in the network management server.
After receiving the login request, the network management data acquisition center extracts the collector ID, and inquires whether the collector ID is the registered collector ID from the network management server.
If the data collector ID is not the registered collector ID, the collector ID is confirmed to be illegal, and the connection with the data collector is disconnected.
If the collector ID is the registered collector ID, the collector ID is confirmed to be legal, and whether the same collector ID is in a login state or not is further judged.
If the same collector ID is in the login state, an error is returned, and the connection with the data collector is disconnected.
And if no same collector ID is in the login state, determining that the login is verified, and allowing login.
And 803, if the login verification is passed, the network management data acquisition center stores the connection with the network management data acquisition unit and records the ID of the acquisition unit as the login state.
If the network management data collector passes the login verification, the connection with the network management data collector is kept, and the collector ID is recorded as the login state.
Step 804, the network management data collection center stores the server identifier associated with the collector ID.
