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 |
the Destination Address (DA) consists of 8 bytes (byte), the first byte represents the type of the data packet (e.g. various protocol packets, multicast data packets, unicast data packets, etc.), there are at most 256 possibilities, the second byte to the sixth byte are the addresses of the metro network, and the seventh byte and the eighth byte are the addresses of the access network.
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 types of different datagrams, and is 64 bytes if the type of the datagram is various protocol packets, and 32+1024=1056 bytes if the type of the datagram is a unicast packet, although not limited to the above 2 types.
The CRC consists of 4 bytes and its calculation method follows 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 a Label of Multi-Protocol Label switching (MPLS), and assuming that there are two connections between a device a and a device B, there are 2 labels for a packet from the device a to the device B, and 2 labels for a 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 0x0001. 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 characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the log information configuration file is modified and stored in the running process of the application program according to the protocol of the video network, and the application program can output the log information according to the modified log information configuration file without restarting.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for outputting log information according to the present invention is shown, and the method can be applied to a video network device in a video network, wherein the video network device includes one or more of the following: the method comprises the following steps:
In the embodiment of the invention, in the running process of the application program in the video network equipment, a user can modify and store the log information configuration file of the application program at any time.
For example, during the operation of the application b in the video network terminal a, the software engineer may modify the log information configuration file c of the application b, and after the modification, save the log information configuration file c to the default position d where the application b saves the log information configuration file c in the video network terminal a.
In the embodiment of the invention, the application program in the video networking device can comprise one or more functional modules, and each functional module can output respective log information. In the log information configuration file, specific log information configuration data for each function module may be configured for each function module of one application program.
Step 503, acquiring a log information configuration file at a default position of the configuration file according to a preset time interval, and analyzing the acquired log information configuration file to obtain log information output condition data.
In the embodiment of the present invention, the log information configuration file is acquired from the default location of the configuration file according to the preset time interval, which aims to acquire the modified log information configuration file in time, so that the preset time interval may be set to a shorter time interval, for example, 1 second.
In the embodiment of the present invention, the log information output condition data includes: log information output format data and log information output target data.

In the embodiment of the invention, the log information can contain a large amount of detailed information, wherein the information related to the log information configuration file and needing to be output can be used as effective information.
For example, the log information c of the function module m contains information x1, x2, x3, x4, x5, and x6 generated by the function module m during operation. The log information output format data includes log information output time data, log information output function module name data, and log information output function data. If the log information output time data corresponding information x1, the log information output function module name data corresponding information x3, and the log information output function data corresponding information x6 are valid information corresponding to the function module m, the information x1, the information x3, and the information x6 are valid information corresponding to the function module m.
