some of the technologies applied in the video networking are as follows:

network Technology (Network Technology)

Network technology innovation in video networking has improved over traditional Ethernet (Ethernet) to face the potentially enormous video traffic on the network. Unlike pure network Packet Switching (Packet Switching) or network Circuit Switching (Circuit Switching), the internet of vision technology employs network Packet Switching to satisfy the demand of Streaming (translated into Streaming, and continuous broadcasting, which is a data transmission technology, converting received data into a stable and continuous stream, and continuously transmitting the stream, so that the sound heard by the user or the image seen by the user is very smooth, and the user can start browsing on the screen before the whole data is transmitted). The video networking technology has the advantages of flexibility, simplicity and low price of packet switching, and simultaneously has the quality and safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.

Switching Technology (Switching Technology)

The video network adopts two advantages of asynchronism and packet switching of the Ethernet, eliminates the defects of the Ethernet on the premise of full compatibility, has end-to-end seamless connection of the whole network, is directly communicated with a user terminal, and directly bears an IP data packet. The user data does not require any format conversion across the entire network. The video network is a higher-level form of the Ethernet, is a real-time exchange platform, can realize the large-scale high-definition video real-time transmission of the whole network which can not be realized by the current Internet, and pushes a plurality of network video applications to high-definition and unification. Server Technology (Server Technology)

The server technology on the video network and the unified video platform is different from the traditional server, the streaming media transmission of the video network and the unified video platform is established on the basis of connection orientation, the data processing capability of the video network and the unified video platform is irrelevant to flow and communication time, and a single network layer can contain signaling and data transmission.

Network Security Technology (Network Security Technology)

Service Innovation Technology (Service Innovation Technology)

The unified video platform integrates services and transmission, and is not only automatically connected once whether a single user, a private network user or a network aggregate.

As shown in fig. 1, the video network is divided into an access network and a metropolitan network.

The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). 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 may be directly connected to the access switch or may be directly connected to the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch or directly connected with the node server.

Therefore, the whole video network is a network structure controlled by a hierarchical centralized way, and the network controlled by the node server and the metropolitan area server can be in various structures such as a tree, a star, a ring and the like.

The access network part can form a unified video platform (circled part), and a plurality of unified video platforms can form a video network; each unified video platform may be interconnected via metropolitan area and wide area video networking.

Visio networking device classification

The packets coming from the network interface module 201, the cpu module 203 and the disk array module 204 all enter the switching engine module 202; the switching engine module 202 performs an operation of looking up the address table 205 on the incoming packet, thereby obtaining the direction information of the packet; and stores the packet in a queue of the corresponding packet buffer 206 based on the packet's steering information; if the queue of the packet buffer 206 is nearly full, it is discarded; the switching engine module 202 polls all packet buffer queues for forwarding if the following conditions are met: 1) The port send buffer is not full; 2) The queue packet counter is greater than zero. The disk array module 204 mainly implements control over the hard disk, including initialization, reading, writing, and other operations on the hard disk; the CPU module 203 is mainly responsible for protocol processing with an access switch and a terminal (not shown in the figure), configuring an address table 205 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 204.

The access switch:

Wherein, the packet (uplink data) coming from the downlink network interface module 301 enters the packet detection module 305; the packet detection module 305 detects whether the Destination Address (DA), the Source Address (SA), the packet type, and the packet length of the packet meet the requirements, if so, allocates a corresponding stream identifier (stream-id) and enters the switching engine module 303, otherwise, discards the stream identifier; the packet (downstream data) coming from the upstream network interface module 302 enters the switching engine module 303; the incoming data packet of the CPU module 304 enters the switching engine module 303; the switching engine module 303 performs an operation of looking up the address table 306 on the incoming packet, thereby obtaining the direction information of the packet; if the packet entering the switching engine module 303 is from the downstream network interface to the upstream network interface, the packet is stored in the queue of the corresponding packet buffer 307 in association with the stream-id; if the queue of the packet buffer 307 is close to full, it is discarded; if the packet entering the switching engine module 303 is not from the downlink network interface to the uplink network interface, the data packet is stored in the queue of the corresponding packet buffer 307 according to the guiding information of the packet; if the queue of the packet buffer 307 is nearly full, it is discarded.

The switching engine module 303 polls all packet buffer queues, which in this embodiment is divided into two cases:

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 byte, 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) is composed 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 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 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 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 application: 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 as follows: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, which is located between the reserved bytes and the payload of the packet.

A Network Interface Controller (NIC), also called a network interface controller, a network adapter, a network card, or a local area network receiver (LAN adapter), is a piece of computer hardware designed to allow a computer to communicate over a computer network. It belongs to layer 1 of the OSI model because it possesses a MAC address. It allows the users to connect to each other by cable or wirelessly. Each network card has a unique 48-bit serial number, called the MAC address, which is written in a ROM on the card. Each computer on the network must have a unique MAC address. No two produced network cards have the same address.

The connection between the computer and the external LAN is realized by inserting a network interface board into the main case (or inserting a PCMCIA card into the notebook computer).

After the target server is set, file transmission parameters corresponding to a file to be sent may be set, and it can be understood that, when the target server is a plurality of application servers, the same file transmission parameters may be set for each target server, or different file transmission parameters may be set for each target server, specifically, the file transmission parameters may be set according to business requirements, which is not limited in this embodiment of the present application.

Of course, the file transmission parameter may also be a parameter customized by the probe management server according to the current network bandwidth, that is, the file transmission parameter is automatically adapted, and specifically, the probe management server may query the current bandwidth condition and the bandwidth condition of the network in the transmission process according to the current bandwidth condition of the network, so as to limit the transmission speed.

After the target server selected by the user and the file transmission parameter are obtained when the file to be sent is obtained, step 502 is executed.
