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 application: 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.
Example one
Referring to fig. 5, a flowchart of a first step of an embodiment of a method for accessing a Web server according to an embodiment of the present application is shown, where the method is applied to a video network, the video network is communicatively connected to an ethernet network, where the video network includes a first video network proxy server, a video network core server, a second video network proxy server, and a Web server, and the ethernet network includes a user terminal, where the method may specifically include the following steps:
in the embodiment of the application, the Http protocol is adopted between the user terminal and the first video network proxy server for data transmission, and the video network protocol is adopted between the proxy server and the core server in the deployment video network for data transmission. For a user terminal needing to enter the video network, a virtual terminal number and a virtual mac address are required to be provided for identifying the user terminal.
In a specific implementation, the first video network proxy server is deployed in the video network and can communicate with the user terminals located in the same local area network. The user terminal initiates request information to a first video network proxy server to request to access a Web server deployed in the video network, so that data of the Web server are acquired.
For example, if a user wants to access a tangula video monitoring resource management scheduling command system (tangula platform) deployed in the video network, the user may send an Http request message to the first video network proxy server through the user terminal, and the first video network proxy server converts data based on the internet protocol into data based on the video network protocol.
It should be noted that the user terminal may be a mobile terminal, such as a mobile phone, a tablet computer, a personal digital assistant, a wearable device (such as glasses, a watch, etc.), and the like, and is generally a mobile terminal capable of playing audio and video. The operating system of the internet terminal may include Android (Android), IOS, Windows Phone, Windows, and the like, which is not specifically limited in this embodiment of the present application.
in the embodiment of the application, a core server of the video network in the video network can serve as a router and a switch to forward received video network data, and meanwhile, a message forwarding service program is preset in both a proxy server and the core server in the video network, and request information of a user terminal can be forwarded through the message forwarding service program.
In a preferred embodiment of the present application, step 502 may include the following sub-steps;
substep S11, the first video network proxy server adopts the request information to generate a port number adapted to the request information;
in this embodiment of the application, the first video networking proxy server may generate a port number adapted to request information according to the request information initiated by the user terminal, and return the port number to the user terminal, so that the user terminal may receive a result corresponding to the request information through the socket.
In the specific implementation, the user terminal can access a first video network proxy server located in the same local area network through the browser, the first video network proxy server monitors a port through the message forwarding service, waits for TCP connection, and returns a new socket to the user terminal to represent the connection request when the connection request is monitored, so that the user terminal can receive a result returned by the Web server through the socket.
In an example of this embodiment, the user terminal (192.168.0.112) accesses a first internet-of-view proxy server (192.18.0.114:80) located in the same lan through a browser, the message forwarding service of the first internet-of-view proxy server monitors a port and waits for a connection to come, when receiving a connection request 1 (192.168.0.112:6045), a new socket6045 is returned to represent the connection request, where the connection request 1 corresponds to the socket6045 and represents a result returned by the Web server when data received on the socket6045 are all requests for the Web server of request 1, and the first internet-of-view proxy server can distinguish a forwarded Http request according to the new socket, and when receiving a result returned by the Web server, the user terminal 192.168.0.112 is returned through which socket (socket 6045 in this embodiment): 6045.
for example, a first internet-of-things proxy server may generate an adapted socket for a request message initiated by a user terminal to access the tangula platform, then encapsulate the request message and the socket, convert data based on an internet protocol into data based on an internet-of-things protocol, generate first protocol data, and then send the first protocol data to an internet-of-things core server.
Substep S12, the first video network proxy server packages the request information and the port number to generate first protocol data;
in a particular implementation, the first protocol data is data based on an internet of view protocol. The first video network proxy server can encapsulate request information and corresponding socket initiated by the user terminal, and convert data based on the internet protocol into data based on the video network protocol.
In sub-step S13, the first internet of view proxy server sends the first protocol data to the internet of view core server.
In a specific implementation, the first internet of vision proxy server converts the data based on the internet protocol into first protocol data based on the internet of vision protocol, and may send the first protocol data to the core server of the internet of vision, and the core server of the internet of vision is forwarded to the server deploying the Web service.
in this embodiment of the application, after the first video network proxy server sends the request information to the video network core server, the video network core server may forward the request information to the corresponding second video network proxy server through the message forwarding program.
In a specific implementation, the second Internet of things proxy Server is deployed with a Web service, and the Web service runs in an Internet Information Server (IIS). After the first video network proxy server sends the first protocol data to the video network core server, the video network core server sends the first protocol data to the second video network proxy server.
It should be noted that, in the video networking network, at least one second video networking proxy server is deployed, and different second video networking proxy servers may deploy different Web services or deploy the same Web service.
in this embodiment of the application, after receiving the request information forwarded by the video network core server, the second video network proxy server may send the request information to the Web server.
In a specific implementation, after the core server of the video networking sends the first protocol data to the second video networking proxy server, the second video networking proxy server can analyze the first protocol data to obtain a socket and request information, then a TCP connection adapted to the socket is established, and then the second video networking proxy server sends the request information to the Web server through the TCP connection.
For example, when the second VIP proxy receives the VIP message, it starts parsing the VIP message, and parses out the socket6045 and the Http request packet in the message, then establishes a new TCP connection (192.168.0.115:6046), which is bound to socket6045, and then sends the Http request packet to the Web server in the proxy (192.168.0.115: 80).
in a specific implementation, the request response information is information for accessing the Web server initiated by the user terminal. And after receiving the request information, the Web server processes the request information to generate corresponding request response information.
in a specific implementation, after the Web server processes the Http request, the processed result may be returned to the second internet-of-things proxy server through TCP connection.
For example, after receiving the first protocol data, the second internet-of-video proxy server parses out the Http request message, then forwards the Http request message to the tangula platform, and after the IIS server of the tangula platform processes the request, returns the response result of the request to the second internet-of-video proxy server.
in this embodiment of the application, after receiving the request response information sent by the Web server, the second video networking proxy server may send the request response information to the core video networking server.
In a preferred embodiment of the present application, step 507 may include the following sub-steps;
substep S21, the second video network proxy server packages the request response information and the port number to generate second protocol data;
in a particular implementation, the second protocol data is data based on an internet of view protocol. The second video network proxy server can encapsulate the request response information returned by the Web server and the corresponding socket, and convert the data based on the Internet protocol into the data based on the video network protocol.
In sub-step S22, the second internet of view proxy server sends the second protocol data to the internet of view core server.
In a specific implementation, the second internet-of-things proxy server converts the data based on the internet protocol into second protocol data based on the internet protocol, and the second protocol data can be sent to the internet-of-things core server and forwarded to the first internet-of-things proxy server by the internet-of-things core server.
For example, after receiving the data returned by the Web server, the second internet proxy server encapsulates the Http response message part in the data packet with the socket6045 into the internet protocol and sends the encapsulated Http response message part to the internet core server (192.168.0.114), and then actively closes the TCP connection.
in step 509, the first internet of things proxy server sends the request response information to the user terminal, and the user terminal is configured to access the Web server according to the request response information.
In the embodiment of the application, after the video network core server sends the request response information to the first video network proxy server, the first video network proxy server sends the request response information to the user terminal.
In a specific implementation, after receiving the second protocol data, the first internet of things proxy server may parse the second protocol data to obtain request response information, and then send the request response information to the user terminal, so that the user terminal may access the Web server according to the request response information to obtain corresponding data.
In an example of the embodiment of the present application, after receiving the second protocol data, the first internet of things proxy server (192.168.0.114) parses the Http response message and the socket6045 from the second protocol data, then sends the Http response message to the user terminal (192.168.0.112) through the socket6045 over the TCP connection, and actively closes the TCP connection, and after receiving the TCP message, the browser in the user terminal parses the Http protocol content to obtain corresponding data.
For example, the second video network proxy server converts data based on the internet protocol into data based on the video network protocol to generate second protocol data, the second video network proxy server sends the second protocol data to the first video network proxy server through the video network core server, the first video network proxy server analyzes Http message content returned by the tangula platform from the received second protocol data, and then the first video network proxy server returns the Http message content to the user terminal through the previously established TCP connection, so that the user can access the tangula platform deployed in the video network environment through the server in the local area network.
In the embodiment of the application, the first video network proxy server receives request information initiated by a user terminal, then the request information is sent to the second video network proxy server through the video network core server, the second video network proxy server sends the request information to the corresponding Web server, then the Web server processes the request information and returns request response information to the user terminal, so that the user can access the Web server deployed in the video network environment through the user terminal of the local area network, and the server deployed in the video network is used as a data forwarding server, so that the user can access the Web server outside the local area network through the user terminal in the local area network, the research and development efficiency and maintenance efficiency are greatly improved, and the cost is reduced.
