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.

in a specific implementation, the video networking sip server and the second forwarding server located in the same host can establish a UDP connection when the host is started. After receiving the first protocol data sent by the core server of the video network, the second forwarding server can convert the first protocol data based on the video network protocol into a registration message based on the internet protocol, and then the second forwarding server sends the registration message to a corresponding UDP port of the sip server of the video network through the UDP port of the second forwarding server, so that the sip server of the video network obtains the registration message.
in this embodiment of the application, after receiving the session request message sent by the core server of the video network, the second host may generate a session response message for the session request message, and send the session response message to the core server of the video network.
In a specific implementation, after obtaining a registration message sent by an internet of view sip client, an internet of view sip server deployed in a second host performs sip registration, generates a session response message for the session request message, and then sends the session response message to a second forwarding server through UDP connection, where the second forwarding server converts the session response message based on the internet protocol into second protocol data based on the internet of view protocol, and sends the second protocol data to an internet of view core server.
In step 504, the first host receives a session response message sent by the core server of the video network to establish a session channel with the second host.
In the embodiment of the application, the second host can send the session response message to the first host through the video networking core server, so that a session channel between the first host and the second host is established, and further sip protocol data transmission between the video networking sip client and the video networking sip server is realized.
In a specific implementation, after receiving the second protocol data sent by the core server of the video network, the first forwarding server may convert the second protocol data based on the video network protocol into a session response message based on the internet, and send the session response message to the sip client of the video network through UDP connection, so as to establish a session channel between the sip client of the video network and the sip server of the video network, and enable the user terminal to exchange the sip protocol data through the session channel located in the video network.
In an example of the embodiment of the present application, the client of the video network is connected to the first forwarding server through UDP, and after the first forwarding server receives the sip register message sent by the client of the video network, the sip register message may be encapsulated into an internet of view protocol, generating first protocol data, and sent through an internet of view core server to a second forwarding server, the second forwarding server connected to an internet of view monitoring resource server through a UDP connection, the second forwarding server may parse the received first protocol data and send the sip register message to the internet-of-things monitoring resource server, so that the internet-of-things monitoring resource server returns a response message according to the sip register message, therefore, a session channel between the video network client and the video network monitoring resource server is established, so that the video network client and the video network monitoring resource server can complete the exchange of sip protocol data through the video network.
In the embodiment of the application, the session request message sent by the user terminal through the first host is received through the video network core server, the second host receives the session request message sent by the video network core server, the second host generates the session response message aiming at the session request message and sends the session response message to the video network core server, and the first host receives the session response message sent by the video network core server so as to establish a session channel with the second host, so that the sip client and the sip server can directly communicate through the video network, the convenience of data communication between different hosts is improved, and the usability and the expandability of products are improved.
