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) 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, is 64 bytes if the type of the datagram is various protocol packets, and is 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., more than 2 connections between a node switch and a node server, between a node switch and a node switch, and between 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 all passively executed, which is different from label allocation of MPLS, which 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, which is located between the reserved bytes and the payload of the packet.
Based on the characteristics of the video networking, one of the core concepts of the embodiment of the invention is provided, the video networking terminal sends a video data playing request to the video networking node server through the included video data on-demand module and the interaction layer object, and plays the video data returned by the video networking node server according to the protocol of the video networking.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a method for playing video data according to the present invention is shown, where the method may be applied to a video networking terminal in a video networking, where the video networking terminal includes a video data on-demand module and an interaction layer object, the video networking further includes a video networking node server, and the video data on-demand module communicates with the video networking node server through the interaction layer object, and the method specifically includes the following steps:
In the embodiment of the invention, the video data on-demand module can display the video data on-demand list in the video network terminal, and the user selects the video name in the video data on-demand list so as to play the selected video data on the video network terminal. For example, the user performs a click operation on the video name C1 in the video-on-demand list C, that is, the user performs a trigger operation on the video data of the video name C1, where the click operation information is trigger information operation information of the user on the video data of the video name C1.
In the embodiment of the invention, when the video data on demand module is initialized, the video data on demand list can be obtained from the video network node server. In a preferred embodiment of the present invention, the video data on demand module may send a request instruction to the interaction layer object, where the request instruction is used to obtain a video data on demand list, the interaction layer object sends the request instruction to the video networking node server, and the video networking node server returns the video data on demand list to the interaction layer object according to the request instruction; the interaction layer object sends the video data on-demand list to a video data on-demand module; and the video data on-demand module loads and displays the video data on-demand list. For example, after the video data on demand module a is started, the video data on demand module a sends a request instruction D for obtaining a video data on demand list C to an interaction layer object B, the interaction layer object B transmits the request instruction D to a video networking node server E, the video networking node server E returns the preset video data on demand list C to the interaction layer object B, the interaction layer object B sends the received video data on demand list C to the video data on demand module a, and the video data on demand module a loads and displays the video data on demand list C on a video networking terminal.
In the embodiment of the invention, the video data on demand list not only contains the video name, but also contains the detailed information of the video data such as the video number, the video duration and the like. The video number is a unique identifier of the video data, that is, one or a string of video numbers corresponds to one unique video data. And the video name and the video number have a corresponding relation, and after a user performs a triggering operation on a certain video name, the video number corresponding to the video name triggered by the user can be determined according to the corresponding relation between the video name and the video number.
In the above example, the user performs the trigger operation on the video name C1 in the video-on-demand list C, the video-on-demand module receives the trigger operation information F, and since the video name C1 and the video number C001 have a corresponding relationship, the video number corresponding to the trigger operation information F is C001. In the video networking terminal, the video data on demand module A transmits the video number c001 to the interaction layer object B.
In the embodiment of the invention, when the interactive layer object sends the playing request of the video data to the video network node server, the video number can be directly sent to the video network node server, and the playing request information containing the video number can also be sent to the video network node server. No matter the interaction layer object sends the video number or sends the play request information, the video networking node server still needs to obtain the video number finally.
