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 invention: 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.
Based on the above-mentioned characteristics of the video network, one of the core concepts of the embodiments of the present invention is presented. As shown in fig. 5, a first embodiment of the present invention provides a video transcoding capacity adjusting method, which is applied in a video network.
To better understand the present embodiment, the video transcoding capacity will first be described. The video transcoding capacity of a system represents the size of the video transcoding requirement which can be met by the video transcoding capacity of the system, and represents the height of the video transcoding capacity of the system, the larger the video transcoding capacity is, the larger the video transcoding requirement which can be met simultaneously is, the smaller the video transcoding capacity is, and the smaller the video transcoding requirement which can be met simultaneously is. The size of the video transcoding capacity is determined by the number of the video transcoding devices which are particularly responsible for the video transcoding task, and the information of the video transcoding devices which are responsible for the video transcoding task is stored in the video transcoding device information queue 12. The more the video transcoding device information stored in the video transcoding device information queue 12 is, the more the number of the video transcoding devices responsible for the video transcoding task is, the larger the video transcoding capacity is, the more the video transcoding device information stored in the video transcoding device information queue 12 is, the smaller the number of the video transcoding devices responsible for the video transcoding task is, and the smaller the video transcoding capacity is. Since the video transcoding service is provided by selecting a corresponding video transcoding device for video transcoding according to each piece of video transcoding device information stored in the video transcoding device information queue 12, if the information of a certain video transcoding device is not stored in the video transcoding device information queue 12, the video transcoding device cannot be selected to process a video transcoding task. Meanwhile, when a certain video transcoding device is removed but the information of the certain video transcoding device is still stored in the video transcoding device information queue 12, it is still possible to select the video transcoding device to process the video transcoding task in the process of providing the video transcoding service, but the video transcoding device is removed, so that an error occurs and the video transcoding work cannot be performed. Therefore, to increase or decrease the system video transcoding capacity, it is necessary to increase or decrease the video transcoding devices and the corresponding video transcoding device information in the video transcoding device information queue 12, so that the increase or decrease of the system video transcoding capacity can be realized.
Based on the foregoing idea of adjusting video transcoding capacity, as shown in fig. 5, a method for adjusting video transcoding capacity according to a first embodiment of the present invention includes the following steps:
step A: and receiving a registration message sent by the unregistered video transcoding device 2 in real time, wherein the registration message contains the information of the unregistered video transcoding device 2.
And B: and storing the information of the unregistered video transcoding device 2 into a video transcoding device information queue 12 to complete the registration of the unregistered video transcoding device 2. The video transcoding device information queue 12 stores therein information of each registered video transcoding device 2. When the video transcoding capacity needs to be increased and the video transcoding device 2 is added, the video transcoding device 2 to be added is an unregistered video transcoding device 2, information of the unregistered video transcoding device 2 needs to be stored in the video transcoding device information queue 12 to complete registration of the video transcoding device 2, after the registration, the video transcoding device 2 may be selected to process a video transcoding task when the video transcoding task exists, namely, after the registration, the video transcoding capacity is substantially increased. The increased video transcoding capacity is brought about by the video transcoding device 2.
And C: receiving heartbeat information sent by each registered video transcoding device 2 according to a first preset frequency in real time, and updating information of the registered video transcoding devices 2 sending the heartbeat information in the video transcoding device information queue 12 when the heartbeat information is received. The registered video transcoding device 2 sends heartbeat information at regular time to indicate the online state of the video transcoding device 2, and when the heartbeat information of a certain video transcoding device 2 is received, the video transcoding device 2 is indicated to be online, namely the video transcoding device 2 is not removed, and a video transcoding task can be optionally processed.
Step D: and detecting whether each registered video transcoding device 2 is online or not according to a second preset frequency, and removing the information of the registered video transcoding devices 2 which are not online from the video transcoding device information queue 12. Specifically, the method for detecting whether the registered video transcoding device 2 is online includes:
and when the heartbeat information of the registered video transcoding equipment 2 to be detected is not received within the preset time length, judging that the registered video transcoding equipment 2 to be detected is not on line, otherwise, judging that the registered video transcoding equipment 2 to be detected is on line. When a registered video transcoding device 2 is not online, indicating that the video transcoding device 2 has been removed, it is necessary to remove its information from the video transcoding device information queue 12, so as to avoid errors caused by selecting the actually removed video transcoding device 2 to process the video transcoding task.
The first preset frequency, the second preset frequency and the preset duration can be set and adjusted according to actual conditions.
The video transcoding capacity adjusting method provided by the invention further comprises the following steps:
step E: and returning registration result information to the unregistered video transcoding device 2 and returning update result information to the registered video transcoding device 2 which sends heartbeat information. And informing the unregistered video transcoding device 2 of the registration result by returning registration result information, and informing the registered video transcoding device 2 of the information updating result by returning updating result information.
The information of the registered video transcoding device 2 includes identification information of the registered video transcoding device 2, and the information of the unregistered video transcoding device 2 includes identification information of the unregistered video transcoding device 2. The identification information serves as identification information of the video transcoding apparatus 2 for identifying the video transcoding apparatus 2.
The adjusting method is executed by the video transcoding server 1, and the registered video transcoding devices 2 are distributed and communicated with the video transcoding server 1 through the video network.
Based on the video transcoding capacity adjusting method, a second embodiment of the present invention provides a video transcoding server 1, where the video transcoding server 1 is applied in a video network and can be used to execute the method. As shown in fig. 6, the video transcoding server 1 includes:
the registration module 13 is configured to receive, in real time, a registration message sent by the unregistered video transcoding device 2, where the registration message includes information of the unregistered video transcoding device 2, and store the information of the unregistered video transcoding device 2 in the video transcoding device information queue 12, so as to complete registration of the unregistered video transcoding device 2; the information of each registered video transcoding device 2 is stored in the video transcoding device information queue 12;
