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 data 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 various data packets are available, and is 32+1024 or 1056 bytes if a single multicast data packet is available, but 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.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a subscription method of a protocol conversion device according to the present invention, which may be applied to a resource pool proxy server, may include the following steps:
step 501: a notification message of the protocol conversion device is received.
The protocol conversion device is any protocol conversion device subscribed by the resource pool proxy server, and the notification message is used for representing that the resource state information of the protocol conversion device changes.
In the embodiment of the present invention, the resource pool proxy server is a Virtual or physical device in the video Network, which can be used as a proxy of the protocol conversion device, and is similar to a Virtual Private Network (VPN) in the video Network, so that a management mechanism for managing a change situation of resource state information of the protocol conversion device needs to be set for the resource pool proxy server.
In a specific application, a subscription relationship exists between the resource pool proxy server and the protocol conversion server subscribed by the resource pool proxy server, that is, when the subscribed protocol conversion device changes the resource state information, a notification message is automatically sent to the subscribed resource pool proxy server to notify that the resource state information changes on the protocol conversion device, so that the resource pool proxy server updates the resource state information for the change of the resource state information.
Step 502: and acquiring the resource change data of the protocol conversion equipment according to the notification message.
Illustratively, based on the subscription relationship between the resource pool proxy server and the protocol conversion device, after receiving the notification message, the resource pool proxy server divides a part of the area into its memory for recording the change of the resource status information corresponding to the notification message, i.e. storing the resource change data, so as to update the resource status information of the protocol conversion device to the latest information. In a specific application, in order to reduce the repetition rate of processing operations and improve the processing efficiency, when the resource change frequency of the external device connected to the protocol conversion device is high and the change amount is large, the change information of the resource state information within a certain time period may be acquired after the notification message is received, and the following steps may be performed together.
Step 503: and sending the resource change data to a subscriber who subscribes the resource pool proxy server.
In a specific application, after the corresponding resource change data is obtained through the above steps, the resource pool proxy server may send the resource change data to the corresponding subscriber in a message queue manner. That is to say, the resource pool proxy server can be used as a subscriber and also can be used as a subscribed party, wherein when the resource pool proxy server is used as a subscriber, the corresponding subscribed party is a protocol conversion device; when it is used as a subscribed party, the corresponding subscribed party is a user end connected to the original protocol conversion device, for example, one or more mservers. That is, the using end (one or more mservers, etc.) of the originally utilized protocol conversion device is taken as the subscriber of the resource pool proxy server related to the present invention, and the resource pool proxy server acquires the change of the resource state information sent by the corresponding protocol conversion device, that is, the resource change data, so as to realize the unified management of the resource state information by the resource pool proxy server and perform effective resource allocation.
It should be noted that, the number of the protocol conversion devices subscribed by the resource pool proxy server is usually multiple, and then dynamic virtual terminal numbers can be allocated among the using terminals corresponding to the multiple protocol conversion devices, that is, the virtual terminal numbers are adaptively allocated according to the communication requirements of the actual using terminals, so as to overcome the problem that resources cannot be efficiently allocated when the protocol conversion devices are used for allocating the virtual terminal numbers. For example, n virtual terminal numbers are pre-allocated to each protocol conversion device, it may happen that a user terminal on a certain protocol conversion device is busy, the n virtual terminal numbers are not enough to meet a use requirement, while a user terminal on another protocol conversion device is idle, that is, the n virtual terminal numbers are not used, and by utilizing a resource pool proxy server to subscribe one or more protocol conversion devices, reasonable utilization and dynamic allocation of idle resources are realized, so as to improve the efficiency of the video networking system.
In summary, the embodiment of the present invention may be applied to a resource pool proxy server, and receive a notification message of a protocol conversion device; acquiring resource change data of the protocol conversion equipment according to the notification message; sending the resource change data to a subscriber of the resource pool proxy server; the protocol conversion device is any protocol conversion device subscribed by the resource pool proxy server, and the notification message is used for indicating that the resource state information of the protocol conversion device changes. Therefore, the resource pool proxy server can be used for recording the change of the resource state information of the subscribed protocol conversion equipment within the preset time length and then uniformly sending the change to the subscriber, so that the resource state change can be efficiently managed, and the use efficiency of the video network resources can be improved.
Referring to fig. 6, which shows a flowchart of specific steps of an embodiment of a subscription method of a protocol conversion device according to the present invention, before step 501, the method may further include the following steps:
step 504: and subscribing the protocol conversion equipment to acquire the notification message sent by the protocol conversion equipment under the condition that the resource state information of the protocol conversion equipment is changed.
In a specific application, the resource pool proxy server adds the protocol conversion device to be managed on the resource pool proxy server in a subscription manner, so that a corresponding notification message can be generated to inform the resource pool proxy server under the condition that the resource state information of the subscribed protocol conversion device is changed.
Referring to fig. 7, which is a flowchart illustrating specific steps of an embodiment of a subscription method for a protocol conversion device according to the present invention, the acquiring resource change data of the protocol conversion device according to a notification message in step 502 may include the following steps:
step 5021: and recording the resource change data according to the notification message so as to temporarily store the resource change data in a memory allocated by the resource pool proxy server for the conference conversion equipment.
The resource change data includes data indicating a change in the resource state information of the protocol conversion device within a preset time period from the reception of the notification message.
For example, the resource pool proxy server may receive the resource change data sent by the protocol conversion device within a preset time length after receiving the notification message sent by the protocol conversion device, where the preset time length is, for example, 20 seconds; that is to say, as long as the resource change data sent by the protocol conversion device is received within 20 seconds, the resource pool proxy server temporarily stores the resource change data in the memory allocated to the protocol conversion device until the preset time length is finished, and then performs the operation of step 5022, and within the preset time length, the resource pool proxy server is in a waiting-to-receive state to perform batch processing on the resource change data, so as to improve the processing efficiency.
Step 5022: and under the condition that the preset time length is exceeded, carrying out serialization processing on the resource change data temporarily stored in the memory.
In a specific application, when the preset time duration is exceeded, it may be understood that the resource state of the protocol conversion device is updated or changed, that is, the resource state information of the protocol conversion device remains stable, and the resource pool proxy server no longer receives the resource change data sent by the corresponding protocol conversion device. That is, after the 20 seconds, if a new change of the resource status information occurs, that is, a new notification message is received, the operation of this step is executed again to obtain the change data of the resource status information in the next preset duration.
It should be noted that the preset duration may be adjusted according to a specific application scenario to adapt to device characteristics or network characteristics in an actual application scenario, and the present invention is not limited specifically. In addition, by the technical scheme provided by the invention, the information of the resource state change within the preset time length is recorded and is sent to the subscriber side, so that the efficient resource management can be carried out.
In a specific application, the resource change data acquired within a preset time duration is stored in a file system (storage space) of the resource pool proxy server after being serialized, so that the resource change data can be sent to a subscriber of the resource pool proxy server.
Optionally, referring to fig. 8, a flowchart illustrating specific steps of an embodiment of a subscription method of a protocol conversion device of the present invention is shown, after step 503, the method may further include the following steps:
step 505: and deleting the resource change data from the resource pool proxy server.
For example, since the protocol conversion device may have a large amount of change, that is, the amount of the generated resource change data is large, and then after the resource change data is sent to the corresponding subscriber through step 503, the resource change data stored on the resource pool proxy server (in the storage space) may be correspondingly deleted, so as to optimize the storage performance of the resource pool proxy server and avoid unnecessary consumption and waste of the storage space.
Optionally, referring to fig. 9, which is a flowchart illustrating specific steps of an embodiment of a subscription method of a protocol conversion device according to the present invention, the sending of the resource change data to the subscriber of the resource pool proxy server in step 503 may include the following steps:
In a specific application, the resource change data is sent to the subscriber(s) of the resource pool proxy server by using a message queue, for example, the resource change data generated within 20 seconds after the notification message is received may be added to an event queue to be sent as an event to be sent, so as to wait for sending.
