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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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.

Example one

Referring to fig. 5, a flowchart illustrating steps of a method for processing concatenated data according to a first embodiment of the present invention is shown.

The cascade data processing method of the embodiment of the invention can comprise the following steps:

step 501, a subordinate site management platform obtains the number of times that a single subordinate site management platform is allowed to call a push interface in a preset unit time by the superior site management platform.

The embodiment of the invention can be applied to the communication processes of video conferences, video telephones and the like. In order to manage the communication users more conveniently, a mode of upper and lower management can be adopted, each level is provided with a corresponding site management platform, and the cascade data processing method provided by the embodiment of the invention can be applied to the site management platform. The site management platform comprises an upper site management platform and lower site management platforms, wherein one upper site management platform is connected with a plurality of lower site management platforms, and one lower site management platform is connected with a plurality of user terminals. For example, for a city-scale video conference, a city may be used as an upper level, the city corresponds to one upper level site management platform, each district in the city is used as a lower level, each district corresponds to one lower level site management platform, and each lower level site management platform is connected to each user terminal in the district. The user terminal may be a conference terminal participating in a video conference, such as a mobile phone.

The upper-level site management platform can provide a push interface, and each lower-level site management platform can send related information to the upper-level site management platform by calling the push interface. In the embodiment of the invention, the load of the superior site management platform can be reduced by limiting the times of allowing a single subordinate site management platform to call the push interface in the preset unit time. Therefore, the subordinate site management platform can acquire the number of times that the superior site management platform allows a single subordinate site management platform to call the push interface within a preset unit time, and then calculate the push time interval for pushing information to the superior site management platform according to the number of times. The preset unit time can be set to any applicable value such as 1s and 1 min.

Step 502, the subordinate station management platform calculates the pushing time interval according to the times.

According to the number of times that the upper-level site management platform allows a single lower-level site management platform to call the pushing interface in the preset unit time, the lower-level site management platform can calculate the pushing time interval. The specific calculation process will be described in detail in the following embodiment two.

Step 503, the subordinate site management platform detects the state of the connected user terminal, and caches the state information of the user terminal with the changed state in a preset memory.

The subordinate site management platform detects the state of the connected user terminal, the state of the user terminal can comprise on-line state, off-line state, busy state and the like, the state change condition is reported to the superior site management platform, and the superior site management platform carries out overall planning, analysis and the like according to the state change condition. However, in the embodiment of the present invention, in order to solve the problem that the load of the upper level platform is greatly increased and even the system is crashed when the reported data volume is large, after the lower level site management platform detects that the state of the user terminal changes, the state information of the user terminal with the changed state is not directly reported to the upper level site management platform, but a memory may be preset, and the state information of the user terminal with the changed state is temporarily cached in the preset memory.

Step 504, when the lower-level site management platform reaches the pushing time interval, the lower-level site management platform calls the pushing interface to send the state information of the user terminal with the changed state to the upper-level site management platform.

The subordinate site management platform can provide a timing function, and when the pushing time interval is reached, the pushing interface is called to send the state information of the user terminal with the changed state to the superior site management platform, so that the number of concurrent messages of pushing information of the pushing interface calling the superior site management platform is reduced, and the load of the superior site management platform is further reduced.

In the embodiment of the invention, the lower-level site management platform does not directly push the state information of the changed user terminal to the upper-level site management platform, but caches the state information firstly and uniformly pushes the state information when the pushing time interval is reached, so that the load of the upper-level site management platform is reduced, and the stability of the upper-level site management platform is improved; and the pushing time interval is calculated according to the times that the upper site management platform allows a single lower site management platform to call the pushing interface in the preset unit time, and the self performance of the upper site management platform is considered, so that the calculated pushing time interval is more reasonable.

Example two

Referring to fig. 6, a flowchart illustrating steps of a method for processing concatenated data according to a second embodiment of the present invention is shown.

step 601, the subordinate site management platform obtains the number of times that the superior site management platform allows a single subordinate site management platform to call a push interface in a preset unit time.

One upper site management platform can be connected with a plurality of lower site management platforms, and each lower site management platform connected with the upper site management platform can respectively execute the cascade data processing method provided by the embodiment of the invention. This embodiment takes a processing procedure of a subordinate site management platform as an example.

In the embodiment of the present invention, the number of times that a single subordinate site management platform calls a push interface is allowed by a superior site management platform in a preset unit time may be calculated according to a preset number of concurrencies allowed by the superior site management platform in the unit time and the number of subordinate site management platforms currently connected to the superior site management platform. The preset concurrency number may be set to any applicable value according to the performance of the upper-level site management platform, for example, when the performance of the upper-level site management platform is higher, the preset concurrency number may be set to a larger value, and when the performance of the upper-level site management platform is lower, the preset concurrency number may be set to a smaller value, for example, the preset concurrency number may be set to 100 or 200. The user data of different subordinate management platforms may be differentiated by a numerical rule (e.g., a code field is added to the user table to represent a coding rule), such as 1 st subordinate management platform, 2 nd subordinate management platform, … …, nth subordinate management platform, etc.

The calculation process of the number of times that the upper-level site management platform allows a single lower-level site management platform to call the push interface in a preset unit time can be calculated by the upper-level site management platform according to the concurrency number and the number, and can also be calculated by the lower-level site management platform according to the concurrency number and the number.

Thus, in the first preferred embodiment, this step 601 may include: and the subordinate site management platform acquires the times of allowing a single subordinate site management platform to call a push interface in a preset unit time, which are sent by the superior site management platform.

The superior site management platform can acquire the preset concurrency number allowed by the superior site management platform in unit time and the number of subordinate site management platforms currently connected with the superior site management platform, and the number of times that a single subordinate site management platform is allowed to call a push interface in the preset unit time by the superior site management platform is calculated according to the concurrency number and the number. After calculation, the superior site management platform sends the number of times to each connected subordinate site management platform, and each subordinate site management platform can acquire the number of times sent by the superior site management platform.

The process that the superior site management platform calculates, according to the concurrency number and the number, the number of times that the superior site management platform allows a single subordinate site management platform to call a push interface in a preset unit time may include: and the superior site management platform calculates a first quotient obtained by dividing the concurrency number by the number, and uses the first quotient as the number of times that the superior site management platform allows a single subordinate site management platform to call a push interface in a preset unit time.

It should be noted that the embodiment of the present invention may be applied to video networking and may also be applied to internet. If the method is applied to the video networking, the superior site management platform can send the times to the subordinate site management platform in the form of data packets based on the video networking protocol through the video networking protocol. If the method is applied to the internet, the superior site management platform may send the times to the subordinate site management platform through the internet protocol in the form of data packets based on the internet protocol.

In a second preferred embodiment, this step 601 may include: acquiring preset concurrency numbers, which are transmitted by the superior site management platform and allowed by the superior site management platform in the unit time, and the number of subordinate site management platforms currently connected by the superior site management platform by the subordinate site management platform; and the subordinate site management platform calculates the times of allowing a single subordinate site management platform to call a push interface in a preset unit time according to the concurrency number and the number.

The upper site management platform can acquire the preset concurrency number allowed by the upper site management platform in unit time and the number of the lower site management platforms currently connected with the upper site management platform, and sends the concurrency number and the number to each lower site management platform. Each subordinate site management platform can acquire the concurrency number and the quantity sent by the superior site management platform, and the times of allowing a single subordinate site management platform to call the push interface in a preset unit time by the superior site management platform are calculated according to the concurrency number and the quantity.

The process that the subordinate site management platform calculates, according to the concurrency number and the number, the number of times that the superior site management platform allows a single subordinate site management platform to call a push interface in a preset unit time may include: and the subordinate site management platform calculates a first quotient value obtained by dividing the concurrency number by the number, and uses the first quotient value as the number of times that the superior site management platform allows a single subordinate site management platform to call a push interface in a preset unit time.

It should be noted that the embodiment of the present invention may be applied to video networking and may also be applied to internet. If the method is applied to the video networking, the superior site management platform can send the concurrency number and the quantity to the subordinate site management platform in the form of data packets based on the video networking protocol through the video networking protocol. If the method is applied to the internet, the superior site management platform can send the concurrency number and the quantity to the subordinate site management platform through the internet protocol in the form of data packets based on the internet protocol.

Step 602, the subordinate station management platform calculates the pushing time interval according to the times.

According to the number of times that the upper-level site management platform allows a single lower-level site management platform to call the pushing interface in the preset unit time, the lower-level site management platform can calculate the pushing time interval for pushing information to the upper-level site management platform.

In a preferred embodiment, the process of calculating the push time interval according to the number of times may include: and the subordinate station management platform calculates a second quotient value of the unit time and the times, and takes the second quotient value as the pushing time interval.

Step 603, the subordinate site management platform detects the state of the connected user terminal, and caches the state information of the user terminal with the changed state in a preset memory.

Each subordinate site management platform can be connected with a plurality of user terminals, and each subordinate site management platform manages the user terminals connected with each subordinate site management platform. The subordinate site management platform may detect a state of the connected user terminal. The subordinate site management platform may detect the state of the connected user terminal in real time, or may detect the state of the connected user terminal according to a preset period (for example, the preset period may be 1s, 2s, or the like), which is not limited in this embodiment of the present invention.

The subordinate site management platform may preset a memory for storing the state information, and when detecting that the state of the user terminal changes, the subordinate site management platform may cache the state information of the user terminal whose state changes in the preset memory.

Preferably, the buffer may be saved in a terminal identifier-current state form, for example, if the states of terminal a, terminal B, and terminal C change, the state of terminal a changes to online, the state of terminal B changes to offline, the state of terminal C changes to busy, the buffer may be cached as terminal a-online, terminal B-offline, terminal C-busy, and so on. Of course, the present invention may also be stored in other manners, and those skilled in the art may adopt any suitable manners, which is not limited by the embodiments of the present invention.

And 604, when the lower-level site management platform reaches the pushing time interval, calling the pushing interface to send the state information of the user terminal with the changed state to the upper-level site management platform.

The subordinate site management platform may provide a timing function, for example, a timer may be set, and when it is determined that the push time interval is reached, the push interface is called to send the state information of the user terminal whose state is changed, which is cached in the memory, to the superior site management platform.

It should be noted that the embodiment of the present invention may be applied to video networking and may also be applied to internet. If the state information is applied to the video network, the subordinate site management platform can send the state information to the superior site management platform in the form of a data packet based on a video network protocol through the video network protocol. If the state information is applied to the internet, the lower website management platform may send the state information to the upper website management platform through the internet protocol in the form of a data packet based on the internet protocol.

Step 605, the subordinate site management platform clears the state information of the user terminal with the changed state, which is cached in the preset memory.

In a preferred embodiment, after the lower site management platform sends the state information cached in the memory to the upper site management platform, the state information of the user terminal whose state is changed and cached in the memory can be cleared, so that the memory is released, and resources are saved.

The following examples are given. For example, the unit time is set to be 1s, the number of concurrences allowed by the upper node management platform in the unit time (i.e., 1s) is 100, the number of lower node management platforms currently connected to the upper node management platform is 10, the number of times that the upper node management platform allows a single lower node management platform to call the push interface in the unit time (i.e., 1s) is calculated to be 100/10-10, and the push time interval between the lower node management platform and the upper node management platform is calculated to be 1 s/10-100 ms/time. The lower-level site management platform is internally provided with a memory and a time switch, when state information needs to be pushed, the state information is stored in the memory, a timer is arranged, the state information in the memory is integrally pushed to the upper-level site management platform after 100ms, then the memory is emptied, and timing is carried out again.

Step 606, the subordinate site management platform determines whether the subordinate site management platform connected to the superior site management platform changes. If yes, returning to the step 601; if not, return to step 603.

In a preferred embodiment, the change may be a change in number, considering that the subordinate site management platform to which the superior site management platform is connected may be changed. For example, when a new subordinate station management platform is accessed, the number of connected subordinate station management platforms is increased; or a connected subordinate site management platform is disconnected, the number of connected subordinate site management platforms is reduced. The change may affect the number of times that the upper level site management platform allows a single lower level site management platform to call the push interface within a preset unit time. Therefore, in the embodiment of the present invention, the subordinate site management platform may further determine whether the subordinate site management platform connected to the superior site management platform changes, and execute corresponding operations according to whether the subordinate site management platform changes, so as to adjust the pushing time interval according to the change condition, so that the pushing time interval is more suitable for the current load condition of the superior site management platform.

If the status information changes, the process returns to step 601, the number of times that the upper site management platform allows a single lower site management platform to call the push interface in a preset unit time is obtained again, the push time interval is calculated again according to the number of times, the status of the connected user terminal continues to be detected, the status information of the user terminal with the changed status is cached in a preset memory, and the push interface is called to send the status information of the user terminal with the changed status to the upper site management platform according to the recalculated push time interval when the push time interval is reached. If the state of the connected user terminal is not changed, returning to step 603, continuing to detect the state of the connected user terminal, caching the state information of the user terminal with the changed state into a preset memory, and calling a push interface to send the state information of the user terminal with the changed state to a superior site management platform according to the current push time interval when the push time interval is reached.

Corresponding to the above step 601, if the above first preferred embodiment is adopted in step 601, when the subordinate site management platform connected to the superior site management platform changes, the preset concurrency number allowed by the superior site management platform in unit time and the number of the subordinate site management platforms currently (i.e. after the change) connected to the superior site management platform may be obtained, and the number of times that a single subordinate site management platform is allowed to call a push interface in the preset unit time by the superior site management platform is obtained by calculation according to the concurrency number and the number, and is sent to the subordinate site management platform. Therefore, if the subordinate site management platform receives the number of times that the superior site management platform sent by the superior site management platform allows a single subordinate site management platform to call the push interface within the preset unit time, it may be determined that the subordinate site management platform connected to the superior site management platform changes, or it may be determined that the subordinate site management platform connected to the superior site management platform does not change. If the subordinate site management platform determines that the subordinate site management platform connected to the superior site management platform changes, the process may return to step 601, and specifically may return to the first embodiment adopted in step 601. If the subordinate site management platform determines that the subordinate site management platform connected to the superior site management platform has not changed, the process may return to step 603.

If the second preferred embodiment is adopted in step 601, when the subordinate site management platform connected to the superior site management platform changes, the superior site management platform may obtain the preset concurrency number allowed by the superior site management platform in unit time and the number of the subordinate site management platforms currently (i.e., after the change) connected to the superior site management platform, and send the concurrency number and the number to the subordinate site management platform. Therefore, if the subordinate site management platform receives the concurrency number and the number sent by the superior site management platform, it can be determined that the subordinate site management platform connected with the superior site management platform changes, otherwise, it can be determined that the subordinate site management platform connected with the superior site management platform does not change. If the subordinate site management platform determines that the subordinate site management platform connected to the superior site management platform changes, the process may return to step 601, and specifically, the second embodiment adopted in step 601 may return to step 601. If the subordinate site management platform determines that the subordinate site management platform connected to the superior site management platform has not changed, the process may return to step 603.

The embodiment of the invention adopts a mode of accumulating and changing the memory, dynamically adjusts the time interval of information pushing according to the platform performance and the number of the cascaded subordinate station management platforms, and achieves stable data reporting. The system stability is improved, and cascade of large magnitude can be supported.
