detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

1 is a schematic flowchart of a step of a scheduling method of a transmitting node according to the first embodiment of the present invention, which may specifically include the following steps:

In step 101, it is determined that there is a new transmission cluster.

In this embodiment, the transport cluster refers to a computer network system that is connected to each other through the Internet, and uses the server closest to each user to send music, pictures, videos, applications, and other files to the faster and more reliable. Users, to deliver high-performance, scalable and low-cost web content to users. For example, the Content Delivery Network (CDN).

The transport cluster can be used for the transmission of stream data, wherein the stream data is data that can be transmitted on the network by means of streaming, and the stream data can be transmitted from one node to at least one transport node. A plurality of stream data transmissions can exist simultaneously on one transmission node, and the transmission cluster is composed of multiple transmission nodes. The transit node is a server that can be used to receive, store, and distribute streaming data.

Large-scale streaming data transmission systems often rely on transport clusters to transmit convective data. The transport clusters are created by adding a new layer of network structure to the existing network, so that users can transmit data to or near the nearest node. The required data. In the transport cluster, a transport node is deployed to buffer the stream data and provide services to the user. For example, video live applications or remote camera applications often rely on transport clusters to transmit streaming data.

At least one transport cluster provides a streaming data transmission service for the client. When the new transport cluster provides the streaming data transmission service for the client, the client determines that there is a new transport cluster. The specific manner may be any applicable manner. This is not limited. For example, the client may obtain a first cluster list that records all the transport clusters from the cluster management server, and determine that there is a new transport cluster by comparing the first cluster list with the locally stored second cluster list; or the client may receive A new transport cluster notification sent by the cluster management server determines that there is a new transport cluster. In the present invention, the cluster management server is a server for managing a transport cluster.

Step 102: Download a corresponding communication configuration code from a communication configuration code base.

In this embodiment, the communication configuration code is code that can be embedded and configured to configure communication between the client and the transport cluster, and the execution communication configuration code can be used to encapsulate the scheduling request and parse the scheduling result. When different transmission clusters perform transmission node scheduling, the methods of encapsulating scheduling requests and parsing scheduling results are different, and corresponding communication configuration codes are required. For example, the communication configuration code can be script code written in the Lua programming language, and the application uses the Lua language as an embedded scripting language to achieve configurability and scalability.

The communication configuration code library is a database in which the communication configuration code corresponding to each transmission cluster is stored, and the communication configuration code library can be used on any applicable server, which is not limited in this embodiment. For example, it can be on a cluster management server.

After the client determines that there is a new transport cluster, it finds the communication configuration code corresponding to the newly added transport cluster from the communication configuration code base, and downloads the communication configuration code corresponding to the newly added transport cluster to the local.

Step 103: When the newly added transport cluster is invoked, the preset interpreter is used to interpret and execute the communication configuration code, and the communication configuration code performs encapsulation of the scheduling request of the transport node according to the communication protocol of the newly added transport cluster. .

In this embodiment, the client invokes the newly added transport cluster to refer to the client transmitting the data through the newly added transport cluster. Specifically, the client may actively select the newly added transport cluster, or the client may receive the cluster scheduling according to the client. The end request selects a new transport cluster for the client.

The interpreter (English: Interpreter), also translated as an interpreter, is a computer program that can translate high-level programming languages directly and line by line. The interpreter does not translate the entire program at once, just like a "middleman", each time you run the program, you must first switch to another language and run it. It runs immediately after translating a line of program descriptions, then translates the next line, and then runs, so it keeps going.

There are different interpreters for different programming languages. In the present embodiment, the preset interpreter is an interpreter that can interpret and execute the communication configuration code. For example, the communication configuration code is written based on the Lua programming language, and the preset interpreter is a general interpreter for the Lua language.

The communication protocol of the newly added transport cluster refers to the rules and conventions that the client must follow to complete communication or service with the transport cluster. For example, the encapsulation rule that the client sends a scheduling request to the transport cluster, the network address of the scheduling server that the client sends the scheduling request to the transport cluster, and the parsing rules after the client receives the scheduling result.

The scheduling request is encapsulated by using a preset interpreter to interpret and execute the communication configuration code, wherein the scheduling request is a scheduling request of the transmitting node sent by the client to the transport cluster. For example, the Lua language universal interpreter is used to interpret and execute the communication configuration code corresponding to the transmission cluster, and the communication configuration code is executed to implement encapsulation of the IP scheduling request data packet to be sent by the client. Specifically, the content included in the data transmission request packet of different transmission clusters is different. Some transmission clusters agree that the IP scheduling request data packet is the identifier of the stream data and the specific string after directly transmitting the domain name address of the cluster, and some The transport cluster contract IP scheduling request packet is a domain name address of the transport cluster in a custom format, an identifier of the stream data, and a specific string.

Step 104: Send the encapsulated scheduling request to the newly added transport cluster.

In this embodiment, the encapsulated scheduling request is sent to the newly added transport cluster, and specifically, when the network address recorded by the communication configuration code corresponding to the transport cluster is accessed, the encapsulated scheduling request is sent. For example, the network address may be a domain name push stream address of the transport cluster in the live broadcast application, and the domain name push stream address may be parsed to send the encapsulated scheduling request to the server for selecting the transport node in the transport cluster.

Step 105: Perform transmission of stream data according to the transmission node scheduled by the newly added transmission cluster.

In this embodiment, the newly added transmission cluster is a client scheduling transmission node, which may be scheduled according to at least one type of information such as a network address of the client and a geographical location, and the selected transmission node is connected to the client network. For a good transmission node, the transmission node may be scheduled for the client according to any applicable scheduling logic, which is not limited in this embodiment. The client establishes a connection with the scheduled transmission node to perform the transmission of the stream data, and specifically includes the client uploading or downloading the stream data.

In summary, according to the embodiment of the present invention, by determining that there is a newly added transmission cluster, the corresponding communication configuration code is downloaded from the communication configuration code base, so that when the newly added transmission cluster provides the streaming data transmission service, the corresponding communication is directly downloaded. Configure the code to add scheduling capabilities for the new transport cluster to the client without applying an application update. Then, when the new transmission cluster is invoked, the communication configuration code is interpreted and executed by using a preset interpreter, and the communication configuration code performs encapsulation of the scheduling request of the transmission node according to the communication protocol of the newly added transmission cluster. Sending the encapsulated scheduling request to the newly added transport cluster, and transmitting the stream data according to the transport node scheduled by the newly added transport cluster. The execution of the communication configuration code can complete the encapsulation of the scheduling request corresponding to the newly added transmission cluster, and then is used to schedule the node to schedule the transmission node, thereby implementing the hot update of the scheduling function of the newly added transmission cluster, thereby avoiding the inconvenience and failure of updating the application. .

In an embodiment of the present invention, preferably, the determining that there is a newly added transport cluster is: obtaining, by the cluster management server, a first cluster list that records all transport clusters; by comparing the first cluster list with A second cluster list stored locally determines that there is a new transport cluster.

The cluster management server is the server that manages the transport cluster. The first cluster list is a list of transport clusters that are currently providing streaming data transport services on the cluster management server. The second cluster list is a list of transport clusters that provide streaming data transport services stored locally at the client. The client downloads from the cluster management server to the local device, and then compares the first cluster list with the second cluster list. If there is an identifier of the transport cluster that is not in the second cluster list in the first cluster list, it is determined that there is a new transport cluster.

In an embodiment of the present invention, preferably, the method further includes: if the target transmission cluster that has been deleted is determined by comparing the first cluster list with the locally stored second cluster list, deleting the locally saved The communication configuration code corresponding to the target transmission cluster.

The target transport cluster is a transport cluster that no longer serves streaming data transfers. Comparing the first cluster list and the second cluster list, if there is an identifier of the transport cluster that is not in the first cluster list in the second cluster list, it is determined that there is a deleted target transport cluster. Delete the communication configuration code corresponding to the target transport cluster saved locally by the client.

In an embodiment of the present invention, preferably, the method further includes: updating the second cluster list by using the first cluster list of the cluster management server.

Downloading the first cluster list from the cluster management server, comparing the first cluster list and the second cluster list, updating the second cluster list with the first cluster list, specifically deleting the second cluster list, and saving the first cluster list to Locally as a new second cluster list, or add the new content in the first cluster list to the local second cluster list, or delete the content deleted in the first cluster list from the local second cluster list.

In an embodiment of the present invention, preferably, the communication configuration code further records a network address of the newly added transmission cluster, and an implementation manner of sending the encapsulated scheduling request to the newly added transmission cluster is: And sending the encapsulated scheduling request to the newly added transport cluster according to the network address of the newly added transport cluster indicated by the communication configuration code.

The network address of the newly added transport cluster is the domain name address of the calling transport cluster, and the network address is resolved and the access can send the encapsulated scheduling request to the transport cluster corresponding to the network address. Specifically analyzing the network address of the newly added transport cluster indicated by the communication configuration code may obtain the address of the server for scheduling the transport node, and then send the encapsulated scheduling request to the server.

In the embodiment of the present invention, after the determining that there is a newly added transmission cluster, the method further includes: acquiring a cluster identifier of the newly added transport cluster; and downloading a corresponding one in the slave communication configuration code base. Before the communication configuration code, the corresponding communication configuration code may be searched from the communication configuration code base according to the cluster identifier of the newly added transmission cluster.

After determining that there is a new transport cluster, the client obtains the cluster ID of the newly added transport cluster. For example, the cluster identifier of the newly added transport cluster can be obtained from the list of transport clusters. For example, the cluster identity of the newly added transport cluster can be extracted from the first cluster list.

Before downloading the corresponding communication configuration code from the communication configuration code base, the communication configuration code corresponding to the cluster identifier can be searched from the communication configuration code base according to the cluster identifier.

In the embodiment of the present invention, it is determined that the communication configuration code of a certain transmission cluster is updated. Specifically, by comparing the code corresponding to the transmission cluster in the communication configuration code base with the locally stored code, it is found that the communication configuration code is updated, and the communication is performed. The corresponding code in the configuration code base can be updated to the local. For example, it is possible to directly compare whether the code corresponding to the transport cluster in the communication configuration code base and the code corresponding to the locally stored transport cluster are the same to determine whether the communication configuration code of the transport cluster is updated. Alternatively, whether the communication configuration code of the transport cluster is updated may be compared according to whether the version number of the code corresponding to the transport cluster in the communication configuration code base is the same as the version number of the code corresponding to the locally stored transport cluster.

Further, the updated communication configuration code is downloaded from the communication configuration code base, and the updated communication configuration code may be used for the transmission of the streaming data, specifically, when the transmission cluster in which the communication configuration code is updated is called, the preset interpreter is used to interpret and perform the update. Obtaining a communication configuration code, wherein the communication configuration code performs encapsulation of the scheduling request of the transmission node according to the communication protocol of the transmission cluster, sends the encapsulated scheduling request to the transmission cluster, and then performs streaming data according to the transmission node scheduled by the transmission cluster. transmission. In general, when a vendor modifies the way in which a scheduling request is transmitted to a cluster, although the old scheduling request is generally compatible at this time, the new method generally has success rate, accuracy, efficiency, and security. Other aspects have certain advantages.

2 is a schematic flowchart of a step of a scheduling method of a transit node according to Embodiment 2 of the present invention, which may specifically include the following steps:

In step 201, the streaming data transmission client is started.

In this embodiment, the streaming data transmission client may be a client that uploads streaming data to the transport cluster, or a client that downloads streaming data from the transport cluster, for example, in a live video application, uploading an anchor of the video stream data. The client, the viewer client that downloads the video stream data.

In step 202, it is determined that there is a new transmission cluster.

In this embodiment, after the streaming data transmission client is started, it is detected whether there is a new transmission cluster, and the detection result is that the new transmission cluster is determined. The specific manner is consistent with the description of other embodiments, and details are not described herein.

Step 202: Download a corresponding communication configuration code from the communication configuration code base.

In the embodiment, the specific manner is the same as the description of other embodiments, and details are not described herein.

Step 204: Send a stream data transmission request to the cluster scheduling server, and receive a feedback result of the scheduling new transmission cluster fed back by the cluster scheduling server.

The cluster scheduling server is a server that can schedule a transmission cluster for the client. Specifically, the client can select a transmission cluster and feed back to the client according to the stream data transmission request of the client. The cluster scheduling server can be a single server or one of the cluster scheduling server clusters. The cluster scheduling server can be the same server as the cluster management server or another server different from the cluster management server.

In this embodiment, the streaming data transmission client sends a streaming data transmission request to the cluster scheduling server, where the streaming data transmission request usually carries the network address of the client and/or the current location, so as to select the cluster scheduling server as the client. The basis for the transport cluster. The stream data transmission client receives the feedback result of the cluster scheduling server, wherein the feedback result is a scheduling result of scheduling the newly added transmission cluster, specifically including a transmission cluster selected for the client, and may further include a stream data identifier allocated for the stream data. In this embodiment, the cluster scheduling server is configured as a new transmission cluster for the transmission cluster scheduled by the client according to the transmission request of the client, and the client receives the feedback result of the cluster scheduling server.

Step 205: When the newly added transport cluster is invoked, the preset interpreter is used to interpret and execute the communication configuration code, and the communication configuration code performs encapsulation of the scheduling request of the transport node according to the communication protocol of the newly added transport cluster. .

In this embodiment, the specific manner of the step is the same as that of the other embodiments. For the sake of brevity, no further details are provided herein.

Step 206: Send the encapsulated scheduling request to the newly added transport cluster.

Step 207: Receive a scheduling result that is fed back by the newly added transmission cluster.

In this embodiment, the scheduling result of the newly added transmission cluster feedback is the transmission node in the scheduled transmission cluster, and specifically, the newly added transmission cluster schedules a transmission node in the transmission cluster according to the encapsulated scheduling request, where The scheduling result encapsulates information such as the node identifier of the scheduled transmission node. The transport cluster may allocate a transport node to the client according to the network address and/or location of the client, and may also allocate a transport node to the client according to load balancing among multiple transport nodes, and may adopt any applicable scheduling manner. This embodiment does not limit this. The new transmission cluster sends the scheduling result generated by the scheduling to the client, and the client receives the scheduling result.

Step 208: Interpreting and executing the communication configuration code by using a preset interpreter, and parsing, by the communication configuration code, the new transmission cluster scheduling from the scheduling result according to the communication protocol of the newly added transmission cluster. The node ID of the transport node.

The node identifier is an identifier of the transit node in the network, and may specifically be an identifier of the transport node in the transport cluster or a network address of the transport node, such as an IP address. The preset interpreter is used to interpret and execute the communication configuration code, and the scheduling result is parsed according to the communication protocol of the newly added transmission cluster, and the node identifier of the scheduled transmission node is parsed from the scheduling result.

For example, the Lua language universal interpreter is used to interpret and execute the communication configuration code corresponding to the newly added transmission cluster, and the communication configuration code is executed to implement parsing of the IP scheduling result data packet received by the client. Specifically, the content included in the data packet of different transmission cluster IP scheduling results is different. Some transmission clusters agree that the result of the scheduling data packet is the identifier of the stream data directly after the network address of the transmission node, and the specific string, and some transmissions The cluster contract scheduling result packet is a network address of the transport node in a custom format, an identifier of the stream data, and a specific string.

Step 209: Perform stream data transmission according to a transport address of the transport node corresponding to the node identifier.

In an embodiment, the transport address is a network address used for streaming data transmission, and may be combined into a transport address by a protocol corresponding protocol header of the stream data transmission, a network address of the transport node, an identifier of the stream data, and an agreed specific string.

The corresponding transport node can be found by the node identifier, and the transport address can be generated on the client according to the content parsed from the scheduling result, or can be directly parsed from the scheduling result. The client accesses the transport address and transmits the stream data to the transport node.

In summary, according to the embodiment of the present invention, by starting the streaming data transmission client, determining that there is a new transmission cluster, downloading a corresponding communication configuration code from the communication configuration code base, so that when the new transmission cluster provides the streaming data transmission service When the corresponding communication configuration code is directly downloaded, the scheduling function of the newly added transmission cluster is added to the client without applying the application update.

Then, the system sends a stream data transmission request to the cluster scheduling server, and receives the feedback result of the scheduling new transmission cluster fed back by the cluster scheduling server, so as to implement the request scheduling distribution transmission cluster. When the newly added transmission cluster is invoked, the communication configuration code is interpreted and executed by using a preset interpreter, and the communication configuration code performs encapsulation of the scheduling request of the transmission node according to the communication protocol of the newly added transmission cluster, and The encapsulated scheduling request is sent to the newly added transmission cluster, and the scheduling result fed back by the newly added transmission cluster is received, and the communication configuration code is interpreted and executed by using a preset interpreter, and the communication configuration code is added according to the new Transmitting a communication protocol of the cluster, parsing, from the scheduling result, a node identifier of the transmission node scheduled by the newly added transmission cluster, and transmitting the stream data according to the transmission address of the transmission node corresponding to the node identifier. The execution communication configuration code can complete encapsulation of the scheduling request corresponding to the newly added transmission cluster, and then be used to schedule the node to schedule the transmission node, complete the analysis of the scheduling result of the feedback of the transmission cluster, and then obtain the scheduled transmission node, and implement the new The hot update of the scheduling function of the transmission cluster avoids the inconvenience and inconvenience of updating the application.

Referring to FIG. 3, a schematic flowchart of a step of a scheduling method of a transit node according to Embodiment 3 of the present invention is shown, which may specifically include the following steps:

Step 301: The cluster scheduling server prestores a configuration relationship between the location information of the client and the at least one transport cluster.

The cluster scheduling server is configured to schedule the transport cluster, select one transport cluster among the multiple transport clusters and feed back to the requester, for example, to schedule the transport cluster for the client that issues the cluster scheduling request.

In this embodiment, different transport clusters belong to different transport service providers, and transport service providers refer to transport network providers that provide transport clusters with service stream data transmission. Specifically, any applicable supplier may be selected, and this embodiment does not limit this.

The location information of the client may be information indicating a location area to which the client belongs or geographically belonged to the network, and may include an address segment corresponding to the network address and/or a geographical area corresponding to the location, where the network address (Network) Address) is the logical address that a node on the Internet has in the network. For example, the IP address (English: Internet Protocol Address, also translated as Internet Protocol address). The location information is location information obtained by the client by using the location service. For example, the client invokes geographic location information obtained by Global Positioning System.

In this embodiment, the cluster scheduling server may pre-store the configuration relationship between the location information of the client and the at least one transport cluster, where the configuration relationship is a correspondence between the location information and the at least one transport cluster, and is used according to the location of the client. The information allocates a corresponding transport cluster to the client to provide a streaming data transmission service. For example, the configuration relationship may be a correspondence between a network address segment and at least one transport cluster, or a correspondence between a geographic region and at least one transport cluster.

The pre-stored configuration relationship may be any applicable configuration relationship that is manually set, or may be configured to analyze the configuration relationship of each transport cluster for different location areas according to historical data, and may be any applicable configuration relationship. This is not a limitation.

Specifically, there may be multiple transmission clusters corresponding to one location information, and multiple transmission clusters may be recorded. The prior ranking indicates that the transmission performance is better, and may be used as the preferred transmission cluster.

Step 302: The cluster scheduling server corrects the configuration relationship according to the transmission performance data of the transmission cluster of each transmission service provider.

The transmission performance data is performance data when the client and the transmission cluster perform streaming data transmission, and specifically includes a code rate, a frame rate, and the like when the stream data is transmitted. The transmission performance data of the transmission cluster may be data collected by at least one client during streaming data transmission, and the transmission performance data of each transmission cluster obtained by synthesizing data reported by multiple clients.

In this embodiment, the transmission performance data of the transmission cluster of each transmission service provider is obtained by each client periodically, for example, the code rate when the client periodically reports the stream data transmission, and the client user selection or client. The frame rate of the video stream data that is switched according to the network status.

The cluster scheduling server determines the transmission performance data of each location information corresponding to each transmission cluster according to the location information carried by each client when transmitting the performance data, because the same transmission cluster is for different geographical areas, that is, for different location information, the transmission performance The data will be different. As time changes, the transmission performance data of each transmission cluster corresponding to each location information will also change. The configuration relationship is corrected according to the transmission performance data of each transmission cluster.

Specifically, the modified configuration relationship may be a transmission cluster corresponding to one location information, modified to a transmission cluster with the best transmission performance data, or reordered each transmission cluster according to the transmission performance data, and the sorted transmission cluster. The order corrects the configuration relationship.

In this embodiment, preferably, the transmission performance data carries a client identifier and a transmission cluster identifier corresponding to a transmission process, and the configuration relationship is performed according to transmission performance data of a transmission cluster of each transmission service provider. One implementation of the modification is: the cluster scheduling server collects transmission performance data of multiple clients corresponding to the same location information to the same transmission cluster, and calculates an average value; the cluster scheduling server compares whether the average value reaches a set threshold. Or correct the configuration relationship between the location information and the transport cluster by comparing the same location information to the average of different transport clusters.

The client identifier refers to the identifier of the client that uploads the transmission performance data, and the transport cluster identifier refers to the identifier of the transport cluster to which the client that transmits the transmission performance data is connected.

Each client periodically reports the transmission performance data to the cluster scheduling server, and the reported transmission performance data carries the client identifier and the transmission cluster identifier of the transmission process corresponding to the transmission performance data, and reports the location information of the client in the corresponding transmission process. According to the location information reported by the client, the transmission performance data of multiple clients corresponding to the same location information to the same transmission cluster is found, and the average value of the transmission performance data is calculated, and multiple clients corresponding to each location information are obtained in this manner. The transmission performance data of each transmission cluster is collected and the average value is calculated separately.

The cluster scheduling server corrects the configuration relationship between the location information and the transport cluster. Specifically, it can compare whether the average value reaches the set threshold. If the average value is set, the corresponding configuration of the transport cluster and the location information can be used to update the configuration. Relationship; or the relationship between the location information and each transport cluster may be updated by comparing the average values of different transport clusters corresponding to the same location information according to the ranking of the average values.

In step 303, it is determined that there is a new transmission cluster.

In this embodiment, the client is the first client, and the specific manner of the step is the same as that of the other embodiments. For the sake of brevity, no further details are provided herein.

Step 304: Download a corresponding communication configuration code from the communication configuration code base.

Step 305: The cluster scheduling server schedules the corresponding first transmission cluster for the first client according to the modified configuration relationship.

In this embodiment, the first client requests to allocate a transport cluster for the stream data transmission, and the server according to the modified configuration relationship, the cluster scheduling server finds the corresponding first transport cluster according to the location information of the first client.
