Description
Technical Field

background
Peer-to-Peer (P2P) is a distributed network where participants in the P2P network share a portion of their own hardware resources (processing power, storage power, network connectivity, printers, etc.) that need to be served and content by the network, and that can be accessed directly by other Peer nodes (peers) without going through intermediate entities. Participants in this network are both resource (service and content) providers (server) and resource (service and content) acquirers (client).
the P2P model is often used in scenarios where video or audio material is shared (e.g., video resource downloads for websites such as audio and video). When each network node shares resources, the resources are usually stored on each network node in the form of a file, and the file is split into a plurality of sub-files and transmitted to the opposite node. Since the conventional P2P technology generally transfers data in a file-based manner, the file needs to be prepared in advance, and thus, the application scenarios are limited, for example, the P2P technology cannot be applied to the transmission of real-time video stream in live mode.

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Fig. 1 is a network architecture proposed in an embodiment of the present application, and the network architecture includes a server device 100 and client devices (110, 120, 130), and the client devices are built with each other through the server device to form a P2P network. Since the functional requirements of the network device may be different for users in different application environments, the number and functions of the servers and the client devices may be different in each application scenario.
In order to enable the P2P network of the embodiment of the present application to break through the conventional transmission mode of the conventional P2P network (i.e. transmit data between peer nodes in a manner of splitting files in the conventional technology), the present application proposes the following technical solutions, and fig. 2 is a partial step:
After the shared resource is split into a plurality of data packets (S200), the server packages the data packets according to a self-defined format (S201); the self-defined format comprises a first identifier, and the first identifier is used for describing the uniqueness of each data packet;
The server sends the encapsulated data packet to each client (S202);
after the server notifies each client to establish a P2P network (S203), the client interacts the data packet with other clients based on the pre-agreed transmission policy and the first identifier (S204).
in the embodiment, the shared resource refers to a resource that needs to be shared to each peer node, and it should be noted that the shared resource is not limited to file data in a file form (for example, common audio/video files, picture files, various Office documents, and the like), and is also applicable to streaming media data, for example, live data in a live scene, and the like.
Unlike the conventional P2P mode, in the embodiment, when S200 is executed, the shared resource is first cut into data packets instead of file blocks, the size of the file blocks may be hundreds of KB, but the packet size is smaller than the file blocks, and the data packets can be transmitted in the network as smaller transmission units, for example, when the size of the cut data packets is considered, the data packets can be designed by combining the transmission characteristics of the internet link layer, so that the size of the data packets matches the transmission bandwidth of each connection channel in the P2P network. For example, the channel established between each pair of peer nodes may be a UDP channel, and the size of each packet may be about 1KB, which is approximately equal to MTU (maximum transmission unit of internet link layer), so that each packet may be transmitted by 1 UDP packet without unpacking based on the UDP packet, which is more efficient than a file splitting method, thereby having a wider application scenario.
The server that is the subject of the execution of S201 may be assumed by various entities depending on the division of roles of different network devices by the designer. For example, fig. 3a, fig. 3b, and fig. 3c are network architectures in three different scenarios, and it can be seen that, in different service modes, due to different requirements of service or device management, different server devices may undertake the execution subject of step S201. In fig. 3a, a first server takes on the role of collecting shared resources, a second server takes on the role of splitting packets, and a third server takes on the role of distributing packets to peers. In fig. 3b, the first server integrates the functions of collecting shared resources and splitting packets, and the second server acts as the server for distributing packets. In fig. 3c, the server integrates the functions of collecting shared resources, splitting data packets, and distributing data packets. It is noted that other forms of network architecture or server functionality than the examples listed in fig. 3a, 3b, 3c are not excluded.
in the data encapsulation phase of S201, in order to enable the split data packets to be sequentially assembled after being received by the clients and to interact with the data packets after peer nodes are formed between the clients, the server may number each data packet as a field describing a unique identifier of each data packet, where the unique identifier is a first identifier, and in some examples, the purpose may be achieved by customizing a format of the data packet, and a specific field may be specified in the customized format as the unique identifier. In some examples, the first identifier proposed in the present application may be a unique identifier for distinguishing other data packets in the same shared resource. Of course, other ways of achieving this are not excluded. As an example, exchanging data packets between clients may mean that after some clients send out a message requesting some numbers, the clients that have downloaded the number data packets may send the data packets to the requesting party in response to the request. Since the clients are in equal-position roles (i.e., peer nodes) in the P2P network, a requester at a certain time can become a responder at the next time, and therefore, the packet interaction between the clients in the P2P network can be bidirectional, not necessarily unidirectional.
In stage S202, in some examples, the server may send the data packet to each client in order to widely spread the data packet among the peers in the P2P network so that the peers can transmit the data packet to each other. Of course, the designer may set different delivery policies for different service scenarios, for example, the server may send only some of the designated clients. In one example, the client may make an active request to the server to inform the server of the identity of the shared resource (e.g., in a live scenario, similar to the conventional technique in which the client informs the server of the identity of the required live stream), and the server determines to which clients to send the data packet based on the identity of the shared resource.
when S203 constructs the P2P network, the way of establishing the connection path may be different in different application instances. For example, some examples may be implemented with reference to the way in which a peer node in a P2P network in the prior art establishes a UDP channel; in other examples, a new flow may be designed for the actual scenario. For example, all clients initiate a registration request to the server, and notify the server of some information related to the shared resource and information necessary for establishing a connection (e.g., a network connection address, a port number, etc.), which may be carried in the registration request or sent to the server in other messages. The server informs which clients need to establish network connection to form the peer node based on the information related to the shared resources. By way of example, this application refers to some information about the shared resource as a second identifier, which is used to describe the uniqueness of the shared resource. In the example of fig. 7b, which is a flow of establishing a network connection in a live scenario, it can be seen that in this example, the server aggregates viewer clients watching the same channel into a P2P network by using the identity of the live broadcast room (e.g. channel number, live stream identity, etc.) as a second identity. In other instances, various modifications to the specific flow may still be made.
the server notifies each client of the opportunity of constructing the P2P network, which is not limited in the present application, and may notify each client after the server receives the second identifier, or notify each client after transmitting a data packet to the client for a period of time. As an example, the relevant control policy may be issued to the client when the server issues the configuration information to the client, or of course, the relevant control policy may be set in the client in advance. Still taking the live broadcast scenario as an example, in some examples, the client enters a certain channel, and sends the control policy for establishing the P2P network to the client when requesting the configuration information related to the channel from the server, and in some examples, when the client registers with the server, the server sends the control policy for establishing the P2P network to the client.
Any peer node in the network may request packets from other peer nodes, and at stage S204, the peer node may request packets from other peer nodes based on the first identifier and a pre-agreed transmission policy, which may specify which identified packets may be propagated in the P2P network. As an example, in a live broadcast scenario, in order to ensure the requirement of fast playing video stream, the transmission policy may specify that the viewer client first obtains the data packet from the server within a predetermined time, then queries the server whether there is a client corresponding to the second identifier, and if so, requests the other clients for the data packet
In some examples, in order to prevent some peers from accessing a certain P2P network by mistake, the peers may also carry a second identifier to check the identity of the peer in the P2P network when exchanging data packets.

other steps executed by the client may refer to descriptions of other parts in this application, and are not described again.
Since the present application is applicable to a variety of resource sharing scenarios, for convenience of understanding, a few application examples are listed below.
Fig. 6 is a network environment using a manufactured video file as a shared resource. The network architecture formed by the network devices can be described by taking an example that one server integrates multiple functions with reference to fig. 3 c.
In this example, a server having a cloud storage function, such as a network disk, may be used to take on the role of the server.
s601, the server stores a video file, wherein the video file can be static data stored on the server or uploaded to the server by a certain client.
s602, several clients register with the server to notify their respective network connection information such as IP addresses and port numbers.
S603, the server divides the video file into data packets, and encapsulates the data packets according to a user-defined format, wherein each encapsulated data packet carries the number of the data packet as a first identifier.
s604, when the client b, c requests the server for the video file, the server informs the client to establish the P2P network according to the identification of the video file.
and S605, the server respectively sends the data packets with the first identification to the clients b and c.
s606, the client side b and the client side c receive the data packets sent by the server and request the data packets with the assigned numbers to other peer nodes according to the prearranged transmission strategy.
And S607, downloading and storing the data packets received by the client sides b and c.
s608, when the client side b and c need to read the video file, the data packets are recombined into the video file according to the first identifier.
The newly accessed client d requests the server for the video file, and the server informs the client d to establish a P2P connection with the clients b and c according to the file name of the video file. The client d requests the data packets with the specified numbers from other peer nodes in the P2P network according to the prearranged transmission strategy. And the client b and the client c send each data packet obtained by segmenting the video file to the client d. When the client d judges that the data packet with a certain number is lacked according to the first identifier, the data packet is broadcasted in the P2P network again. And after receiving the request, the client b and the client c send the data packet corresponding to the number to the client d. And when the client d needs to read the video file, recombining the data packets into the video file according to the first identifier.
fig. 7a is a network environment in a live scenario. In the network of fig. 7a, a TCP connection channel is established between the anchor client and the live server, the live server is connected to the slicing server, and the slicing server is connected to the CDN server. Referring to fig. 7b, a signaling interaction diagram of a network device in a live broadcast scenario is specifically as follows:
S701 registers a stage for the viewer client.
when the audience client registers to the live broadcast server, the live broadcast server is informed of the IP address of the local terminal equipment, the port number of the client and the concerned channel number.
In S702, the live broadcast server forwards the live broadcast video stream sent by the anchor client to the slice server, where the live broadcast video stream carries the corresponding video stream identifier.
in S703, the slicing server cuts the live video stream into 1 KB-sized data packets, and packages each data packet in a customized format after numbering the data packet.
In S704, the encapsulated packet is sent to the CDN server by the slicing server.
in S705, the audience client requests the CDN to obtain a live video stream to be acquired, and the CDN server sends an assigned data packet to the audience client according to a preset transmission policy.
S706 is a stage of establishing P2P channel.
in order to ensure the timeliness of live data playing, after the CDN server sends the data packet to the client for a period of time, the live server notifies the viewer client who concerns the same channel number to establish a P2P connection channel according to the channel number. In this example, in order to ensure the viewing effect of the live video stream, after the CDN server sends a video block to each client for a period of time, each viewer client may establish a P2P network.
after receiving the data packets of the CDN for a period of time, the viewer clients mutually establish a P2P network according to the channel number notified by the live server.
