Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present application provides a method for acquiring a resource, which specifically includes the following steps:
s101, the user terminal node sends a target resource acquisition request to a signaling server.
Wherein the target resource refers to a resource required by the user terminal node. And the resource may specifically be a video resource, an audio resource, a file resource, a picture resource, and the like. The user terminal node may be a cell phone node, a tablet node, a computer node, etc. The signaling server may be any one of the signaling servers in the signaling cluster, or may be a pre-designated signaling server. In the process of executing step S101, the user terminal node may send an acquisition request of the target resource to the signaling cluster, and a signaling server in the signaling cluster receives the acquisition request of the target resource sent by the user terminal node.
The acquisition request of the target resource may carry identification information of the target resource, so as to inform the signaling server of which target resource is required by the signaling server. The acquisition request of the target resource is mainly used for informing the signaling server that the user terminal node needs to acquire the target resource. Specifically, the request for obtaining the target resource may be a request for playing a target video resource, a request for playing a target audio resource, a request for browsing a target picture resource, and the like.
Optionally, in an actual application scenario of step S101, the ue node is connected to the signaling cluster through a Transmission Control Protocol (TCP), and sends the acquisition request of the target resource to the signaling cluster, where the signaling server in the signaling cluster receives the acquisition request of the target resource.
S102, the signaling server determines node information corresponding to the acquisition request of the target resource.
The node information corresponding to the acquisition request of the target resource includes: node information of the target terminal node and node information of the relay terminal node. The node information corresponding to the acquisition request of the target resource is the node information of the terminal node that enables the user terminal node to acquire the target resource. The target terminal node is a terminal node with target resources. The relay node is a terminal node for acquiring the target resource from the target node and then transmitting the target resource to the user node. The node information of the target end node is information that needs to be used when establishing a P2P connection with the target end node, and may be, for example, IP address information of the target end node. Similarly, the node information of the relay terminal node is information that is required to be used when establishing the P2P connection with the relay terminal node, and may be, for example, IP address information of the relay terminal node.
The signaling server can know which target resource the user terminal node needs to acquire from the received acquisition request of the target resource. The target terminal node and the relay terminal node can be determined for the user terminal node. The target terminal node has the target resource which the user terminal node wants to acquire. Through the node information of the target terminal node, the user terminal can establish P2P connection with the target terminal node and acquire the target resource from the target terminal node. Unlike the target terminal node, the relay terminal node does not own the target resource, but the user terminal node can indirectly acquire the target resource from the target terminal node by establishing a P2P connection with the relay terminal node.
Because the P2P connection between the target terminal node and the user terminal node fails, in the prior art, in order to enable the user terminal node to obtain the target resource, the user terminal node is enabled to obtain the target resource from the CDN server when the P2P connection fails, which results in too much bandwidth consumed by the CDN server and fails to meet the requirement of reducing the bandwidth cost of the server.
In the embodiment of the present application, the node information corresponding to the request for acquiring the target resource, which is determined by the signaling server for the user terminal, includes the node information of the relay terminal node in addition to the node information of the target terminal node. Although the relay terminal node does not own the target resource unlike the target terminal node, the user terminal node can indirectly acquire the target resource from the target terminal node by establishing P2P connection with the relay terminal node. Therefore, when the P2P connection between the target terminal node and the user terminal node fails, the target terminal node may indirectly acquire the target resource from the target terminal node by establishing the P2P connection with the relay terminal node. The CDN server is not used in the process, so that the bandwidth consumed by the CDN server is reduced, and the requirement for reducing the bandwidth cost of the server can be met.
Optionally, referring to fig. 2, in an embodiment of the present application, an implementation of step S102 is performed, including:
s201, the signaling server requests the scheduling server to acquire the node information corresponding to the acquisition request of the target resource.
The node information corresponding to the acquisition request of the target resource includes: node information of the target terminal node and node information of the relay terminal node.
Optionally, the signaling server may use the identification information of the target resource carried in the acquisition request of the target resource received in step S101 to invoke the scheduling server, and the scheduling server acquires the node information corresponding to the acquisition request of the target resource by using the identification information of the target resource.
Alternatively, the signaling server may directly utilize the acquisition request of the target resource acquired in step S101 to generate a request for acquiring node information corresponding to the acquisition request of the target resource and send the request to the scheduling server. The request for acquiring the node information corresponding to the request for acquiring the target resource carries identification information of the target resource. After receiving the request for acquiring the node information corresponding to the acquisition request of the target resource, the scheduling server acquires the node information corresponding to the acquisition request of the target resource by using the identification information of the target resource.
S202, the scheduling server searches node information of the terminal node with the target resource from the data background, and selects the node information of the target terminal node from the searched node information of the terminal node with the target resource.
The data background stores the current resource information and node information of each terminal node. The resource information of the terminal nodes and the node information are specific, and each terminal node reports the resource information of the terminal nodes to the data background according to a preset time interval. The resource information of the terminal node is used for explaining the resources owned by the terminal node. Alternatively, the resource information of the terminal node may include identification information of each resource owned by the terminal node.
The scheduling server can search and find out the node information of the terminal node with the target resource from the data background by using the identification information of the target resource, then select one of the found terminal nodes with the target resource as the target terminal node, and obtain the node information of the target terminal node from the data background. Optionally, from the searched node information of the terminal node having the target resource, one terminal node may be arbitrarily selected as the target terminal node, or the terminal node closest to the user terminal node may be selected as the target terminal node.
S203, the scheduling server searches out the node information of the terminal nodes meeting the functional requirements of the relay terminal nodes from the data background, and selects the optimal node information of the relay terminal nodes from the searched node information of the terminal nodes meeting the functional requirements of the relay terminal nodes.
The relay terminal node function requirement can be set according to the theoretical success rate of the terminal node for establishing the P2P connection. Specifically, the relay terminal node function requirement may be a terminal node which does not have a target resource locally and has a theoretical success rate of establishing the P2P connection that meets a preset requirement. When the terminal node meets the functional requirements of the relay terminal node, the theoretical success rate of establishing P2P connection between the terminal node and other terminal nodes is higher and is superior to most terminal nodes, so that the terminal node is suitable to be selected as the relay terminal node. Optionally, the theoretical success rate of establishing the P2P connection by the terminal node may be obtained by evaluating at least one of a current load state of the terminal node, a P2P penetration theoretical value of a router used by the terminal node, and whether the terminal node is a public network IP address.
For example, the terminal node that meets the functional requirement of the relay terminal node may be a terminal node that meets at least one of the conditions that a public network IP address is used, a P2P penetration theoretical value of a used router is higher than a penetration threshold, and the number of terminal nodes currently connected by the terminal node (i.e., a load state) is lower than a connection node threshold, that is, when at least one of the conditions that a public network IP address is used, a P2P penetration theoretical value of a used router is higher than a penetration threshold, and the number of terminal nodes currently connected by the terminal node (i.e., a load state) is lower than a connection node threshold is considered to be met, the theoretical success rate of establishing P2P connection by the terminal node meets a preset requirement.
Optionally, in a specific embodiment of the present application, the optimal relay terminal node is obtained by selecting an optimal relay terminal node selection policy. The optimal relay terminal node selection strategy is set through at least one of a selection index of the current load state of the terminal node, a selection index of a P2P penetration theoretical value of a router used by the terminal node and a selection index of whether the terminal node is a public network IP address.
When there are a plurality of pieces of node information of the terminal nodes that satisfy the functional requirements of the relay terminal node, it is necessary to select the optimal node information of the relay terminal node from the plurality of pieces of node information of the terminal nodes that satisfy the functional requirements of the relay terminal node. The optimal relay terminal node is the terminal node with the highest theoretical success rate for establishing the P2P connection. And the optimal relay terminal node selection strategy makes a rule for selecting the terminal node with the highest theoretical success rate (namely the optimal relay terminal node).
Specifically, the theoretical success rate of establishing the P2P connection by the terminal node using the public network IP address is higher than that by the terminal node not using the public network IP address, and the higher the theoretical value of the P2P penetration rate of the router used by the terminal node is, the higher the theoretical success rate of establishing the P2P connection by the terminal node is. The lower the load of the terminal node is, the higher the theoretical success rate of the terminal node for establishing the P2P connection is. The optimal relay terminal node selection strategy can stipulate that the terminal node which uses the public network IP address and uses the router with the highest P2P penetration rate theoretical value is the optimal relay terminal node. It can also be specified that the lowest loaded terminal node using the public network IP address is the optimal relay terminal node.
It should be noted that, the search for the terminal node that meets the functional requirement of the relay terminal node is performed in all terminal nodes that do not own the target resource, so the selected optimal relay terminal node is also the terminal node that does not own the target resource.
Optionally, each terminal node may report, according to a preset time interval, each current index for evaluating the theoretical success rate of P2P connection to the data background, and the data background updates and stores the current index. After the signaling server requests the scheduling server to acquire the node information corresponding to the acquisition request of the target resource, the signaling server can find out the terminal nodes which can meet the functional requirements of the relay terminal nodes by looking up each index of each terminal node which does not have the target resource and is used for evaluating the theoretical success rate of the P2P connection.
Optionally, in a specific embodiment of the present application, node information of all terminal nodes that meet the functional requirements of the relay terminal node may also be stored in the data background in advance, then any terminal node is directly selected from the node information as the relay terminal node, and the node information of the relay terminal node is carried in the node information corresponding to the request for obtaining the target resource, which is mentioned in step S204.
It should be noted that the execution sequence of step S202 and step S203 does not affect the implementation of the embodiment of the present application.
S204, the scheduling server returns the node information corresponding to the acquisition request of the target resource to the signaling server.
The node information corresponding to the acquisition request of the target resource includes: node information of the target terminal node and node information of the relay terminal node. The node information of the relay terminal node in the node information corresponding to the request for acquiring the target resource is obtained through the selection in step S203. The node information of the target terminal node in the node information corresponding to the acquisition request of the target resource is obtained by selecting in step S202.
S103, the signaling server returns the node information corresponding to the acquisition request of the target resource to the user terminal node.
S104, if the user terminal node fails to request the establishment of the P2P connection with the target terminal node by using the node information of the target terminal node, the user terminal node requests the establishment of the P2P connection with the relay terminal node by using the node information of the relay terminal node, and requests the relay terminal node to acquire target resources from the target terminal node.
After receiving the node information corresponding to the acquisition request of the target resource returned by the signaling server, the user terminal node firstly uses the node information of the target terminal node to request to establish P2P connection with the target terminal node. If the P2P connection between the user terminal node and the target terminal node is not successfully established, it indicates that the user terminal node has no way to directly obtain the target resource from the target terminal node, and therefore the user terminal node needs to indirectly obtain the target resource through the relay terminal node.
Specifically, the node information of the relay node is used to establish a P2P connection with the relay terminal node, and to request the relay terminal node to acquire the target resource from the target terminal node. When the relay terminal node is requested to acquire the target resource from the target terminal node, the node information of the target terminal node and the identification information of the target resource are sent to the relay terminal node, so that the relay terminal node can clearly determine which target resource needs to be acquired from which terminal node.
Optionally, in a specific embodiment of the present application, an implementation manner of performing step S104 includes:
the user terminal node requests the relay terminal node to forward the acquisition request of the target resource to the target terminal node, so that the relay terminal node sends the acquisition request of the target resource to the target terminal node.
After the relay terminal node and the target terminal node successfully establish the P2P connection and send the acquisition request of the target resource to the target terminal node, the target terminal node can return the target resource to the relay terminal node.
Optionally, in a specific embodiment of the present application, the method further includes:
and if the user terminal node successfully establishes the P2P connection with the target terminal node by using the node information of the target terminal node, sending an acquisition request of the target resource to the target terminal node, and acquiring the target resource returned by the target terminal node.
Optionally, in a specific embodiment of the present application, the method further includes:
and if the user terminal node fails to establish the P2P connection with the relay terminal node by using the node information of the relay terminal node, requesting the CDN server to acquire the target resource and receiving the target resource returned by the CDN server.
In order to ensure that the user terminal node can acquire the target resource, under the condition that the P2P connection between the user terminal node and the relay terminal node is failed, the user terminal node selects to request the CDN server to acquire the target resource and receives the target resource returned by the CDN server.
And S105, the relay terminal node acquires the target resource from the target terminal node.
Specifically, the relay terminal node may obtain the node information of the target terminal node from the request in step S104. And then establishing P2P connection with the target terminal node by using the node information of the target terminal node, and then sending an acquisition request of the target resource to the target terminal node to obtain the target resource returned by the target terminal node.
And S106, the relay terminal node returns the target resource to the user terminal node.
And the target resource returned by the relay terminal node is obtained from the target terminal node by the relay terminal node. Specifically, the relay terminal node transmits the target resource to the user terminal node, and the user terminal node downloads the video from the relay terminal node.
The following describes a resource acquisition process based on the method shown in fig. 1 by using a specific embodiment. Referring to fig. 3, firstly, user a locally holds the file1 video and the file2 video, but does not have the file3 video, and when the terminal node of user a wants to play the file3 video, step 1 is executed to request the signaling cluster service to view the file3 video. And the signaling server in the signaling cluster service executes the step 2 to check which nodes hold the file3 video from the scheduling cluster service, and the scheduling server in the scheduling cluster service executes the step 3 to return the nodes holding the file3 video (namely the terminal nodes of the user B) and the nodes capable of serving as relays (namely the terminal nodes of the user C meeting the functional requirements of the relay terminal nodes) to the signaling cluster service. And the signaling server in the signaling cluster service executes step 4 to return the node information of the terminal node of the user B and the node information of the terminal node of the user C to the terminal node of the user A. And the terminal node of the user A executes the step 5 to establish P2P connection to the terminal node of the user B and requests to acquire the local file3 video of the terminal node of the user B. If the P2P connection between the user A and the user B fails, the terminal node of the user A executes the step 6 again to request the user C to download the file3 video from the user B. The terminal node of the user C executes the step 7 to forward the request message sent by the user A to the user B, then the user B executes the step 8 to return the file3 video sent to the user A to the user C, and the user C executes the step 9 to return the file3 video to the user A. In the process, although the P2P connection between the user a and the user B fails to be established, the user B cannot be successfully requested to return the file3 video to the user a, the user a can indirectly request the file3 video from the user B through the relay node of the user C, and then the user B transfers the file3 video to the user a through the user C, so that the user a is guaranteed to acquire the file3 video. In the whole process of acquiring the video, the CDN server is not required to process the video, and the bandwidth of the CDN server is not consumed.
According to the resource acquisition method provided by the embodiment of the application, after the user terminal node sends the acquisition request of the target resource to the signaling server, the user terminal node can receive the node information corresponding to the acquisition request of the target resource, which is returned by the signaling server. The node information corresponding to the acquisition request of the target resource includes: node information of the target terminal node and node information of the relay terminal node. And then the user terminal node may, under the condition that the node information of the target terminal node is utilized to request the target terminal node to establish the P2P connection, utilize the node information of the relay terminal node to establish the P2P connection with the relay terminal node, request the relay terminal node to acquire the target resource from the target terminal node, and further acquire the target resource returned by the relay terminal node. The target resource returned by the relay terminal node is obtained from the target terminal node by the relay terminal node, and the target terminal node is a terminal node with the target resource. Compared with the mode that the video resources are obtained through the CDN server under the condition that the establishment of the P2P connection with the target terminal node is requested to fail in the prior art, the target resources can be obtained from the target terminal node through the relay terminal node under the condition that the CDN server is not used, the bandwidth consumed by the CDN server is reduced, and the requirement for reducing the bandwidth cost of the server is met.
