Description

A resource sharing method and device

technical field

The present invention relates to the field of communication technologies, and in particular, to a resource sharing method and device.

Background technique

A peer-to-peer (P2P) network is a networking mode in which different network participants share computer resources and services through peer-to-peer direct communication. At present, P2P is widely used in content services such as downloading, live video, and on-demand. In a P2P network, nodes find the neighbor node where the target resource is located by sending control messages, and initiate a request to obtain the target resource to the neighbor node. P2P networks are mainly used in wired networks with sufficient bandwidth resources and low latency.

At present, the specific method for realizing resource sharing based on the P2P network is: the user terminal directly requests the predetermined target user terminal for shared resources. Obviously, the premise of realizing this method is that the user knows which target user terminal stores the shared resources that he needs. Under the premise that it is impossible to know which target user terminal stores the shared resources that it needs, if the shared resource request information is sent blindly, it is likely to cause the request to fail, which not only wastes network resources, but also makes it impossible to obtain the required shared resources or The efficiency of acquiring shared resources is low; obviously, the success rate of resource sharing in this way is low.

A wireless mesh network (mesh network) is a multi-hop network structure composed of mesh routers (routers) and user terminals. Among them, mesh routers form the backbone network and are connected to the wired Internet (internet). , responsible for providing multi-hop wireless internet connections for user terminals. The embodiment of the present invention utilizes the wireless network to provide a P2P content service, so as to realize the requirement of sharing resources between terminals.

The basic implementation process includes: the first user terminal sends the shared resource search request information to the first router covering the first user terminal; the first router searches for the shared resource information of each user terminal under the coverage, and searches for the shared resource information from each user terminal that can provide If the user terminal of the shared resource requested by the first user terminal is found, the information of the found user terminal is sent to the first user terminal, and the first user terminal is instructed to obtain the information from the found user terminal. shared resources. It can be seen that since the first router maintains the shared resource information of multiple user terminals under the coverage, it can search for the first user terminal from the multiple user terminals for the target user terminal that can provide the shared resources required by the first user terminal. Compared with the way in which the first user terminal blindly sends requests to other user terminals, not only the success rate of finding the required shared resources for the first user terminal but also the efficiency of finding the shared resources can be improved.

The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Example 1

As shown in FIG. 1, a flowchart of a resource sharing method provided in Embodiment 1 of the present invention includes the following steps:

S101: The first router receives the shared resource search request information sent by the first user terminal.

In this step, the first router is a router closest to the first user terminal, and is also a router that provides a wireless Internet (internet) connection for the user terminal. The first router is responsible for storing the information of each shared resource that the first user terminal can use to share, such as resource identification information, and is responsible for providing the first user terminal with a target user terminal that can provide the first user terminal with related shared resources. information, such as the identification information of the target user terminal.

S102: Based on the shared resource information of each covered user terminal, the first router searches for a target user terminal that can provide the shared resource requested by the first user terminal from the user terminals.

In a specific implementation, the first router may maintain a user terminal list, which includes identification information of each user terminal and information of shared resources (such as a certain video name) that each user terminal can use to share. Each user terminal performs information registration on the first router, and provides information on the shared resources that can be provided by the terminal; when each user terminal changes the shared resources that can be provided by itself, it also informs the first router of the shared resource change information. router.

In this step, the first router searches for the shared resources that the first user terminal needs to obtain from each user terminal according to the information about the shared resources that the first user terminal needs to obtain indicated in the shared resource request information sent by the first user terminal. The target user terminal of the resource.

S103: If the first router finds a target user terminal that can provide the shared resource requested by the first user terminal from the user terminals, send the information of the found target user terminal to the first router A user terminal, instructing the first user terminal to acquire the shared resource from the found target user terminal.

In this step, the first router sends the found identification information of the target user terminal to the first user terminal, and the first user terminal requests the required shared resources from the target user terminal according to the identification information and based on the P2P method. If no target user terminal that can provide the shared resources required by the first user terminal is found among the user terminals covered by the first router, a search failure message may be returned to the first user terminal, or Embodiments 2 to 4 may be used. way to search further.

Embodiment 2

In the second embodiment, in addition to maintaining the shared resource information (user terminal list) of each user terminal within its own coverage, the first router also maintains a second router list, including identification information of each second router and each second router. Information on shared resources provided by user terminals covered by routers, the distance between the second router and the first router in the list is less than or equal to the first distance threshold, indicating the distance between the second router and the first router More recently, the transmission delay of P2P content transmission between the user terminal covered by the first router and the user terminal covered by the second router is relatively small. The first router and the second router may periodically exchange information, and notify each other of information about shared resources that can be provided by user terminals under their respective coverages.

As shown in FIG. 2 , a flowchart of a resource sharing method provided in Embodiment 2 of the present invention includes the following steps:

S201: The first router receives the shared resource search request information sent by the first user terminal.

S202: Based on the shared resource information of each covered user terminal, the first router searches for a target user terminal that can provide the shared resource requested by the first user terminal from the user terminals, and if found, goes to S203, otherwise Enter S204.

S203: The first router sends the found information of the target user terminal to the first user terminal, and instructs the first user terminal to acquire the shared resource from the found target user terminal.

S204: Based on the shared resource information of each user terminal covered by the second router, the first router searches for a target user terminal that can provide the shared resource requested by the first user terminal from each user terminal covered by the second router, and The distance between the second router and the first router is less than or equal to a first distance threshold.

S205: If the first router finds a target user terminal capable of providing the shared resource requested by the first user terminal from the user terminals covered by the second router, then find the target user terminal covered by the found second router The information of the user terminal is sent to the first user terminal, and the first user terminal is instructed to acquire the shared resource from the found target user terminal.

In S204-S205, if the first router does not find a target user terminal capable of providing the shared resources required by the first user terminal among the user terminals covered by itself, it searches the second router list maintained by itself to search Whether there is a target user terminal that can provide the shared resources required by the first user terminal in the user terminals covered by each second router, and if found, the identification information of the target user terminal covered by the second router can be notified. to the first user terminal. If no target user terminal that can provide the first user terminal with the shared resources required by the user terminal under the coverage of the second router is found, a search failure message may be returned to the first user terminal, or Embodiment 3 or The method of the fourth embodiment is further searched.

Embodiment 3

Because the local storage capacity of the user terminal is limited, the shared resources provided are limited. When the first user terminal cannot obtain the shared resources in the adjacent user terminals, if the first user terminal obtains the shared resources from the distant user terminal, the transmission delay will increase. Based on this , in the third embodiment, one or more edge content servers are deployed in the vicinity of each router. The first router maintains a list of edge content servers, which may include identification information of each edge content server and information of shared resources that each edge content server can provide. When there is no target user terminal capable of providing shared resources for the first user terminal in the user terminals covered by the first router and the second router, in order to ensure that the first user terminal obtains the shared resources in time, the edge content server can be used for The first user terminal provides shared resources, thereby improving the server quality for the first user terminal. After acquiring the shared resource from the edge content server, the first user terminal can provide the shared resource for other user terminals, thereby reducing the service requests that the edge content server needs to process. The edge content server obtains shared resources from the source server (central content server) that provides shared resources, and they can be connected through wired or wireless connections.

As shown in FIG. 3 , a flowchart of a resource sharing method provided in Embodiment 3 of the present invention includes the following steps:

S301: The first router receives the shared resource search request information sent by the first user terminal.

S302: Based on the shared resource information of each covered user terminal, the first router searches for a target user terminal that can provide the shared resource requested by the first user terminal from the user terminals, and if found, goes to S303, otherwise Enter S304.

S303: The first router sends the found information of the target user terminal to the first user terminal, and instructs the first user terminal to acquire the shared resource from the found target user terminal.

S304: Based on the shared resource information of each user terminal covered by the second router, the first router searches for a target user terminal that can provide the shared resource requested by the first user terminal from each user terminal covered by the second router; The distance between the second router and the first router is less than or equal to the first distance threshold, if found, go to S303, otherwise go to S305.

S305: Based on the shared resource information of each edge content server of the first router, the first router searches for an edge content server that can provide the shared resource requested by the first user terminal from the edge content servers of the first router ; The distance between any edge content server of the first router and the first router is within a set distance range;

Here, the edge content server of any router refers to an edge content server whose distance to any router is within a set distance range.

S306: If an edge content server capable of providing the shared resource requested by the first user terminal is found from the edge content servers of the first router, send information about the found edge content server to the first router A user terminal, instructing the first user terminal to acquire the shared resource from the found edge content server.

In this step, if the first router finds an edge content server that can provide the shared resource requested by the first user terminal from its own edge content servers, it sends the identification information of the found edge content server to the said edge content server. A first user terminal, where the first user terminal sends, based on the identification information of the edge content server, request information for acquiring a required shared resource to the edge content server corresponding to the identification information, and the edge content server is based on the shared resource information in the request information, For example, the shared resource identification information is used to provide the first user terminal with related shared resources.

Embodiment 4

The difference from Embodiment 3 is that if neither the user terminals covered by the first router nor the second router can provide the shared resources required by the first user terminal, only the first user terminal that contributes more shared storage space will first Consider providing services through the edge content server to improve its service quality; and for the first user terminal that contributes less shared storage space, first consider whether the user terminal covered by the third router farther away can provide it Shared resources, after the user terminals covered by the third router that are far away from it cannot provide shared resources for them, the edge content server is considered to provide services for them, compared with the first consideration of the way to provide services through the edge content server The delay for the first user terminal to acquire the shared resource is increased. In this way, the user terminal can be encouraged to contribute more storage space for storing shared resources.

In the case that the edge content server still cannot provide the shared resource, it is obtained from the source server that provides the shared resource, that is, the central content server. The central content server exists as a content source, and each resource server provider uploads the shared resources to the central content server.

In this way, in addition to the user terminal list, the second router list, and the edge content server list, the information maintained in the first router also maintains a third router list, which includes the identification information of each third router and the third router list. Information about shared resources that can be provided by each user terminal under the coverage of the router.

S404: Based on the shared resource information of each user terminal covered by the second router, the first router searches for a target user terminal that can provide the shared resource requested by the first user terminal from each user terminal covered by the second router, and The distance between the second router and the first router is less than or equal to the first distance threshold; if found, go to S403, otherwise go to S405.

S405: The first router searches for priority information of the first user terminal, where the priority information is used to indicate that the first user terminal is a high-priority user terminal or a low-priority user terminal, wherein the high-priority user terminal The shared storage space is larger than the shared storage space of the low-priority user terminal; after determining that the first user terminal is a high-priority user terminal, enter S407, otherwise (determine that the first user terminal is a low-priority user terminal) , and enter S406.

In a specific implementation, the user terminal list stored by the first router also includes priority information of each user terminal covered by the first router. Correspondingly, the stored second router list also includes each user terminal covered by the second router. User terminal priority information. The priority information here can be information indicating the priority type of the user terminal, such as indicating that the user terminal is a high-priority user terminal or a low-priority user terminal, or it can be an implicit indication, such as storing the user terminal’s In the shared storage space information, if the shared storage space of the user terminal is larger than the preset storage space size, the user terminal is determined to be a high-priority user terminal; otherwise, the user terminal is determined to be a low-priority user terminal.

S408: The first router sends the found information of the edge content server to the first user terminal, and instructs the first user terminal to acquire the shared resource from the found edge content server.

S409: The first router sends the information of the central content server to the first user terminal, and instructs the first user terminal to acquire the shared resource from the central content server.

Optionally, in this step, if the first router does not find an edge content server that can provide the shared resource requested by the first user terminal from the edge content servers of the first router, it notifies the Each edge content server of the first router acquires the shared resource from the central content server, and sends to the second router indication information that the edge content server needs to store the shared resource, to instruct the second router to notify the second router Each edge content server of the router obtains the shared resources from a central content server; the central content server is a source server that provides various shared resources.

In the specific implementation process, the first router notifies the edge content server of the first router to cache the shared resources when neither the user terminal covered by it nor the second router list can retrieve the shared resources required by the first user terminal, and notifies the second router to cache the shared resources. The routers in the router list need to cache the shared resource, and the routers in the second router list notify their respective edge content servers to cache the shared resource. In this way, after the edge content server acquires and caches the shared resource from the central content server, when other user terminals need to acquire the shared resource subsequently, these edge content servers can quickly provide the shared resource for adjacent user terminals.
