Description

A method and device for peer-to-peer P2P resource transmission

technical field

The present invention relates to the communication field, in particular to a method and device for peer-to-peer (Peer-to-Peer, P2P) resource transmission.

Background technique

Peer-to-peer computing refers to the process of sharing computer resources and services and processing information through direct exchange between different systems. Here, resources may be processors, caches, and disk space, etc., and services include information exchange, data calculation, etc. The key difference between the P2P mode and the traditional client access resource server mode is that the node (Peer) can abandon the role of the resource server during the communication process, and complete the direct communication between nodes to obtain shared resources or services.

In the P2P system, each node is an equal participant, taking on two roles of service user and service provider. The ownership and control of resources are distributed to every node in the network. Direct communication between service users and service providers can make full use of network bandwidth, reduce network congestion, and greatly improve the effective utilization of resources including various computing resources and storage resources. At the same time, because there is no centralized control of the central node, the scalability of the system is strong, and it can also avoid single point failures and improve the fault tolerance of the system.

P2P networks include 3 different structures, namely centralized P2P, fully distributed P2P and hybrid P2P. Centralized P2P requires all nodes to log in to the central server, and the central server saves and maintains the shared file directory information of all peers; distributed P2P adopts a completely distributed information sharing technology, and each node acts as a server. It is also a client. Each node only knows the nodes directly connected to it. If other nodes do not respond to the node's ping or reply to the query, this node will not see other nodes.

The hybrid P2P network combines the advantages of centralized and distributed P2P networks, and has been further optimized in terms of design ideas and processing capabilities. The interaction between nodes in the network is mainly divided into the interaction between the node and the directory server (Tracker) and the interaction between nodes: the resource requesting node sends a request to the tracker to obtain a list of resource providing nodes with the required content; Nodes exchange their own content information, not only as a resource request node to obtain downloaded content from other nodes, but also as a resource provider node to upload its own resources to other nodes.

With the rapid development of the mobile Internet, P2P software has begun to be applied on mobile terminals. And with the continuous development of mobile networks and the subsequent deployment of 4G wireless networks, mobile terminal P2P clients will be widely used, and more and more mobile terminals will participate in P2P resource interaction.

However, the current method of P2P resource transmission does not consider the impact of wireless terminal nodes on the network and P2P service performance, and cannot reasonably select nodes located in the wireless network as resource providing nodes to provide resources. The performance of the P2P service that the nodes of the network participate in is relatively low.

Contents of the invention

Please refer to FIG. 3a, which is a flowchart of a P2P resource transmission method provided by another embodiment of the present invention. In the application scenario of this embodiment, resource request nodes, directory servers and information servers are included. The resource requesting node may be a network terminal located in a wired or wireless network. The method includes:

Step S31, the directory server sends a request for obtaining reference information to the information server.

In an implementation of this embodiment, when a resource requesting node wishes to download a resource, the resource requesting node first sends a resource request to the directory server. The directory server stores a list of resource providing nodes that own the resource. In order to obtain reference information for selecting a resource providing node that owns the resource, the directory server sends a request for obtaining reference information to the information server. The request for obtaining reference information contains a list of resource provider nodes that own the resource. The information server receives the request for obtaining reference information sent by the directory server.

In another implementation of this embodiment, the directory server may first send the request for obtaining reference information back to the resource requesting node, and then the resource requesting node forwards the request for obtaining reference information to the directory server.

Step S32, the information server obtains the wireless state information of the resource providing node located in the wireless network according to the request for obtaining reference information.

In an implementation of this embodiment, the information server obtains the wireless state information of each resource providing node in the reference information request according to the obtaining reference information request, and the wireless state information is used to indicate the state and /or the resource provides the status of the wireless network where the node is located. The wireless wireless state information of the resource providing node may be acquired from an OAM (Operation Administration and Maintenance, operation management and maintenance) server.

In an implementation of this embodiment, the wireless status information of the resource providing node includes cell distribution topology information of the network where the resource providing node is located, status information of the cell where the resource providing node is located, and node status information of the resource providing node. at least one of . The status information of the cell where the resource providing node is located is used to indicate the load status of the cell where the resource providing node is located, and the node status information of the resource providing node is used to indicate the ability of the resource providing node to provide resources. The cell distribution topology information of the network where the resource providing node is located indicates the distribution of cells and/or base stations of the wireless network. The above three types of information included in the wireless status information of the resource providing node will all affect the ability of the resource providing node to upload resources to the resource requesting node. Therefore, preferably, the wireless status information includes cell distribution topology information of the network where the resource providing node is located, status information of the cell where the resource providing node is located, and node status information of the resource providing node. Certainly, the above three kinds of information are only exemplary, and the wireless state information in this embodiment is not limited to the above three kinds of information.

In another implementation of this embodiment, the cell distribution topology information of the network where the resource providing node is located includes the distance between the cell where the resource providing node is located and the cell where the resource requesting node is located; the status information of the cell where the resource providing node is located Including at least one parameter of cell resource utilization, cell user access probability, and access success rate; the node status information of the resource providing node includes the resource providing node’s mobility rate, center-edge attributes, user priority, battery power and At least one parameter in the access capability. The parameters included in each of the above information are exemplary, and each of the information may also include other parameters.

The cell distribution topology information of the network where the resource provider node is located can be obtained directly from the OAM server, and the complexity of obtaining the cell distribution topology information is far from It is lower than the complexity of obtaining network topology information in a wired network.

The cell resource utilization rate may include power resource utilization rate, and code resource utilization rate in the case of WCDMA system or RB (ResourceBlock, resource block) resource utilization rate in the case of LTE system. The cell resource utilization rate, cell user access probability and access success rate can be obtained directly from the OAM server.

The mobility rate, center-edge attribute, user priority, battery power and access capability can be obtained directly from the OAM server, RNC (Radio Network Controller, radio network controller) or evolved base station (eNB). Among them, the center-edge attribute is used to indicate whether the user is a center user or an edge user. Specifically, the user can be judged according to the user's path loss, SINR (Signal to Interference plus Noise Ratio, signal to interference and noise ratio) or RSRP (Reference signal received power, reference symbol received power) and other information. The center edge property of .

In another implementation of this embodiment, the wireless state information of the resource providing node is a state information weighted result obtained by weighting various types of information according to preset state information weights, and the various types of information may include the The cell distribution topology information of the network where the resource providing node is located, the status information of the cell where the resource providing node is located, and the node status information of the resource providing node. Specifically, the information server may first obtain the various types of information, and then weight the various types of information according to formula (1):

Peer_Value=Value_cellmap*Va+Value_cell*Vb+Value_UE*Vc...Formula (1)

Peer_Value represents the weighted result of the state information, Value_cellmap represents the value of the cell distribution topology information of the network where the resource provides the node, Value_cell represents the value of the state information of the cell where the resource provides the node, Value_UE represents the value of the node state information of the resource providing node, Va, Vb, and Vc are respectively the cell distribution topology information of the network where the resource providing node is located, the state information of the cell where the resource providing node is located, and the state information weights corresponding to the node state information of the resource providing node.

In another implementation manner of this embodiment, each type of information may be a weighted result of multiple parameters included in the information. Specifically, the information server may weight the parameters included in each type of information according to formula (2):

Value_cellmap=V1*v1+V2*v2+...+Vn*vn

Value_cell=V1'*v1'+V2'*v2'+...+Vn'*vn'...Formula (2)

Value_UE=V1"*v1"+V2"*v2"+...+Vn"*vn"

V1, v2, ..., vn provide the resource with the weight of each parameter contained in the cell distribution topology information of the network where the node is located, and V1, V2, ..., Vn provide the resource with the cell distribution topology information of the network where the node is located The value of each parameter included; v1', v2', ..., vn' is the weight of each parameter contained in the state information of the cell where the resource provides the node, V1', V2', ..., Vn' Provide the value of each parameter contained in the state information of the cell where the node is located for the resource; v1", v2", ..., vn" provide the weight of the parameters contained in the node state information of the node for the resource, V1", V2 ", ..., Vn" provides the value of the parameter contained in the node status information of the node for this resource. For example, in this implementation, the cell distribution topology information of the network where the resource providing node is located includes the distance parameter between the cell where the resource providing node is located and the cell where the resource requesting node is located; the status information of the cell where the resource providing node is located includes The weighted results of resource utilization, cell user access probability, and access success rate parameters; the node status information of the resource providing node includes the weighted results of mobility rate, center-edge attributes, user priority, battery power, and access capability parameters. After that, the information server calculates the Peer_Value according to the formula (1).

Step S33 , the information server sends the wireless state information to the directory server, so that the directory server selects the resource providing node according to the wireless state information, and generates a resource providing node recommended for the resource requesting node to use.

In an implementation of this embodiment, the information server sends the wireless state information to the directory server, and the directory server selects a resource providing node that meets the requirements as a recommended resource for the resource requesting node according to the wireless state information providing node, and sending the selected recommended resource providing node to the resource requesting node. In another implementation of this embodiment, the information server first sends the wireless state information to the resource requesting node, and then the resource requesting node forwards the wireless state information to the directory server, and the directory server transmits the wireless state information according to the wireless State information, select a resource providing node that meets the requirements as a recommended resource providing node recommended for the resource requesting node.

In an implementation of this embodiment, if the wireless state information of the resource providing node includes the cell distribution topology information of the network where the resource providing node is located, the resource requesting node may be preferentially selected according to the cell distribution topology information of the network where the resource providing node is located The resource provider node in the cell or the same station cell is the recommended resource provider node, and then uses local switching to obtain the required resources.

In another implementation of this embodiment, if the wireless state information of the resource providing node includes the load status of the cell where the resource providing node is located, the resource providing node in the cell with a lower load is preferentially selected as the recommended resource providing node. node.

In another implementation of this embodiment, if the wireless status information of the resource providing node includes the node status information of the resource providing node, the resource providing node with better ability to provide resources is preferentially selected as the recommended resource providing node , such as selecting a resource provider node with a faster upload rate as the recommended resource provider node. For example, if the node state information of the resource providing node includes the mobile rate, the channel environment of the terminal with too high mobile rate changes rapidly, which may cause large rate fluctuations, and at the same time cause frequent switching, which may cause P2P communication failures. Therefore, the resource provider node with a lower mobile rate is preferred. For another example, if the node status information of the resource providing node includes the user's center-edge attribute, since the center user can obtain a higher uplink rate, the resource providing node of the center user is preferentially selected. For another example, if the node status information of the resource providing node includes user priority, since the user priority indicates the user's QoS (Quality of Service, Quality of Service) attribute in the wireless network, under the same circumstances, users with high priority can preferentially obtain wireless resources, so the resource provider node with high user priority is selected. For another example, if the node state information of the resource providing node includes the battery power of the user, then the resource providing node with sufficient battery power of the user is preferentially selected. For another example, if the node status information of the resource providing node includes user access capability information, then if the user has multiple access capabilities, such as WIFI (Wireless Fidelity, Wireless Fidelity), D2D (Device to Device), etc., it is preferred to select A resource providing node with access capability.

If the wireless state information of the resource providing node contains more than one kind of information, the recommended resource providing node can be selected by referring to the multiple kinds of information together according to a predetermined strategy. Similarly, if any one of the various types of information contains more than one parameter, the recommended resource providing node can be selected by referring to the multiple parameters together according to a predetermined strategy.

In another implementation of this embodiment, if the wireless state information of the resource providing node is the state information weighted result obtained by weighting various types of information according to the preset state information weight, then the directory server according to the The wireless state information selects the resource providing node, and generating a resource providing node recommended for the resource requesting node is: selecting a resource providing node whose weighted result of the state information is better than a preset threshold, or selecting a resource providing node from the resource requesting node A predetermined number of optimal resource providing nodes are selected from the state information weighted results as recommended resource providing nodes.

Specifically, set a threshold Peer_Value_threshold, compare the Peer_Value of each resource providing node with the Peer_Value_threshold, if the Peer_Value of a resource providing node is lower than the Peer_Value_threshold, then the resource providing node cannot be used as a recommended resource providing node; if If there are multiple resource providing nodes whose Peer_Value is not lower than the Peer_Value_threshold, then according to the number of required resource providing nodes, select the resource providing node with better Peer_Value value as the recommended resource providing node. Alternatively, a predetermined number N may also be set, and the top N resource providing nodes with the best Peer_Value are selected as recommended resource providing nodes.

Step S32': Obtain policy information and/or capability information according to the request for obtaining reference information, wherein the policy information is used to indicate the network use policy set by the network provider; the capability information is used to indicate the network provider service capabilities.

The information server also acquires policy information and/or capability information according to the request for acquiring reference information. The policy information is used to indicate the network usage policy set by the network provider. For example, some network providers may block P2P networks, while some network providers' policy is to allow P2P applications to use network resources. There are other network policies: such as business flow control policies, fine-grained or extensive link usage policies, and so on.

The capability information is used to indicate the service capability of the network provider. For example, the network provider may provide different levels of resource servers in the network, and the information server can provide these resource servers as resource providing nodes to accelerate P2P.

In the case of having step S32', the method of this embodiment utilizes step S33' to replace step S33 in the embodiment corresponding to Fig. 3a:

In an implementation of this embodiment, the resource requesting node wishes to download a resource, and the information server receives a request for obtaining reference information sent by the resource requesting node, and the request for obtaining reference information includes a list of resource providing nodes owning the resource. If there is a directory server, the list of resource providing nodes that own the resource can be obtained from the directory server in advance by the resource requesting node; if there is no directory server, the resource requesting node is based on a distributed hash table (DistributedHashTable, DHT) By performing distributed resource search, the list of resource providing nodes that own the resource can be obtained.
