Background technology
P2P (Peer-to-Peer, be called for short P2P) be a kind of distributed network, the participant of network shares a part of hardware resource (disposal ability, storage capacity, network concatenation ability, printer etc.) that they are had, these shared resources need provide service and content by network, can directly be visited by other peer node (Peer) and need not through intermediate entities.Participant in this network is resource (service and content) supplier (Server), is again that resource (service and content) obtains taker (Client).The P2P technology has been broken traditional Client/Server (C/S) pattern, and the status of each node in network all is reciprocity.Each node had both served as server, for other nodes provide service, also enjoyed the service that other nodes provide simultaneously.
The P2P live streaming media is a kind of network flow-medium broadcast mode that latest development is got up, it utilizes the principle of P2P to set up playing network, adopt " peer broadcast " (Peer casting) technology of P2P, be that each player uses reciprocity threaded file P2P shareware, realize to the user network distributing contents.Program file is broken down into a lot of little fragments, and each user's download is stored the butt joint exchange mutually again of some fragments, and each user obtains complete copy at last.
But because data object is to be distributed in randomly in each on-fixed individual node (or claiming on-fixed peer node, i.e. normal client end), because distance is irregular between the node ID, so the load of some node may be several times of system's average load.Therefore, caused the node load of whole P2P network unbalanced, i.e. the ability of load of node and node does not conform to.
Hence one can see that, and current P2P network all is that on-fixed individual node constitutes except server, and whole P2P network is close with the individual node relationships of on-fixed.Because the client in the current P2P network is not the client of extended immobilization substantially, thereby causes the P2P network fluctuation, has increased the burden of server and client, and cause each on-fixed individual node load unbalanced.
Summary of the invention

Embodiment
The present invention is on the basis of existing P2P platform, disposed the accelerator client in advance by adjacent locations at the normal client end, semifixed widely (" semifixed " is meant that the accelerator client is fixing the deployment thereby set up, but allow in the P2P network to have a plurality of accelerator clients for you to choose) the accelerator client bring in and stablize the P2P network, the user can extract its needed data from the accelerator client of closing on, the Internet resources that leave unused that close in the network domains have been made full use of, reduce the server network flow, accelerated the speed that the user obtains data simultaneously.
For making purpose of the present invention, technical scheme and advantage clearer, below by specific embodiment and referring to accompanying drawing, the present invention is described in detail.
Shown in Fig. 1 is the system architecture diagram that makes up half-fixed P 2 P network.As shown in the figure, comprise the P2P server, quicken server, a plurality of accelerator client (accelerator client 1 ... accelerator client n) and a plurality of normal client end (client 1 ... client n).
Wherein, the accelerator server is used to manage the normal operation of a plurality of accelerator clients, and the accelerator client is carried out authentication, receives the service data that the accelerator client reports; The accelerator client has the function of normal client end, and main being responsible for reports service data to the accelerator server, and provides a plurality of downloaded resources simultaneously to the user; The P2P server is used to preserve the information of user's download resource, comprises the seed of downloaded resources and the situation of current active user's download.
Below with reference to the accelerator workflow diagram shown in Fig. 2, and describe for example, may further comprise the steps in conjunction with Fig. 1:
Step S200: at first, the accelerator client signs in to the accelerator server.The accelerator client has been added accelerator authentication function on the basis of normal client end.
Because allow to exist a plurality of accelerator clients in the P2P network,, be convenient to the normal operation of a plurality of accelerator clients energy, so the accelerator client need sign in to the accelerator server for the ease of managing a plurality of accelerator clients.
Step S205: the accelerator server is verified the identity of accelerator client, to confirm whether the user has the right to use the accelerator client functionality.The purposes of quickening server mainly is to be used for managing the accelerator client, comprises the checking to the login of accelerator client.
Step S210: after the login authentication of accelerator client is passed through, and expression is logined successfully.
Step S215: after the accelerator client was logined successfully, user's (can be a plurality of users) just can select the resource (as the network direct broadcasting program) that oneself needs to quicken download by its normal client end from the accelerator client.
What the accelerator client was different with the normal client end is, the accelerator client is that predetermined fixed is disposed, and often needs onlinely for the user provides service, is equivalent to a fixing superclient end.When the accelerator client deployment on ordinary PC or server, this accelerator client can be moved by unattended operation automatically, under the situation of acquiescence, this accelerator client can select 3 P2P resources the most popular (as the QQLIVE program) to download automatically.The accelerator client itself has the function of common P2P node.Owing to be generally unattended operation, thereby can continually provide data on flows to other normal client ends that needs.
Wherein, the normal client end of this step S215 and the data interaction between the accelerator client as shown in Figure 3, this data exchange process may further comprise the steps:
Step S300: if user's (by its normal client end) needs downloaded resources (as the QQLIVE program), and (" seed " is the address to first source file when the user obtains the seed of current downloaded resources, refer to the complete file link on the P2P platform, other user can find automatically by this document and the client that this document downloads is provided and downloads), these seeds can be by the user by logining described P2P server or by being got access to by the P2P server broadcast.And according to these seeds, the user just can preferentially obtain the IP address of accelerator client, because long-term when online when the accelerator client in the P2P network, its IP is preferential.Like this, user's (by its normal client end) just can sign in to the accelerator client.
Certainly, accelerator client and normal client end all need to sign in to the P2P server earlier before, so that obtain downloaded resources (as QQLIVE the rendition list), user's (by its normal client end) just can obtain downloaded resources there from the accelerator client like this.But the accelerator client is a plurality of, a plurality of accelerator clients can be simultaneously from the P2P server downloaded resources; And an accelerator client also can be downloaded a plurality of resources for one or more users provide simultaneously.
Need to prove that in the existing P 2P mode, the user also can be from another normal client end there downloaded resources by its normal client end.So the normal client end also needs to sign in to the P2P server and downloaded resources from the P2P server.
Therefore, the user is when downloaded resources, generally directly do not download from P2P server and/or normal client end, but can be downloaded by preferential, the near accelerator client of having disposed of distance fast to those speed according to the seed of the current downloaded resources that obtains, and the while can also be downloaded a plurality of resources (as a plurality of QQLIVE programs) there.
Step S305, S310, S315: the user is according to obtaining the Resources list that current needs downloaded resources selects needs to download (the QQLIVE program of watching as needs).The user can download a plurality of resources simultaneously from an accelerator client.But an accelerator client also can be a plurality of users (being a plurality of normal client ends) service simultaneously.
Wherein, the data of all downloaded resources on the accelerator client all leave in its internal memory, have avoided like this causing hard disk corruptions because of the hard disc data of the frequent directly visit of user accelerator client.
Need to prove: because memory size is limited, so relatively be fit to the download (as the QQLIVE program) of the program data of network direct broadcasting aspect.And need big capacity downloaded files data for the user, because its data volume is big, then can only leave in the hard disk.
Normal client end and accelerator client are directly carried out in the reciprocal process, and accelerator is brought in respect to normal client and said so transparently, generally is not used in and play-overs program.
Therefore, for the accelerator client, the data of its output are many more, effect is just good more, the flow of P2P server and pressure have been alleviated relatively (because can not need P2P server there downloaded resources, but directly arrive accelerator client there downloaded resources), also accelerated the speed that the user obtains data simultaneously.
Step S220, S225: when the user continues quickening in the client in the downloaded resources process, the accelerator client needs regularly to report service data to the accelerator server, this service data comprises the flow of download/upload in the unit interval, user's linking number (promptly having how many users to download) or the like.Be convenient to the management of accelerator server to the accelerator client like this, over-burden to avoid a certain accelerator client, helps flow equalization.
The above only is preferred embodiment of the present invention, and in order to restriction the present invention, within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc.All should be included within protection scope of the present invention.
