Description
Technical field
The present invention relates to areas of information technology, relate in particular to P2P resource downloading method and recognition device.
Background technology
Peer-to-peer network (Peer to Peer is called for short P2P) technology is by directly exchange a kind of application model of shared resource and service between network element.In the P2P network configuration, the status of each node all is identical, has the dual-use function of client and server simultaneously, can be simultaneously as the user and the supplier that serve.
In recent years, with BT (BitTorrent), Emule etc. is that the P2P of representative uses and to have obtained develop rapidly, development based on instant messaging, Streaming Media and the internet ip phone of P2P is also very rapid, P2P is applied in and has surpassed the Web application in the fixed the Internet, has occupied more than 50% of fixed the Internet flow.In present mobile Internet environment, be subjected to the restriction of network and terminal, mobile P 2 P is used also and is not realized, but, along with mobile network's continuous development and evolution, and the continuous enhancing of portable terminal disposal ability, P2P technology and business will extend in the mobile Internet gradually.P2P can be divided into four kinds of forms according to topological structure: centralized configuration (Napster), full distributed non-structure (Gnutella), full distributed architecture (based on DHT) and half distributed frame (having Super Node).
Be example with Napster below, introduce the P2P operation principle.Napster has adopted centralized LIST SERVER mechanism.LIST SERVER is left the address information of peer node and the information of the data of preserving concentratedly, can search and return only destination node fast to request msg.Actual file transmission will directly be carried out between requesting node and destination node.Fig. 1 is the schematic diagram of Napster structure P2P system works principle in the prior art.As shown in Figure 1, its workflow comprises: 1. client A is to LIST SERVER query aim resource addresses; 2. LIST SERVER returns target resource address client B to client A; 3. client A and client B connect; 4. client A obtains target resource from client B.Therefore, Napster structure P2P technology has realized separating of file polling and file transfer, has saved the bandwidth consumption of central server effectively, has reduced the file transfer time-delay of system.
In mobile network's P2P uses, should have the service level identical with the fixed network access to the client.Fig. 2 is the schematic diagram based on the mobile Internet logical construction of GPRS/EDGE/WCDMA.As shown in Figure 2, grouping domain network element mainly comprises: Serving GPRS Support Node (Serving GPRS Support Node, abbreviation SGSN), Gateway GPRS Support Node (Gateway GPRS Support Node, abbreviation GGSN), base station controller (BaseStation Controller, be called for short BSC) and radio network controller (Radio NetworkController is called for short RNC) etc.
SGSN is a GSM/GPRS/EDGE server network element as the important component part of packet domain equipment.It mainly finishes functions such as the generation of routing forwarding, mobile management, session management, Logical Link Management, authentication and the encryption of packet data package and ticket and output.SGSN links to each other with BSC by Gb Interface, and main effect is that the MS to this SGSN coverage carries out mobile management, and transmits the IP grouping of I/O.In addition, stored among the SGSN with grouping relevant user profile and positional information.Insert (Universal Terrestrial Radio Access is called for short UTRAN) by Iu-PS interface and global terrestrial radio and link to each other, the functions such as routing forwarding, mobile management of packet domain mainly are provided.
GGSN is a GSM/GPRS/EDGE server network element as the important component part of packet domain equipment.It mainly provide with the interface of SGSN, with external packet data net (Packet Data Network, be called for short PDN)/external public land mobile communication network (PublicLand Mobile-communication Network, abbreviation PLMN) interface, have Route Selection and forwarding information function, can be provided to the route and the protocol conversion that reach correct SGSN.GGSN is divided into two kinds of situations according to the network difference that is connected, and a kind of is to be connected with another PLMN network, and a kind of is to be connected with PDN, and the interface that dual mode adopted is the Gi interface.At evolved packet system (Evolved Packet System, abbreviation EPS) in the network architecture, the function of GGSN develops into gateway (Serving Gateway is called for short S-GW) and PDN Gateway (PDN Gateway, be called for short PDN-GW), S-GW and PDN-GW are collectively referred to as SAE-GW.Wherein S-GW is the gateway towards eNodeB termination S1-U interface, the major function that can provide has: the reordering function of also assisting to finish eNodeB when switching between eNodeB as local anchor point, at third generation partner program (3rd Generation PartnershipProject, mobility anchor point when abbreviation 3GPP) switching between different access systems, the route of Lawful intercept and packet and preceding commentaries on classics, according to each subscriber equipment (User Equipment, be called for short UE), the up link of PDN and QCI and the relevant charging of down link etc.; PDN-GW is the gateway that ends in the S_Gi interface towards PDN.If UE visits a plurality of PDN, UE is with the one or more PDN-GW of correspondence.The major function that PDN-GW provides the S5/S8 based on GTP and PMIP has the packet filtering based on the user, Lawful intercept, the IP address assignment of UE, in up link, carry out packet transport level mark, the up-downgoing grade of service is chargeed and the control of service level thresholding and based on the control of the up-downgoing speed of business.Simultaneously PDN GW only also provides the major function based on the S5/S8 interface of GTP the uplink downlink bearing binding to be arranged, up link binding verification etc.
BSC is the part of base station system, and a kind of switch of high power capacity provides system and wireless function associated, as switching, wireless network resource management and cellular data etc., can carry out the channel management and the channel access control of grouped data.
RNC is the main network element in the third generation wireless network, is the part of access network, is responsible for mobile management, call treatment, link management and transfer mechanism.
As shown in Figure 2, main interface has gn interface and Gi interface in the packet domain.SGSN connects wireless subsystem and core network packet-domain, is connected with GGSN by gn interface; GGSN is connected with outer data network by the Gi interface.
Compare with fixed the Internet, the mobile network has the mechanism and the characteristics of some uniquenesses, and they may influence application and the development of P2P technology in mobile Internet.For example, the radio data channels of GPRS/EDGE/WCDMA adopts time division multiplexing mode up-downgoing balanced configuration, but because the characteristics of mobile Internet application at present, and the part portable terminal has adopted asymmetric data transfer mode, up-downgoing flow difference in for example 2+1 mode or the 4+1 mode, mobile Internet is bigger.Statistics shows that the downlink data flow is about 4.5: 1 with the ratio of upstream data flow in the GPRS network, and this ratio has reached 6.4: 1 after opening EDGE, and the free time relatively of up channel objectively helps P2P and uses.
Along with mobile network's continuous development and evolution, and the continuous enhancing of portable terminal disposal ability, P2P technology and business will extend in the mobile Internet gradually.Fig. 3 is the schematic diagram of the resource lookup of mobile P 2 P network in the prior art.When file of Peer1 search was called the film of " patriot ", detailed process was as follows:
S01, the Peer1 P2P Server in the mobile network sends the query messages for film " patriot ";
S02, P2P Server searches resource, find that Peer2, Peer3, Peer4 node all have target resource, (Resource List) returns to Peer1 with the Resources list, comprising the credit value information of resource place node, wherein, the credit value height shows that the download historical record of this node is good, credit value is low to show that the download historical record of this node is poor, and table 1 is the schematic diagram of prior art P2P resources in network tabulation;
S03, Peer1 selects the higher node of credit value in the Resources list, is Peer2 and Peer4 herein;
S04, Peer1 select Peer4 as kind of a child node at random, and carry out film " patriot's " download from Peer4.
