Description
Technical field
(Peer-to-Peer, P2P) network more particularly, relate to a kind of method and system of the P2P of raising network stabilization to the present invention relates to equity.
Background technology
The P2P network is a kind of distributed network, its network node be service providers also be the beneficiary of service, typical as P2P download, certain node is in other node file in download, its file of sharing also provides download for other node.
The P2P network has 4 types topological structure: centralization topology, full distributed destructuring topology, all distributed structureization topology and half distribution topology.Wherein, half distribution topology selects the higher node of performance (performances of aspects such as processing, storage, bandwidth) as super node, under each super node, hang the ordinary node of some, and the information of storing other nodes in the system, it is responsible for handling or transmitting the request of above-mentioned ordinary node.Half distributed topology of P2P network is a hierarchy type structure, constitutes one between the super node and transmits layer at a high speed, then constitutes some levels between super node and the common node be responsible for.
At the P2P network, especially in the semi-distributed P 2 P network, the landfall process of an ordinary node may further comprise the steps:
1, ordinary node at first sends the request of landing to server, and request adds this P2P network;
2, whether this ordinary node of server authentication is legal, legal commentaries on classics 3, illegal commentaries on classics 4;
3, ordinary node returns the information of some super nodes by the checking of server, changes 5;
4, ordinary node returns and lands failure not by server authentication;
5, ordinary node sends the request of landing to super node again;
6, super node receive ordinary node land request after, earlier whether this ordinary node of checking legal, and judges and oneself (for example can accept this ordinary node, the ordinary node that this super node is hung down is too much, then it can not accept this ordinary node), satisfying condition changes 7, otherwise changes 8;
7, ordinary node is received the grant message that lands that super node returns, and then completes successfully and lands;
8, super node returns and lands refuse information, then lands failure.
As mentioned above, in existing P 2P network (being typically the P2P network of half distributed topology), an ordinary node lands the process that super node must be finished " server lands checking " and " super node lands checking " two information interactions and judgement.
The advantage of the P2P network of this half distributed topology is that performance and extensibility are better, be easy to management, but that its defective is the dependence of super node is strong, if certain super node rolls off the production line, with making its whole ordinary nodes of being hung down be forced to roll off the production line, need land again.If roll off the production line on super node is frequent, will cause whole network system shake violent, also pose a big pressure simultaneously to server.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Among the present invention behind ordinary node certain super node in landing the P2P network, seek other super nodes in this network as the backup of this super node, when rolling off the production line, this super node notify this backup super node as formal super node and switching rapidly, backup once more simultaneously.Such P2P network system can guarantee that the ordinary node in the network is online all the time, and for ordinary node of the prior art needed heavily to land repeatedly, the present invention only need keep backup to get final product, and has greatly strengthened stability of network.
Fig. 1 shows the structure of P2P network system among the present invention, comprises server 100, real-time super node 200, ordinary node 300 and backup super node 400.
Above-mentioned server 100, in real time super node 200, ordinary node 300 are consistent with existing P 2P network system, and backup super node 400 is identical with the function and the character of real-time super node 200 in fact, all can be super node in general sense.In the present invention, each ordinary node 300 lands after certain super node, and this super node promptly becomes the real-time super node of this ordinary node 300, promptly aforesaid real-time super node 200; And simultaneously, other super nodes that this ordinary node 300 is also sought in the P2P network back up, and also are above-mentioned backup super node 400.Therefore, super node 200 has only one all the time in real time, and backup super node 400 then can be one or more.Differentiate that a super node is that the real-time super node or the method for backup super node are by the contained status identifier of super node, in the P2P network system in the present invention, each super node all comprises self a status identifier P: if P=true shows that then this super node is foregoing real-time super node 200; If P=false shows that then this super node is foregoing backup super node 400.Certainly, the assignment of above-mentioned status identifier P also can be taked other modes, and the present invention is not limited to certain specific assignment mode.
When certain real-time super node 200 can operate as normal, hang a plurality of ordinary nodes 300 it under, this moment, super node 200 was responsible for the request of ordinary node 300 is handled or transmitted in real time, backed up super node 400 and did not work; When real-time super node 200 cisco unity malfunctions (as rolling off the production line), 400 signaling packets that contain the status identifier configuration information that send according to ordinary node 300 of backup super node, revise the assignment of himself status identifier (if according to foregoing assignment mode according to this status identifier configuration information, that is: " P=false " changed to " P=true "), then this backup super node 400 becomes the real-time super node of this moment, and fulfil all responsibilities and function as super node, the request of ordinary node 300 is handled or transmitted.
Because the existence of backup super node 400 is arranged in the P2P network system of the present invention, guaranteed that its a large amount of ordinary nodes of being hung down can not be forced to roll off the production line when real-time super node 200 rolls off the production line, get final product operate as normal and only need switch to a backup super node 400, this is the basic reason that P2P network system of the present invention can keep high stability.
Fig. 2 shows the method flow that the present invention improves the P2P network stabilization, may further comprise the steps:
Among the step S201, ordinary node 300 sends the request of landing to server 100, i.e. request adds this P2P network, and by then successful game server 100 after the checking of server 100, server 100 returns the information of some super nodes to ordinary node 300 simultaneously.
Among the step S202, ordinary node 300 sends to certain super node and lands request, lands success after the checking by this super node, and then this super node becomes the real-time super node 200 of this ordinary node 300.In this step, this super node receive ordinary node 300 land request after, earlier whether this ordinary node 300 of checking legal, and judges and oneself can accept this ordinary node, for example, if the ordinary node of extension is not through accepting this ordinary node at most under this super node.Have only when satisfying above condition, this super node just returns and lands grant message and allow it to land for ordinary node 300, thereby this super node becomes the real-time super node of this ordinary node 300.The process of ordinary node game server and super node is identical in the implementation procedure of above step S201 and S202 and the prior art.
Among the step S203, ordinary node 300 is sought other super nodes and is sent backup request in the P2P network system, by after the backup permission then with the backup super node 400 of this super node as real-time super node 200.In this step, after these other super nodes are received the backup request of ordinary node 300, at first to judge and oneself can accept the request of this ordinary node 300, for example, if the ordinary node that this super node is hung down is not through receiving the request of this ordinary node 300 at most.Have only when this super node and determine to accept this ordinary node 300, just return the backup grant message and allow its backup for this ordinary node 300, thereby this super node becomes the backup super node 400 of this ordinary node 300 through judging.About backup, also promptly this ordinary node 300 is kept heartbeat with this backup super node 400: this ordinary node 300 regularly sends a packet to this backup super node 400, informs that its state is still for online.
Among the step S204, when the real-time super node 200 of ordinary node 300 rolls off the production line, these ordinary node 300 notice backup super nodes 400 become the real-time super node of this moment and realize rapidly switching, this ordinary node 300 operation among the execution in step S203 is once more simultaneously sought new super node as backup.In this step, the detailed content that ordinary node 300 switches to backup super node 400 is: when real-time super node 200 rolls off the production line, ordinary node 300 sends signaling packet immediately to backup super node 400, contain the status identifier configuration information in this signaling packet, ask this backup super node 400 to become real-time super node; When the backup super node receives above-mentioned signaling packet, then the assignment of revising himself status identifier according to the status identifier configuration information (for example, " P=false " changed to " P=true "), then this backup super node 400 becomes the real-time super node of this moment.In addition, the present invention realizes successfully that in this step switching the back continues execution in step S203, seeking new super node backs up, purpose is the stability that can always keep height for the P2P network system that guarantees its place, and arbitrary at any time real-time super node 200 can both guarantee when rolling off the production line that its ordinary node of being hung down can normally move.
Need to prove that the present invention mainly is suitable for but is not limited to the P2P network of half distributed topology, so long as include the P2P network of super node, all can use technical scheme of the present invention to improve this P2P stability of network.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
