Complete conveys to those skilled in the art.
The embodiment of the present invention provides a kind of method that release connects, as shown in figure 1, methods described includes：
When the 101st, there is split connection between two calculate nodes, the first calculate node receives the second calculate node and sends
The second ruling weights.
The embodiment of the present invention is applied in peer-to-peer network (Peer to Peer, P2P) environment, there are multiple calculate nodes,
Those calculate nodes concrete identical function, dereliction takes second place point, and that is, all calculate nodes in P2P network environment are all in equity
Status, can directly Sharing computer resource and service between any two calculate node.
In P2P network environment, the calculate node communication set up communication path, and node between spontaneous with calculate node
There is randomness, below with any two calculate node in P2P network environment：First calculate node with the second calculate node is
Example illustrates.First calculate node, as connecting initiator, sends to the second calculate node and sets up connection request, set up first
Path between calculate node and the second calculate node；Now, the second calculate node, as connecting initiator, calculates section to first
Point sends sets up the request connecting, and sets up the path between the second calculate node and the first calculate node.Now, first calculate section
There are two communication paths after point and the second calculate node, exist split between the first calculate node and the second calculate node
Connect, and in actual applications, communication between two nodes, only need a communication path, if two identicals calculating
There are two communication paths between node, then can cause the waste of system resource.
Can be drawn by above-mentioned, the condition that two calculate nodes have split connection is：Between two calculate nodes never
Communication, and two calculate nodes send, to other side, the request setting up network service connection simultaneously, and this kind of connected mode occurs
Two calculate nodes set up communication channel to other side simultaneously, there is split connection between two calculate nodes.
It should be noted that the first calculate node here with the second calculation stages merely to convenience in description, its
Do not imply that in a P2P network environment only have two nodes, but can the multiple calculate node of the person of inclusion, and each calculate section
Point is respectively provided with identical function.
In the prior art it is assumed that in peer-to-peer network (Peer to Peer, a P2P) environment, comprising N=30 meter
Operator node, in theory, sets up N (N-1)/2=435 connection and can achieve institute in P2P network environment between two calculate nodes
Have the communication between node, but, in actual applications, the worst in the case of may produce N (N-1)=870 connection, real

The disposable successful probability of ruling is bigger, number range setting less, the successful probability of disposable ruling is less, specific this
Inventive embodiments are not construed as limiting to the number range of ruling weights.
As another kind of implementation of the embodiment of the present invention, set up split in the first calculate node and the second calculate node
After network, when the first calculate node and the second calculate node send ruling weights first, can directly be accounted for using connection initiator
Local port number, this local port number be set up transmission control protocol (Transmission Control Protocol,
When TCP) connecting, connect initiator and can take local a port at random, using this local port number as ruling weights, Neng Goujia
Fast ruling speed.This kind of explanation mode is not intended to limit the local port number that ruling weights are only capable of taking for connection initiator.
In actual applications, after the first calculate node and the second calculate node set up split connection, both of which will be to other side
Send the ruling weights of its own, so that both ruling weights are compared, that is, the first calculate node receives the second calculating
The second ruling weights that node sends, the second calculate node receives the first ruling weights that the first calculate node sends.Hereinafter, will
Taking the first calculate node as a example the process of ruling is illustrated.
102nd, described second ruling weights and the first ruling weights of itself are compared by the first calculate node.
Described first ruling weights and described second ruling weights are respectively described first calculate node and described second meter
The random numerical value generating of operator node.
Because ruling weights are substantially a numerical value, its have size point, in the first calculate node by the first umpirage
When value and the second ruling weights are compared, compare the numerical values recited of the first ruling weights and the second ruling weights.Example
Property it is assumed that the first ruling weights be 36, the second ruling weights be 50, then the first calculate node determine the first ruling weights with
Second ruling weights are different, and the first ruling weights are less than the second ruling weights, these are only exemplary citing, and the present invention is real
Apply example the specific size of ruling weights is not construed as limiting.
If 103 described second ruling weights are different from described first ruling weights, the first calculate node disconnects split company
A connection in connecing.
When the second ruling weights are different from the first ruling weights, including：Second ruling weights be more than the first ruling weights,
Second ruling weights are less than two kinds of situations of the first ruling weights, when the arbitrary comparison result in above-mentioned two situations determines, first
Calculate node actively disconnects split wherein one connection in connecting, or, the first calculate node sends to the second calculate node
Configured information, is disconnected wherein one connection in split connection by the second calculate node.
, between two calculate nodes of determination, there is split connection in the method that release provided in an embodiment of the present invention connects
When, the first calculate node receives the second ruling weights that the second calculate node sends, by the second ruling weights and itself first
Ruling weights are compared however, it is determined that the second ruling weights are different from the first ruling weights, then disconnect in split connection
Connect, compared with prior art, in the case of there is split connection in two calculate nodes of determination in the embodiment of the present invention, Ke Yi
Voluntarily consult between this two calculate nodes, disconnect any bar in split connection and connect, realize passing through between two calculate nodes
Article one, connection is communicated, and the process that this is voluntarily consulted is simple, efficient and easy to be realized such that it is able to reduce split connection to system
Resource and the consumption of Internet resources.
