It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
The embodiment of the present invention provides a kind of method of release connection, as shown in Figure 1, which comprises
101, when, there are when split connection, the first calculate node receives the second calculate node and sends between two calculate nodes
The second ruling weight.
The embodiment of the present invention is applied in peer-to-peer network (Peer to Peer, P2P) environment, there are multiple calculate nodes,
The specific identical function of those calculate nodes, dereliction take second place point, i.e., 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, calculate node and the spontaneous communication established between communication path and node of calculate node
With randomness, below with any two calculate node in P2P network environment: the first calculate node is with the second calculate node
Example is illustrated.First calculate node establishes connection request as connection initiator, to the transmission of the second calculate node, establishes first
Access between calculate node and the second calculate node；At this point, the second calculate node calculates section as connection initiator, to first
Point sends the request for establishing connection, establishes the access between the second calculate node and the first calculate node.At this point, first calculates section
There are two communication paths later with the second calculate node for point, i.e. there are split between the first calculate node and the second calculate node
Connection, and in practical applications, the communication between two nodes only needs a communication path, if two identical calculating
There are two communication paths between node, it will cause the wastes of system resource.
It can be concluded that, there are the conditions of split connection for two calculate nodes are as follows: between two calculate nodes never by above-mentioned
Communication, and two calculate nodes send the request establishing network communication and connecting to other side simultaneously, and this kind of connection type will appear
Two calculate nodes establish communication channel to other side simultaneously, i.e. there are split connections between two calculate nodes.
It should be noted that the first calculate node here and the second calculation stages are merely to convenience in description,
It does not imply that in a P2P network environment only there are two node, but the multiple calculate nodes of the person of may include, and each calculatings section
Point all has identical function.
In the prior art, it is assumed that in peer-to-peer network (Peer to Peer, a P2P) environment, include N=30 meter
Operator node, theoretically, N (N-1)/2=435 connection is established between two calculate nodes can be realized institute in P2P network environment
There is the communication between node, still, in practical applications, N (N-1)=870 connection may be generated in the worst case, it is real
The connection number that border is established has more one times than the connection number theoretically established, and nothing is established between calculate node and calculate node
Connection causes the occupancy of calculate node upper port, in addition, by a large amount of system resource of fearless waste and Internet resources.
To solve the above-mentioned problems, in the embodiment of the present invention, when determining between two calculate nodes there are when split connection,
First calculate node receives the second ruling weight that the second calculate node is sent, and the second calculate node receives the first calculate node hair
The the first ruling weight sent, wherein ruling weight is the numerical value that calculate node generates at random, and the numerical value has a numerical value model
It encloses, for example, numberical range is 0-65535 etc., specifically, numberical range is bigger when setting the numberical range of ruling weight,
The successful probability of disposable ruling is bigger, and numberical range is arranged smaller, and the disposable successful probability of ruling is smaller, specifically originally
Inventive embodiments are not construed as limiting the numberical range of ruling weight.
As another implementation of the embodiment of the present invention, establish in the first calculate node with the second calculate node split
After network, when the first calculate node and the second calculate node send ruling weight for the first time, can directly it be accounted for using connection initiator
Local port number, the local port number be establish transmission control protocol (Transmission Control Protocol,
When TCP) connecting, connection initiator can occupy local a port at random, using the local port number as ruling weight, Neng Goujia
Fast ruling speed.This kind illustrates that mode is not intended to restriction ruling weight and is only capable of the local port number occupied for connection initiator.
It in practical applications, both will be to other side after the first calculate node and the second calculate node establish split connection
The ruling weight of its own is sent, so that the ruling weight of the two to be compared, i.e. the first calculate node receives second and calculates
The second ruling weight that node is sent, the second calculate node receive the first ruling weight that the first calculate node is sent.Hereinafter, will
The process of ruling is illustrated by taking the first calculate node as an example.
102, the second ruling weight is compared the first calculate node with the first ruling weight of itself.
The first ruling weight and the second ruling weight are respectively first calculate node and second meter
The numerical value that operator node generates at random.
Since ruling weight is substantially a numerical value, point with size, in the first calculate node by the first umpirage
When value is compared with the second ruling weight, the numerical values recited of the first ruling weight and the second ruling weight is compared.Example
Property, it is assumed that the first ruling weight be 36, the second ruling weight be 50, then the first calculate node determine the first ruling weight with
Second ruling weight is different, and the first ruling weight, less than the second ruling weight, the above is only illustrative citing, the present invention is real
Example is applied to be not construed as limiting the specific size of ruling weight.
If 103, the second ruling weight is different from the first ruling weight, the first calculate node disconnects split company
A connection in connecing.
When the second ruling weight and the first ruling weight difference, comprising: the second ruling weight be greater than the first ruling weight,
Second ruling weight is less than two kinds of situations of the first ruling weight, when any comparison result in above-mentioned two situations determines, first
Calculate node actively disconnects the wherein connection in split connection, alternatively, the first calculate node is sent to the second calculate node
It indicates information, the wherein connection in split connection is disconnected by the second calculate node.
The method of release connection provided in an embodiment of the present invention, when determining that there are split connections between two calculate nodes
When, the first calculate node receives the second ruling weight that the second calculate node is sent, by the second ruling weight and itself first
Ruling weight is compared, however, it is determined that the second ruling weight is different from the first ruling weight, then disconnects one in split connection
Connection, compared with prior art, the embodiment of the present invention determine two calculate nodes there are in the case where split connection, Ke Yi
Voluntarily negotiate between two calculate nodes, disconnects any bar in split connection and connect, realize and pass through between two calculate nodes
One connection is communicated, and the process voluntarily negotiated is simple, efficient and easy realization, so as to reduce split connection to system
The consumption of resource and Internet resources.
