Method and device for realizing point to point network communicating

The invention discloses a method for realizing point to point network communicating used for realizing the point to point network communicating so as to improve the data transmission efficiency of point to point network. The method comprises the following steps: each node in the point to point network carries out comparison between a self-owned mark with the marks of all the neighboring nodes of the node and judges whether each node meets preset conditions or not; the nodes in all nodes meeting the preset conditions are taken as a first node; and the first node is connected to a second node meeting preset rules. The invention also discloses a device and a system used for realizing the method.
