Wherein, N is the positive integer more than 2.
As shown in Figure 1, being illustrated so that N is 5 as an example in the figure.If there is 5 nodes, then one of node is
Host node is expressed as master, and in addition 4 are divided from node than being slave1, slave2, slave3 and slave4.In the system
In, when position relationship of each node, is arbitrary, i.e. the two neighboring node of slave1 can be slave2 and slave3, also may be used
Think slave2 and slave4.But the position regardless of node, the final connection structure of all nodes is to be sequentially connected
At a ring-type.In Fig. 1, if headed by master, be followed successively by slave1, slave2, slave3 and
Slave4, slave4 are exactly tail, and then slave4 is connect with master again, thus form the ring-type of a closure.At this
After ring-type is formed, each have from node and only two adjacent nodes, but host node also connects with all from node
It connects.It is exactly master in figure other than its adjacent two nodes slave1 and slave4, also connects with slave2 and slave3
It connects.
