In the present embodiment, when the retransmitting message number of times for having communication data reaches preset times, determine institute
The corresponding node of communication data is stated, according to first embodiment, the node carries out multiple retransmitting message,
The communication speed for being likely to be message sequence is very fast, or has just received the message sequence in node
During message, token information has arrived at the node, and now the node will can only be received in message sequence
A part of message, cause message to be missed, therefore, the present embodiment preferably by token gap periods parameter expand
Greatly, that is to say, that increase the time that the node receives the token information of the cluster, to reduce the section
The retransmitting message number of times of point, will in the isomeric group time of token information transmission increase, Yuan Xian
If the 6 seconds time of token information is transmitted in isomeric group, and in the isomeric group, there are 3 nodes,
So each node receives the as 2 seconds time of token information, now by token information in the isomery
The time transmitted in cluster increases to 9 seconds, then each node receives time of token information and is 3 seconds,
The node is so conducive to receive complete message sequence, so as to reduce the retransmitting message of the node
Number of times.Further, after the parameter for having adjusted the corresponding node of the communication data, can be by the section
The retransmitting message number of times of point resets, and in new round isomeric group communication process, continues statistics described different

Oneself attribute information my_proc_set, is synchronously comprising all node identification informations by attribute information
New attribute information, attribute information P1P2P3 that will be described node P1, P2, P3 original are updated to new category
Property information P1P2P3P4, and described node P1, P2, P3 also can broadcast its JoinMsg to cluster and disappear
Breath, now the node P4 also can receive node P1, P2, P3 broadcast JoinMsg message when,
Its attribute information is updated to into new attribute information P1P2P3P4, it is to be understood that carry out in each node
During broadcast JoinMsg message, as long as node receives the JoinMsg message of other node broadcasts, will be by
The attribute information of JoinMsg message is compared with the attribute information of itself, if comparing in message
My_pro_set is identical with the my_proc_set contents of oneself, that is, the attribute information for receiving and each node
When corresponding attribute information is consistent, then the sender_id in JoinMsg message is arranged to consensus,
Namely by the attribute information of each node corresponding transmission address information setting sync id, and
Show in consensus lists, finally enter isomeric group communication state.
