Patent ID: 7395318

Claim:
A method for communication between technical devices being nodes in networks, wherein a common group label is assigned to nodes being a member of a group of nodes, and wherein the nodes of said group can cooperate with all other members of the same group of nodes, including the steps of: defining for the group of nodes one or more classes of group labels; classifying one or more group labels into a first class; detecting in a first node belonging to said group of nodes access from a second node; detecting the group label of the second node; permitting said access if the group label of the second node is equal to the group label of the first node; otherwise determining if the group label of the second node is classified into the first class and; permitting said access if the group label of the second node is classified into the first class, otherwise rejecting said access the first class of group labels has one or more subclasses, and wherein different types of accesses are defined depending on the subclass, and wherein also the subclass of the group label of the second node is determined.
