• a plurality of levels each having at least one information node;
• wherein multiple information nodes of a lower k+1-th level are assigned to an information node of a k-th level configured above the k+1-th level and linked to the information node of the k-th level;
• wherein one information node of the lower k+1-th level is configured to inform the information node of the k-th level regarding (i) which pieces of information the information node of the k+1-th level needs, and (ii) which pieces of information the information node of the k+1-th level is making available.

A method for exchanging information in a communication network having a plurality of levels each including at least one information node, wherein multiple information nodes of a lower k+1-th level are assigned to an information node of a k-th level configured above the k+1-th level and linked to the information node of the k-th level, the method comprising:

• informing the information node of the k-th level, by one information node of the lower k+1-th level, regarding (i) which pieces of information the information node of the k+1-th level needs, and (ii) which pieces of information the information node of the k+1-th level is making available.
