Abstract
A method for delivering published messages to subscribers comprises: —storing a set of subscriptions (F1_top1, F2_top3, F3_top4) in a routing table (RTO) of a first broker (BRO), —sending a set of messages (e1, e2, e3) from the first broker (BRO) to a second broker (BR1) according to at least one subscription (F1_top1) stored in the routing table (RTO)1 —receiving a subsequent message (ek), —determining a search term (topi) based on a data element of the subsequent message (ek), —comparing the search term (topi) with a set of data elements stored in a relation repository (CRR), and —controlling sending of the subsequent message (ek) to the second broker (BR1) according to a result of said comparison, wherein the set of data elements stored in the relation repository (CRR) comprises data elements of the messages (e1, e2, e3) previously sent to the second broker (BR1), and wherein said set of subscriptions (F1_top1, F2_top3, F3_top4) contains at least one subscription (F3_top4), which specifies a topic (top4), which is not contained in the set of data elements stored in the relation repository (CRR).
