METHOD AND SYSTEM FOR DATA COMMUNICATION IN HIERARCHICALLY STRUCTURED NETWORK

摘要

A method for data communication in a hierarchically structured network comprising at least two lower level entities on a lower level, at least one higher level entity on a higher level, wherein each higher level entity provides low link connections to each of the lower level entities and high link connections to at least one further high level entity wherein a lower level entity the higher level entity connected to the said low level entity and the high level entity connected to said higher level entity defines a connection branch, comprising the steps a) Determining communication capabilities of the low link and high link connections in each connection branch, b) Providing communication capability information according to the determined communication capabilities to the lower level entities, c) Determining the connections in each connection bran ch having the lower one of the data communication capability, and d) Adapting the data communication capabilities of the connections in each connection branch according to the determined lower data communication capability. The invention relates also to a corresponding system.
