Abstract
The invention relates to a system, device, method and computer program product for controlling the flows of a plurality of Data Units (DUs) over logical links, the system comprising at least two first-type Link Control (LC) entities (40-1a . . . 40-8a), wherein each first-type LC entity transforms a first-type DU into a second-type DU and vice versa, and provides a first interface (43-1 . . . 43-8a) for the first-type DUs and a second interface for the second type DUs, and a second-type LC entity (5a) with interfaces (50-1a . . . 50-8a) for the second-type DUs, wherein the second interface of each of the first-type LC entities (40-1a . . . 40-8a) is directly connected to one respective interface (50-1a . . . 50-8a) of the second-type LC entity (5a), and wherein the second-type LC entity (5a) comprises a flow control device (52a) for separately controlling the respective flows of the second-type DUs, which are transferred over its respective interfaces (50-1a . . . 50-8a).
