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