ROUTING METHOD FOR OPTIMISING LINK CAPACITY AND INCREASING AVAILABILITY

摘要

The invention relates to a routing method for optimising a link capacity and increasing an availability in nodes (x, Y1, Y2, Z) and links (L1, L2) of a packet-based communications network, wherein a routed data transmission (DV) is associated with at least two priority steps (PKn, PKe). A high-priority step data transmission (PKe) is subsequently routed. A low-priority step data transmission (PKn) is afterwards routed. For routing the data transmission (DV) routing methods known per se, whose use is adapted to the requirements of each data transmission (DV), are used. The advantages attained by said invention lie mainly in that the optimal link capacity, a high reliability and a quick error reaction for the corresponding data transmission (DV) are simultaneously obtained. Said invention makes it possible to assign each data transmission (DV) to a high priority step (PKe) such as, for example, a real-time requirement data transmission (DV) is routed in priority by the communications network and the low-priority step (PKn) data transmission (DV) is routed on links (L1, L2).
