ABSTRACT:
The present invention relates to a telecommunications node (1a) that is able to handle IP-traffic and to terminate telecommunications traffic, which node includes means for simple and effective load distribution between resources (40-43) in the node. The inventive telecommunications node (1a) includes board internal IP-subnets (45, 46) with associated subnet interfaces (45a, 46a) having interface addresses and a distributed forwarding engine structure where every device board (10, 11a, 12a) associated with the handling of IP-traffic is provided with a forwarding engine (20-22). Each board internal IP-subnet (45, 46) is associated with at least one predetermined node resource (40-43) for processing telecommunications traffic, thereby enabling a resource manager (49) to perform load distribution by ordering a destination address for a selected stream of IP-traffic, which is to terminate in the node, to be based on the interface address associated with a selected board internal IP-subnet (45, 46).
