Abstract:
An arrangement for monitoring and managing routing in a communications network comprising:at least one routing domain having at least one routing area that includes a plurality of network nodes that intercommunicate using transmission links; administrating means for administering the at least one routing domain using a link state routing protocol; at least one routing controlling device coupled to at least one network node of a routing area and part of a link state routing process for the routing areas to which the at least one network node belongs, a link state database maintained by the routing controlling device for computing an optimal transmission path between network nodes in the at least one routing domain means means for rejecting non-routing information and traffic presented at the at least one muting controlling device; and means for injecting routing information from the at least one routing controlling device into the link state routing process, for generating, at each of the network nodes that are part of the link state routing process, link state databases that are identical to the link state database maintained by the at least one routing controlling device.
