Abstract:

Provided is a management-system for use in a network environment including a first and second IP networks and a transport network which connects the first and second IP networks. The management system includes: a converter for optimizing a path in an IP-domain via a first algorithm and for converting IP-traffic-signals into transport-traffic-signals; and an optimiser which optimizes a topology that overlays the transport network by optimizing channels in the transport-network according to at least one second algorithm. The first algorithm is an IP multi protocol label switching routing optimization algorithm. The second algorithm is an algorithm based on a plurality of constraints and objectives such as a flow conservation constraint, logical link capacity constraint, optical router port constraint, wavelength cost objective, optical router port occupation objective, advertised link number objective, spare capacity objective, wavelength re-use benefit objective and optical service level agreement constraint.

Abstract:

The method applies to a telecommunication network having IP packet-supporting capabilities when said network includes a load distribution processing function which is either centralized or distributed and by means of which a load distribution function is applied to sets of paths between network nodes and/or sets of links (LkLkp) of network trunks (). The load distribution processing function handles different load distribution functions (LDFg, LDFh, LDFj), and each of the different load distribution functions is associated to a different network input unit (G, H, J or P, Peg, P, Pfh) involved in the load distribution for at least a determined set of paths between network nodes or a determined set of trunk links. The invention also relates to a telecommunication network applying the method as summarized above.
