Abstract: Known network management systems for managing traffic signals in a network store node/link parameter signals and traffic parameter signals and calculate solutions defining intermediate nodes/links situated between sources and destinations for transporting said traffic signals from said sources to said destinations via said intermediate nodes/links and calculate route information per solution. By storing node/link parameter signals and traffic parameter signals for several situations (like several predictions in the future) and calculating solutions for each situation and then selecting a solution per situation, the network management system will manage the network more advantageously, especially when solutions are compared with each other, and when a solution is selected per situation in dependence of comparison results (comprising similarities/differences between solutions of different situations).

Abstract: The present invention is related to a method to control and to change dynamically a MAC address in an aggregation network containing at least a server computer device and a client device, comprising the steps of: Sending from said client device to a server computer device a message (1,11) containing the MAC address of said client computer device, Retrieving said MAC address from said message at said server computer device (2,12), Checking if said MAC address is already in use (by a user) in said network or if said server computer device wants to change all MAC addresses in said network, If so, sending from said server computer device to said client device a message (3,13) containing a new MAC address for said client, Overwriting said MAC address with said new MAC address in said client computer device (4,14).

Abstract: The present invention relates to a method for establishing a path, having a certain QOS-class, between a modem and an edge node over a communications network. The communications network comprises an Access Multiplexer and an Ethernet aggregation network, where the Access Multiplexer couples the modem to the Ethernet aggregation network. The modem is coupled to the Access Multiplexer over at least one ATM connection. The modem forwards an ARP request, that is received from a host terminal, for an address of the edge Node over an ATM having a certain QOS-class. The Access Multiplexer intercepts the ARP request that is forwarded by the modem and assigns a chosen address for the edge node based on information on the edge node that is contained in the ARP request. Subsequently, the Access Multiplexer includes this chosen address in an ARP reply.

The Routing Gateway is coupled to each device of said plurality of devices. The Remote management method comprises the step of an Auto-Configuration Server managing either one of a dedicated device of said plurality of devices and the Routing Gateway or both at request. A further Auto-Configuration Server requesting the Auto-Configuration Server to access and configure the Routing Gateway for providing the further Auto-Configuration Server access to the Routing Gateway and subsequently the Auto-Configuration Server configuring the Routing Gateway to provide the further Auto-Configuration Server access to the Routing Gateway.

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: Network management systems for managing networks comprising nodes adapt their information parameters, via a one-step-replacement of old information parameters by new information parameters. These network management systems do not keep any transition-overview and must accept the new situation. By introducing a more-than-one-step-replacement via intermediate states, a transition-overview is kept, with said intermediate states allowing so-called make-before-break transitions. Preferably the adaptions are made in an optimised way, by defining constants and variables, and processing at least one objective and constraints, for example all being a function of routing parameters and/or of capacity parameters and/or of intermediate states. Networks comprising such network management systems as well as methods for managing such networks and comprising a step of adapting information parameters via intermediate states are more efficient and reliable.

Abstract: Network-systems comprising IP-networks with nodes (label switched routers) and edge-nodes (those routers coupled to a transport-network) and a transport-network (optical network) comprising channel-switches (optical cross connects) and a management-system for managing networks in an overlay environment (where the topology of the transport.network is not known to the management-system) deal with traffic non-optimally. By providing said management-system with a converter for converting IP-traffic-signals into transport-traffic-signals thereby assuming that both IP-networks are coupled via a star-network with said transport-network corresponding to a star of said star-network, and with an optimiser for in response to said converting optimising a use of channels in said transport-network according to an algorithm, network-systems can handle traffic more optimally. Said algorithm is defined by at least several constraints and several objectives.
