Disclosed is a service provisioning tool and method for determining favorable implementations of a service in a grid-less optical network, wherein said service provisioning tool is configured to assign total cost values to a given implementations, select the implementation or a group of implementations having the lowest cost, wherein said total cost values are based on &#x2014;cost values regarding selectable data rates on individual links, &#x2014;cost values regarding necessity to install additional equipment, &#x2014;cost values regarding selectable signal frequency bands. One or more of said cost values are dynamically changing as a function of one or more of the degree of utilization, the lifetime of the service, the time available for establishing the service, a modulation format and a signal power. The cost value per band width varies, depending on one or more of the size of the selected frequency band, and to what extent the selected frequency band fills gaps between occupied spectral ranges or creates gaps remaining between occupied spectral ranges.

Method and tool for service provisioning with improved spectral efficiency in grid-less optical networks

A method and a device for service provisioning in a communication network are provided, wherein a resource is utilized in the communication network, which resource is not yet available for productive use by the network. Also, an according communication system comprising at least one such device is suggested.

Method and device for service provisioning in a communication network

Services are transmittable via a transport network by using container(s), wherein each container is adapted to transmit data with a specific bandwidth and is multiplexable, according to a dynamic multiplexing structure, to at least another container adapted to transmit data with a higher bandwidth. The network management system selects a container being adapted to transmit data with a first bandwidth out of the number of containers, determines all containers of the number of containers being adapted to transmit data with a bandwidth lower than the first bandwidth, and defines all possible termination points for each determined container. All possible termination points are defined before a service to be transmitted is selected by a user. A number of the possible termination points for each determined container is selected based on a selection scheme in order to provide the selected number of the possible termination points to the user.

Network management system

Method and device for processing a communication network A method and a device for processing a communication network are provided, wherein (a) a first performance parameter of the communication network is determined; (b) a third performance parameter is determined based on the first performance parameter and a second performance parameter, which second performance parameter was previously determined, wherein the second performance parameter comprises a forecast of an expected network performance over time until the end of the scheduled lifetime of the communication network; and (c) the communication network is processed based on the third performance parameter. Furthermore, an according computer program product is suggested.
