Abstract
A method of calculating a path in a first layer of a multi-layer network comprises receiving information corresponding to one or more parameter from a second layer of the multi-layer network. The one or more parameter relates to a summarization of links between edge nodes of the second layer connected with the first layer. The method further comprises calculating a path in the first layer using the received information from the second layer.
Claims18
A method of calculating a path in a first layer of a multi-layer network, comprising:
- receiving information corresponding to one or more parameter from a second layer of the multi-layer network,
- wherein the one or more parameter relates to a summarization of links between edge nodes of the second layer connected with the first layer;
- and
- calculating a path in the first layer using the received information from the second layer.
An apparatus configured to determine a path in a first layer of a multi-layer network, the apparatus comprising:
- a receiving unit configured to receive information corresponding to one or more parameter from a second layer of the multi-layer network,
- wherein the one or more parameter relates to a summarization of links between edge nodes of the second layer connected with the first layer;
- and
- a path calculation unit configured to calculate a path in the first layer using the received information of the second layer.
A method of a second layer of a multi-layer network, comprising:
- obtaining information corresponding to one or more parameter of the second layer;
- summarizing the information on links between edge nodes of the second layer connected with the first layer;
- and
- transmitting the summarized information corresponding to the one or more parameter to a first layer of the multi-layer network, wherein the information is useable for calculating a path in the first layer.
An apparatus configured to provide information of a second layer of a multi-layer network, the apparatus comprising:
- a receiving unit configured to obtain information corresponding to one or more parameter of the second layer,
- a calculation unit configured to summarize the information on links between edge nodes of the second layer connected with the first layer;
- a transmission unit configured to transmit the summarized information corresponding to the one or more parameter to a first layer of the multi-layer network, wherein the information is useable for calculating a path in the first layer.
(canceled)
A nontransitory computer readable storage medium comprising program instructions that, when run on a computer, cause the computer to perform a method of calculating a path in a first layer of a multi-layer network, the method comprising:
- receiving information corresponding to one or more parameter from a second layer of the multi-layer network,
- wherein the one or more parameter relates to a summarization of links between edge nodes of the second layer connected with the first layer;
- and
- calculating a path in the first layer using the received information from the second layer.
