Abstract
Official abstract text for this publication.
Embodiments of the present application provide a label switching path calculation method and a label switching path calculation device. In the method, by performing hierarchical level and domain value planning on a node in a network in advance, when an LSP is calculated, hierarchical domain information about each node is acquired, and the LSP is calculated using the acquired hierarchical domain information about each node. Since the hierarchical domain information about each node designates a network position where the node is located, it can be avoided that an LSP obtained by calculation reroutes an access layer according to the hierarchical domain information about each node and a satisfaction criterion for the LSP during the LSP calculation process. In addition, the technical solution provided in the embodiments of the present application needs no manual intervention in the whole LSP calculation process, realizing the automatic calculation of an LSP.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for calculating a label switching path LSP), comprising: acquiring layer domain information of one or more nodes in an autonomous system where a source node in a network is located, wherein, for each of the one or more nodes, the layer domain information of the node comprises information of a layer rank of the node and information of a domain value of the node; wherein in the network, each node has a layer rank and at least one domain value; wherein…
