Determining and provisioning paths in a network

Abstract From the Canadian patent

A network provisionning system for establishing a path between two networks is disclosed wherein a common , network device between those networks is modeled as a link between a first network element in one network and a second network element in a second network. A network routing graph is created by an inventory subsystem in a routing manager by inventorying the physical network elements and links in the network. The inventory subsystem then models those elements/links as a plurality of nodes and links between the nodes. At least one common network device such , as a digital cross connect connecting the two networks, is modeled as a link instead of a node. A routing engine then …
