Abstract: A network management system for a multi-layer network having multiple architectural or technological domains includes an inter-domain configuration manager arranged between a set of one or more network service management applications and a set of network element domain managers, each of the domain managers being associated with a particular domain of the multi-layer network. The configuration manager implements network service design and provisioning functions across the domains of the network in conjunction with stored connectivity information characterizing the multi-layer network. The network management system further includes an inter-domain fault manager and an inter-domain capacity manager, which provide respective fault management and transport capacity management functions across the domains of the multi-layer network.

Abstract: This invention relates to a method and apparatus for network voice and data traffic monitoring and congestion management for diverse and converged networks. More particularly, the invention is directed to an interdomain congestion management architecture having the ability to analyze and correlate congestion problems across multiple domains, provide integrated network maps, tabular displays and/or reports and allow network managers, in appropriate circumstances, to navigate to a domain to implement corrective actions.
