A method for use in a broadband network includes displaying the cumulative amounts in a hierarchy of network issues, the hierarchy including a summary category including summary values indicating total cumulative amounts of time that the network elements in the at least a desired portion of the network were considered at corresponding qualities of performance, the hierarchy further including a plurality of sub-categories contributing to the summary category, and the sub-categories each further comprising at least one sub-sub-category contributing to the sub-categories.

Network performance monitoring

The apparatus (,) and method for spectrum management in a multipoint communication system controls upstream channel usage for secondary stations (,) transmitting information to a primary station (,) and downstream channel usage for secondary stations (,) receiving information from a primary station (,). The preferred apparatus (,) embodiment includes a processor arrangement (,) having a master controller (,) and a plurality of processors (,), with the processor arrangement connected to a channel interface (,). The apparatus (,) and method controls channel load balancing, channel congestion, and channel assignment in a multipoint communication system, and controls upstream channels independently from downstream channels. Factors and parameters utilized in such channel control and allocation include error parameters, channel noise parameters, transmit and receive loading factors, and congestion parameters.

Apparatus and method for spectrum management in a multipoint communication system

An apparatus (110, 101), method, system (100) and system method provide for distributed internetwork routing of information in a communication system (100). The communication system (100) is characterized by a topology having a primary node connected to a first network, such as the Internet, and connected via an intermediate network to a mulitplicity of secondary nodes, which are further connected via a secondary network to a plurality of terminals, such as personal computers. The apparatus (110, 101), method, system and system method provide for routing of information between the primary node and the terminals independently of and transparently to any internetwork address of a secondary node. The apparatus (110, 101), method, system and system method conserve internetwork addresses by utilizing internetwork addresses only for a primary node and for terminals.
