Abstract: 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.

Abstract: A computer program product includes computer-executable instructions for causing a computer to obtain performance data related to performance of a broadband network, and provide a hierarchical display of network performance, the hierarchical display including a first level with first data indicative of network operation and a second level with second data indicative of a plurality of issues comprising the first level of network performance, where the second level includes multiple issues that contain a third level with third data indicative of network issues comprising at least some of the secondary level issues.

Abstract: An apparatus and method for generating connected graphs for display on a computer monitor. A data structure and virtual map are defined which provide a linked list of objects appearing at any location in the connected graph, the virtual map being larger than the dimensions of the display monitor if the connected graph demands larger dimensions. Commands carried out with respect to any object on the monitor are correlated with the cell maps in the virtual map, which point to the linked lists of objects, the lists in turn pointing to objects stored in an object records database. This provides rapid access to all objects at any given location on the display or in the connected graph. When a user gives a command to create a connection between two objects in the graph, the method generates the shortest connection possible, in terms of both pixel length and arc length for arc-connections, balanced against a minimization of collisions by the connection with existing objects, including other connections.
