  • Patent number: 6393475
    Abstract: A method of performing a network management transaction between a network device, having a network management agent installed thereon, and a remote device, having a web-browser installed thereon, is described. The method involves firstly performing a network management function relating to the network device. Data concerning the network management function is then propagated from the agent to the remote device in a format capable of display by the browser. More specifically, a document is propagated from the agent to the remote device for display by the browser, the document incorporating the data concerning the network management function. The document may be an HTML document. Alternatively, the data may be propagated in a format for display by the browser under the direction of an application program resident of the remote device.

  • Patent number: 5825775
    Abstract: A method and apparatus for generating a display containing information about both the local and remote traffic handled by an integrated router/hub is provided. An integrated router/hub routes local messages between devices on a first local area network, and routes remote messages between the first local area network and a second local area network. The integrated router/hub stores a first set of values related to the local messages, and a second set of values related to the remote messages. A network management station executes a network management application the includes instructions which cause the network management station to generate a display of the information stored in the integrated router/hub. In response to user input, the network management station requests the information from the integrated router/hub, receives the information from the integrated router/hub, and generates the display of the information. The display may include charts that illustrate statistics derived from the information.

  • Patent number: 5819028
    Abstract: An apparatus which provides the user with an indication of the computer network's health. The indication is provided by a network management station on the computer network. The network management station has a distributable piece of code which instructs agents to gather diagnostic and status information. The network management station then evaluates the network specific diagnostic and status data gathered by the agents. Based on the evaluation, the network management station generates a representation of the computer network's functionality (i.e., its "health"). Thereby, the user can readily determine whether the computer network requires repairs.

  • Patent number: 5805819
    Abstract: A method and apparatus are provided for grouping the network entities that belong to a network system into logical groups, and generating a display of the network based on the logical groups. In the highest level display, a single visual indicator, such as an icon, is used to represent each logical group. Thus, a display of the entire network system need only contain as many visual indicators as there are logical groups. Typically, the number of logical groups will be significantly less than the number of actual network resources. Consequently, entire large network systems may be displayed without crowding the display screen with small, difficult to read icons. The logical groups are formed based on the type of connections that exist between the various logical entities in the network. Site groups are formed by combining all local area network connections that connection common network entities. Region groups are formed by combining all wide area network connections that connect common network entities.

  • Patent number: 5802286
    Abstract: A method of configuring a network. The network includes some physical devices, some hosts, and a network management tool. The method comprises the following steps. First, generate a set of leaf nodes. Each leaf node includes at least one physical device and connects to at least one host. Next, generate an adjacency matrix from said set of leaf nodes. Next, generate a set of interconnect nodes, the interconnect nodes connect the set of leaf nodes. Next, determine the resource availability for the set of interconnect nodes. Finally, configure the set of interconnect nodes and the set of leaf nodes after determining that sufficient resources are available.
