摘要： Systems and methods for providing a network monitoring tool for appropriately grasping a setup state of a label switched path (LSP) in a network. A monitoring apparatus comprises a communication unit that communicates with a router among a plurality of routers in the network, and a collection unit that collects LSP path information via the communication unit. The LSP path information includes information maintained by the router. The monitoring apparatus also comprises a storing unit that stores state information based on the collected LSP path information, and a display unit that reads the state information for a selected LSP stored by the storing unit and graphically displays a path of the selected LSP, in accordance with a user's instruction.

摘要： Systems and methods for visualizing traffic coming in from outside to a network to be managed and being sent out of the network. An information presentation apparatus acquires traffic information regarding a traffic specified in accordance with a user's instruction, where the traffic information has been collected from one or more routers located at a border of the network to be managed. The apparatus also acquires path information regarding a path from a start router, through which the traffic passes into the network, to an end router, through which the traffic passes out of the network, referring to stored internal path information. The apparatus then informs a user of the acquired traffic information in association with the acquired path information. At least one of specification of the traffic and determination of the end router is performed referring to stored external path information.

摘要： Measurement servers and a presentation server are provided such that, in an internet comprising a plurality of networks, a communication quality provided by each network in relation with another network can be measured and a user can grasp it with a bird's-eye view as required. Each of the measurement servers is located at each network, and the presentation server collects information from the measurement servers. Each measurement server sends a measurement packet toward another measurement server, receives a response to the measurement packet to acquire information about a network quality of communication with the other measurement server, and sends the acquired information to the presentation server. The presentation server shows a communication quality in accordance with an instruction from a user, based on the received information.

摘要： A mechanism for performing multicast packet transfer when a certain one of the destination nodes participating in the multicast communication requires resource reservation for a certain packet flow specified among the packet flows to that destination node. A system may transfer multicast packets using a plurality of virtual connections based on which flow the packets to be transferred belong to, so that each node receives the packets without duplication. Alternatively, a system may selectively discard received packets to avoid processing duplicated packets, although duplicated packets are received at each node.

摘要： A part of the elements discovered in a network are chosen to be monitored, and a user such as a network administrator is allowed to appropriately monitor desired elements. A network management server collects information on elements in the network, and displays collected information on a GUI screen. The user is allowed to choose an element based on the information displayed on the screen, and the element chosen by the user is then registered as an object to be monitored. Information is collected including elements which are not registered, and displayed on the screen along with a result of comparison to the registered elements.
