    • A device managing apparatus that can easily communicate under a proper communication configuration, through a network may be provided. A managing apparatus (10) is provided with a storage (14) and a controller (CPU executing a management program) (12). The storage (14) stores multiple different communication configurations. The controller (12) controls the communication with the device. The controller (12) carries out the following processes: (1) repeating a communication trial toward the device using one of stored communication configurations that are stored in the device managing apparatus, in which the communication configuration to be used is changed for each communication trial;. (2) monitoring a response which is sent to the device managing apparatus from the device in a case where the communication trial has succeeded; and (3) displaying a plurality of areas, each of which is linked to each of the stored communication configurations; and displaying a symbol image representing the device in the area that is linked to the communication configuration with which the communication trial has succeeded. By using the device managing apparatus, the user can easily recognize, at a glance of the screen, devices at which the same communication configurations are set.

    • We formulate the network-wide traffic measurement/analysis problem as a series of set-cardinality-determination (SCD) problems. By leveraging recent advances in probabilistic distinct sample counting techniques, the set-cardinalities, and thus, the network-wide traffic measurements of interest can be computed in a distributed manner via the exchange of extremely light-weight traffic digests (TD's) amongst the network nodes, i.e. the routers. A TD for N packets only requires O (loglog N) bits of memory storage. The computation of such O (loglog N) -sized TD is also amenable for efficient hardware implementation at wire-speed of 10Gbps and beyond. Given the small size of the TD's, it is possible to distribute nodal TD's to all routers within a domain by piggybacking them as opaque data objects inside existing control messages, such as OSPF link-state packets (LSPs) or I-BGP control messages. Once the required TD's are received, a router can estimate the traffic measurements of interest for each of its local link by solving a series of set-cardinality-determination problems. The traffic measurements of interest are typically in form of per-link, per-traffic-aggregate packet counts (or flow counts) where an aggregate is defined by the group of packets sharing the same originating and/or destination nodes (or links) and/or some intermediate nodes (or links). The local measurement results are then distributed within the domain so that each router can construct a network-wide view of routes/ flow patterns of different traffic commodities where a commodity is defined as a group of packets sharing the same origination and/or termination nodes or links. After the initial network-wide traffic measurements are received, each router can further reduce the associated measurement/estimation errors by locally conducting a minimum square error (MSE) optimization based on network-wide commodity-flow conservation constraints.
