A control apparatus configured to control communication between locations includes a database configured to store, for each location, a key and an IP address of CPE in association with each other, a search section configured to receive a CPE address request message including a key of a communication destination from CPE of a certain location and search the database to acquire an IP address of CPE corresponding to the key of the communication destination, and a response section configured to transmit the IP address of the CPE acquired by the search section to the CPE that is a transmission source of the CPE address request message.

A data collection and analysis system includes a communication unit and a data acquisition unit. The communication unit collects data indicating an internal state or operation state of an equipment item. The data acquisition unit acquires, from the communication unit, the data synchronized for each of groups according to setting information, the setting information being information in which the groups, a data acquisition timing, and a storage location of the data are set for a channel allocated to the data to be acquired from the equipment item, each of the groups bringing together a plurality of the channels, the data acquisition timing being a timing at which the data are acquired from the communication unit.

There is set forth herein obtaining data traffic monitoring data, the data traffic monitoring data being in dependence on monitoring of traffic received by a container of a protected computing environment; obtaining data traffic monitoring data, the data traffic monitoring data being in dependence on monitoring of traffic received by a processing resource of a computing environment; obtaining a state of the processing resource and provisioning a utility processing resource to include the state of the processing resource; and configuring the computing environment to route data traffic to the utility processing resource.

The techniques describe example network systems providing core-facing designated forwarder (DF) election to forward multicast traffic into an EVPN of a core network. For example, a first PE device of a plurality of PE devices participating in an EVPN comprises one or more processors operably coupled to a memory, wherein the one or more processors are configured to: determine that a first multicast traffic flow has started for the first PE device; in response, send a source-active (SA) route to indicate the first multicast traffic flow has started for the first PE device; receive, from a second PE device, a second SA route that indicates that a second multicast traffic flow has started for the second PE device; and perform an election of a core-facing DF from among the first PE device and second PE device, wherein the core-facing DF is configured to forward the multicast traffic into the EVPN.

A path information managing apparatus includes a storage unit configured to store, in association with a virtual IP address, a locator of each of a plurality of aggregation routers and a locator of each of a plurality of virtual accommodation routers that are accommodated in each aggregation router and accommodate cluster, an acquisition unit configured to acquire the locator of the aggregation router associated with the virtual IP address and the locator of each virtual accommodation router, in response to an inquiry for a virtual IP address to a destination of a packet, the inquiry being transmitted from an accommodation router that receives the packet from a terminal, and a transmission unit configured to transmit, to the accommodation router, the acquired locator of the aggregation router, the acquired locator of each virtual accommodation router, and a weight of each virtual accommodation router, or the locator of any virtual accommodation router.

A time stamp correction apparatus 1 that corrects a deviation between time stamps of pieces of data acquired by physically connected NW apparatuses 50A and 50B by correcting a deviation in a time stamp between pieces of traffic data is provided. The time stamp correction apparatus 1 includes a waveform similarity computation unit 13 that determines an IF pair based on a similarity between waveforms of time-series data of traffic observed in respective interfaces of the NW apparatuses 50A and 50B, and a time stamp correction unit 14 that generates correction information for correcting a deviation between the time stamps of the pieces of data based on feature points of time-series data of traffic observed in the IF pair.

A network management device according to one embodiment includes a device that stores rules for mapping between a service order and a resource order; a device that stores, when a mapping is performed based on the mapping rules, a mapping history in which an identifier of a service for the service order which is a mapping source, a type of a rule used for the mapping, and an identifier of a resource for the resource order which is a mapping target are described; and a creation unit that, when a service order to change the service is created, acquires, from the mapping history and the identifier of the service to be changed, information indicating types of rules to be used for mapping of the service order to change the service and the identifier of the resource for a resource order which is a mapping target, and creates a resource order by mapping of the order to be changed based on the acquired mapping rules.

A communication apparatus which terminates an L2 tunnel and an L3 tunnel includes a table storage unit which stores an ARP table where a broadcast MAC address is set as a destination MAC address linked to a destination IP address, and a transmission unit which acquires the broadcast MAC address as a destination MAC address corresponding to a destination IP address of an IP packet received via the L3 tunnel by referring to the ARP table and transmits a frame to which the broadcast MAC address is added as a destination MAC address, via the L2 tunnel.
