At normal times, each of the virtual machines of the plurality of disaster recovery stations repeatedly receives data related to call processing from a corresponding active station of the plurality of active stations at a predetermined timing.

A management device (10) includes: a management table acquisition unit (132) that acquires at least a first management table in which an MPLS tunnel and a first label for in-network delivery are associated with each other, and a second management table in which an MPLS tunnel, a second label for specifying a CE router that is an output destination from an egress PE router, and identification information of a VPN to which the CE router that is the output destination belongs are associated with each other, the first management table being included in a node that is a copy source in an MPLS network, the second management table being included in an egress PE router as an output destination of a packet; and a VPN identification unit (133) that collates the first label of the copied packet with the first management table to identify an MPLS tunnel through which the packet passes, identifies the egress PE router to which the packed is output based on the MPLS tunnel, and identifies the VPN of the packet by collating the second management table of the egress PE router with the second label attached to the packet.

A communication latency measurement apparatus (10) includes a packet generation unit (12) that generates an SRT packet (packet) to be transmitted to an NW 30 to which a plurality of routers (1r to 6r) by recording path information including an ID of a router serving as a round-trip transfer destination of the packet, a time keeping unit (13) that keeps a time, a transmission/reception unit (11) that records a time kept when the packet is transmitted and/or received as a timestamp for each of transmission and reception in the generated packet, a latency calculation unit 14 that calculates a latency time on a round-trip path from a difference between the transmission and reception timestamps recorded in the received packet and store the latency time in a DB 15 in association with the path information, and a specific segment latency calculation unit 17 that calculates a latency time in a specific router segment from a difference between the stored latency time information of a round-trip path (arrow Y2) including a specific router segment (for example, the segment between routers r1 and r2) and latency time information of another round-trip path (arrow Y3).

A service provision system (10) comprises a service mesh (11) including a plurality of microservices (12), and a master node (20) that manages each of the microservices (12), and includes a task processing monitoring unit that monitors a task processing status in each of the microservices (12), a processing ratio determination unit that determines, on the basis of the task processing status in each of the microservices (12), a ratio of requests on which to perform normal task processing and requests for which to return an error from among service requests received by a most upstream microservice (12A), and a worker allocation unit that increases the number of workers in the most upstream microservice (12A) in a case where the congestion occurs.

A communication device includes a storage unit that stores a conversion table; a receiving unit that receives a packet addressed to a user terminal from a server, and an address conversion unit that converts a destination address of the packet into a multicast address in accordance with the conversion table, adds, to the packet, an identification ID for identifying a group to which the user terminal belongs, and transmits the packet to which the identification ID is added.

An object is to provide a network management system and the like capable of being introduced into an existing network to ascertain an instantaneous traffic variation in the network. The scheme of the present invention uses a shaping function included by each edge apparatus. The shaping function controls packet transmission in a millisecond order. The network management apparatus according to the present invention adds up the amount of transmitted packets for each control period reported by each edge apparatus and estimates this as an instantaneous traffic amount in the network. In the scheme, it is only necessary to add one network management apparatus to an existing network and to cause each edge apparatus to report the amount of transmitted packet to the network management apparatus.

In a signal transfer system including a signal transfer management apparatus and a plurality of signal transfer apparatuses connected in multiple stages and forming a network between a distribution station apparatus and a central station apparatus, a signal transfer apparatus on an upper side among the plurality of signal transfer apparatuses transmits a timing adjustment request to at least one of a plurality of signal transfer apparatuses on a lower side among the plurality of signal transfer apparatuses upon determining that there is a possibility that a microburst occurs according to mobile scheduling information received from the plurality of signal transfer apparatuses on the lower side, and the signal transfer apparatus on the lower side that has received the timing adjustment request from the signal transfer apparatus on the upper side adjusts opening and closing timings of a gate based on the timing adjustment request. This can prevent the occurrence of a microburst.

[Object] To provide an information processing apparatus and an information processing system that make it possible to play a game smoothly while using a mobile communication system.

[Solving Means] An information processing apparatus according to the present technology includes a control section and a communication section. The control section selects a slice according to a genre of a game for which a request for information that is necessary for game play is made by a terminal, and assigns, to the information, an identifier that indicates the slice used to communicate the information. The communication section transmits the information to the terminal through a communication network.

A restoration determination device 1 calculates, based on past traffic data of each user in a first NW device, a current estimated traffic amount of the user, compares the calculated current estimated traffic amount of the user with a current traffic amount of the user in a second NW device to which the first NW device is switched, and determines restoration by switching to the second NW device to be abnormal when the number of users for which the current estimated traffic amount is larger than zero but the current traffic amount is zero exceeds a threshold value.
