A packet capture apparatus includes a hardware processing unit including a filter that filters packets input from a network and an NIC and a packet storage that stores packets input from the hardware processing unit. The filter includes a packet input that receives packets input from the network, a header analysis unit that analyzes a header structure of each packet input to the packet input unit and extracts a field value of a header of the packet, a rule table in which rules including a field value of a flow to be captured are recorded, a flow identification unit that identifies a flow in which the field value extracted by the header analysis unit matches a rule in the rule table and/or does not match the rule, and a packet output that outputs a packet of the flow identified by the flow identification unit to the NIC.

A management apparatus, which communicates with a terminal apparatus that is connectable to a network controlled by QoS control, includes: an acquirer configured to acquire protocol information indicative of processing content of a connection protocol to be performed between the terminal apparatus and the network when the terminal apparatus is connected to the network; a transmission controller configured to transmit based on the connection protocol, to the terminal apparatus, one or both of interface information relating to a reception of a start request for the QoS control of one network, and address information relating to a reception of an acquisition request for the interface information.

Provided are a failure detection system, a failure recovery system, a failure detection method, and a non-transitory computer readable medium that are capable of more easily estimating a degradation location of QoE. A failure detection system (10) is provided with a log collection unit (12) that collects a communication log including communication quality information from a relay device that terminates TCP communication, and a degradation estimation unit (16) that estimates, by using the communication quality information of the collected communication log, a degradation point indicating a point where a communication quality degradation factor exists in a communication path passing through the relay device.

Embodiments of this application disclose a traffic monitoring method, an apparatus, an integrated circuit, a network device, and a network system. When receiving a first packet, a traffic collection apparatus determines that a measurement value of a target performance indicator of the first packet matches a value of first information in a first register, updates a value of second information in the first register based on the measurement value of the target performance indicator of the first packet, and increases a value of third information in the first register by 1.

A resource management system that includes at least one managed computing system including a plurality of hierarchal computer resources and a server computing system that is coupled to the at least one managed computing system through a network. The server computing system includes a broker in communication with a plurality of providers. The broker is configured to receive a Uniform Resource Identifier (URI) request for a first resource of the plurality of hierarchal computer resources included in the at least one managed computing system. The URI request includes a resource path that identifies the first resource by a hierarchy of a plurality of collections. The broker is configured to determine a last collection in the hierarchy of the plurality of collections that matches a first provider of the plurality of providers, and forward the request directly to the first provider such that the first provider processes the URI request.

A traffic monitoring apparatus that monitors traffic of a monitoring target network and includes a statistical information processor that acquires statistical information per specific flow of the traffic, and a packet capture unit that captures a packet of the specific flow, in which the statistical information processor includes a statistical information aggregation unit that aggregates the pieces of statistical information, and a statistical information file generation unit that generates a statistical information file based on the pieces of aggregated statistical information.

A wireless communication device comprising a communication unit configured to communicate with a wireless communication terminal using a first method to transmit data that is receivable by the wireless communication terminal or a second method, different from the first method, to transmit data that is simultaneously receivable by a plurality of wireless communication terminals including the wireless communication terminal, a processor, and a memory configured to store a program, the program being executable by the processor to cause processor to change a communication rate of the second method based on information indicating an amount of communications traffic of the second method in each of a plurality of unit periods of time is provided. Accordingly, an appropriate multicast transmission rate can be automatically determined.

It is an object of the present disclosure to render each module easily replaceable and facilitate construction of a system in which an existing application has been incorporated. The present disclosure provides a router device including: a routing module that performs a routing process on a packet; a functional module that executes any operation on the packet subjected to the routing process performed by the routing module; and a config module that sets a communication path that connects between the routing module and the functional module.

A non-transitory computer readable medium comprising instructions which causes performance of operations comprising: receiving, by a second network coordination device, current state information of a client device, including a transmit counter and a receive counter, from a first network coordination device, wherein the first network coordination device is a primary network coordination device for the client device and the second network coordination device is a standby coordination device for the client device; and responsive to detecting a particular event, the second network coordination device (i) transitioning to be the primary network coordination device for the client device, (ii) incrementing the transmit counter by an offset, and (iii) transmitting a message to the client device including the incremented transmit counter is shown.

A traffic optimization module includes a profile management component and a data restructuring component, wherein the traffic optimization module is configured to receive, from the UPF, context information that is based on a traffic for a data packet being processed; update traffic history information stored in the profile management component based on the context information; determine whether to perform data restructuring that is based on the traffic history information or not by referring to the traffic history information stored in the profile management component; identify a profile that at least matches a target profile requested by the data restructuring component from among the plurality of profiles; restructure a data set included in the identified profile as a data set including data required for processing the context information; and provide the identified profile including the restructured data set to the profile management component.
