An information processing device in a communication apparatus performs a management process of traffic flow management information for transfer of data including a plurality of frames from a transmission source terminal to a transmission destination terminal. Where new traffic flow management information of a traffic flow associated with a data frame identified by an identification unit on the basis of identification information included in the received data frame is recorded in the communication apparatus, a recording unit determines whether the number of pieces of traffic flow management information already recorded is equal to or more than a threshold value, and calculates and records a scheduled release time of the traffic flow management information according to a determination result.

Information processing apparatus, communication apparatus, information processing method and program

SeNBs generate first identification information for specifying wireless access networks on the basis of system information provided in a notification from a relay communication device, wirelessly transmit the first identification information to UE, and notifiy an MeNB of second identification information for specifying wireless resources, utilization of which is permitted, via the relay communication device. The MeNB sets, in a signal directed to an SeNB selected from the SeNBs in the first identification information received from the UE, the first identification information of the SeNB, sets the second identification information of the selected SeNB in the signal directed to the UE, and transmits the signal to the relay communication device. The relay communication device transfers the signal received from the master base station to the SeNB in accordance with the first identification or the second identification information set in the signal. The SeNB wirelessly transmits the signal transferred from the relay communication device and directed to the UE.

Wireless communication system, relay communication device and communication control method

Provided are a control apparatus, a control method, and a program capable of designing efficient end-to-end monitoring in a VPN infrastructure. The control apparatus according to the present invention controls end-to-end monitoring in a VPN infrastructure in which communications of a plurality of users are superimposed. The control apparatus includes a user end databasethat stores information about customer edge apparatuses (CEs) for each of the users, each of the CEs serving as a monitoring end of end-to-end monitoring, an end-to-end path databasethat stores information about all links included in a path between the CEs, and an end-to-end monitoring management unitthat sets a monitoring path for end-to-end monitoring to between the CEs so that combinations of the monitoring path passing through each of the links are coprime.

Control device, control methods and programs

An object is to provide a communication device, a communication method, and a program that make it possible to suppress an increase in the communication band due to communication via a GWR when Dual Connectivity is implemented, without making an additional setting on base stations. A communication device according to the present invention enables a communication packet to be transferred through a path that is shorter than conventional paths, and can therefore suppress an increase in the communication band. Also, this short cut of the communication path need only be set on the communication device, and need not be additionally set on the base stations.
