Abstract: A transmission apparatus includes: a sending unit configured to send data to a receiver apparatus via the network; a receiving unit configured to receive acknowledgement data including an acknowledgement and information on a receive window size from the receiver apparatus via the network; a transmission bandwidth controller configured to control a bandwidth for data to be sent from the sending unit; a transmission bandwidth restriction unit configured to restrict the bandwidth controlled by the transmission bandwidth controller in such a manner that a data size of data for which no acknowledgement is received from the receiver apparatus among data which is sent is equal to or smaller than an upper limit size determined from the receive window size; and a switching controller configured to switch activation and inactivation of the transmission bandwidth restriction unit based on the data size and the receive window size.

Abstract: An analysis device analyzes a packet processed by a communication device connected with a network. The analysis device includes a receiver and an analyzer. The receiver receives a mirror packet of the packet transmitted through the network. The analyzer obtains and analyzes a portion of information in the mirror packet, and determines a necessity or lack thereof for a function of the communication device to be performed on the packet transmitted through the network based on analysis results of the analyzer.
