1. A relay apparatus for transferring data between a terminal on which an application for carrying out communication by using TCP runs and a server for transmitting data requested by the application,
the relay apparatus comprising: a processor; a memory coupled to the processor; a plurality of network interfaces coupled to the processor and configured to couple to other apparatus, the relay apparatus being configured to be coupled to the terminal via a first network, and be coupled to the server via a plurality of communication routes included in a second network, the relay apparatus including, a TCP management module for monitoring a packet to be transmitted and received by using TCP connection established between the terminal and the server via the first network and one of the plurality of communication routes included in the second network; a determination module for analyzing a request packet in a case where the TCP management module detects reception of the request packet through which the application running on the terminal requests the server to transmit data, and for determining whether or not to switch a communication route of the second network for transmitting the request packet based on a result of the analysis; a request transmission module for establishing new TCP connection to be used by the relay apparatus and the server to carry out communication on a new communication route in a case where the determination module determines to switch to a new communication route of the second network, and for transmitting the request packet to the server by using the new TCP connection; and a data relay module for transferring a data storage packet including the data requested by the application to the terminal by using the new TCP connection. |
