Abstract
Routing apparatus and method for detecting a server attack are disclosed. The routing apparatus includes: a reception unit configured to receive a packet transmitted in a network; a transmission unit configured to transmit the packet along a transmission path; a memory unit configured to store data and/or information required for an operation; and a controller configured to set the transmission path of the packet in the network and perform packet switching along the set transmission path, wherein the reception unit receives server state information from servers at every certain time, the memory unit stores the received server state information, and the controller calculates a change in the state of the servers based on the received server state information, and determines that a server is attacked when a change in the state of the server is greater than a certain threshold value.
