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.

Provided are a router and a method of controlling a maximum transmission unit (MTU) of an external network interface. The router controls the MTU by disassembling packet data segments of a predetermined size and assembling the data segments of the predetermined size into the original packet data structure when the external network interface physically included in a linecard processor has an MTU that is greater than that of an internal data communication channel of the router, so that the external network interface can transmit and receive data with another router without being affected by the MTU of the internal data communication channel in the operating system of the router.
