Abstract:
1. A node device comprising: interface units configured to receive a request message from a name based network; pending interest tables (PITs) configured to store the request message, each of the PITs matching a respective interface unit; a control unit configured to identify one of the interface units receiving the request message, identify the PIT matching the identified interface unit, and control the identified PIT to store the request message; and an attack detection unit configured to determine a capacity used at the identified PIT and detect an attack through the identified interface unit based on the determined capacity, wherein the attack detection unit is configured to detect whether the determined capacity exceeds a predetermined threshold; and a traffic control request unit configured to transmit a traffic control message to the identified interface unit when the attack detection unit detects the determined capacity exceeding the predetermined threshold, the traffic control message requesting control of a transmission interval of request messages.
