Abstract
A node device and method are described to prevent overflow of a pending interest table (PIT). When excessive request messages are received through a particular interface, the node device and method transmits a traffic control message to control a transmission interval of the request messages, which are transmitted to a corresponding interface.
Claims13
A node device, comprising:
- an attack detection unit configured to count a number of request messages received at interface units of the node device during a period of time, and detect an interface unit receiving the request messages among the interface units in response to the number of request messages received exceeding a threshold;
- a traffic control request unit configured to transmit a traffic control message to the detected interface unit, the traffic control message requesting a transmission interval of the request messages;
- and
- an attack managing unit configured to discard request messages received at a transmission interval outside a transmission interval requested by the detected interface unit, when the request messages are received at a transmission interval less than the requested transmission interval and after the response message is transmitted to the detected interface unit.

A method of preventing overflow of a pending interest table (PIT) in a node device, the method comprising:
- counting a number of the request messages received by interface units of the node device;
- detecting an interface unit receiving the request messages during a period of time among the interface units in response to the number of request messages exceeding a threshold;
- transmitting a traffic control message to the detected interface unit, the traffic control message requesting a transmission interval of the request messages;
- discarding request messages received at a transmission interval outside a transmission interval requested by the detected interface unit, when the request messages are received at a transmission interval less than the requested transmission interval and after the transmitting of the traffic control message.
