Method and apparatus for providing node security in a router of a packet network
First Claim
1. A method for providing node security in a router of a packet network, comprising the steps of:
- monitoring a data packet sent from an originator via the router and addressed to a destination device other than the router;
determining in the router whether the data packet is potentially harmful to the destination device;
interrupting transmission of the data packet in response to determining that the data packet is potentially harmful to the destination device, comprising the step of communicating with a second router to cause the second router to interrupt transmission of a future data packet; and
transmitting the data packet in response to determining that the data packet is not potentially harmful to the destination device.

Abstract
A router (200) monitors (302) a data packet sent from an originator (102) via the router and addressed to a destination device (112, 116) other than the router, and determines (304) whether the data packet is potentially harmful to the destination device. The router interrupts (306) transmission of the data packet in response to determining that the data packet is potentially harmful to the destination device, including communicating (307) with a second router to cause the second router to interrupt transmission of a future data packet; and transmits (308) the data packet in response to determining that the data packet is not potentially harmful to the destination device.

11. A router for providing node security in a packet network, comprising:
-
a plurality of I/O ports for accepting a data packet sent from an originator via the router and addressed to a destination device other than the router, and for transmitting the data packet to the destination device; and
a processor coupled to the plurality of I/O ports for processing the data packet;
wherein the processor is programmed to;
monitor the data packet;
determine whether the data packet is potentially harmful to the destination device;
interrupt transmission of the data packet in response to determining that the data packet is potentially harmful to the destination device, including communicating with a second router to cause the second router to interrupt transmission of a future data packet; and
transmit the data packet in response to determining that the data packet is not potentially harmful to the destination device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
