Abstract
A method for managing attacks in a computer system is disclosed. The computer system is used in sending, receiving, or sending and receiving a plurality of packets, which include a plurality of administrative packets. The method includes determining whether a congestion of the administrative packets exists. Congestion of the administrative packets indicates that a potential attack exists. The method also includes discarding a portion of the plurality of administrative packets if it is declared that the congestion of the administrative packets exists. The portion of the plurality of packets is sufficient to ensure that a remaining portion of the plurality of packets transmitted is not more than a maximum administrative packet bandwidth limit and, if the plurality of administrative packets present a sufficient offered load, not less than a minimum administrative packet bandwidth guarantee.
