International Classification:

G06F 13/24

US Classification:

710260, 710266, 710261, 370463

Abstract:

Provided are a method, system and article of manufacture for adjusting interrupt levels. A current system interrupt rate at a computational device is determined, wherein the current system interrupt rate is a sum of interrupt rates from a plurality of interrupt generating agents. The current system interrupt rate is compared with at least one threshold interrupt rate associated with the computational device. Based on the comparison, an interrupt moderation level is adjusted at an interrupt generating agent of the plurality of interrupt generating agents.

International Classification:

H04L 9/00

US Classification:

713160, 713161, 713176, 713179

Abstract:

A process for comparing data, such as signatures in a data packet, includes retrieving, from a first hash table, a target value that corresponds to a segment of the data, processing the data in accordance with the target value to produce a checksum, locating an entry in a second hash table using the checksum, and comparing the data to the entry.

International Classification:

G06F015/173
G06F015/16

US Classification:

709/223000, 709/229000

Abstract:

A system and method for determining the source, on a network, of unwanted messages generated by a malicious agent, toward a target device such as a web server. The malicious agent directs one or more computers on a sub network to direct a flood of communications toward the server on a second sub network designed to substantially reduce the ability of the server to respond to other communications. Messages passing through points on a path between the malicious agent computers and the server are monitored for indicia of messages uncharacteristic of normal network communication. The first point along the path that the unwanted messages pass through is identified. A network device at that point is instructed to block portion of communications passing through that point.
