Abstract: A system and method according to the invention provide an efficient resource allocation when receiving connection requests from different servers for data transfer and the efficient resource allocation is achieved by identifying and assigning a quality factor to each originating server. When an originating server presents an abusive behavior, it may be assigned to a state that has a low quality factor, thus receiving little resource from the system.

Abstract: A system and method for processing data streams is disclosed. The system receives data packets for data streams, screen the data packets for searched patterns, and forward the data packets for their respective stream processing. Generally, the data packet is scanned for viruses before being forwarded for further processing. When an out-of-order data packet is received, a copy is made and the data packet is forwarded without being scanned. When a delayed data packet is received, it is scanned for virus along with the saved copy of the out-of-order data packet. If a virus is detected, the delayed packet is dropped and its connection reset. If no virus is found, the delayed packet is forwarded for further processing.

Abstract: An apparatus and method for enabling rapid transfer of safe data in a data communication network. The apparatus includes a plurality of query modules, a search window, a shift detector, and a database of unsafe data. A predetermined portion of the unsafe data's signature is populated into the query modules, and the signature of a received data in the search window is compared against a plurality of query modules. The search window is shifted according to the result of comparison with the plurality of query modules detected by the shift detector.

Abstract: An apparatus and method for identifying undesirable data received from a data communication network. The apparatus includes a data receiver, a database, and a content search unit. The content search unit transitions among a plurality of internal states depending on the received data. A predetermined segment of the received data compared with a state table for a current state of the content search unit. If there is a match, the content search unit moves to a next valid state. If there is no match, the content search unit moves to a failure state. When the content search unit reaches a final state, the undesirable data is identified.
