Patent number: 7447197Abstract: A network node for processing messages transmitted via a network, the node including: a first circuit providing a processor-based node path; a second circuit, coupled to the first circuit, providing a switch-based node path; and a memory storing mapping information accessible by the first and second circuits, wherein the processing of messages received by the network node is allocated between the first and second circuit based on the mapping information.Type: GrantFiled: April 4, 2005Date of Patent: November 4, 2008Assignee: QLOGIC, CorporationInventors: William Clinton Terrell, Wayland Jeong, William W.

Patent number: 7389399Abstract: A network interface for secure virtual interface data communication includes a doorbell circuit, a processor, memory, and a bridge circuit. The doorbell circuit responds to physical I/O addresses of the host that are mapped by a memory management unit by a registration process. An application program seeking to use a channel of a virtual interface must register the virtual address of host memory where data for communication is or will be stored and register the virtual address of a page of I/O addresses. Access to the doorbell functions and to the host memory via the memory management unit are therefore denied when the requesting process identifier does not successfully compare with the process identifier for the process that performed the registrations. A password may be stored in the network interface in association with a virtual interface (VI) channel identifier and stored in association with the virtual to physical map used for VI communication.Type: GrantFiled: March 1, 2005Date of Patent: June 17, 2008Assignee: QLOGIC, CorporationInventors: William C.

Publication number: 20080008202Abstract: A router for use in a network includes a scalable architecture and performs methods for implementing quality of service on a logical unit behind a network port; and for implementing storage virtualization. The architecture includes a managing processor, a supervising processor; and a plurality of routing processors coupled to a fabric. The managing processor has an in-band link to a routing processor. A routing processor receives a frame from the network, determines by parsing the frame, the protocol and logical unit number, and routes the frame to a queue according to a traffic class associated with the logical unit number in routing information prepared for the processors. An arbitration scheme empties the queue in accordance with a deficit round robin technique. If a routing processor detects the frame's destination is a viral entity, and so is part of a virtual transaction, the router conducts a nonvirtual transaction in concert with the virtual transaction.Type: ApplicationFiled: September 24, 2007Publication date: January 10, 2008Inventors: William Terrell, Tracy Edmonds, Wayland Jeong, Eric Peterson, Jean Kodama, Harun Muliadi, Norman Chan, Rexford Hill, Michael Nishimura, Stephen How
