Patent number: 6009474Abstract: The present invention provides a method and apparatus for re-assigning network addresses to a plurality of network servers by re-configuring a client host coupled to the network servers. According to the invention, when there are changes to network connections, the IP addresses (i.e., network addresses) of the individual network servers can be re-assigned automatically at the client host without powering off the network servers. According to the invention, in re-assigning a new network address to a port of the network server, a bootstrap protocol (BOOTP) request is first issued by the client host to the network server. The BOOTP request is received by the network server which then sends a BOOTP response to the client host to request a new network address. After the client host receives the BOOTP response, it sends a BOOTP reply to the network server. The BOOTP reply includes a new network address for the port of the network server. The above procedure is repeated for each port of the network server.Type: GrantFiled: May 20, 1997Date of Patent: December 28, 1999Assignee: Compaq Computer CorporationInventors: Gin-Pao Lu, Hank Jordan, Paul Chu

Patent number: 5948108Abstract: A method and system for providing a fault tolerant access between network clients and a network server. Accordingly, a preferred embodiment of the present invention, a first primary input/output process (IOP) and a second backup IOP are provided in a first network client. A first backup IOP and a second primary IOP are provided in a second network client. The first backup IOP is a backup of the first primary IOP and the second backup IOP is a backup of the second primary IOP. A first preferred access path between the first primary IOP and the network server as well as a first alternate access path between the first backup IOP and the network server are defined. Similarly, a second preferred access path between the second primary IOP and the network server as well as a second alternate access path between the second backup IOP and the network server are defined. A first network connection between the first primary IOP and the network server is established via the first preferred access path.Type: GrantFiled: June 12, 1997Date of Patent: September 7, 1999Assignee: Tandem Computers, IncorporatedInventors: Gin-Pao Lu, Hank Jordan, Paul Chu

Patent number: 5585081Abstract: A method for controlling emissions of a fossil fuel fired boiler including a high temperature fabric filter house with an SCR catalyst situated therein for receiving flue gases along with an injected ammoniacal compound and sorbent. The sorbent reacts with the SO.sub.x while the ammoniacal compound reduces the NO.sub.x in the presence of the SCR catalyst inside the high temperature fabric filter house. Both the SO.sub.x and the particulates are removed upstream of the SCR catalyst to diminish the problems of SO.sub.2 or SO.sub.3 poisoning of the catalyst and erosion and fouling of the catalyst with the fly ash. Since the sulfur oxides and particulates are removed prior to the heat recovery system, the fouling and corrosion potential are substantially decreased thus allowing the heat recovery system to be operated at a lower outlet flue gas temperature which yields an incremental improvement in energy recovery.Type: GrantFiled: April 3, 1990Date of Patent: December 17, 1996Assignee: The Babcock & Wilcox CompanyInventors: Paul Chu, William Downs, John B. Doyle, Peter V. Smith
