Patent number: 8054840Abstract: A method, system and service for a data center computer network. A core network switches data using a first protocol layer. A first access switch is in electrical communication with the core network. The first access switch communicates the data to the core network using the first protocol layer. A second redundant access switch forms a first access switch pair with the first access switch. The second access switch is in electrical communication with the core network and communicates the data using the first protocol layer. The second access switch is in electrical communication with first access switch and communicates with the first access switch using a second protocol layer. The second protocol layer is at lower OSI level than the first protocol layer. The first access switch and the second access switch are configured to form a first VLAN. A first edge device is in electrical communication with the first access switch and the second access switch. The first edge device is part of the first VLAN.Type: GrantFiled: June 12, 2007Date of Patent: November 8, 2011Assignee: International Business Machines CorporationInventors: Bruce Booth, William B.

Patent number: 7991914Abstract: A single firewall or cluster of firewalls with a public IP address is interfaced to an internet public subnet to receive service requests for a cluster of network servers. A first private subnet with a plurality of private IP addresses is interfaced to the single firewall or cluster of firewalls to receive the service requests after passing through a firewall. A plurality of redundant load balancers with a respective plurality of private IP addresses are interfaced to the first private subnet to receive the service requests after passing through the first private subnet. The load balancers are interfaced to a second private subnet. The network servers with respective private IP addresses are interfaced to the second private subnet to receive the service requests from the load balancers.

Patent number: 7936743Abstract: A system, computer program and method to determine a transmission path of a datagram in an IP network from a source device to a destination device. The source device sends a datagram to an IP network device along the transmission path to the destination device. The datagram comprises as destination address, the IP address of the destination device and as source address, the IP address of the network manager station. Consequently, replies, if any, to the datagram are sent back directly to the network manager station by the IP network device along the transmission path, bypassing the source device.Type: GrantFiled: April 29, 2008Date of Patent: May 3, 2011Assignee: International Business Machines CorporationInventors: Eric LeBrun, Arnaud Lund

Patent number: 7908355Abstract: A method for improving network server load balancing in a system that has a plurality of network servers connected by an Internet access LAN to the Internet, a back-end access LAN connected to several database servers, and a network load balancer for selecting one of the network servers according to weights associated with the network servers. Link connectivity is monitored cyclically from each network server, and a status indicator is set to UP if all of the links associated with the network server are available, or to DOWN if at least one link is unavailable. The network servers send their status indicators to the network load balancer. The network load balancer changes the weight associated with a network server to a non-eligible value if the associated status indicator changes from UP to DOWN.Type: GrantFiled: June 12, 2003Date of Patent: March 15, 2011Assignee: International Business Machines CorporationInventors: Pascal Chauffour, Eric Lebrun, Valerie Mahe
