  • Patent number: 9634985
    Abstract: Facilitating communications within a processing environment. Inbound traffic and outbound traffic on one or more virtual interfaces of the processing environment are monitored for a predefined amount of time. Based on the monitoring, a determination is made as to whether for a selected component of a virtual interface of the one or more virtual interfaces an inbound frame has been received but an outbound frame has not been transmitted for the predetermined amount of time. Based on determining that the inbound frame has been received but the outbound frame has not been transmitted, a generated outbound frame is forwarded to cause address registration information for the virtual interface to be refreshed.

  • Publication number: 20120207031
    Abstract: A physical host executes a virtual machine monitor (VMM) that instantiates a source virtual machine (VM). In response to the VMM receiving from the source VM a packet specifying a first destination address of a destination VM and a second destination address of a default gateway, the VMM determines whether the packet can be communicated to the destination VM without the packet being routed by the default gateway. In response to the VMM determining that the packet can be communicated to the destination VM without the packet being routed by the default gateway, the VMM forwards the packet to the destination VM such that the packet bypasses routing by the default gateway.

  • Patent number: 7831867
    Abstract: The present invention provides a system and method for controlling tracing functions on a remote device. The system includes means for receiving a diagnostic signal from a host device on the remote device and means for associating the diagnostic signal with a tracing state of the remote device. In addition, the system includes means for performing a tracing function indicated by the diagnostic signal. The present invention can also be viewed as a method for controlling tracing functions on a remote device. The method operates by receiving a diagnostic signal from a host device on the remote device and associating the diagnostic signal with a tracing state of the remote device. Then, the method performs a tracing function indicated by the diagnostic signal.

  • Publication number: 20060090116
    Abstract: Method, system and computer program product for protecting the integrity of data transferred between an input/output bus of a data processing system and an external network. A method for protecting the integrity of data transferred between an input/output bus and a network includes generating a Cyclic Redundancy Check (CRC) value on an interface between the input/output bus and an adapter for data being transferred from the input/output bus to the network, and checking a CRC value on the interface between the input/output bus and the adapter for data being transferred from the network to the input/output bus. By adding a CRC generator and a CRC checker on the interface between the input/output bus and the adapter, end-to-end data integrity protection is provided for data transferred between the input/output bus and the network.

  • Publication number: 20060045089
    Abstract: A network virtualization layer for an information handling system in which a physical machine coupled to a network is divided into a plurality of logical partitions, each of which has a host system residing thereon. In response to receiving a set command from one of the host systems specifying a data link layer (layer 2) address, the virtualization layer associates the data link layer address with the host system and forwards to the host system data packets specifying the data link layer address as a destination address. Unicast packets are forwarded to the single host system specifying the destination address as an individual MAC address, while multicast packets are forwarded to each host system specifying the destination address as a group MAC address. A host system may also specify a virtual LAN (VLAN) ID, which is used to scope the forwarding of packets to host systems sharing that VLAN ID.

  • Publication number: 20050267967
    Abstract: The substantially simultaneous tracing/monitoring of a plurality of sets of events via a single network interface. The plurality of events can be traced and/or monitored for one host or for a plurality of hosts coupled via the same network interface. The sets of events to be traced/monitored for a host are defined by the host and maintained in one or more configuration files. The configuration files may be dynamically updated.

  • Publication number: 20050220072
    Abstract: An active node of a communications network includes a forwarding component for forwarding a packet of an active application, a processor for processing the packet, and a forwarding control component for modifying path data associated with the packet, based on the processing. The forwarding component can forward said packet directly to the network or via the processor. The processing can include executing code contained within the packet, and/or executing code to process application data in the packet. The path data can include the MPLS label stack of the packet and/or MPLS tables of the forwarding component. To allow processing based on multiple labels of a packet, the forwarding component can include a loopback connection between its input and output ports.
