摘要： In some example embodiments, there is a method for failback to a primary communications adapter. The method includes receiving, in a driver for the primary communications adapter and a backup communications adapter, a link up event for the primary communications adapter, wherein the link up event is sent from the primary communications adapter to the driver, and wherein the link up event is triggered by establishing electrical connectivity to the primary communications adapter. The method includes inferring that the primary communications adapter is configured for receiving packets. The method includes setting the backup communications adapter to idle, wherein the backup communications adapter receives packets and drops the packets while idle. The method includes activating the primary communications adapter, wherein the primary communications adapter receives packets and passes the packets up a protocol stack while activated.

摘要： A method, computer program product, and data processing system for efficiently discovering and storing path MTU information in a sending host are disclosed. In a preferred embodiment, two path MTU tables are maintained. One path MTU table contains MTU values corresponding to the first-hop routers associated with the sending host. The other path MTU table contains MTU values corresponding to individual destination hosts. When the sending host needs to send information to a destination, it first consults the MTU table associated with individual destination hosts. If an entry for that destination host is found in the table, the sending host uses that MTU value. If not, the sending host consults the MTU table for the first-hop router on the path to the destination host and uses that MTU value. If that MTU value is too high, a new entry is made in the host-specific MTU table for the destination host.

摘要： An approach is provided in which a computer system selects a virtual domain from multiple virtual domains, which are each overlayed onto a physical network and are independent of physical topology constraints of the physical network. The computer system selects, from the selected virtual domain, a first virtual group that includes one or more first virtual network endpoints. Next, the computer system selects, from the selected virtual domain, a second virtual group that includes one or more second virtual network endpoints. In turn, the computer system creates a logical link policy that includes one or more actions corresponding to sending data between the first virtual group and the second virtual group.

摘要： An approach is provided which a system selects a first virtual function from a plurality of virtual functions executing on a network adapter that includes a memory area. Next, the system allocates, in the memory area, a memory corresponding to the first virtual function. The system then stores one or more translation entries in the allocated memory partition, which are utilized to send data traversing through the first virtual function. As such, the system sends, utilizing one or more of the translation entries, the data packets from the network adapter to one or more destinations. In turn, the system dynamically resizes the memory partition based upon an amount of the memory partition that is utilized to store the one or more translation entries.

摘要： According to one embodiment of the present disclosure, an approach is provided in which a policy server receives a request for a policy from a requestor. The policy server identifies an initiating virtual machine; the initial virtual machine's corresponding virtual network; and a destination virtual machine. Next, a policy corresponding to sending data from the first virtual machine to the second virtual machine is selected. The policy includes one or more logical references to the virtual network and does not include a physical reference to a physical entity located on a physical network. In turn, a physical path translation corresponding to the selected policy is identified and sent to the requestor.

摘要： In one embodiment a method for migrating a workload from one processing resource to a second processing resource of a computing platform is disclosed. The method can include a command to migrate a workload that is processing and the process can be interrupted and some memory processes can be frozen in response to the migration command. An index table can be created that identifies memory locations that determined where the process was when it is interrupted. Table data, pinned page data, and non-private process data can be sent to the second processing resource. Contained in this data can be restart type data. The second resource or target resource can utilize this data to restart the process without the requirement of bulk data transfers providing an efficient migration process. Other embodiments are also disclosed.

摘要： A computer implemented method, apparatus, and computer program product for dynamically loading a module into an application address space. In response to receiving a checkpoint signal by a plurality of threads associated with an application running in a software partition, the plurality of threads rendezvous to a point outside an application text associated with the application. Rendezvousing the plurality of threads suspends execution of application text by the plurality of threads. The application text is moved out of an application address space for the application to form an available application address space. The available application address space is an address space that was occupied by the application text. A software module is moved into the available application address space.

摘要： A method, computer program product, and data processing system for performing efficient communication between software entities residing in the same operating system using conventional network communications APIs are disclosed. According to a preferred embodiment, when a software entity (e.g., a process) attempts to communicate through a networking API, the operating system determines whether the other end of the communication refers to the same hardware node. If so, the operating system replaces the network protocol connection (socket connection) with a direct interprocess communication construct. The operating system provides additional code to simulate the appearance of an actual network (socket) connection at the API level while performing all actual I/O using the interprocess communication construct.

摘要： A host enables any adapter of multiple adapters of the host to concurrently support any VIPA of the multiple VIPAs assigned to the host. Responsive to a failure of at least one particular adapter from among the multiple adapters, the host triggers the remaining, functioning adapters to broadcast a separate hardware address update for each VIPA over the network, such that for a failover in the host supporting the multiple VIPAs the host directs at least one other host accessible via the network to address any new packets for the multiple VIPAs to one of the separate hardware addresses of one of the remaining adapters.
