    摘要: A method of configuring a data processing system for facilitating network communications involves creating a primary logical partition (LPAR) in the data processing system, the LPAR configured to host a specified operating system. The method further includes creating a first virtual network adapter within the LPAR, associating the first virtual network adapter with a first network address, and binding the first virtual network adapter to the LPAR. The method additionally involves creating a first logical subpartition (LSPAR) within the LPAR, the first LSPAR configured to employ said specified operating system and no other. The method also includes creating a second virtual network adapter within the LPAR, associating the second virtual network adapter with a second network address, wherein the second network address is not an alias network address of the first network address, and binding the second virtual network adapter to the first LSPAR.

    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: A computer implemented method, computer program product, and system for creating a checkpoint of a stream. A stream checkpoint request to create the checkpoint of the stream is received, wherein the stream is used by a process as a communications path, and wherein the communications path is modified by a set of modules. In response to identifying the identity of each module in the set of modules, the identity of each module in the set of modules is stored in the checkpoint. In response to identifying an order of the set of modules, the order of the set of modules is stored in the checkpoint. In response to sending a stream checkpoint message to each module in the set of modules, module data is received from each module in the set of modules to form received module data. The received module data is stored in the checkpoint.
