摘要： A method for negotiating a protocol for a conversation in which data packets are transmitted. Responsive to establishment of a link aggregation with an endpoint for the conversation, an algorithm for processing the data packets in the conversation is selected to form a preferred algorithm. A request is sent to the endpoint. This request indicates the preferred algorithm for processing the data packets in the conversation. A reply to the request is received from the endpoint. A determination is made as to whether a convergence has occurred. The data packets in the conversation are processed using the preferred algorithm in response to a determination that the convergence has occurred.

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, data processing system, and computer usable code are provided for protocol definition for software bridge failover. In a first aspect of the present invention, a first software bridge determines the proper working operation of a physical adapter. Limbo packets are sent to a second software bridge alerting the second software bridge that the first software bridge is no longer bridging traffic responsive to the physical adapter failure in the first software bridge. The second software bridge receives the limbo packets, and, in response to receiving the limbo packets, asserts primary control and initiates bridging of traffic. In an alternative aspect of the present invention a first software bridge sends keep-alive packets. A second software bridge monitors the keep-alive packets from the first software bridge and, in response to a failure to detect the keep-alive packets from the first software bridge, the second software bridge initiates bridging of traffic.

摘要： A computer-implemented method, an apparatus, and a computer-usable program product for identifying a link status for a virtual adapter in a logical partition framework are provided. A partition management firmware receives a signal identifying a communication disruption in a link associated with the virtual adapter within the logical partition framework. The partition management firmware identifies which links associated with the virtual adapter are affected by the communication disruption. Responsive to identifying that only a physical link associated with the virtual adapter is disrupted, the partition management firmware categorizes the link status for the virtual adapter as partial link-down. Responsive to identifying that both the physical link and a virtual link associated with the virtual adapter are disrupted, the partition management firmware categorizes the link status for the virtual adapter as link-down.

摘要： A system, apparatus and method of aggregating TCP-offloaded adapters are provided. When data is being transacted between a local host and a remote host, associated with the data are usually a local port and a remote port through which the data transaction is to occur. If any one or both hosts have a plurality of TCP-offloaded adapters, the adapters may be aggregated by assigning a common IP address to the adapters. Then an adapter is selected through which the data transaction will occur based on the local port and the remote port. Specifically, the port numbers of the two TCP ports are added together and modded (i.e., the sum-undergoes a modulo operation) by the number of adapters in the aggregation. The result of the modulo operation determines which TCP-offloaded adapter is used to handle the data transaction.
