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 for selective link aggregation in a virtualized data processing environment is provided in the illustrative embodiments. A data packet is received at a switch. An identifier associated with the data packet is determined. The identifier corresponds to a logical partition in a logical partitioned data processing system. A lookup is performed in a data structure to determine a set of ports associated with the identifier. The set of ports is retrieved from the data structure. A port is selected from the set of ports and the data packet is transmitted from the port to the logical partition.

摘要： A method, medium and implementing processing system are provided for controlling the number of Ethernet adapters connected in an EtherChannel depending upon the current bandwidth requirements of the system. This system reduces power consumption, inter alia, wherever possible while not sacrificing performance or flexibility of an EthernetChannel. An exemplary embodiment EtherChannel's total bandwidth utilization is monitored and controlled. When the bandwidth utilization is a predetermined amount less than or more than a predetermined threshold level, power supplied to one or more of the physical Ethernet adapters that are part of the EtherChannel is adjusted, i.e. reduced or increased, accordingly. In another embodiment, in systems where ethernet devices support different levels of power, the power supplied to one or more adapters can be systematically incrementally reduced or increased in response to reduced or increased bandwidth utilization.

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 method and apparatus are provided for use with a SEA or other bridge device, which is positioned between virtual and physical LANS and is adapted to monitor connection setup packets. If the SEA detects such a packet, it determines whether it can accommodate the MSS value listed in the packet. In one embodiment, a method is provided for implementation by a bridge device positioned to transfer data packets between a specified LPAR system arid a specified host. The method comprises the step of detecting a packet that is transmitted to the bridge device, in order to set up a connection between the LPAR system and the host. The method further comprises determining whether the detected packet indicates an initial MSS value for the connection that is greater than a prespecified MSS value. Upon determining that the detected packet indicates an initial MSS value that exceeds the prespecified MSS value, the packet is altered to establish the prespecified MSS value as the MSS value for the connection.

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.
摘要翻译：提供了一种聚合TCP卸载适配器的系统，设备和方法。当数据在本地主机和远程主机之间进行交互时，与数据关联通常是本地端口和数据事务发生的远程端口。如果任何一个或两个主机具有多个TCP卸载的适配器，则可以通过向适配器分配公共IP地址来聚合适配器。然后选择一个适配器，根据本地端口和远程端口，数据事务将通过该适配器进行。具体地说，将两个TCP端口的端口号相加在一起并进行修改（即，经过模运算）和聚合中的适配器的数量。模运算的结果决定了哪个TCP卸载适配器用于处理数据事务。

摘要： Where parallel links between network devices are aggregated into link groups to support the transport of associated data streams, the link groups can be managed in an energy efficient manner by defining each link group as consisting of a primary link and one or more secondary links. The primary link in a link group remains enabled at all times but the secondary links are enabled only when needed and are disabled when no longer needed, minimizing power consumption for the secondary links (and the link group).

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.
