摘要： Byte utilization is improved in Remote Direct Memory Access (RDMA) communications by detecting a plurality of concurrent messages on a plurality of application sockets which are destined for the same application, client or computer, intercepting those messages and consolidating their payloads into larger payloads, and then transmitting those consolidated messages to the destination, thereby increasing the payload-to-overhead byte utilization of the RDMA transmissions. At the receiving end, multiplexing information is used to unpack the consolidated messages, and to put the original payloads into a plurality of messages which are then fed into the receiving sockets to the destination application, client or computer, thereby making the consolidation process transparent between the initiator and the target.
摘要翻译：在远程直接存储器访问（RDMA）通信中通过检测多个应用于相同应用，客户端或计算机的应用套接字上的多个并发消息，截取这些消息并将其有效载荷合并到较大的有效载荷中，从而改善了字节利用率，以及然后将这些合并消息发送到目的地，从而增加RDMA传输的有效载荷到开销字节的利用率。在接收端，多路复用信息用于解包合并消息，并将原始有效载荷放入多个消息中，然后将这些消息馈送到目的地应用程序，客户机或计算机，从而使合并过程在发起者和目标。

摘要： Provided are techniques for active SEA learning about a client LPAR MAC addresses via address resolution protocol (ARP) packets received on a virtual interface (of the active SEA). Any new client MAC addresses learned on the active SEA are sent to the inactive SEA via a control channel. When SEA failover happens, as the previously inactive SEA is about to become active, it will first send out RARP (reverse ARP) packets with the client MAC addresses as the source MAC addresses respectively. This effectively informs the switch connected to the previously inactive SEA that these client MAC addresses are to be routed through this switch port; the client MAC addresses saved on the switch connected to the previously active SEA are cleared as a result.
摘要翻译：提供了通过在活动SEA的虚拟接口上接收的地址解析协议（ARP）分组来主动SEA学习关于客户端LPAR MAC地址的技术。在活动SEA上学习的任何新的客户端MAC地址都通过控制通道发送到非活动的SEA。当SEA故障切换发生时，由于以前无效的SEA即将变为活动状态，因此首先会将客户端MAC地址分别作为源MAC地址发送出RARP（反向ARP）报文。这有效地通知连接到先前不活动的SEA的交换机，这些客户端MAC地址将通过该交换机端口路由; 因此，保存在连接到先前活动的SEA的交换机上的客户端MAC地址被清除。

摘要： Embodiments of the present invention provide methods, systems, and computer program products that enable secure network communications with logical partitions. A gateway between a physical network adapter and at least one virtual network trunk adapter receives a packet. The gateway tags the packet with an indication of an origin of the packet. The gateway delivers the tagged packet to an intrusion prevention system for intrusion analysis. When the gateway receives the tagged packet from the intrusion prevention system, the gateway forwards the tagged packet according to the indication of origin of the tagged packet.
