摘要： The invention ensures that a single and consistent reply is made to an ARP request in a system of connected IP networks. When an adapter becomes active, the relative network on which it resides is determined by transmitting control packets over it and all other adapters known to the host and observing if and where responses are returned to the adapters. One adapter on a network is designated as active. If the same network contains other adapters, they are marked as standby adapters for the purpose of responding to ARP messages. Special processing is provided for offload adapters that perform there own ARP processing.
摘要翻译：本发明确保在连接的IP网络的系统中对ARP请求进行单一一致的回复。当适配器变为活动状态时，通过在其上传输控制数据包以及主机已知的所有其他适配器并观察响应是否返回到适配器，确定其驻留的相对网络。网络上的一个适配器被指定为活动的。如果同一个网络包含其他适配器，则它们被标记为备用适配器，以响应ARP消息。为执行自己的ARP处理的卸载适配器提供特殊处理。

摘要： The invention ensures that a single and consistent reply is made to ARP request in a system of connected IP networks. In each host, the first adapter A to become active is designated as being in an arbitrary first physical network (PNET1). For each subsequent adapter B to become active on a host, the host sends a packet over one of the adapters (A) of each network already known to the host with a hop count of one. If the packet is received over adapter B, it is known that adapters A and B are in the same physical network. If this occurs, adapter B is marked as being in the same network PNET1 as adapter A. If the packet is not received over adapter B then B is in a different physical network as A. In this event, adapter B is marked as being in a new network PNET2. When adapter A becomes inactive, if there are other active adapters in the physical network to which A belongs, then one of the remaining adapters B in that physical network is designated to have the responsibility for replying to ARP requests for A. A gratuitous ARP advertisement is transmitted into the network mapping IP-A with MAC-B. When adapter A again becomes active, adapter A will re-assume ownership of ARP replies for IP address A.
摘要翻译：本发明确保在连接的IP网络的系统中对ARP请求进行单一一致的回复。在每个主机中，要变为活动的第一适配器A被指定为在任意的第一物理网络（PNET1）中。对于每个随后的适配器B在主机上变为活动状态，主机通过跳数为1的主机已知的每个网络的一个适配器（A）发送分组。如果通过适配器B接收到分组，则知道适配器A和B处于相同的物理网络中。如果发生这种情况，则适配器B被标记为与适配器A在同一个网络PNET1中。如果未通过适配器B接收到分组，则B与A处于不同的物理网络。在这种情况下，适配器B被标记为处于一个新的网络PNET2。当适配器A变为非活动状态时，如果物理网络中存在其他活动适配器，则该物理网络中剩余的适配器B之一被指定为对A的ARP请求进行回复的责任。无偿ARP广播被传送到MAC-B映射IP-A的网络中。当适配器A再次变为活动时，适配器A将重新承担IP地址A的ARP应答的所有权。

摘要： A system and computer program product for managing at least two physical links. A TCP/IP stack configures a first interface with attributes. The TCP/IP stack activates the first interface. The TCP/IP stack detects a channel path identifier (CHPID). The TCP/IP stack creates a second interface. The TCP/IP stack associates the second interface with the first interface. The first interface and the second interface are logically linked to exchange traffic corresponding to a single internet protocol address. The TCP/IP stack configures the second interface with at least one attribute. The TCP/IP stack activates the second interface. The two physical links may rely on two different physical link types.

摘要： A current value of a changing operating-system-level condition can be determined, wherein the operating-system level condition is a condition of a host related to an operating system resource utilization or an operating system experienced latency. The operating-system level condition can be a condition of a layer of the OSI model above the Data Link Layer. An inbound blocking factor algorithm can execute that uses the determined current value as a variable. A value for an inbound blocking factor can be generated as a result of executing the inbound blocking factor algorithm. The generated value can be utilized as the inbound blocking factor to determine a manner in which incoming messages are to be conveyed from a network adaptor, through an adaptor interface boundary, to an operating system of the host.

摘要： A method and system are disclosed for network adaptor optimization and interrupt reduction. The method may generate an immediate I/O interrupt notification to a host device driver in response to receiving data from a network. The method may also update an inbound buffer list based on the received data in the inbound buffer queue. Furthermore, the method may set the buffer state from an empty state to a primed state to indicate that the received data is available for processing. The method may also build an outbound buffer list based on outgoing data and add the outgoing data to an outbound buffer queue. Furthermore, the method may set a buffer state from an empty state to a primed state to indicate that the outgoing data is prepared for transmitting and signal a network adaptor with a notification signal.
