    • A method in a computing network environment for host partition computers to share a multicast communication adapter connected to a local area network. Each host partition sends information identifying the host application as well as a multicast addressing protocol to the shared multicast communication adapter. The communication adapter registers the information and directs inbound multicast packets from the LAN to the appropriate host partition application. In a preferred embodiment, the communication adapter registers the information according to the IP multicast address. In a preferred embodiment, a counter is employed in the communication adapter to maintain a count of the number of host applications that are registered. The invention further provides a method for un-registering a host partition application.
    • 用于主机分区计算机的计算网络环境中共享连接到局域网的多播通信适配器的方法。 每个主机分区向共享的多播通信适配器发送标识主机应用的信息以及组播寻址协议。 通信适配器注册信息,并将来自LAN的入站组播数据包引导到相应的主机分区应用程序。 在优选实施例中,通信适配器根据IP多播地址登记该信息。 在优选实施例中,在通信适配器中采用计数器来维护登记的主机应用的数量的计数。 本发明还提供了一种用于取消注册主机分区应用程序的方法。

    • In a computing network system environment having a gateway device that is electronically connected from one side to a plurality of initiating hosts and on another side to at least one local area network, in turn connecting a plurality of hosts are connected to the gateway device, a method and apparatus for eliminating any need for building a separate and special protocol data unit element for each header. The computer network environment uses a Multi-path channel communication protocol as well as protocol data units to point to various portions of data. An interface layer is provided between a plurality of protocol stacks and the multi-path channel protocol. The interface layer has a timer which will wait for data from the protocol stack. A list of all buffers are assembled as received comprising of one entry for each data buffer. This buffer list is then transferred to the multi-path channel protocol layer upon expiration of the timer, which is in turn sent to any channel attached processor as one block. A deblocker interface is also provided on all channel attached processors so that any length fields provided in the protocol headers can be used to determine offset of next data element in said block and thus eliminating need for a special header at next data element used by the communication protocol.
    • 在具有网络设备的计算网络系统环境中,网关设备从一侧电连接到多个发起主机,另一方面连接到至少一个局域网,依次连接多个主机连接到网关设备, 方法和装置,用于消除为每个报头构建独立和特殊的协议数据单元元素的任何需要。 计算机网络环境使用多路径信道通信协议以及协议数据单元来指向数据的各个部分。 在多个协议栈和多路径信道协议之间提供接口层。 接口层有一个定时器,它将等待来自协议栈的数据。 所有缓冲器的列表被组合成接收,包括每个数据缓冲器的一个条目。 然后,在定时器到期时,该缓冲器列表被传送到多路径信道协议层,定时器依次发送到任何通道连接的处理器作为一个块。 在所有通道连接的处理器上还提供解块器接口,使得在协议报头中提供的任何长度字段可用于确定所述块中的下一个数据元素的偏移量,从而消除了对通信使用的下一个数据元素的特殊报头的需要 协议。
