摘要： In a mainframe class data processing system having multiple logical partitions and a port to a network, a host-network interface is established for reducing network overhead at the multiple partitions. The host-network interface includes, for example, a host channel connection coupling the multiple partitions of the host system to a communications adapter having a network device driver for each network coupled to the adapter. The adapter also includes an address resolution protocol (ARP) cache designed to hold predetermined media headers for the clients coupled to the network(s) for use in forwarding an internet protocol (IP) datagram across the network to one of the clients from a partition of the host system. If not predetermined, the adapter is provided with a capability to dynamically determine the needed media header for transmission of the IP datagram across the network to the client. In Ethernet format, this dynamically determining includes forwarding an Ethernet 802.3 ARP request and an Ethernet DIX ARP request from the IP datagram. Provision is also made for partition-to-partition communication of IP datagrams by storing IP addresses of the logical partitions as HOME addresses in the ARP cache of the adapter.

摘要： A method of allowing any initiating host to establish communications with any receiving host in a computing network using a Multi-path channel communication protocol. The computing environment also having a gateway device that is electronically connected from one end to at least one initiating host and at the other end to at least one local area network through which a plurality of hosts are connected to the gateway device. The method comprise the steps of first performing an initialization step during information and addresses of all present hosts are determined and stored in a port-sharing table which is kept up to date by regular monitoring of availability status. All host communications is performed entirely through the gateway device. Upon the receipt of a special IP address certain information is obtained from the datagram. Then the address and information of the initiating host is compared to the entries in the portsharing table and if no match is found a new entry is made. All necessary information for the establishment of a successful communication between the two hosts are then provided to the initiating host.

摘要： A method of dynamically providing a host information about all functions supported by a communication platform provided in a computing network environment is presented. The computing network environment is also provided with a gateway device that is electronically connected at least to one initiating host and at least one receiving host, besides the associated communication platform. During an initialization step all functions commercially available on all communication platforms are inputted in a special function table. Then the particular associated platform is queried and the functions provided in the computing environment is determined and inputted also in the function table. All alterations and modifications to the availability of old functions or addition of new functions are also monitored and inputted in the table. In this manner any host connected to the gateway device can obtain a list of all available functions supported by the communication platform at any one time and if desired, even any such host can chose a function from this list of available functions.

摘要： Data received over a shared network interface is directly placed by the shared network interface in a designated memory area of a host. In providing this direct memory access, the incoming data packets are split, such that the headers are separated from the data. The headers are placed in a designated area of a memory buffer of the host. Additionally, the data is stored in contiguous locations within the buffer. This receive and store is performed without interruption to the host. Then, at a defined time, the host is interrupted to indicate the receipt and direct storage of the data.

摘要： A network virtualization layer for an information handling system in which a physical machine coupled to a network is divided into a plurality of logical partitions, each of which has a host system residing thereon. In response to receiving a set command from one of the host systems specifying a data link layer (layer 2) address, the virtualization layer associates the data link layer address with the host system and forwards to the host system data packets specifying the data link layer address as a destination address. Unicast packets are forwarded to the single host system specifying the destination address as an individual MAC address, while multicast packets are forwarded to each host system specifying the destination address as a group MAC address. A host system may also specify a virtual LAN (VLAN) ID, which is used to scope the forwarding of packets to host systems sharing that VLAN ID.
