摘要： A multicasting apparatus that broadcasts messages to at least some of the clients in a computing network environment having a plurality of clients and at least one host connected to these clients via a gateway device. A multicast routing table is created for registering any host and clients requesting registration. The table will include one entry per host/client and includes their relevant information. A connectivity platform is used for controlling all communications so that all information packets is first received by the platform. Upon the receipt of a packet, the table is searched and if an match is found the packet will be routed using the entry information; otherwise, the packet will be dropped.

摘要： A computer program product for use with a computer system having a host and a plurality of clients coupled to one another via a local area network (LAN), to provide a multicasting of messages using a special command set. First computer readable code means is generated for issuing a first special command to add a new IP multicast address providing a group multicast address and an IP multicast address. Then computer readable code means is created for entering said special control command in a multicast routing table, one entry per connection request received. Computer readable code means is then provided for a use count mechanism for keeping track of numbers of communication stacks which have registered with a certain IP multicast address. Also computer readable code means is generated for comparing all inbound IP packets destined for an IP multicast address with said entries in said table and routing all matches to their appropriate communication stacks.

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： A method of multicasting messages in a computing network environment having at least one host and a plurality of clients connected and in processing communication with one another via a gateway device. Host(s) and client(s) requesting registration will be registered and their information will be entered in a routing table, one entry dedicated to each host or client. A connectivity platform controls all communication between the host and the client(s) by receiving all information packets. The Routing table is then searched and the packets are distributed accordingly to their owner once a matching entry is found. If a matching entry is not found the packet will be dropped.
