Communication between multiple partitions employing host-network interface
TLDR
In this paper, a host-network interface is established for reducing network overhead at the multiple partitions in a mainframe class data processing system, which includes an address resolution protocol (ARP) cache designed to hold predetermined media headers for the clients coupled to the network(s).Abstract:
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. 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.read more

Internet protocol (IP) work group routing
TL;DR: In this paper, the authors propose an approach where multiple router interfaces are assigned the same IP network address, creating an IP work group, which enhances host mobility by allowing a host to be relocated anywhere in the work group without requiring reconfiguration of the host.

Methods and systems for interprocess communication and inter-network data transfer
Srinivasan Keshav,Rosen Sharma +1 more
TL;DR: In this paper, connectionless-oriented server and client programs operating on processing systems were modified to communicate with a connection manager to establish a virtual circuit before initiating communications with the connection-oriented routines, and encapsulators and decapsulators were used to enable communication programs to transfer data packets in a first format on an established virtual circuit over a network transmitting data in a second format.

Data packet header compression for unidirectional transmission
TL;DR: In this paper, a broadcast transmission system transmits data packets from a server to a client over a unidirectional broadcast network, where the server compresses the data packets by compressing the packet header.

VLAN frame format
TL;DR: In this paper, the authors proposed a method of identifying the virtual network associated with each data frame received by the network switch when transmitting the data frames over the shared communications medium, which can be used to determine whether to forward data frames accordingly.
