Contemporary distributed office systems rely heavily on communication between workstations, file servers, printers, and other computerized components. The COSIE Communication Subsystem has been developed for an office system internetwork consisting of local networks of varying technologies. The communication facilities provide for the transmission of self-contained messages to mailboxes, which are referenced by capabilities and may be shared. A generalized method for pairing requests with responses supports a variety of communication paradigms, while a flexible routing algorithm permits diverse network topologies. The main emphasis in the design of the COSIE Communication Subsystem was on presenting simple mechanisms that allow more general policies and protocols to be explored.

“…As is our usual practice in such situations, we prefer to adopt a form of network specific fragmentation: let the driver at the entry gateway fragment the internet packet in an appropriate manner, and have the fragments reassembled at the exit gateway, before the packet is routed to its next destination [Shoch, 1979: Boggs, et aL, 1979. This means that the gateway program itself need not know anything about the fragmentation, but that the fragments must all arrive at the Radionet driver in the same exit gateway for reassembly.…”

The Bay Area Packet Radio Network has been integrated into an existing architecture for network interconnection: it can be used to provide radio communications for directly connected hosts, or as an alternative packet transport mechanism to carry traffic between two local networks.The radio link is operational, and can support regular internetwork communications at rates ranging from 12 to 20 kilobits/second, with the current Packet Radio equipment.Use of the Radionet required only the writing of a network specific driver for the standard communications software package. The driver is responsible for controlling the interface to the Radionet, performing fragmentation and reassembly of large packets, routing within the Radionet, and similar tasks.
