Abstract
Abstract This is a method and system of communicating on a data and computer communications network. The method of communications for a data and computer communications network, wherein the network includes a master system board with a plurality of subsystem boards, may comprise: transmitting informational packets to a network node from a first serial communications device through a serial communications bus, wherein the first serial communications device resides on a first subsystem board of the plurality of subsystem boards; receiving informational packets to the network node from the first serial communications through the serial communications bus; transmitting and receiving informational packets from the first serial communications device to a second serial communications device through a first parallel communications bus; and transmitting and receiving informational packets from the first serial communications device to a third serial communications device on a second subsystem board of the plurality of subsystem boards through a second parallel communications bus. The system includes a serial communications device for use in the data and computer communications network, wherein the device may have a transmitter with a memory buffer, a first medium access controller, a receiver with a memory and second medium access controller. The system may also include a parallel communications device with a communications interface and a memory on one subsystem board that communicates to other subsystem boards. The system may also include a router.
