Some bus protocols are useful for management of peripheral devices that exist on a computer's system bus. Such bus protocols include the industry standard architecture bus (ISA), peripheral component interconnect (PCI), PCI express (PCIe), etc. The usefulness of such protocols for control messages, interrupt management and more is limited to the short distances over which the protocols operate, usually measured in inches. The use of longer distance transport protocols, such as Ethernet to encapsulate and transport bus protocol messages allows the advantages of the short distant protocols to be used to control remote devices. A master device, with a controller or processor, may be used to manage the operation of a slave device using the bus or control protocol. Such management may include button presses, indicator lights, slave device configuration, etc. The slave device may have a low cost controller or ASIC to provide real-time operational functions, such as routing.
