Abstract
A reverse address resolution protocol for use in a communication network which allows resolution logic to provide a higher level protocol information (such as an IP address) to a source of a request for such information, independent of the physical network address of such source. The protocol is used in a processor having a plurality of ports, at least one of such ports connected by a point-to-point channel to a remote network device. Reverse address resolution protocol is responsive to a resolution request from the remote network device across the point-to-point channel to supply the higher level protocol information based upon the port through which the resolution request is received, rather than the physical network address of the requesting device. Thus, a remote device may be coupled to a network, and connected to a central management site across a point-to-point communication link, in a 'plug and play' mode. The person connecting the device to the remote network does not need to determine the physical network address of the device or configure the device with a higher level address protocol.
