Abstract
An information handling system includes a number of stations connected in a network configuration, each station including a processor, a storage and an I/O controller, where the processor operates under control of an operating system control program which is divided into a user (application) space and a kernel (system) space, the kernel may include a protocol layer interfacing the user application to a DLPI in the kernel, a DLPI which interfaces between the protocol module and a device driver interface, a device driver and a hardware device for connecting the station to the network. When data is to be received by a station from the network, the following steps are performed in the DLPI: recognize the network interface type (FDDI, Ethernet, Token Ring, etc.); recognize the protocol being used; format data according to the protocol; transmit to a Data Link Services user if address resolution is not required; if address resolution is required, test to determine if the protocol address resolution routine is registered; if registered, transmit data to the Data Link Services user; if not registered, call the default address resolution routine to resolve address and then transmit data to …
