Abstract
DLL devices are built with multiple MAC address instead of a single MAC address, and provide a multiple virtual DLL interfaces to the upper layers (3-7) in a computer. This results in a new class of multi-function computers for attachment to a network system which take advantage of the multiple virtual DLL interfaces, to increase performance of the respective functions executed by the computer. Thus, a new network interface control apparatus and a new class of multi-function computer systems for attachments to networks are provided. The memory in the medium access control device stores a plurality of additional network addresses in addition to the assigned network addresses. The address filtering logic includes circuits responsive to the additional network addresses, such as logic for blocking a particular frame on at least one of the plurality of data channels when the source and destination address of a particular frame are found in the additional addresses stored in the memory. The plurality of data channels served by the media access control device may reside on a single physical interface, or in independent physical interfaces as suits the needs of a particular design. A high …
