Abstract
An interface system for transferring information between a local area network and a system memory associated with a station attached to the network. The interface system includes a bus interface unit for implementing the transfer of information between the interface system and the memory system. An indicate module transfers information received by the interface system from the network to the memory system via the bus interface unit. A request module transfers information received by the interface system from the memory system via the bus interface unit to the network. A status generation/space management module connected to the indicate module and to the request module monitors the status thereof and generates corresponding status signals and manages the allocation of storage space in the memory system for information transferred between the network and the memory system via the interface system.
