With the development of 64-bit microprocessors, a global virtual memory (GVM) system running on workstations is proposed to construct a system in which all objects reside in one address space. Most current distributed operating system are based on remote procedure call to access the objects at other node. This type of node to node communication style is inappropriate in GVM system. This algorithm is slow, inefficient and wastes network bandwidth. A low cost local area network, AMNET - A Multi-Media Network is proposed to be used to connect the workstations in GVA system. This network has the advantages of high speed, low cost, supporting point to multi-point communication, real-time data transfer independent of host which allows the AMNET to be a good choice of LAN to connect workstations for GVM operating system. The network interface equipment connecting the workstations in GVM distributed operating system on AMNET is studied, developed, and discussed in this project. The network interface equipment in each node consists of a communication processor and a service adaptor. The communication processor provides services to handle page requests from the host and from the network. It is further developed to handle page request for read only (R/O) and writable page, page ownership transfer, R/0 page invalidation. It is also further enhanced as the pre-fetched R/O page cache buffer for the host. The service adaptor is the passive devices responsible for high speed page data transfer between nodes. A very reliable transport protocol with large sliding window size is proposed here. This transport protocol has the advantage of taking care of any message loss and minimizing the acknowledgement message returned to the sender. The network interface equipment is verified with software simulation. So far the result is proven working with satisfaction under normal and any message loss condition. The transport protocol for transferring page data is also proven totally reliable and working properly under any situation.","abstract_html":"Workstations are widely used in the scientific and engineering community connected together with local area network (LAN) so as to make convenience to program in one node to access the information at the others.
