Computer network interface for direct mapping of data transferred between applications on different host computers from virtual addresses to physical memory addresses application data

摘要

A computer interface system for communicating between computers along designated circuits is provided. An interface unit is provided in each host computer. Each unit includes a memory map that stores a map of physical addresses that correspond to virtual addresses for each application involved in a communication link. Each transfer of data is designated by a circuit that is established using the ATM protocol. The circuit is recognized by each unit involved in the communication and facilitates direct access of each host computer's main memory with minimum intervention from the operating system. A novel dynamic buffer management system is also provided.
