Experience and Results from the Implementation of an ATM Socket Family

This paper describes the implementation of an ATM protocol stack as a protocol family within a 4.3 BSD derived Unix. A novel approach to the implementation of the management and control functions for the ATM protocol stack has been adopted. The data path is implemented within the kernel but all control and management functions are implemented by a user space daemon. An encapsulation of IP on the ATM protocol is provided by means of a logical IP interface. The mapping of IP addresses to ATM addresses is performed by the user space daemon.
