Abstract: Efficient load balancing is essential for parallel distributed computing. Many parallel computing environments use {\tt TCP} or {\tt UDP} through the socket interface as a communication mechanism. This paper presents the design and development of a prototype implementation of a network interface that can preserve communication between processes during process migration. This new communication library is a substitution for the well-known socket interface. It is implemented in user -- space; it is portable, and no modifications of user applications are required. {\tt TCP/IP} is applied for internal communication, which guarantees relatively high performance and portability.

Keywords: distributed computing, load balancing, process migration, {\tt Dynamite}, sockets
