Abstract

This report describes extensions to the Communications Subsystem of the Amadeus Kernel developed at Trinity College Dublin.

In the Amadeus system, the CS provides the communication services necessary to carry out all remote operations. Inter-kernel communication in Amadeus is accomplished through message passing between corresponding kernel components of distinct kernels. The Inter-Kernel Message protocol is a lightweight message transaction protocol, which provides the necessary support for reliable communication between kernels.

Currently, the IKM has been implemented above UDP/IP on Digital Equipment Corporation's Ultrix 4.2 and Sun Microsystem's Sun0S, on MicroVAXes, DECstations, and SPARCstations.
