Stability in a network of MONADS-PC computers

The MONADS-PC computer system implements an architecture supporting a very large persistent store based on a uniform virtual memory. We have previously shown how this virtual memory scheme can be extended to encompass a local area network of MONADS-PC computers. In this paper we examine the question of the integrity of the store in such a network. A modification to the MONADS architecture to implement stability is reviewed and extended to guarantee stability of a network-wide persistent store. The stability scheme allows for temporary interruption to the physical network without affecting the validity of exported pages owned by a node.
