distributed hash table based design of soft system buses
Large scale computing systems which can run for unlimited time and can evolve over time have a growing demand in this modern information society. Soft System Buses (SSBs) were proposed to provide middleware platform support to such computing systems. This paper proposes a design of SSBs based on Chord -- a distributed hash table protocol for large scale peer to peer systems. Our design fulfills the requirements of SSBs like scalability, automatic recovery from failures, data preservation and incremental runtime upgradeability and maintainability. An assessment of our design from the view point of the requirements of SSBs is also presented.
