Synchronous atomic broadcast for redundant broadcast channels
Abstract
We propose a synchronous atomic broadcast protocol for distributed real-time systems based on redundant broadcast channels. The protocol can tolerate a finite number f of concurrent processor crash failures, channel adapter performance failures and channel omission failures. Its message cost is optimal: when no failures occur only f+1 messages are sent per broadcast. The cost implications of providing tolerance to other failure classes are also investigated. © 1990 Kluwer Academic Publishers.
