Abstract:

As computing systems continue to expand in size in the Internet environment, the reliability of the distributed stream architecture is facing serious challenges. Based on the Nmodular redundancy technique, we propose a triple modular eager redundancy faulttolerant method for the distributed stream architecture (TREFT). The TREFT employs three program copies to run the error detection and error correction processes efficiently. Experimental results on a prototype system of the distributed stream architecture show that the TREFT could enhance the reliability of the system at very low cost, increasing the faulttolerant cost by 10.77% on average.

Key words: distributed stream architecture;faulttolerant technique;triple modular redundancy
