Why do you have to read our BA • We propose a new failure detector for the general omission model: • send / receive • permanent / transient • non selective / selective • Assumptions: • partially synchronous distributed system • reliable communication • majority of correct processes • Communication-efficient implementation: • at most 2(n-1) links are used forever • spanning tree among well-connected processes PODC’2010 − Zurich, Switzerland, July 25-28, 2010
Communication Efficiency BFS spanning tree n = 7 10 links are used (forever) PODC’2010 − Zurich, Switzerland, July 25-28, 2010
