E-Cast: Elastic Multicast
Philipp Unterbrunner, Gustavo Alonso, and Donald Kossmann
January 2011
This technical report describes E-Cast: a uniform causal-total-order multicast protocol designed to implement fault tolerant, highly elastic, yet strongly consistent database engines in the cloud. In contrast to traditional group communication, the model underlying E-Cast defines multicast as a stateful routing problem. In this document, we provide a rigorous formalization of the routing problem, show how partial replication with strong consistency guarantees can be reduced to said routing problem, and present its efficient algorithmic solution, E-Cast.
