Description:
Programmers of reliable large-scale distributed systems need tools to simplify tasks such as replicating services or data. Group communication systems achieve this via various flavors of reliable multicast, but the existing solutions do not scale in all major dimensions. Typically, they scale poorly in the number of groups; yet we believe that using groups casually, to represent individual objects or services, could lead to new, easier ways of programming. We propose QuickSilver Scalable Multicast (QSM), a new multicast substrate that scales in several dimensions at once. Our approach relies on a novel way of exploiting the overlap between groups. This is joint work with Professor Ken Birman.
