MOSAIC: unified declarative platform for dynamic overlay composition

Overlay networks create new networking services across nodes that communicate using pre-existing networks. MOSAIC is a unified declarative platform for constructing new overlay networks from multiple existing overlays, each possessing a subset of the desired new network's characteristics. MOSAIC overlays are specified using Mozlog, a new declarative language for expressing overlay properties independently from their particular implementation or underlying network. This paper focuses on the runtime aspects of MOSAIC: composition and deployment of control and/or data plane functions of different overlay networks, dynamic compositions of overlay networks to meet changing application needs and network conditions, and seamless support for legacy applications. MOSAIC is validated experimentally using compositions specified in Mozlog: we combine an indirection overlay that supports mobility (i3), a resilient overlay (RON), and scalable lookups (Chord), to provide new overlay networks wi...
