Replication has become a central element in modem information systems playing a dual role: increase availability and enhance scalability. Unfortunately, most existing protocols increase availability at the cost of scalability; This paper presents architecture, implementation and performance of a middleware based replication tool that provides both availability and better scalability than existing systems. Main characteristics are the usage of specialized broadcast primitives and efficient data propagation.

This paper deals with scalable switching fabrics for high-performance routers with large numbers of ports for connecting external links operating at various speeds to arrive at aggregate rates up to multi-terabits per second. The proposed switching fabrics employ no centralized scheduling and consist of small routing units (RUs), which are interconnected by multistage-based connecting components (CCs) in accordance with grid structures, with routing decisions made by RUs and CCs individually in a simple, distributed manner. They are referred to as grid-oriented, multistage-connected RUs, dubbed GRM. With distributed routing, GMR enjoys good scalability and low hardware complexity. It is found, based on our extensive simulation, that GMR outperforms not only their crossbar counterparts for small sizes, but also their compatible designs aiming at large sized construction (built from multiple stages of small crossbars), despite its lower hardware complexity. Two types of chips are sufficient to permit any sized construction; one for RUs and another for CCs. The proposed switching fabrics are cost-effective, readily suitable for scalable routers.
