  • Multicast-enhanced update propagation in a weakly-consistant, replicated data storage system
    Patent number: 6557111
    Abstract: Epidemic-style update communications facilities are used in conjunction with multicast update communications facilities in weakly-consistent, replicated data storage systems. Epidemic-style communications handle a wide variety of failures at multiple levels of the system using a single, very robust, but also relatively high-latency mechanism. Multicast communication offers much quicker propagation but less fault tolerance using a different mechanism. The epidemic-style communications and multicast communications, combined for use in weakly consistent replicated database systems obtain a design that offers the benefits of both individual approaches.
