OceanStore is a utility infrastructure designed to span the globe and provide
continuous access to persistent information. Since this infrastructure is
comprised of untrusted servers, data is protected through redundancy and
cryptographic techniques. To improve performance, data is allowed to be cached
anywhere, anytime. Additionally, monitoring of usage patterns allows adaptation
to regional outages and denial of service attacks; monitoring also enhances
performance through pro-active movement of data. A prototype implementation is
currently under development.
Our starting assumptions are: (i) a vast diversity of computing devices (PDAs,
cameras, displays, sensors, actuators, mobile robots, vehicles), (ii)
"unlimited" storage (servers supporting personal storage beyond a terabyte;
anything that can be captured and stored in digital form will be), (iii) every
computing device is connected roughly in proportion to its "capacity" (small
devices with little bandwidth, communicating locally to larger devices with
access to increased capacity), (iv) devices are predominantly "compatible,"
rather than predominantly incompatible (plug and play interoperation enabled by
perva-sive technology for on-the-fly translation, emulation, and virtual
machines). The only common element is communication. Devices will be so
specialized that it will be unusual to have one with an "average" amount of
processor, memory, disk, display, input, and connectivity.
