A system for and method of rapidly streaming data to one or more client devices, such as personal computers (PC's) from a server employing virtual disk emulation and broadcasting or multicasting of data residing on a network server. In some embodiments, the streamed data includes files necessary to boot and configure the one or more client devices, the data including hibernation, O/S and application files.

Improved method of encoding and repairing data for reliable storage and transmission using erasure codes, which is efficient enough for implementation in software as well as hardware. A systematic linear coding matrix over GF(2) is used which combines parity for fast correction of single erasures with the capability of correcting k erasures. Finite field operations involving the coding and repair matrices are redefined to consist of bitwise XOR operations on words of arbitrary length. The elements of the matrix are selected to reduce the number of XOR operations needed and buffers are aligned for optimal processor cache efficiency. Decode latency is reduced by pre-calculating repair matrices, storing them in a hashed table and looking them up using a bit mask identifying the erasures to be repaired.
