Alexander G. Fraser

Alexander " Sandy" G. Fraser (c. 1937) is a British- American computer scientist and research manager.

Fraser studied aeronautical engineering at the University of Bristol with a Bachelor 's degree in 1958, then worked at Ferranti to compilers and operating systems, and in 1969 received his doctorate at the University of Cambridge in computer science. He worked during this time for Ferranti at the computer lab at the University of the file system (file system ) and other system software of the prototype of the Atlas 2 (Titan ), the first time-sharing system in the UK, and was at Cambridge from 1966 to 1969 Deputy Director of Research. In 1969 he went to the Bell Laboratories, where he worked on cell - based data transmission networks ( DATAKIT Virtual Circuit Switch, Spider ring network), precursors of ATM virtual connections with. He also developed with SC Johnson techniques for optimizing instruction sets in computers, a trend that was later called RISC. He also developed the Unix Circuit Design Aids system was at Universal Receiver Protocol and involved in the development of cell-based home network INCON.

In 1982 he became head of the computer science research center (Computer Science Research Center) at Bell Labs, in 1987 and 1994 Executive Director Associate Vice President for computer science (information science research, the mathematics, signal processing, computer science and software included ). In 1996 he became Vice President for Research and founded ATT Laboratories, as ATT gave their fabrication at Lucent Technologies, and in 1998 he became chief scientist of ATT. In 2002, he went into retirement at ATT and founded Fraser Research.

He is a member of the National Academy of Engineering, Fellow of the British Computer Society (and their advice ) and IEEE Fellow.

In 1992 he was awarded the SIGCOMM Award for pioneering concepts such as Virtual (Virtual Circuit Switching), packet switching in spatial position (Space Division Packet Switching ) and data flow control windows ( Window Flow Control). In 2001 he received the Richard W. Hamming Medal for pioneering contributions to di architecture of communication networks with the technology of virtual circuit switching.
