SUMMARY:Designing an Optical Internet Router with a Preview of an Optical 
 Turing Machine for Network Processing - Joe Touch (USC/ISI)

CONTACT:Professor Andrew W. Moore
DESCRIPTION:This talk presents a design for an optical router based on dec
 omposing the steps required for IP packet forwarding. Previous implementat
 ions of hopcount decrement and header matching are integrated with a recen
 t simulation-based approach to variable-length packet merging that avoids 
 recirculation\, resulting in an all-optical data plane. A method for IPv4 
 checksum computation is introduced\, and the implications of this design a
 re considered\, including the potential for chip and system integration. T
 hese components are extended from binary to higher-density (multiple bits 
 per symbol) encodings\, which led to our new Optical Turing Machine (OTM) 
 project. OTM explores the unification of communication and computation thr
 ough a new approach to digital optics to enable network processing of a hi
 gh-density modulation format capable of high-speed\, long-distance transmi
 ssion.\n\nBio: Joe Touch is the Postel Center Director in USC's Informatio
 n Sciences Institute and a Research Associate Professor in USC's Computer 
 Science and EE/Systems Departments. He received his Ph.D. from the Univ. o
 f Pennsylvania and joined ISI in 1992\, and his current projects involve v
 irtual networks\, optical Internets and computation\, and network security
 . Joe is in Sigma Xi\, an ACM Distinguished Scientist\, and an IEEE Senior
  Member and ComSoc Distinguished Lecturer. He serves on various committees
  and the editorial boards of IEEE Network and Elsevier's Journal of Comput
 er and Systems Sciences\, and is active in the IETF.\n
