Prof. Hiroshi Esaki , WIDE Project, Japan

  He has started the research and development for data communication system, since he has jointed to the R&D Center of Toshiba Corporation in 1987.   For three years, he has researched on the flow control architecture and algorithm for ATM networks, especially on Connection Admission Control. 

  From 1990 to 1991, he has been at Applied Research Laboratory of Bellcore Inc., New Jersey (USA), as a residential researcher.  During his staying at Bellcore Inc., he has researched on high speed internet architecture.   Especially, he has researched on IP packet routing algorithm for ATM and other high speed datalink technologies. 

  He has researched on IP packets forwarding architecture over the ATM networks, after his staying Bellcore Inc.  The basic architecture of CSR (Cell Switch Router) has been explored during this research activity. 

  From 1994 to 1996, he has been at CTR (Center for Telecommunication Research) of Columbia University in New York (USA).  During his staying at Columbia University, he has proposed the CSR architecture to the IETF and to the ATM Forum.  He has held the colip-bof (i.e., connection oriented and connectionless IP BoF) session with Dr.Masataka Ohta of Tokyo Institute Technology, at IETF meeting held in April 1995.   As well as research on CSR, he has researched on the mobile computing architecture and on the large scale reliable multicast architecture.   Regarding the large scale reliable multicast, he has proposed the ATM-level FEC (Forward Error Correction) scheme (i.e., FEC-SSCS) to the ATM Forum with Aloke Guha (Network System Corp), George Carle (Karlshe University) and with Tim Dwight (MCI).  He had three BoF sessions on FEC-SSCS at the ATM Forum.

  After the staying at Columbia University, he has conducted the CSR implementation team in Japan to initiate the CSR project in Toshiba.  He works as a chief architect of CSR project in Toshiba Corporation.  He is actively work at IETF, representing Toshiba Corporation and sometimes representing WIDE project.  Also, he is the principle person for collaboration with the key engineers and architects of cisco systems (e.g., Dr.Yakov Rehkter).   The initial project team on CSR at R&D center leaded by him was six researchers.   According to the initiation of CSR project in Toshiba, product development division has involved into the project.  After the project was initiated, his mission on CSR project are as followed;

  1. Consultation and management of research direction for CSR team in R&D center
  2. Management of CSR system development in Toshiba
  3. Marketing of CSR system
  4. Standardization activities, representing Toshiba, to the IETF
  5. Collaboration arrangement and technological discussion with cisco systems

  He is also very active at WIDE project.  He has initiated the LAST (Label Switch Technology) working group and the large scale reliable multicast architecture study, in WIDE project.  He is also deeply involving the designing and the initiating the trial networks regarding future label switch router and IPv6 networks.  

  He was an NOC(Network Operation Center) member of Networld+Interop 97 Tokyo, and will be an NOC member of Netwold+Interop 98 Tokyo.

  From 1997, he has involved in the IPv6 research and development at the WIDE project. He is a founder of series of IPv6 special project in the WIDE project, i.e.,

   (1) KAME project ; IPv6 protocol stack for BSD UNIX
   (2) TAHI project ; IPv6 test and evaluation specification and tools
   (3) USAGI project ; IPv6 protocol stack for Linux

  Regarding the research/development/deployment for the IPv6, he has been very tightly and closely working with Prof. Jun Murai, who is a political and technical advisor for the Japanese cabinet.   He is an executive director of IPv6 promotion council, which is cross ministry and cross industry council to promote the IPv6 technology.

  After he got Ph.D from University of Tokyo in 1998, he has jointed to the ComputerCenter for the University of Tokyo, as an associated professor.   From April of 2000, he is an associated professor of the Graduate School of Information Science and Technology at the University of Tokyo.
