Notice: I left INRIA and moved to Keio University. My new home page is this one.

Research Topics:

Internet routing protocols and their working environments, especially IP multicast routing architecture and the deployment including implementations of IP multicast capable kernel and user code, are my research topics.
Designing of effective satellite communication architecture with bi-directional emulation, in order to make it one of major Internet infrastructures, is also my research target.
My research on wireless ad-hoc networking is about group communication and a practical self-organized secure mechanism.
Standardization of Internet Protocol with participating in several IETF WGs discussions is important to my research part.

Software Contributions:

IGMPv3 kernel and command implementation for NetBSD-current (04/May/2004): Introduction and source
MLDv2 kernel and command implementation for NetBSD-current (04/May/2004): Introduction and source
Patch for ethereal-0.9.11 to decode MLDv2 report
