Research Pursuits 【 display / non-display 】

  • Recently, advanced network computing systems have been realized as various sorts of computers and resources are connected with each other, owing to prosperity of large-scale networks represented by Internet. In our laboratory, several innovative methods are proposed for such an environment in order to make the best use of computer resources comfortably and securely. They include IP-SAN Consolidated PC Cluster, High Performance Dependable SAN over Virtual Private Network (VPN), Authentication and Cryptography on Wireless LAN, and TCP Parameter Analysis and Control. Network protocols and concept models suitable for each environment are proposed.
