Computer Communications Laboratory

/ Behcet Sarikaya / Professor
/ Senro Saito / Associate Professor

The Computer Communications laboratory is involved with education and research on all aspects of computer communications. Ongoing projects in education include an SCCP project on Social Hyper-networking and two topdown courseware design projects, one on High-speed Network Courseware Design for Synthetic Worlds and another on an authoring system called AuthCAL for topdown courseware development environments.

The social hyper-networking project aims at providing communication facilities such as electronic mail, voice mail, electronic conferencing, bulletin boards, real time talk and facsimiles. The AuthCAL project has the goal of providing an object-oriented graphical user interface and programming tools to make some teaching materials. The high-speed network courseware project aims at designing graduate and undergarduate level courses to teach the basics of high-speed networking.

In research, all aspects of computer networking are being investigated. However, present interest areas are concentrated on:

• Multimedia communication systems. Multimedia synchronization, application of protocol engineering techniques for multimedia system designs, verification and testing.
• Network management protocols. Network management using internet methodology, test design and implementation of network management systems, test design for the management information bases.
• Personal Communication Systems. Mobile and wireless networks; Multimedia for PCS; Protocols for mobile networks.
• Communication systems for virtual reality.
• Audio-visual network architecture. Cross analog and digital transmission network (CrossOver Net); audio-visual communication protocol modelling on the OSI reference model.

We are doing collaborative research with several Japanese and foreign universities and research centers. In Japan, our partner researchers work in Shizuoka, Tohoku and Osaka Universities and the Advanced Institute of Communications in Sendai. Overseas, we collaborate with Protocol Test Center in Montreal, Canada; Sherbrooke University in Sherbrooke, Canada, Omnipoint Corporation in Colorado Springs, U.S.A; Ege University in Izmir, Turkey; and GMD National Center for Information Technology in Darmstadt, Germany.

   New protocol stacks called CrossoverNet/G2 are used to construct beyond the next generation multimedia network. The protocol stacks offers two characteristic services, AV connections are able to transmit multimedia information consist of analog and digital media, and a network system is equipped communication service and broadcasing service. The project was proposed by The Univ. of Aizu, and promoted by IPA/MITI.
