H.323 Based Collaborative Environment for High Energy and Nuclear Physics

After having evaluated various H.323 products for these two years,KEK and Japanese HENP community started to move from ISDN(H.320)-based video conferencing environment into IP(H.323)-based one.Primary reason for the move is to cut down the ever increasing ISDN communication cost.At the same time the H.323 can offer us more powerful collaborative environment.In order to make KEK to be a center for the H.323-based collaborative environment in Japan,Picture Tel‘s LIVE GATEWAY as a H.320/H.323 gateway ,which is essential for the smooth transition,Cisco IP/VA 3510 as a H.323/MCU,and Cisco 2610 as a gatekeeper were installed at KEK in March 2001,And the transition started.In this paper,we‘ll describe the collaborative environment which our users can have,together with its operational results.
