Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose Hybrid IP-VPN architecture of mixed star and mesh topology. With this architecture, traffic between end-hosts does not go through IPsecGW, which enables IPsecGW's load reduction. Also, with this architecture, connecting new IP-VPN sites does not request changes of settings to connected sites, which was a problem of former mesh topology.
