Abstract:This paper has produced one kind the EduMAN pattern which constructs based on the VPN technology, after the research of EduMAN the characteristic ,.In the article starts from the VPN technology analysis, summarizes VPN in the net area deployment way, and has
produced the recommendation deployment model in the VPN EduMAN. In addition the RBAC
has also been introduced in the VPN EduMAN, proposed the maintenance of role incompatible and the smallest jurisdiction means, and the realization means has also been given.
