Research for STDM Based SSL VPN
Aiming at the defects of the ordinary SSL VPN that the frequent setting-ups of tunnels will consume a large number of system resources,this paper presented a mechanism called STDM(Secure Tunnel Division Multiplexing).The kernel of this mechanism was Tunnel Caching,which implemented the shared use of secure tunnels by the independence of tunnel of a remote service.This mechanism would improve the efficiency of the system.
