Real-time communication is very important in the industrial control network, but a general SSLVPN is sometimes unable to meet this requirement perfectly. So a set of strategies are introduced to improve SSL protocol, on which a new parallel deploying 2-SSLVPN model is buit. This paper analyzes strategies and calculates the old and new models' time-consumption with the reference data. It has proved that the real-time improvement rate of the new model is 1.5 and its time-saving rate is 33%. It also introduces some future technical problems and their applications.
