This article explores the key technologies—high-pergormance,real-time multimedia information transmission algorithm about the modern long-distance teaching system,and further propose a method about accessing to screen information based on mirror display driver.

In this article,a IPSec VPN system based on virtual adapter is suggested and implemented.

Research of SSL VPN architecture based on virtual network interface card;

The paper discusses how to transform a wireless network into an IP-based network,and introduces the key technologies such as the virtual network interface card designing and the RIP routing algorithm implementation.

A fault tolerant and load balance technology based on virtual NIC for redundancy network;

An IPSec VPN architecture based on intercepting packet mechanism by virtual network adapter is presented, and then the packet can be enveloped by IPSec in user model.

In order to solve the software conflict of traditional client mode SSL VPN system,which is caused by the adopted package interception technology of NDIS intermediate driver,this paper proposes an advanced SSL VPN system architecture based on virtual network adapter.

This paper introduces a 3D spatial searching system that can virtual display going course in VC++6.

The design and fabrication of large-scale two-dimensional display screen of light-emitting diodes(LEDs )is described along with their implementation as image sources for prototype virtual displays.
