The Tunnel Network Monitoring Technology To Achieve The Ipv6 Protocol

As a common Internet user of China, you may be under the press of IP address-scarcity. Several computers connect to internet through only one unicast IP address with NAT. Server needs to port-mapped to start FTP, uses VNN to improve download capability, uses address-mapped to start port 80, and so on. Fortunately all disadvantages will disappear when people use IPv6 Internet. And the IPv6-network will bring out a serial of advantages.With the quantity of using PDA , 3Gphone, intelligent cars , intelligence appliances proliferate, every equipment needs a unique IP address . Now the Ipv4 Internet can't supply so many addresses. The only method is updating to ipv6 by using the ND (Neighbor Discovery) precept.But the new protocol is not compatible with ipv4; the coexistence of IPv4 and IPv6 network will perdure. Then one of key points is how to upgrade to IPv6 network. This article compares these disadvantages by introducing all methods of upgrading network protocol. Nowadays few institutions have connected the IPv6 network. Many IPv6-hardwares are not manufactured; especially common hard wares cannot work accurately on IPv6 protocol. That is to say we have to update the stabile using hard wares. These mainly refer to routers. As the using number of mobile equipment is less than pc now, discarding the old maturity is unadvisable. But the process of building IPv6 network will be very complex and expensive. In this article there exists a method to build IPv6 network by starting the RAAS, and the communication of IPv4 and IPv6 nodes is implement. This article used normal camera to collect video signals, utilizing DirectX SDK to capture and display video signals. The control channel adopts TCP protocol, and the data channel adopts UDP protocol.This article points out that using pc-router to transmit the IPv6 data packages under tunnel is possible; the experiment is very versatility for using Microsoft DirectShow. So this article will help the forth coming IPv6-network, and may guide the process of network development or remote control the numerous intelligence application , mobile network-phone, all kinds of junior apparatus.
