IPv6 Deployment Strategies: Tunneling Techniques

The IPv6 has introduced many different techniques of data transfer. One of them is tunnel transferring mechanism. This technique includes creating of tunnels manually according to your choice that include the IPv6 protocols taking over the IPv4 protocols. There are two types of tunnels that can be established, one automatic and second semiautomatic. The semiautomatic tunnels are used in the stock houses where there is only one way transmission while automatic transmission is used where there are IPv6 and IPv4 protocols being followed. The semiautomatic system needs to be configured at the both ends while the automatic transmission only needs to be connected to the network and continues the transmission until it is quitted.

The tunnel broker service is provided by the network provider himself. A semiautomatic configured tunnel is equal in working of a stable link among the two protocols IPv6 and IPv4 backbone. The main use of the semiautomatic system is that it handles the security of data from the beginning to the end.

As far the tunnel system that is available it can only work if the IPv6 and IPv4 are in the perfect form of dual stack. This is because the respective tunnel exists between only these two routers, adding the both routers means that you are adding the tunnels and they will go at the same path irrespective of the data they contain in the router. If you have more tunnels and more protocols it is difficult to handle and the system load will increase which may result in the traffic congestion. On the stating end and the receiving end you have to configure the addresses. So that it can match the data packet and allow it to pass through the router. It is possible for you to protect the IPv6 and IPv4 by taking the help of crypto map. Sometimes It may not be possible under some circumstances.
