Deployment Strategies: Translation Techniques

With advent of theIPv6 the people are converting there systems to it, but it is not so easy task to do so as there are multiple factors that are responsible in transferring all the IPv4 protocols to IPv6. Many simple and difficult solutions have been proposed to solve this problem. Other then converting all the protocols to the new IPv6 the companies can also use the technique of translation in such a way that they can run IPv6 internally in there system for some time and can use some type of translator to convert the IPv4 protocols rather then changing the whole system.

There is a little problem with this technique but that is no such a big problem the problem is that it discontinues the end to end connectivity of the network that is important in the data transmission. A solution to this problem is that you can use Network Address Translation – Protocol Translation that is very useful. To solve this problem many processes are under work and a solution will be provided in near future.

The translation mechanism is as follows with protocols

1.    Network Address Translation-Protocol Translation (NAT-PT)
2.    TCP-UDP Relay
3.    Bump-in-the-Stack (BIS)
4.    Dual Stack Transition Mechanism (DSTM)
5.    SOCKS-Based Gateway

The above translation protocols are more helpful when you are using IPv6. The protocol mechanisms are of two kinds. One those that do not need any changes either it is IPv4 or IPv6 and the second those that cannot work without changes. The example of the first kind is the TCP-UDP Relay mechanism which works on a committed server and transfer the data between the two own its own path. The example of the second type is latter the BIS mechanism  which needs some extra layers of protocol to work with IPv4
