The dissertation is an attempt to analyze China’s postcolonial condition as reflected in Chinese-English website translation against the background of the exponential development of information and communication technology (ICT).

After analyzing the disadvantage of traditional way of Web page translation,gives the new resolution based on the mechanism of content negotiation and Web cache,which makes the translation service invisible to the client,saving the add.

Study on NAT-PT translation gateway based on Click modular software router system;

The design and realization of IPv4 to IPv6 translation gateway;

In this paper , we describe in detail the translation gateway which is based on NAT-PT technology, we present an implementation of NAT-PT gateway,for IPv4 moving to IPv6 based on Linux.

Also a re-ranking algorithm is proposed,which use SIFT local features of the images to construct visual graph among images so as to cluster the images,in the same time Web Explanation of keywords is introduced to enhance the efficiency of retrieval.

Some technologies to resolve network address translation traversal problem in next generation network system are introduced.

It was introduced the network address resolution with technical angle, introduce the function and implement method of network address translation(NAT).

During this transition, Network Address Translation (NAT) decreases the needs of IP addresses for our word and gains much valuable time to prefect IPv6.
