Research on Information Search Engine

Based on GRID, CERNET can provide computing services and large distributed search engine, content delivery. In 1996, CERNET jointly proposed the Chinese first Internet standard, RFC1922 which can be used for the transition between different Chinese encoding systems. In 1997, the search engine named Network Compass was developed for both Chinese and English, which is used over CERNET.  In 2001, the IPv6 search engine was developed.

Research on Traffic Control and Monitoring and Network Billing

In 1996, CERNET began to research and develop the network billing system based on network traffic. In January 1997, this system was used over CERNET.
