Abstract: By building the environment of the protocol analysis, this paper analyses the protocol of the Fetion Instant Messenger(IM) of China Mobile and summarizes the protocol formats of the text information and file transmission. Based on the protocol analysis, it designs and implements the monitoring system of the Fetion IM of China Mobile with Network Driver Interface Specification(NDIS) technology, which can supervise the text information and file transmission effectively and intercept the deleterious information in real time.

Key words: Instant Messenger(IM), Fetion, protocol analysis, Network Driver Interface Specification(NDIS), monitor
