Abstract: Gateway strategy and multi-protocols client strategy are the two main solutions to implement the interconnection among IM systems at present. The multi-protocols-based Pidgin realizes IM interconnection to some extent. But Pidgin's practical functions are limited by its disadvantages that lie in weak modifiability, poor scalability and inconvenient deployment. Based on SOA, an open-source multi-protocols IM system was established via reconstructing and reusing the Pidgin. This IM system is easy to modify, extend and deploy.

Key words: Instant Messaging, Interoperability, SOA, Pidgin Software
