Protocol Reader ® is a powerful protocol analyse tool for parsing and displaying received binary messages. With an easy-to-use interface and programable kernel, it can support variety of protocols such as IP based protocols(TCP,UDP, etc), Telcomunication protocols (MTP3, ISUP,TUP, etc), or you can define new custom decoders of non-standard or rare protocols. Unlike other protocol analyzer tool, we provide advanced features to meet future needs, not only for standard protocols, but also for user-defined protocols.
