Seagull is a free, Open Source (GPL) multi-protocol traffic generator test tool. Primarily aimed at IMS protocols (and thus being the perfect complement to SIPp for IMS testing), Seagull is a powerful traffic generator for functional, load, endurance, stress and performance tests for almost any kind of protocol.

In addition, its openness allows to add the support of a brand new protocol in less than 2 hours - with no programming knowledge. For that, Seagull comes with several protocol families embedded in the source code:

* Binary/TLV (Diameter and many 3GPP and IETF protocols)
* External library (TCAP, SCTP)
* Text (XCAP, HTTP, H248)
