Seagull是一款IMS EPC等信令模擬器，通過腳本配置交互場景，做Diameter SIP H248等LTE協議的壓力測試工具。 Seagull is ahttp://gull.sourceforge.net/ free, Open Source (GPL) multi-protocol traffic generator test tool. Primarily aimed at IMS (3GPP, TISPAN, CableLabs) 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/benchmark 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, Radius and many 3GPP and IETF protocols) ?External library (TCAP, SCTP) ?Text (XCAP, HTTP, H248 ASCII)
