DDS and RTPS protocol analyzer

Does anyone know if a protocol analyzer exists for DDS and RTPS (Real time Pub Sub) - https://en.wikipedia.org/wiki/Data_Distribution_Service and http://www.omg.org/spec/DDSI-RTPS/

If not, can someone point me in the right direction for how I could go about building one ? Is BinPAC the right place to start ?

Appreciate any help !!
