23、oses (TPs) for the IPv6 Core standards. The TDs are presented in the tabular form specified in ETSI TS 102 424 1 and the TPs are defined using the TPLan notation also described in ETSI TS 102 424. The Test Suite Structure is based on the IETF RFCs which, together, form the IPv6 Core specification an
