Conformance Testing of Multi-Protocol IUTs

To declare conformance of multi-protocol Implementation Under Test (IUT), every layer of the multi-protocol IUT should be tested. According to ISO9646, single-layer test method is applied to testing the highest layer of multi-protocol IUT and single-layer embedded test method is used for the layers other than the highest layer because the interfaces between layers are not exposed. So far the conventional researches have focused on testing layer by layer all the protocols in a multi-protocol IUT.
